Granite Three Roll Mill

Using a granite three roll mill can bring a lot of benefits to enterprises. First of all, the production cost is what many companies care about most. This machine is currently the cheapest and ideal equipment for grinding vegetable protein drinks. Of course, it can also be used to grind shoe polish. , daily chemicals, paints, coatings, pharmaceutical pastes, and other materials, through the three rollers of the granite three roller mill, at different speeds, to achieve the final grinding state.

The granite three roll mill produced by FRANLI mainly uses natural granite rollers and is made with traditional craftsmanship and the most advanced modern technology. This three roll mill has the characteristics of extremely high corrosion resistance, acid resistance, alkali resistance, rapid natural cooling, etc. During the work of the machine, there is no need to worry about the reaction with the material, and finally achieve the most ideal grinding fineness.

The composition of the granite three roll mill is the same as that of an ordinary three roll mill. It is mainly composed of a motor device, transmission device, roller shaft, frame, feeding and discharging device, adjustment device, cooling system, and other components. It mainly uses three rollers at different speeds to extrude and shear several surfaces against each other, to achieve the effect of dispersion.
Troubleshooting of rollers of a granite three roll mill
Because many companies are not familiar with the operation of granite three roll mills, it is easy to cause failures of the rollers of the three roll mills. The most common failure is the change of the parallelism of the rollers. The reason for the change of the roller is the wear and failure of the spring or slide of the roller. In addition, if the working surface of the inner turbine worm of the screw mechanism is worn, it will also cause problems with the parallelism of the grinding rollers. Once there is a problem with the parallelism on the rollers, the grinding efficiency will be reduced.

Problem 1: Internal wear of the screw
When the working surface of the worm inside the screw mechanism is worn out, there will be gaps on the surface of the meshing teeth of the turbine, increasing the lift angle of the screw, and the self-locking ability of the three roll mill will lose its function during the operation of the three roll mill. When the worm gear and worm are loose, the phenomenon that the two screw mechanisms cannot be synchronized during operation will occur, thereby accelerating the wear rate of the grinding roller.
Problem 2: Bolt spare cap problem
When the bolt cap of the three roll mill is missing, damaged, or loose, it will affect the adjustment device of the machine, resulting in the adjustment failure of the adjustment device and the failure of normal connection, so the grinding machine cannot execute the debugging instructions.
Problem 3: Spring Problem
When the grinder runs for a long time, there will be problems of reduced elasticity and fatigue wear. In the process of overhauling the three roll grinder, the grinding roller will be displaced, the spring cannot keep up with the overall running speed of the grinder, and the accuracy of the debugging work cannot be guaranteed.
Problem 4: Wear on the slides
When the slideway is worn, it will cause a certain resistance to the operation of the grinder, increase the frictional resistance during operation, and make it unable to move normally, which has the same principle as the above-mentioned spring failure. When the parallelism between the rollers of the three roll mills is significantly reduced, if no effective treatment measures are taken in time, the rollers on both sides will contact friction, increase the tooth pattern wear of the rollers, and finally reduce the three roll mill. The overall work efficiency of the machine.
