Micro powder grinding mill
I. Brief introduction.
YFM series grinding mill is a new-type grinding mill developed by our company for decades, combining rolling, impacting and grinding to one. It is an ideal ultrafine ground calcium carbonate grinding mill for deeply processing non-metallic minerals which hardness less than Moh's 5, such as calcium carbonate, barite, talc, gypsum, calcite, limestone, calcium oxide, bentonite, dolomite etc. The finished particle size can reach 325-3000 mesh(3.5-50 microns).
II. Working principle.
When operating, the raw material is fed continuously from the input system into pulverizing chamber, the material will be fully pulverized after impacting, pulverizing, grinding and concussion by the grinding wheel; then the pulverized material is conveyed to the classifying chamber to be classified according to their particle size. The qualified particle will go into cyclone separator through grading wheel, and then go out to be product. A little unseparated powder will be collected by high-effective dust collector then putout to be qualified product. During this period, the whole system is working under negative pressure, the air which is cleaned by dust remover will go out through high-pressure air-introduced machine, and no dust will out to the air.
Note: The above parameters are tested by calcite for reference only,there might be slight differences regarding to different materials.
1. Enviroment friendly.
Total line machine is closed system ,the bag filters has passed CE&ISO certificate , our bag filter is pulse off-line type, which has many boxes working one by one , you can control the working time lag, when next one working, this worked one can have time to clean itself. By the way, we suggest clients install crushing line outside of factory , because crushing part surely have dust out .
2. Long lifecycle of wearing parts:
Our wearing parts made by wear-resisting alloy steel or high chrome steel, which is designed by our technical department. Each spares has its ID NO. with this ID NO., you can check its production record and testing report at any time.The normal wearing parts include grinding rings, grinding rollers, grinding plate and shaft pins , normally for grinding calcium carbonate, 10 hours /day, 30days/month, they can work 18-24 months.
3.Advanced electric controlling system.
Total production line controlled by PLC (Siemens) brand with KTP touch screen ,which can make one key start and stop . So you no need worry about starting and stopping steps mistakes.
Also, once the hopper has no material for feeding main unit, then main unit will stop automaticly.
Once installation finished, you can store at least four setting data inside PLC soft , for example, you can set 325 mesh, 800 mesh, 1250 mesh and 2500 mesh , once you changing producing between these sizes , you can only set one key to transfer the producing size , which has made the operation steps very easy to operate .
