Micro Powder Roller Mill

The micro powder roller mill is a new type of high-fine grinding equipment. Its product fineness can be adjusted from 325 mesh to 2500 mesh according to the requirements of the customers, and the fineness can be up to D97≤5μm at one time. This micro powder grinding mill has comprehensive mechanical crushing properties such as rolling, grinding, etc. It is widely used in high-fine grinding of various non-metallic minerals such as talc, calcite, calcium carbonate, dolomite and kaolin, whose Mohs hardness is less than 5 and humidity is less than 5%. Due to its excellent performance, micro powder mill becomes more and more popular on the market.

Features of micro powder roller mill

  1. Taking into account the product granularity,the size of finished products is uniform and fine. Compared with other grinding equipment, the ultra fine grinding mill can produce 325 mesh to 2500 mesh product fineness at one time, taking coarse powder and fine powder into account. the product particle size is uniform, and it widely used in many fields, such as paint, plastics, high-end coatings, etc.
  2. Low investment cost and high production efficiency. Under the condition of the same production fineness, the investment cost of fine powder grinding machineis low, the return cycle is short, and the fineness efficiency of finished product is about twice as high as that of other equipment.
  3. Easy maintenance and simple operation. The ultra fine powder grinderadopts the high hardness wear-resisting material developed by the company to ensure the uninterrupted operation of the equipment. Simple structure makes that you can replace wearing parts, reducing maintenance costs.
  4. The production process is environmentally friendly and pollution-free. Dust collector has high dust collecting efficiency, which ensures no pollution during operation. In addition, the main engine and the fan are respectively installed with silencer room and silencer to reduce the production noise.

Technical parameter

Before you buy a micro powder roller mill, you need to know the difference between different models in order to choose the most suitable machine. Of course, the quickest way you can do that is by looking at the technical parameter. From the parameter table of fine powder mill grinder, you can learn more details about this machine. DR series grinder for fine powder is the hot sale.

Let’s take DR-198 as an example. The roller number of DR-198 is 28pc. Its Max. Input size is 10mm. If the customer wants the particle size between 5μm to 50μm, the production capacity of this model of roller mill can reach 800kg to 7000kg.

Taking the processing of calcite as an example, the output of different materials is different. If you require the product fineness is 325 mesh, the output of DR-198 is 6000kg to 6500kg. If want the product fineness up to 1500 mesh, its output is 1500kg to 1800kg. In addition, if you want to know more details, welcome to consult us now.

Its working principle

Jaw crusher machine breaks the material into less than 10mm of material, and then by the bucket elevator to the storage hopper. Then, the material in the storage hopper is fed into the main machine cavity of the micro powder roller grinding mill for grinding by the feeder. The material passes through the gap between the grinding roller and the grinding ring. The crushing and grinding function is achieved by the rolling of the grinding roller. What’s more, the roller is arranged in four layers so that the material can be fully ground to obtain the desired fineness of the product.
