Dolomite mills, namely ultra-fine mills, micro-powder mills, etc., are one of the current industrial mills. With the development of modern industry, traditional Raymond mill equipment is far from meeting the development of modern industry. The fineness requirements for various heavy calcium carbonates are high, reaching the micron level, and the powder requirements of some products reach the nanometer level. Ordinary Raymond mill equipment can only crush the material to a few hundred microns. On the basis of the Raymond mill, it has been transformed by technological innovation, and the fineness can reach several microns, and the common one is about 5 microns.

The ultra-fine pulverizer produced by Shanghai Clirik Machinery Co., Ltd. is mainly composed of a host, an analyzer, a blower, a finished cyclone separator, a pipeline device, and a motor. It also includes powder conveyors, powder feeding and metering equipment, powder collection equipment, and powder storage and packaging equipment.
Among them, the powder conveying equipment is in the processing of ultrafine mills. The raw material needs powder conveying equipment from the storage point to the crushing grinder to the classifier to the next level of classifier arrow to the storage bin. And there are many types of powder conveying equipment. The ultra-fine mill also includes feeding equipment. The feeding machine is installed at the discharge port of the storage bin to uniformly discharge the materials, and then feed them to the next equipment. It can be said that the feeder is an indispensable equipment in all the supporting equipment of the ultrafine mill.
The first is the particle size of the raw materials. The particle size of the raw material cannot exceed the size required by the index of the ultra-fine mill. If it exceeds, the output particle size of the material will be too coarse, because the production capacity of the ultra-fine mill is limited and cannot exceed its required particle size The size of the indicator. And when other conditions are kept unchanged, the coarser the raw material, the coarser the particle size of the powder produced, and the finer the raw material, the finer the particle size of the powder produced. The hardness of the raw material is also limited. The hardness of the raw material also affects the processing quality of the ultrafine mill. When other conditions remain unchanged, when the hardness of the raw material is too large, the output particle size of the powder will be relatively large and the quality will be reduced.
In addition, in the production process, if the amount of raw materials put in is too much, the material will stay in the ultra-fine mill for too little time. Too little residence time will definitely lead to insufficient grinding of the material, so that the powder will be produced. If the particle size is too coarse, the production quality will be reduced. Therefore, it is necessary to control the amount of material in the production process. According to the production performance and model size of the ultrafine mill, the amount cannot be too much or less.
