GK9920,GK990 Series superfine pulverizer is mainly used in metallurgy, chemical industry, construction, pharmaceuticals, ceramics, electronics, military and other industries. For deep processing non-flammable, non-explosive mineral materials whose Mohs hardness and humidity is under 6 and 6% respectively, such as Talc, feldspar, zeolite, Calcite, barite, pyrophyllite, dolomite, Phosphate rock, wollastonite, coal, kaolin, bentonite, bauxite, titanium dioxide, ferrosilicon, gypsum, mica, quartz, corundum, zircon sand, emery and so on.
It absorbs the superiorities of raymond mill, ultrafine roller mill, vertical mill, grinding material with impacting, crushing, milling. So that the material is fully and completely crushed. It is featured with high fineness, low power consuming , high efficiency.
2. Technical Advantages:
1. Unique grinding way: The rollers are hanged parallelly with the ring inside main frame.In the running process,roller assemblies stay still ,and ring rotates along with the tray.Materials are thrown around ring wall by centrifugal force and are propelled by shovel blade to the space between rollers and the ring.Meanwhile,the rollers revolve around roller shaft.The rotation is driven by the material which is between the ring and roller.Consequently ,material will be grinded by pre-tightening force from high pressure spring.
2.Lower Iron Content & Keep Material Color: There is no touch between roller and ring, so the iron content will be lower and material color will be keep better.
3. Lower Maintenance Cost: The maintenance cost for the main wearing parts ,i.e. roller, ring, shovel knife, is lower than Raymond mill.
4. Strong Grinding Force: The grinding force for each roller assembly , which comes from the spring force, can achieve 4000KG.
5.Super-fine Product: The fineness can be 600-1500 meshes.
6. Simple operation & Easy Maintenance.
