Ultrafine mill is based on years of accumulated mill production experience, absorb the advanced mechanical manufacturing technology, a new type of powder processing equipment and testing and improvement after years of development. The ultra fine mill is widely used in paints, paper making, pigments, rubber, plastics, fillers, cosmetics, chemicals and other industries.

Ultrafine milln line roughly composed of Hubei broken machine, bucket elevator, storage hopper, vibration feeder, ultrafine grinding, host frequency classifier, cyclone powder collector or pulse dust removal system, high pressure blower, air compressor, electric control system etc.. The material is broken into smaller pieces by cone breaking.

The material by breaking machine was first broken into smaller pieces of material, hoist material into the hopper, hopper after vibration feeder material quantitative, uniform into Ultrafine milla-fine grinding mill crushing cavity material is the fineness of grinding, after crushing the material with the fan airflow into in powder selecting machine classification.

The size of the particles and the rotation speed are different, so they can be separated. The material that meets the requirements of size is passed through the separator, and then separated and collected in the powder collector, which is finished by the lower part of the powder collector. The meeting which does not meet the requirements will be re - milled into the Ultrafine milll it can pass through the separator.

The whole production line of ultra fine grinding is carried out under the condition of closed, circulating and negative pressure.

With the intermittent propulsion of national infrastructure construction, the application of sand making machine in sand industry is wider and wider. To efficiently and safely produce high-quality sand, it is very important to correctly operate this sand making plant. We will explain what should be paid attention when operating sand maker.

1. Before starting, check whether the observation door of the vortex motion chamber is tightly closed to prevent materials from rushing out and cause danger.

2. Check the rotating direction of the impeller. Seen from the direction of the feeding mouth, the impeller should rotating in the anti-clockwise direction, if not, adjust the connecting rod of the electromotor.

3. The correct starting order of sand making plant and conveyor equipment should be: ore discharging equipment-sand maker-feeder machine. The sand making equipment should be started with empty load and be fed with materials after normal operation. The stopping order is just the opposite of starting order.

4. The feeding granularity should conform to the standard, and materials bigger than the standard are forbidden to go into sand maker, otherwise it will cause unbalance and overdue abrasion of the impeller and even block the impeller pipe and central feeding pipe, and sand making equipment will not work normally. If large materials go inside, immediately discharge them.

5. When discharging equipment stops, timely stop material feeding, otherwise the impeller will be crushed and the motor will be burnt down.

6. Material feeding must be even.

7. In the running process of a sand making plant, if there is fierce vibration or abnormal noise, immediately stop the machine for examination, otherwise the impeller will be damaged.

8. Timely add lubricating grease to the machine and use dry oil lubrication. The adding amount should be 1/2-2/3 of the cavity of the bearing.

We hopes that the above advice can help customers to correctly operate a sand maker and reduce the failure in the using process to contribute to the fast development of infrastructure construction.

Due to the recent China's construction, water conservancy and other aspects of the construction, increase the demand of domestic sand, sand industry very influential; rise sand industry, the mining machinery industry of sand making machine, processing equipment and technological process of research and improvement. As an important part of sand and gravel production line, sand making machine is very important for its stability and durability because of its important position in the production of manufactured sand.

The mechanism of sand production line can not only provide high-quality aggregate for highway, railway, high-rise buildings, municipal engineering, hydropower dam construction, port, concrete mixing station, and increasingly become the main stream of production equipment of metal ore, quartz sand, slag processing and other fields, has become the core mechanism of sand and stone plastic industry field the.

Technological process

First of all, the material into the jaw crusher preliminary broken; secondly, the coarse material produced by belt conveyor to the crushing machine for further broken, then after crushing sandstone vibrating sieve into two kinds of gravel, sand sand mechanism to meet the feed size of sand making machine, another part of the material to return again into fine broken.

Part of the sand machine's material is made into sand, washed by sand washing machine (optional) and made into finished sand. The other part of the machine is broken again, and the final output of all kinds of machine-made sand meets the requirements.

Process characteristics

1. the product is cubic, strong and excellent, with low content and strong compression capacity, which is suitable for high standard construction, such as water conservancy, bridges, highways and high-rise building industries.

2. the mechanism of sand production line is suitable for granite, Xuan Wuyan, river gravel, aluminum, cement clinker, quartz stone, Jin Gang sand, sand, iron ore and other raw materials are broken, the traditional customer service mechanism of sand production equipment is only applicable to soft material crushing shortcomings.

As one of the important basic materials in the construction industry, sand and gravel will contribute to the construction of China. As a manufacturing machine for sand and gravel, the sand making equipment provides sufficient raw materials for the building. Now, the development of the mine concrete and construction industry is very rapid, which has added power to the sand and stone industry. Natural sand is now unable to meet the demand of the market, and it needs mechanism sand to help its development. The mechanism of sand compared with natural sand, the availability of more, especially in the building construction, it shows a great advantage.

Because of the demand of the market, the important position of the sand and stone industry is not to be underestimated. However, with the rapid development of China's economy, at present, there are many problems in the sand and stone market. We need to pay attention to it.

First, the scale of sand making enterprises is small. There is a lot of demand for the mechanism sand, but the market is obviously not able to meet the demand for use, which needs to be improved. The management level of many manufacturers is low. Many system sand making machine manufacturers now unexpectedly also depend on the nature of mining, this model of development is very terrible, because of the limited resources, it makes the development of these manufacturers limited.

Second, the means of mining are relatively backward. Now is the high-tech era, and the advanced production technology is productivity. If we want to get a high level of production and productivity, we must increase our efforts in importing the machine. Moreover, the mechanization and automation level of the sand making industry is relatively low, which brings trouble to the development of the factory.

