Grinding roller mechanism device

Abstract

A grinding roller mechanism has a rotor with a central axle hole, a roller pressing unit with a pressure regulator and a connecting rod linked between said pressure regulator and grinding roller, and a regulating and limiting screw for regulating the gap between grinding roller and grinding disc.

Description

technical field [0001] The invention relates to a grinding roller of a roller mill, in particular to a grinding roller mechanism device. Background technique [0002] At present, people use a Raymond mill to crush objects. The grinding roller mechanism of the Raymond mill has a conjugate body, and a vertical pendulum roller is hinged at the end of the conjugate body. When crushing materials, the main shaft rotates at a high speed, driving the conjugate body. The main body rotates, and the pendulum roller presses the material on the millstone for rolling and crushing under the action of centrifugal force. There is only the effect of centrifugal force, there is no gap between the pendulum roller and the millstone, and there is direct contact between the metals, resulting in a large consumption of metal materials. Pressing powder grinding force is the centrifugal force produced when the main shaft rotates, and there is a defect that the grinding force is insufficient; China Pat...

[0002] At present, people use a Raymond mill to crush objects. The grinding roller mechanism of the Raymond mill has a conjugate body, and a vertical pendulum roller is hinged at the end of the conjugate body. When crushing materials, the main shaft rotates at a high speed, driving the conjugate body. The main body rotates, and the pendulum roller presses the material on the millstone for rolling and crushing under the action of centrifugal force. There is only the effect of centrifugal force, there is no gap between the pendulum roller and the millstone, and there is direct contact between the metals, resulting in a large consumption of metal materials. Pressing powder grinding force is the centrifugal force produced when the main shaft rotates, and there is a defect that the grinding force is insufficient; China Patent Office has announced a kind of vertical mill (announcement date: on August 18th, 1993, announcement number CN2140261Y), the The mill borrows the grinding roller mechanism of Raymond Mill, adopts multi-layer grinding roller group, and implements multi-stage crushing on materials, but its grinding force is still the centrifugal force generated when the main shaft rotates, and there is still the defect of insufficient grinding force
