Bentonite grinder is an important equipment for high-fine powder processing of bentonite. This equipment has the advantages of high grinding efficiency, good sealing, and low energy consumption in operation, which can create a more considerable economy and society for the production of users benefit.
The overall structure design of the bentonite mill is simple and compact, mainly composed of the main shaft, coupling, grinding roller, grinding ring, blade, blade holder, fineness analyzer, blower and other structures. The simple structure design makes the equipment easier to operate.
1. High degree of grinding automation: adopting a new design, based on the principle of high yield and convenience, updating the design, and streamlining the structure, greatly improving the automation level of the bentonite grinding machine, which can realize computer control and real-time control of the grinding status, which can be realized in the workshop Unmanned operation.
2. The finished product has high whiteness, precision and cohesiveness: the grinding fineness is uniform, and the finished bentonite has higher whiteness, precision and cohesiveness. It has higher application value and can better meet the needs of high-grade materials in various fields.
3. Good sealing, no finished product pollution and dust leakage: the bentonite mill is always in a negative pressure sealed state during the grinding process, using a strong powder tube, with strong pressure resistance, no dust leakage and finished product pollution during the grinding process Phenomenon, equipped with advanced dust collection device to ensure that the workshop is clean and pollution-free.
4. Large processing capacity at one time: the feed size is ≤15-≤30mm, and the production capacity is 2-120t, which can meet the production requirements of most users. The power of the main motor is from 132kw to 7.5kw, which can ensure the efficient operation of the equipment.
Working principle of bentonite mill
After the bentonite mill starts to work, the grinding roller rotates around the main shaft and rolls against the grinding ring under the action of high-pressure spring and centrifugal force. The rolling pressure is twice higher than that of the Raymond powder machine under the same power condition, so the output is large. To improve.
When the bentonite to be ground enters the grinding cavity, it is shoveled by a spatula and sent between the grinding roller and the grinding ring for rolling. The crushed bentonite powder is brought into the analyzer with the circulating air of the blower. Flowing into the cyclone powder collector is the finished product, and the large particles fall back to regrind. The circulating air returns to the blower to repeat the above process, and the remaining air enters the bag filter for purification.
When the grinding roller and grinding ring reach a certain degree of wear, adjust the length of the high-pressure spring to maintain a constant grinding pressure between the grinding roller and the grinding ring, so as to ensure stable output and fineness.
