Judging from the coal industry, it is learned that China will create new coal mine with size about 300 million tons, and industrial restructuring will occur by strong integration and retrofitting existing coal mines, closing small coal mines, eliminating coal mines with backward production capacity, so as to accelerate the construction of large coal mining bases and large modern coal mining, which will provide good opportunities for development of coal mining machinery enterprises in China.

Coal is the primary energy in China, and material base indispensable to the national economy and social development, so coal occupies an important role in Chinas energy structure. Entering the 21st century, coal industry has made rapid development in China. Coal is an important basic industry, and Chinas coal production ranks the first in the world, so China is a coal-producing country, China coal industry now has the ability to design, construct and manage open-pit coal mines and large and medium mines. Modern mechanized equipment, efficient fully mechanized driving equipment and large open pit stripping, mining, transportation, and other equipment will be used more in large and medium coal mines.

Mining machinery and equipment is used for serving mineral resources companies, so mining machinery industries are on the same chain with coal, iron ore, zinc and other nonferrous metals. From the perspective of industrial chain transmission, the boom of mining industry will tend to pass to the mining machinery and equipment industry. The boom of mining will trigger the industry to put more capital and increase exploration efforts in mining mines, expanding demand for mining equipment. Meanwhile, the scale of mineral development also increases the demand for mining equipment.

Recently, mining machinery and equipment stocks ushered in the new opportunity to rise. Some media reported that mining machinery is facing a new round of industry needs, especially crushing machine, grinding machine, ore dressing machine, cement making machine and many other devices.

Mining machinery is an equipment industry with various machine types, complicated equipment structure, high demands and wide application among the engineering machinery industries. According to its application, mining machinery can be divided into excavation equipment, elevating equipment, narrow-gauge transportation equipment, crushing and powder grinding equipment, mine screening equipment, washing equipment and calcinations equipment. The technical level of mining machinery in our country is backward and develops very slow. In recent years, with the increase in demand and the promotion of expansion of domestic demands, the government further strengthens the effort of independent research and development, so that the mining machinery develops rapidly. SBM grasps the rare opportunity and constantly makes innovations, and researches and develops a world-class portable crusher plant on the basis of stationary crusher equipment, making it a new crusher in the ore crushing and grinding industry.

Mining machinery mainly serves the fundamental industrial departments such as energy, transportation and raw materials and its main task is to provide advanced and highly efficient technical equipment for the mine quarrying and the deep processing of raw materials of such departments as coal, steel, ferrous metal, chemistry, building material and nuclear industry as well as the construction of large projects such as railway, highway and water and electricity.

The combination of different types of crusher machines can form a powerful crushing production line to complete the work of multiple needs. Our crawler-type mobile crushing station has such advantages as advanced design, excellent performance, high production efficiency, convenient operation and maintenance, economic running cost and stable and reliable working condition. Compared with fixed crushing station, crusher mobile is just like a movable medium and small-sized crushing plant whose working efficiency and running cost are all superior to that of stationary crushing plant.

The successful research and development of mobile crusher promotes the development of mining machinery products to have the tendencies of digitalization, parallelism, integration and intellectualization. Among them, digitalization has become the core technology of realizing quick innovation and development. The improvement of information technology promotes the unmanned mining technology to develop from current automatic quarrying or remote quarrying with traditional quarrying technology as the core to unmanned mine with the main technical features of advanced sensor and detection and supervision system, intelligent quarrying equipment, high-speed digital communication networks and new type of quarrying technical process.

Load acting on mobile concrete crusher is actually the inertia force and inertia moment generated by movable vertebrae and vibrator, which is a cyclical dynamic load, therefore, it is inevitable to cause crusher vibration. Vibration forms of concrete crusher are vertical circular vibration, horizontal vibration, pendulum vibration, as well as extraneous vibration which is caused by intense shock and vibration, among which, horizontal circular vibration is principal oscillation, and other vibration forms are relatively small, so we here mainly talk about vibration isolation system of horizontal circular vibration.

Body of concrete crusher is located on the isolation system; if set shear elastic stiffness of vibration isolation system as K, total mass of material in concrete crushing machine as M, inertial force of concrete crusher in any horizontal direction as Fc, then the spring mass system of concrete crushing machine can be shown in the figure below.

