But if there is a higher demand for fineness will have to consider ultra-fine grinding machine.
ultrafine mill work, the host motor through the reducer to drive the spindle and the turntable rotation, the turntable through the pin drive dozens of ring roll in the grinding ring rolling and rotation. Large pieces of material broken by the crusher into small particles by the hoist into the storage silo, electromagnetic vibration feeder to the material evenly to the middle of the upper turntable, the material in the centrifugal force under the circumference of the circumference, and fall into Grinding ring by the ring roller stamping, rolling, grinding and grinding, the material crushed by the first layer into the second and third layer, the pressure of the centrifugal fan suction the external air inhalation machine, and after The third layer of crushed powder into the powder machine.
SBM according to the various types of stone in a number of aspects of the production characteristics, integrated ultrafine mill production line of the overall advantages to the user configuration of the ultrafine mill production line, including a full set of crusher, bucket elevator, storage silo , Vibration feeder, micro-grinding host, frequency classifier, double whirlpool collector, pulse dust removal system, high pressure fan, air compressor, electrical control system and other equipment composed of a production line, this program configuration Also has a certain advantage exists, mainly in the following aspects:
1, ultrafine mill production line of the program, to the user's biggest advantage is to simplify the production process, the market we often see the production line in the production line, there are three, four broken to complete the entire production, Now SBM simplifies these production processes into two pieces of production, which can not only reduce the host equipment, but also reduce the crusher equipment and milling equipment between the feeding belt conveyor and these devices in operation The process of power consumption, wear-resistant parts and so on.
2, in addition to ultrafine mill production line configuration of the crusher and micro-grinding machine which can not only simplify the production process, colleagues can also achieve lower production energy consumption between 30-40%, so that the wear-resistant parts to reduce 70-80%, in order to achieve a total investment reduction between 20-30%.
Ultrafine grinding and ball mill is also a kind of grinding equipment, but it is mainly used for gravel production line, because the ultra-fine grinding without crusher crushing, you can directly deal with raw materials, simplifying the production process, and ultra-fine Micro-grinding grinding of the material in the particle size span is relatively large, and the smallest size than the ball mill small, so the production process is widely used. Then the ultra-fine grinding in the production process will have what problems, his maintenance method is what, then we introduce a few common problems to deal with.
1, ultra-fine grinding no powder or powder production less
2, ultra-fine powder grinding powder too thin or too thick
3, micro-grinding host current rise, machine temperature rise, fan current drop
4: ultra-fine grinding of the host noise, and the shock of the powerful.
5, ultra-fine powder grinding machine vibration powerful
6, fuel tank and transmission heat
7, ultra-fine grinding of the roller device into the powder bearing damage
In the use of mine resources, with the exception of a small number of minerals can not use the commonly used equipment processing, 85% of the ore resources are through the ultra-fine grinding machine processing, with its physical state of the powder posture to attack the market, And get their own proprietary performance. So the production efficiency of grinding operations is the focus of the production of manufacturers, then, how to detect ultra-fine grinding machine is "lazy" it?
First, the detection operation rate, that is, ultra-fine grinding machine working time ratio:
It refers to the actual working hours of the equipment for a month or a year as a percentage of the number of hours. The operation rate of the ultra-fine mill reflects its technical status, and its level reflects the management level of the staff. Which can also expose and analyze the reasons for the abnormal operation of the milling operations, to take effective measures to improve. Improve the operation rate of ultra-fine grinding machine equipment also increased the production capacity of milling workshop.
Second, the production capacity:
The production capacity of ultra-fine grinding machine, including production capacity, the use of coefficient, the specific size of the utilization factor. Only when the equipment model, specifications, ore nature, to the ore particle size and product size and the same requirements, the ultra-fine grinding capacity of the mill can be more concise review of the work situation. The use of the coefficient can only be in the ore particle size, product size are similar conditions, in order to more truly reflect the nature of the ore and the various conditions of milling. Specific grain size utilization factor can be more realistic to reflect the work situation, you can compare the different specifications, different particle size and product size of the work under the production capacity.
Third, the fineness and efficiency of milling:
Finished fineness is the production of ultra-fine mill, the daily inspection of another quality indicators. The fineness of the flour is usually sieved with the "sieve" of the "standard sieve" and is expressed as a percentage of the total amount of the product through the sieve (ie, the sieving rate). The higher the sieving rate, the finer the product The more production. Unit power consumption productivity can be more realistic from the energy point of view reflects the ultra-fine grinding machine work, therefore, energy and productivity can be linked to evaluate the work of equipment.
Ultra-fine grinding machine is the stone production line commonly used high-performance milling equipment, a wide range of applications, is China's high-fine powder production industry in the most commonly used milling machinery. In the milling machine for different materials for the production of fine powder, there will be milling machine finished powder can not be discharged or the feed at the mouth of powder and other powder into the phenomenon of less, greatly affected the smooth production. At this time to shut down the equipment in time for maintenance, to ensure the production of stable and efficient.
General ultra-fine grinding machine to meet the most common problem is the problem of uneven powder. So how to better solve it? The following Collier Machinery Co., Ltd. engineers for your detailed answer:
ultrafine mill in the feed if the material is uneven, will lead to the accumulation of materials in the grinding room, the material can not be fully grinding effect, which can not be normal discharge; ultrafine mill grinding powder Through the role of the blower in the circulation duct, when the blower air volume is too large, will cause the powder back, even from the feed port; ultrafine mill in the entire process is in a sealed environment, when the ultra-fine Grinding machine seal lax or lock powder sealing failure, will cause the wind down suction, affecting the smooth discharge of finished products.
Then how to solve it, is a crucial issue, when the ultrafine mill caused by the above situation caused by abnormal discharge, the need for downtime may cause trouble to troubleshoot and repair, to ensure that ultrafine mill feed evenly , Can not be a large number of feed or not for the phenomenon of material in the feed by checking the device ammeter changes in the instructions to adjust to avoid the phenomenon of material in the grinding chamber blockage; the blower air volume should be timely observation of ultra-fine grinding , Can not be too large to cause the powder material circulation too fast, not through the analysis of the analyzer in the circulating air duct continuous flow, can not normally discharge equipment; ultrafine mill to carry out regular checks on the seal, while ensuring the lock Lax, to avoid the phenomenon of suction suction phenomenon. In the equipment after a thorough inspection to ensure that the powder before they can start a normal production work to prevent the equipment and other production problems.
SBM Machinery have two basic equipment manufacturing factories.
