Vertical roller mill is good at SBM powder making machine, according to the SBM’s physical property, the working principle can be introduced as follow:

When the vertical roller mill is working, the grinding roll, under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure ratio is 1.2 times of common roller mill given an identical condition, and its output may increase 10% to 20%; Please note that when the grinding roller and grinding ring reach a certain degree of abrasion, please adjust the length of high pressure spring to keep the constant grinding pressure between grinding roller and grinding ring, so as to ensure a stable output and fineness.

The vertical roller mill’s working principle is same as high pressure grinding mill, to be honest, the high pressure grinding mill is also one of the typical vertical roller mills; however, the price of SBM vertical roller mill is really cheaper that other grinding mill, we usually can get a vertical roller mill between $30000-$50000, and if you also need other grinding machines, such as: stone crusher, powder packing machines, the price will more expensive.
