Mining crusher(namely mining machine) is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry in many countries. China basalt stone production line is earliest one that enters into Africa, and favored by the African people. Following are some useful informations of the basalt mining.

Basalt is widely used in mining industry. It is most commonly used for crushing aggregate in construction projects. Crushed basalt is used for road base, concrete aggregate, asphalt pavement aggregate, railroad ballast, filter stone in drain fields and may other purposes. Basalt is also cut into dimension stone. Thin slabs of basalt are cut and sometimes polished for using in floor tiles, building veneer, monuments and other stone objects. In asphalt concrete of the highway surface, the pavement of the way has high requirement on the shape and rank of the basalt. Especially to the content of needle plate type in the basalt, the former impact crusher processing chart cannot meet the requirement any longer. Therefore, our company puts up the newest crushing and screening product ( VSI series of vertical shaft impact crusher) to meet the need. The high-quality aggregate produced by this production line is widely used in road surface of many highways.

Basalt stone is a major material to produce cast stone, and basalt fibers can be used in various branches of mining industry, it is very important to choose a suitable basalt machine. At the same time, basalt stone can be found everywhere. So basalt crusher and screening is popular. our company also designs many kinds of basalt crushing equipment for the clients. In basalt crushing and screening plant, basalt stones firstly be fed into primary jaw crusher for primary crushing by vibrating feeder, then the crushed basalt stone will be enter into impact crusher or cone crusher for further fine crushing via conveyor belt. According to the clients' demands, VSI series crusher will be used to shape the sized basalt stone in cubical shape. Finally, vibrating screen will sieve the sized basalt stone into different piles.

As the leader of the domestic mining machine, our company actively participates in the international competition in recent years, the exports quantity of our company crusher equipment increases year after year, and it has become a hot-selling product in the African market.

The ultrafine mill gypsum powder production line designed by Shanghai Shibang is developed by Shibang experts based on the experience of ultrafine powder technology research and development for nearly 30 years, combined with the various characteristics of gypsum powder. The production line is equipped with Shibang's advanced grinding equipment, including HJ high-efficiency jaw crusher, SCM ultrafine mill, as well as supporting equipment hoist, storage bin, vibrating feeder, conveyor, pulse The dust collector and so on, the whole production line has reasonable design and excellent performance, and the advantages in grinding efficiency and gypsum powder quality are very obvious.

The specific process of the ultrafine mill gypsum powder production line can be subdivided into five major systems: crushing system, storage conveying system, grinding system, calcining system and electronic control system. The key system that relates to production efficiency and finished product quality is the grinding system. Then, the detailed process of gypsum ultrafine powder production is as follows: HJ jaw crusher breaks large-sized gypsum ore into small pieces of less than 30mm, and then transports it to the SCM ultrafine powder mill by the conveying system. After grinding, the pulverized particles enter the classifier, and the gypsum ultrafine powder that has reached the required fineness of the product is separated and sent to a boiling furnace for calcination, and the unqualified material is returned to the mill for grinding again until it is qualified. The qualified gypsum powder after calcination is sent to the clinker storage or directly to the product workshop for use.

After the ultrafine powder of the ultrafine mill production line, the product fineness can reach between 325 mesh and 2500 mesh, and the whiteness is good, no impurities, and the application prospect is very broad. Before the ultrafine mill gypsum powder production line, gypsum was only used to prepare chalk, putty, tofu and so on. Now, under the technology of Shibang ultrafine mill gypsum powder production line, it can be used in many fields such as building materials, construction, power plants, papermaking, medicine, etc., and the application value is greatly increased.

When using large production equipment such as Raymond Mill, there are a lot of operation precautions, which are also to be done, and the same are some operations that can not be carried out, which are also prohibited. Only by doing these operations well can we ensure the smooth production of the mill. This article is to introduce the problems of the prohibited items.

1. Do not read the manual before operation

We know that when the Raymond Mill leaves the factory, there will be a manual about the operation, that is to say, some instructions about the addition of materials and the adjustment of machine parameters, etc., but many workers start to produce without reading the manual, so it will cause frequent failures of the equipment during production, which greatly affects the production To the service life of the machine, as well as production efficiency;

2. Equipment on load start

In many cases, there will be some materials in the grinding chamber during the use of Raymond mill, but the staff did not discharge them. The next day, they did not discharge them first, and directly started the operation. This situation is very easy to cause serious damage to the inner part of the mill and parts, increasing the maintenance cost;

3. Unqualified power supply

During the production of Raymond mill, the power supply is mainly to provide power to help it operate better. Different types of equipment have requirements for power supply. If the power supply is unqualified, it cannot provide the necessary power and the machine cannot work smoothly;

4. Improper wearing of personal protective equipment

The grinder is a large-scale mining production equipment, so it will produce a lot of noise in the work. In addition, because the raymond grinder equipment is for the processing of fine powder, so the separation problem in the production is inevitable, so the staff need to wear more perfect protective equipment, otherwise it will cause great harm to health;

5. Use only without maintenance

In the production process of fine powder, the internal parts will be damaged, which will affect the service life of the machine. Therefore, operators need to regularly maintain all parts of the mill, which is an effective scheme to extend its service life;

At present, ore mill holds an important position in the ore dressing equipment and its efficiency directly affects the whole production process. Then, what are the factors affecting the production efficiency of ore mill? As an experienced professional mining equipment manufacturer, our company will explain in detail:

1. When grinding mill materials with smaller particle size and low hardness, if the ratio of small balls is small, the product granularity may also be coarse. Thus small balls should be properly added to adapt to the nature of ore to get good product fineness. Therefore, the balls must be filled strictly according to proportion, and avoid ratio imbalance; when dealing with materials with large particle size or hardness, the low ratio of big ball may lead to coarse product, and the handling capacity will also be limited and the grinding efficiency will be influenced.

