Milling process

The grinding production line is suitable for the grinding and processing of mineral materials such as metallurgy, building materials, chemicals, mining, etc. It can be used for feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite, manganese ore, phosphorus Ore, iron oxide red, quartz sand, cement clinker, activated carbon, clay, coal gangue, gypsum, silicon carbide, refractory materials, etc. Non-flammable and explosive mineral product powder with Mohs hardness below 8 and humidity less than 6% Processing.

The whole machine structure is composed of main machine (Raymond mill), analysis machine, pipeline device, blower, jaw crusher, bucket elevator, silo, electromagnetic vibrating feeder, power distribution cabinet, etc. The working process of the machine: After the bulk material is crushed to the required size by the jaw crusher, the material is sent to the silo by the elevator, and then the material is uniformly and quantitatively continuously sent to the main machine grinding chamber by the vibrating feeder for grinding. The ground powder is taken away by the airflow of the fan, and classified by the analyzer. The powder that meets the fineness enters the cyclone collector with the airflow, is separated and collected, and then discharged through the powder outlet tube to become the finished powder.

The air flow is then sucked into the blower by the return air pipe at the upper end of the large cyclone collector. The entire air flow system of this machine is closed and circulating, and it flows in a state of positive and negative pressure. There is a certain water content in the material to be ground in the mill. The heat generated during grinding causes the gas in the mill to evaporate and change the air flow. At the same time, because the joints of the pipes of the whole machine are not tightly sealed, the outside air is sucked in, which increases the circulating air flow. Therefore, the balance of air flow is achieved by adjusting the residual air pipe between the fan and the main engine, and the excess gas is introduced into the bag filter to collect the fine powder brought in by the residual gas, and the residual gas is purified and discharged.