In view of this, the manufacturing enterprises of sand making equipment have a lot of space to develop, because the demand for users is growing rapidly in the future. At this time, the sand making machine manufacturing enterprises should develop steadily, ensure the quality of the machine, let users have no worries, and guide the enterprises to develop in the right direction.

Third, in order to develop more long, the production standards of sand making enterprises should be more perfect. Relative to other industries, the policy and planning of sand and stone are less, and some of the policies and relevant regulations are relatively backward. So, this requires the workers in the industry to work harder to prepare for the standardization of the sand machine.

With the progressive movement of the milling industry, the raw material processing industry has reached an international level. The ultrafine mill is also becoming more and more high in the machine grinding industry. In order to meet the demand of the market, the ultrafine grinding machine gradually has the trend of scale development. Let's get to know the features of a large ultrafine mill. This will help us to get a better understanding of the large grinding machine.

First of all. the remarkable feature of the large ultrafine mill is that its production capacity is increased, that is, the increase of the grinding capacity. But according to the powder yield per unit time, the production of large equipment is equivalent to 6 conventional equipment. Therefore, in fact, the device can greatly reduce the area of possession, thus saving the cost of the use and investment of the workshop. Such a huge factory installation function can bring more benefits to the enterprise.

Secondly. the mechanical structure of the new ultrafine mill is the rule of the new grinding equipment. During the running process, the grinding roller and the grinding ring can always maintain a balance. This forms the linear structure of the grinding zone. With the same energy consumption as the traditional production equipment, the production can reach thirty percent to forty, thus greatly improving the production efficiency of the enterprise.

Third. the equipment of the large ultrafine mill is made up of the whole molding. So the whole seal is strong and can not produce any dust spatter in the process of production. In addition, the outlet of the fan is equipped with a pulse dedusting cleaning device, and the dust collecting efficiency can be as high as 99.99%. Therefore, it is a very environmentally friendly production equipment, it can achieve dust free processing operations.

Fourth. the structure of the large ultrafine mill uses a new seal design. The roller device can automatically add lubricating oil after 1000 hours of work, so that the safe and reliable operation of the equipment can be fully guaranteed. Besides, the mill assembly device makes operation, maintenance and replacement work more convenient, and the grinding ring replacement operation is more convenient. It does not need to remove the grinding roller, and can carry out lubrication and simple maintenance and cleaning operations.

The ultrafine mill is mainly suitable for the some ore and nonmetallic materials. Its application is very extensive, and it can be widely applied to various industries that need grinding operations, such as paper making, cosmetics, medicine, food, chemical industry, metallurgy and so on. Ultrafine Mill is made up of a number of production systems, such as grinding system, powder selection system, pulverizing system and dust removal system. The fineness of the finished product is very high, so it can be used for high quality cosmetic raw material grinding and drug grinding. Its environmental protection effect is very good, can meet the requirements of the home standard, the cost of investment is also low, so it is widely accepted by the users. Now, the ultra-fine grinding machine has become a widely used grinding equipment in many new industries, and it has also become the mainstream grinding equipment.

For large equipment, the operation is a very important work, reasonable operation can not only reduce the failure to make the production smoothly, but also can reduce downtime, will also reduce the probability of the accident, so as to guarantee the use of less cost in production investment. Especially for pulverizing equipment, ultrafine grinder is a large fine operation equipment. In the production process, it is more necessary to strive for improvement in operation, and strive to operate properly and correctly, and avoid serious consequences due to a little mistake.

In addition, the basic nursing work of the ultrafine mill should be done well to better ensure the efficiency of the ultrafine mill. So, we should do the following.

1. we should understand the relevant operating rules of ultra-fine grinding equipment, and the maintenance of it should be regularly implemented. For example, mechanical inspection, parts adjustment, and so on, according to the actual use of the situation to rationally arrange the strength of maintenance.
2. the installation of ultra-fine grinding equipment should be done well. According to the installation diagram of the supporting device, each component will be installed smoothly to fully cooperate with each part.
3. regular lubrication ultrafine grinding machine and replacement parts. Only the correct mechanical nursing, can prolong the mill fundamentally life, improve its efficiency.

The increase of high-pressure Raymond mill speed and inclination, will make the quality of the material flow increases, the residence time is shortened, this is because as the speed increases, the number of materials per unit time into the material layer of the active layer increased, per unit time of material axial displacement increasing material axial movement speed increase, and material quality increase the flow of material, shorten the residence time.

With the increase of the inclination of the kiln, the speed and gravity component of the high speed Raymond Mill increases along the axial direction, and the velocity of the material moves along the axial direction, and the residence time of material is shortened, and the mass flow rate of the material increases. With the increase of kiln stopper lost height, mass flow rate increases, the residence time is shortened. The height of the retaining ring increases by 1 mm, the material mass flow will increase by 1% to 2%, and the residence time will shorten by 0.15% to O.25%. However, the relationship between the height of the retaining ring and residence time remains to be further verified. This is because the installation of the tail gear ring affects two aspects of the residence time.

On the one hand, the height of material accumulation at the end of the feeding pipe increases, and the slope of the material layer increases, which is equivalent to the increase of the kiln inclination. The axial movement speed of the material increases and the residence time of the material decreases.

On the other hand, the thickness of the material layer is increased, the cross section area of the particle flow is enlarged, the axial velocity of the material is reduced, and the residence time of the material is prolonged. The lengthening and shortening of the material residence time depends on the comprehensive effect of these two aspects. For the test chamber of the variable diameter kiln, the residence time of material decreases with the increase of the height of the retaining ring of the kiln, indicating that the former has greater influence on the residence time than the latter.
