what is the powder making machine maybe you should know more about the definition of powder making machine.powder making machine is the equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Moh's hardness under six, the moisture under 5%.

there are some features of powder making machine 

such as

1.high efficiency

2.long lifecycle of spare parts

3.high safety and reliability

4.high fineness and flexible adjustment
5.environment-friendly

6.advanced intelligent speed control device.

if you want to use it clearly. 

then you should know its working principle.

powder making machine will mainly consist of main unit,classifier,powder collector,dust cleaner,induced draft fan,muffler,sound-proof room,crusher,bucket elevator,storage hopper,and vibrating feeder.
After crushed by hammer crusher,the large materials become small ones and are sent to storage hopper by elevator,and then evenly sent to the upper distribution plate of the turn plate by vibrating feeder and sloping feeding pipe.
when the powder making machine is at work. the main bearing and each dial are driven by electromotor of main eqiupment through reducer,and all the grinding rollers are rolling in the ring channels driving by dial through plunger.the materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed. crushed and grinded by the rollers.then the materials fall into multiple layers and to be crushed and ground continuously to powder.
