Working Principle

VSG series ring roller mill uses the principle of impact, extrusion and grinding to crush materials. The structure of multiple layers and multiple crushing pairs makes this product have the following characteristics:


1> Large crushing ratio and high energy utilization rate. Calcium carbonate with a particle size of<10 mm is processed into fine powder of<10µm at one time, and the fine powder of - 2.5µm accounts for about 40%, with a large specific surface area. It has the advantages of high efficiency and low consumption of powder produced by high-speed impact crusher, and has the product fineness close to that of air mill.


2> The particle size of the product is adjustable and the fineness is good. It is the ideal equipment for the dry production of non-metallic ore fines. The main machine is equipped with a grading mechanism. The grading wheel has a unique structure and does not run coarse powder. The fineness of the product can be adjusted according to needs. It can produce fine powder with D97=5-8 µ m and coarse powder with D97=10-40µm.


3> Energy saving: It is a kind of fine grinding equipment with the lowest energy consumption at present. According to the data of Hefei Cement Research and Design Institute, the comprehensive power consumption (kwh/t) of several commonly used equipment for producing D97<10µm heavy calcium fine powder: Raymond mill 130, impact mill 260, vertical mill 175, dry sand mill 150, vibration mill 160, ball mill 160, and ring roller mill 95.
