26 or 28 Rollers Calcite and Limestone Ultrafine Grinding Mill for 400-2500 Mesh Powder with 97% Sieving Rate
Stucture of 26 or 28 Rollers Calcite and Limestone Ultrafine Grinding Mill:
26 or 28 rollers calcite and limestone ultrafine grinding mill has the folllowing components: crusher, elevator, hopper, feeder, classifier, grinding mill, pulse-jet collector, blower and electric control cabinet.
The most important part of the 26 or 28 rollers calcite and limestone ultrafine grinding mill is the grinding housing, which influence the grinding efficiency and powder fineness. Perfect contact between rollers and ring in the grinding housing is most important. Our calcite and limestone ultrafine grinding mill arc or curved surface increases their effective working surface and improves the crushing efficiency. The rollers and rings contact surface and shapes should be consistent and tightly fit, which is good to the production of fine powder.
Working Principle of 26 or 28 Rollers Calcite and Limestone Ultrafine Grinding Mill:
26 or 28 rollers calcite and limestone ultrafine grinding mill can grind raw materials by impact, extrusion and grinding. There is a gap between the grinding roller and rings. When the rollers revolves round the main shaft, the grinding roller will move towards the ring by centrifugal force. Through the gap between the grinding roller and the grinding ring, the material will crushed by the impact, extrusion and grinding by the grinding roller.
The material is ground by the first layer of the grinding roller and grinding ring, then will fall into the second layer of the grinding roller be ground again as per the same principle, followed by the third and fourth layers. After the material is ground by the grinding roller in the last layer, it will fall onto the turntable under gravity and stretched out to the lowermost milling equipment, and brought to the interlayer between the inner and outer walls of the cylinder by negative pressure airstream, and once again rise to the top air classification system for separation. Qualified fine powder will pass through the classifier and enter into the pulse dust collector; coarse materials will be directly knocked to the grinding table and resettle in the pulverizing room for pulverization. The turntable is distributed in multiple layers. Thus, the material is sufficiently crushed to reach the desired fineness.
Customers from many countries had sourced this kind of 26 or 28 rollers calcite and limestone ultrafine grinding mill to grind calcite, limestone calcium carbonate, talc, barite and etc. According to the mill performance in customers’ factory, our customers think our ultrafine grinding mill is much much better than other mill.
