tri roller mill



Tri-roller mill is suitable for grinding and dispersing ointment or high viscosity materials with high requirement of fineness. It achieves required grinding effect by the friction and crashing among the three horizontal rollers rotating at different speeds. The clearance between the rollers is adjusted manually. It is equipped with emergency brake button to prevent equipment damage caused by foreign matter dropped into. The roller is a casting of special hard alloy and ceramic materials are optional.

Working Principal:

The equipment consists of three rollers fixed on the frame and driveb directly by the motor. The rotation direction between rollers is generally different, the former roller rotates forward, rear roller rotates backward. The speed of former roller is quick, while speed of rear roller is slow. The mid roller is fixed, former and rear rollers are mounted on the slide with spring device. Adjust the distance between three rollers by adjusting the hand wheel. The material, charged from space between rear roller and middle roller, are squeezed by the rollers to obtain smaller particle size. Then the material are rolled out by the fast roll (Roll rotates at high speed). The scrapper at the end of the fast roller separate materials from the roller and fall into the collection barrels. Since it produces a lot of heat in the grinding process, the center of each roller is hollow. Input water for cooling to ensure finished products with good quality.