The first part is self-vibration of inherent frequency Wn, AA is free vibration amplitude, A2 is initial phase of crushing motion. The second part is the forced vibration of inertial force w. As damping always exist in actual vibration system, so with time going on, free vibration part of the primary crusherwill decay. If Wn=w, the amplitude will be infinitely great, this phenomenon is known as resonance. When choosing vibration isolation system, inherent frequency Wn must be away from the inertia force frequency w, to avoid resonance. As shear elastic stiffness of rubber spring is smaller and affordable to multi-direction loads with large damp, it has good effect on absorbing shock and high frequency vibration and reducing noise, therefore, it is ideal to adopt rubber spring as vibration element of concrete crushing machine.

Crushing equipment plays a decisive role in the crushing industry, which is usually used to crush gravel, granite, basalt, magnetite, feldspar, silica, quartz, etc. But for these rocks with different hardness, some crushers cannot crush them successfully.The origin of rock crushing plant is relatively early in China, but in the technical aspect, it is not mature, for a long time, when buying crusher equipment, customers tend to the foreign brands. But after the progress, crusher equipment technology has been improved, and the previous technology obtained the innovation. SBM is specialized in the production of crusher equipment, which has introduced a lot of foreign technology, in addition, we also has a good master of the advanced technology to promote our products. For some rocks with large hardness, which is difficult to crush, compound crusher can successfully crush most of the hard rocks, such as iron ore, limestone, quartz, granite and cement clinker.

It is widely used in metallurgy, building, highway, chemical industry, building materials industry, which is suitable for crushing hard ores and rocks. Compound crusher has strong crushing strength, which has two kinds of crushing structures, which can be adapted to a wide range of production. When compared with the traditional domestic crusher, compound crusher adopts hydraulic locking, hydraulic adjustment and cleaning cavity devices, which has greatly increased the degree of automation. Compound crusher has high quality design and manufacturing technology, which can ensure the long service life of the crusher; the maintenance of compound is convenient with low cost, and all the maintenance work can be very easily conducted in the upper part of the machine.

With the technology innovation of crushing equipment, the types of crushers in SBM are various, which include compound crusher, impact crusher, jaw crusher, hammer crusher, cone crusher, etc. The crusher produced by our company has strong competiveness in the market, which has high quality, reasonable price and considerate

High-quality mining machinery machines are important embodiment of enhancement of national industrial power. In recent years, SBM constantly intensifies the efforts on scientific and technical innovation of drying equipment, crushing equipment, sand making equipment, etc, which makes full use of high technology to improve product performance and quality. Innovative research of coal crusher machine conducted by SBM not only increases core competitiveness of product, but improves technical content of equipment.

Gold is a significant performance of global currencies, and is the important national reserve assets, whose reserve directly affects national economy and inflation rate. So gold has been rushed in recent years, and mining gold has become popular in mining industry. However, goldmine will emit large amounts of waste residue after crushing, flotation, cyanide, restore and other processes, which contain some highly toxic cyanide and strong acids, if enters the water, it will be extremely harmful to people and livestock and crops.Therefore, How to deal with reasonably gold crusher is that the vital problem for mining manufacturers and experts?

After long research and experiment, the experts found that gold mine discharged some crusher with copper compounds, which of copper content is even up to 30%. If these coppers can be refined, it can solve effectively shortages of copper resources. Meanwhile, gold crusher can also be made into a new wall tiles after jaw crusher crushing, and vibration screen screening, which not only supply building materials, but also avoid environmental pollution, it greatly conform to the national energy conservation and environmental protection theme.

In order to realize the recycle of gold crusher, there are many crushing equipment for crusher, but gold crusher contains acidic substances, which has extreme causticity, so we must choose special crusher. Jaw crusher ,cone crusher, and impact crusher made by Henan SBM adopt international advanced technology and high quality materials, ,which have strong crushing capacity, high efficiency and corrosion resistance, and are widely used in iron ore, cooper ore, gold and silver ore, and other materials. They are the optical crushing equipment for dealing with gold crusher, are widely recognized by the market.

In the near future, SBM will research continuously crushing equipment, grinding equipment and improve old equipment, we actively comply with national sustainable development path and contribute their efforts to develop energy saving and environmental protection economy.

Fly ash has good uniformity, good bearing capacity, good water absorption and low requirements for construction. Fly ash can be used as road filling, which is not only environmental protection, but also can reduce the construction cost. Fly ash can also bring great social and economic benefits when it is used for road building. The comprehensive utilization of fly ash is one of the key industrial solid waste treatment projects in China. Fly ash has great value, which is a kind of renewable resources used in industry and agriculture, and it can play a greater role. At present, the fly ash utilization technology has matured, for example, it is used in building materials industry, which can make cement, fly ash brick, fly ash blocks and sheet metal, ceramic, concrete admixtures, fine aggregate, fly ash aerated concrete and lightweight heat-resistant concrete.

