Basic conditions for selecting an ultrafine pulverizer

1. Material properties
The properties of the material include comminuted material properties and density. The pulverized material is brought out of the pulverizing chamber by the negative pressure air flow caused by the fan, and enters the material collection system. After being filtered by the filter bag, the air is discharged, and the material and dust are collected to complete the pulverization. Ultrafine pulverizer is a device that uses air separation, heavy pressure grinding and shearing to achieve ultrafine pulverization of dry materials. It consists of cylindrical crushing chamber, grinding wheel, grinding rail, fan, material collection system, etc. The material of the ultrafine pulverizer enters the cylindrical pulverizing chamber through the feeding port, and is crushed and sheared by the grinding wheel moving in a circular motion along the grinding rail to achieve pulverization. Grindability of the material greatly affects the handling capacity. Usually based on the actual results of processing the best way to determine the best way to use the shredder is to use a shredder in the grinding, computationally scaling the obtained experimental results for what kind of material is selected; or check the working refractive index of the material, per ton of material to get the power consumption mill and then determine the required mill size.

2. Material Status
This item mainly refers to the humidity and temperature of the material. Different from wet pulverization, in dry pulverization, if the moisture content of the enterprise material cannot exceed 3%, the processing capacity of the pulverizer will rise sharply and decline, especially the dry ball mill is more important. When dry grinding can be used for wettable materials, the materials must be analyzed and dried in advance to keep the moisture content below 1%.

3. Material particle size
Different from the crusher, the feed particle size has a great influence on the crushing capacity of the crusher, and is one of the main factors affecting the processing capacity of the crusher. Therefore, in the crushing stage, the energy consumption in the crushing stage is much less due to the different energy consumption in the crushing and crushing stages. It is very important to apply the principle of more crushing and less grinding in the crushing operation. Therefore, in the crushing stage with less energy consumption, the fine products should be crushed as much as possible to reduce the energy consumption in the crushing operation.

4. Crushing ability
The crusher is selected as the -1st element that can get the same size, even if the product needs to be crushed according to the required capacity, and then select the type, size and other crushing methods suitable for the mill.

5. Crushing method
The crushing methods are divided into wet type and dry type. Wet type crusher - limited to rotary crusher using steel balls or other media, as well as tower type crusher. There are also many types of dry type crusher. The operation before and after the crushing operation, the number of crushing sections, the selection of crushing process, etc.
