How to grind diatomaceous earth by ultra fine grinding machine

Ultra fine powder grinding mill is is the new type mining equipment for making micro powders, fine powders,which is widely applied in the industries of metallurgy, mining, chemistry, cement, construction, refractory materials, ceramics, and so on. It mainly consist of main unit, classifier, dust cleaner, powder collector, blower, muffler, hammer crusher (can be replaced by jaw crusher), bucket elevator, sound-proof room, storage hopper, vibrating feeder and so on.


Features and advantages of Ultra fine powder grinding machine for :
● High Efficiency
Under the same finished final size and the same motor power, the capacity of Fine roller mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.
● Long lifecycle of spare parts
The ring and roller are forged by special material with high utilization. Under the same grinding material and finish special size, the lifecycle of spare parts is about one year, which is 2-3 times longer than impact mill or turbo mill. Furthermore, the lifetime can reach 2-5 years for grinding calcite carbonate.
● High safety and reliability
As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components.
● High fineness, flexible adjustment
The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm.
●Environment-friendly
The application of pulse bag filter and muffler greatly alleviates dust pollution and noise.
●Advanced intelligent speed control device
Convenient adjusting, more uniform particle size.

How ultra fine grinding machine operate?
1. Start up Vertical mill
1) Turn on main switch
2) Start air compressor, adjust air pressure of oil-water filter to 0.6-0.7 Pa.
3) Turn on bag filter pulse controller, adjust the pulse frequency to one spray every 4-5 seconds, adjust pulse width to 0.5-0.8 seconds (pulse controller was set before delivery)
4) Switch on bucket elevator
5) Start up crusher
6) Feed materials to the crusher till enough crushed materials are sent to the hopper, and then start the classifier.