Our raymond mill has advanced technology, which focuses on the processing of fly ash to fully meet the customer demand for milling machine with high rate of finished products. The recycling of fly ash is more substantial, which can bring rich profit for our economy. In addition, the 'extraction' development and utilization of fly ash is a new method of extracting a variety of chemical products and rare metals from fly ash to 100 times improve utilization of fly ash. It is the inevitable development of science and technology industry, and the further affirmation of fly ash resource. In the future, the fine fly ash extraction and deep processing project will continuously turn waste into treasure, which has low investment, high output and environmental protection. It belongs to the comprehensive utilization of 'three wastes' treatment and the 'three wastes' resources.

SBM produces a series of Raymond mill, raymond mill, micro powder mill, etc. raymond mill can be used for processing coal gangue, which turns waste into treasure. According to the national recycling policy and guidance, power plants and coal gangue factory are required to reform technology for the equipment as well as the recycling of fly ash. Especially for the high utilization rate of fly ash, it needs careful arrangement to improve the utilization level.

Cone crusher is the commonly used crushing equipment. During its production process, the broken of shaft is a kind of common fault. The frequent broken of shaft will not only affect the normal production of cone crusher, but also increase its daily maintenance and repairing work. SBM will analyze the causes and solutions of this failure in the following paragraphs:

After the analysis, we draw a conclusion that there are three general reasons for the fracture of main spindle during the process of cone crushing machine in the long run: its quality, external factors and the fatigue of fracture. For the first two reasons, choose suitable materials according to the actual situation of the spindle to ensure the normal influence of external factors, which can avoid the fracture problem. But for third one, its reason is to feed on one side, which leads to the uneven distribution of materials in the crushing cavity. The imbalance of the load at the bottom of crushing cavity results in impact load of the spindle. Therefore, the spindle is periodically affected by the impact force during its eccentric rotation, so that the spindle will receive continuous bending, which is the reason for the fatigue fracture of the spindle. In addition, cone crusher can be modified to solve the problem of the broken spindle.

The baffle plate in the feeding hopper should be adjusted for the free fall height of materials, and then adjust the upper crossbeam to be parallel with the feeding direction. Maintain the packed feeding of cone crusher as possible as you can (packed feeding can maximize the productivity of crushers). With the improvement of these measures, the materials along the crushing cavity are uniformly distributed, which has greatly improved the stress condition of the spindle as well as its working environment and running status. After the improvement, the operation of crushing equipment will be in normal operation, which has achieved good results, such as safe operation, reliable quality and economic performance, high working efficiency and long duration.

At present, the crushing equipment in our country has been constantly developing and upgrading, and it has been better satisfying the specific needs of different customers. Industrial crusher machine has been widely used in such industrial departments as cement, chemical industry, power and metallurgy for the medium crushing and fine crushing of materials with medium hardness such as limestone, slag, coke and coal.

The constant development of black stone crusher machine industry is gradually influencing the position, current situation, market, development tendency as well as relevant policy and regulations of the industrial management and industrial policies of fertilizer, pesticide, fine chemical engineering, inorganic salt, organic raw material, rubber processing, chlor-alkali and chemical new material of chemical industry in the economy.

At present, the stone crushing plant industry, which used to belong to mining machinery industry, to constantly expand the market, begin to research new technology to seek new fields. SBM starts from coal, cement, ceramics, slag and steel slag and carries out the research of application technology of manufacturing technology and technical process with crushing plant, powder grinding mill and sand crusher as the main products. The new products researched and developed by our company through expanding innovative approaches can satisfy the more specific and more precise innovative contents of chemical materials for crushing equipment. All the products researched and manufactured by our company are energy-saving, water-saving, comprehensive utilized and environmentally friendly urgently needed by the chemical industry and can create a safe and comfortable working environment for the equipment operators, and the products include crawler-type mobile cone crusher, semi-mobile crusher portable, PFW European type deep-cavity hydraulic impact crusher, CS series cone crusher, VSI sand maker, MTW European type trapezoid powder grinding mill and so on.

It can be said that the development of stone crushing machine industry plays an important driving role to chemical industry. At the same time, our company also has crushers specially designed for super-large materials, hard material crusher and mobile construction station. In the mining industry, the material crushing method widely used is still mechanical crushing, mainly including squeezing, splitting, bending, grinding and impact crushing.