2. The feeding speed is the amount of ores that go through the ore mill in unit time. When the feeding speed is very slow, the ore amount in the ore mill is small, which not only leads to low productivity, but results in empty grinding and causes serious wear and over crushing. In order to make ore mill work effectively, high feeding speed should be maintained to keep more ores waiting for grinding inside the mill.

3. With the increasing of feeding speed, the content of qualified grain in the discharged ores reduces while the output number of qualified grain increases, so the ore grinding efficiency increases significantly. If the feeding speed exceeds a certain quota of ore mill under the specific operating system, the ore mill will be overloaded and discharge steel balls, spit out large ores, pour pulp and even be blocked. Therefore, the feeding of ore mill must be continuous and even, otherwise it may have bad influence on the ore beneficiation.

The jaw crusher mainly uses the striking force of the movable jaw and the impacting force of the fixed jaw to achieve the crushing purpose, during the process, the jaw plate of the jaw crusher is plays an important role. The most common malfunction of the jaw plate is breaking. After eliminating the aspect that the jaw plate manufacturing technology of the c6x jaw crusher manufacturing company is not eligible, the breakdowns of the machine itself can be divided in to several types. The size of the material discharging mouth of the jaw crusher does not conform to the standard, so that when some big materials go into the crushing chamber, the load of the jaw plate will increase. The casting of the jaw plate has serious quality defect so that there is no quality guarantee for the jaw plate. If the quality of the toggle plate and the toggle plate mat is not qualified, when there is powerful impacting force and the jaw crusher needs self-protective operation, the toggle plate will not be able to break down itself in order to protect itself.

There are some other personal factors that may influence the jaw plate. After the pull-rod spring inside the machine is used for a long time, the tensile force will lose efficacy but the workers do not change the spring device timely, or the assembly of the eccentric shaft, bearing and the fixed lining and the movable is not eligible, so that the movable jaw changes its position during the working process, and it breaks impacting with the in-wall back-plate of the equipment. If the materials are fed unevenly, then the abrasion impacting strength will be increased.

During the daily production process, the workers should try to avoid the negative factors such as the damage of the jaw plate and the decrease of the service life of the machine. Only in this way can the production efficiency of the jaw crusher be greatly improved.

The solution to the break of the jaw plate of the jaw crusher: change new jaw plate for the jaw crusher, and at the same time, pay attention to the granularity of the materials that are fed into the crushing chamber. And according to the crushing ability of the crushing equipment, the workers should feed materials in a suitable manner in order to prevent some uncrushable foreign materials go into the crushing chamber. If the toggle plate mat is abraded, then change new one and keep the toggle plate and the toggle plate mat in a parallel position.

Our company is a large-sized sand maker manufacturer, and our sand maker has many advantages such as simple and reasonable structure, high independent impact crushing ability, super low operational cost and the most competitive price.

With the rapid development of urbanization, there is more and more construction waste in cities, which is a big problem of the government. Currently, the construction waste problem is increasingly exposed, so a lot of cities have purchased the mobile crusher machine to solve this problem. What we did not expect is that the working ability this kind of equipment is strong, which is flexible for the disposal of construction waste. What are the key points we need to notice during the operation of mobile crushing station?

The first is to use different equipment in different periods, so as to improve the utilization rate and working efficiency of the machine. Because the mobile crusher consists of coarse crushing, medium crushing and fine crushing, you should choose the suitable equipment according to the sizes of the materials. You should pay attention to the surrounding people on the operating site to ensure the safety of the surrounding circumstances, after that, the machine can be started. Do not allow non professional personnel to operate, repair or maintain the crusher. If the spare parts are damaged, you must contact with the manufacturer of mobile crushing station, please do not produce or modify the spare parts yourself.

When operate the construction waste mobile crushing station, you should select the waste first. Remove the materials which cannot be crushed such as steel. If not taken out, it will cause great damage to the machine. When the rubbertyred mobile crushing station is operating, operators must pay attention to the quality of materials, whether there is no change. If there is any variation, or the discharging speed is slow, the crusher should be shut down to check whether there is any blockage or sieve breakage phenomena. Then carry out the corresponding repair or the replacement of damaged parts. During the operation of the mobile crusher, the operation personnel must pay attention to the voice of the machine, if there is an exception, stop and check the machine immediately.

Our company produces two kinds of mobile crushing stations: rubbertyred mobile crushing station and crawler type mobile crushing station, which are the best weapon for processing the construction waste, and it is the integration of feeding, crushing, screening and conveying. Construction waste is crushed into recycled aggregates with the help of the mobile crushing station. If fly ash, cement and other additives are added to the aggregates, 15 kinds of green building materials such as unburned brick, grass planting brick, brick plaza, permeable brick and road brick can be made to promote the development of domestic construction waste recycling.
