Advantages of Roller Mills. 1. Produce more uniform, fewer fines, and oversized particles when it comes to product quality. 2. Generates less heat (0 – 3 0 C) unlike hammer mill that generates up to 10 0 C. 3. Less moisture loss. 4. Better work environment due to low machine noises level.
Unlike three high roller mills, the metal sheet will pass through only once. If you want to further reduce the sheet thickness, you need to take out the sheet from the machine and feed it again. In this rolling machine, the top and bottom rollers are the main rollers, whereas the middle rollers are just backup rollers ( Green Color in the picture).

Working principle of roller press Apr 29, 2020. Roller presses, also known as calenders, counter-rollers, rolling mills, squeezing mills, and roll press mills, are new energy-saving cement grinding equipment developed in the mid-1980s.
Automatic grinding gap adjustment. The grinding gap on our roller mills can be adjusted manually or, on some models, automatically. If you adjust the grinding gap automatically, the adjustment can be based on your recipe or on particle size. This enables you to produce a consistent and high quality of flour and semolina.
The roller mill can also produce a 30-80 mesh coarse powder by adding special equipment. The working principle of the roller mill is such that when the equipment is operated, the large material is coarsely crushed and then conveyed to the main grinding chamber of the roller mill for grinding.
When selecting a roller mill, work closely with the mill manufacturer to choose the optimal unit for your applica-tion. Ideally, you should observe roller mill tests of your material in the mill manufacturer's plant. The tests will help determine not only the best roll surface, roll speed ratio, and roll gap for your application, but the ...
The mill roller is driven by the electrical motor through an electrical motor and the material will be fed to the center of the disk from the feeding port via an air-locking feeder and meanwhile the hot-blast air will be blown into the mi I through the air inlet. Along with the rotation of the mi disk, the materials wi move to the edge
