Work principle: With principle of impact, press and mill to crush material, the gap between milling ring and axis is wide, when milling ring frame revolutes with main axis, it is thrown to milling circle by centrifugal force, and press inside millingring tightly rotating with pin. The material will be impacted, crushed as passing though gap between milling ring and milling circle. The crushed material is brought to the classifying chamber to be classified. The certificate products are collected while the coarse are returned to the crushing chamber for further crush. There are one or two milling rings. As the double milling rings works, the material in the gap between milling ring and milling circle will be crushed again.So the customer can get their wanted product. Characteristics: Low investment, high efficiency compared to large equipment, it can save 60% of the investment. High classifying precisions: adopting special inner classifying device, the structure of classifying wheel is unique and performance is robust with out coarse contamination.. The milling part is made from special wear-resisting alloy with long service life. Safe and reliable work, simple installation, wholly casting structure for mainframe pedestal and good quake reduction. High driving efficiency, ,main axis is employed reducer to drive, with high performance and low energy consumption. The efficiency is more than 96%. Meet environmental protection requirement and the dust discharging density below 40mg/m3 Application: It is arranged to pulverize the material with hardness below 5 such as calcium carbonate, talcum powder, bauxite, kaolin, diatomaceous earth, detonate, grapphite, limestone, calcite, marble stone, barite, gypsum, pottery clay, chalk, dolomite, mica, illite, leaf agalmatolite, vermiculite, sepiolite, concave good stone, rectories, alum stone, fluorspar, tablet ore, potassium ore, pumice, iron oxide red, iron oxide green, aluminum oxide, dye, papermaking, burning inhibitor, building materials, pesticide. Technical parameter:

Model	Power? kw	Product size um	Capacity kg/h	Weight? T
HM-580	81	10-45	300-1500	9.6
HM-930	170	5-45	1100-3000	21.5
Remarks	Crushing material is calcite on the above parameter,feeding size <20mm
	Because of different material in different areas, the parameter is only a reference.
