limestone grinding millIntroduce

The MW series ring roller micro powder mill is a new type of high-efficiency and low-cost ultra-fine powder feeding equipment developed by combining more than three years of mill production experience and drawing on the advantages of domestic and foreign mill manufacturers. After multiple thorough investigations, research, and experiments, it is a crystallization of advanced technology and the best product in the field of ultra-fine powder feeding to replace traditional grinding machines internationally

limestone grinding millAdvantage

 1. In the case of the same fineness

it’s less investment, less cost and shorter recycling cycle than jet mill.

2.Low wear and tear of vulnerable parts

Roller and ring are made of high-quality wear-resistant materials,forging technology, and long service life.

3.Safe and reliable operation in the grinding cavit

No rolling bearing and no screws inthe grinding cavity to avoid theproblem that the screws are easy toloose and damage the machine

4.More stable transmission

Adopting a gearbox transmission device, it is more stable and efficient than traditional belt transmission

5.Accurate granularity control

A new high-efficiency cage type powder selection machine with variable frequency control, convenient particle size adjustment, precise cutting particle size, and a one-time finished product fineness of D97≤5μm

6.Environmental protection

High efficiency pulse dust collector is adopted, with high dust collection efficiency and no dust. The well is equipped with a fire extinguisher and a partition room, which effectively reduces noise and meets the latest national environmental protection standards

limestone grinding millWorking Principle

When the ring roller mill works, the motor drives the main machine to rotate, and the grinding disc starts to rotate. The ring roll rotates along the edge of the mill. ! The material is evenly distributed to the grinding disc by the feeding device, and is compacted and ground into powder under the friction and extrusion of the grinding disc and the ring roller         In the grinding process, the fan sends hot air through the pipe into the grinding, drying and grinding together with the material. The hot air can also cool the main engine and effectively control the temperature of the equipment. After grinding the material and the air flow into the separator, after powder classification, the material reaching the required particle size is blown out, the coarse particle flow back again, forming a closed cycle.
