Micro Powder Grinding Mill For 1500 Mesh Powder With Output Of 3t/H
In order to guarantee the micro powder grinding mill can work smoothly and stablely, the following work need to be done:
Please check the following items before starting the mill:
1.Please ensure the voltage should not be less than 360V.
2.Please wipe out all the liters, and all the bolts and nuts are all connected tightly.
3.Make sure the belt tightness is proper, and move the belt wheel by hand, and mill wheel can rotate flexibly.
4. Ensure the valve handle in the blower air-in pipe is on the “close” position.
5.Make sure the tightness of the elevator chain is ok.
6. Regular lubrication should be done according to the lubrication table, and ensure there is no grease or oil leakage.
7.feeding size into to the mill should be less than 10mm
8. Make sure the motor rotation direction is correct.(a)the mill motor rotation direction should make the mill shaft go around counterclockwisely. (b) the classifier motor should make the vane wheel turn around clockwisely. (c) the blower motor should make the blower wheel go around counterclockwisely.
9.Any metallic material should not be in the raw material. The users had better install the iron eliminator by themselves.
Structure of Micro Powder Grinding Mill:
The micro powder mill has the folllowing components: crusher, elevator, hopper, feeder, classifier, mill, collector, blower and electric control cabinet. And delivery and installation of the whole micro powder grinding mill system is simple and easy to be completed. As the micro powder grinding mill has been tested in the factory, so the micro powder grinding mill can run as soon as the installation is completely. Generally speaking, one engieer from factory can do installation and test running work. Micro powder grinding mill has the advantages of higher output, low investment and simple grinding technique. The mechanical and chemical reaction in the process of grinding is also good to improve powder activity.
Working Principle of Micro Powder Grinding Mill:
A)The raw material will be lifted into the hopper by elevator after being crushed by crusher.
B)The raw material will go to the mill by the belt conveyor.
C)The material will be ground into powder between the roller and ring.
D)The qualified powder will go into the pulse collector through the classifier. And the unqualified powder will fall down to the mill for being reground.
E) The powder will be collected in the collector and the clean air will go out through the fan.
The motor makes the mill shaft and roller table go around by the V-belt. The roller will rotate and revolve against the ring, which will make the material into powder from the top level to the bottom level. Classifier includes motor, coupling, shaft, vane wheel and housing. The motor controls the classifier wheel rotation speed. The faster the rotation speed, the finer the powder and vice versa. The motor controls the classifier wheel rotation speed. The faster the rotation speed, the finer the powder and vice versa. The Pipe System include pulse collector, powder-in pipe, extra air pipe, air-return valve pipe and muffler.
Special Features of Calcite Ultrafine Grinding Mill:
1. Constant temperature control system is adopted and the whole design is also improved, so various additives can be put into the mill to improved the application range of powder.
2. High quality casting technology to prolonger the working life of roller and ring.
3. Special deisgn for easy maintenance and spare parts replacement
4. Micro powder grinding mill can be connected the packing machine seamlessly, which can increase packing efficiency and lower labor costs.
5.Perfect contact surface between rollers and ring: The compatible surface contact between rollers and rings can increase crushing force and grinding area and improve crushing efficiency. And this will be useful for producing ultrafine calcite powder.
6. For longer working life and prevent powder from being contaminated, the hardness of rollers and rings are increased.
7. Pulse-jet Collector: 99.99% of the ultrafine powder can be collected, which is also environment-friendly.
8. Vibration absorption and Compact Structure, high safety and reliability
9. Inverter for motor speed control, which can lower power consumption and adjust rotation speed of the mill and classifier to produce different fineness.
