Eccentric grinding roller integrated efficient grinding machine

Abstract

The invention discloses an eccentric grinding roller integrated efficient grinding machine. A main grinding machine comprises a base, a grinding ring, a main shaft, a grinding roller frame, an eccentric grinding roller imposed power assembly and a cover cylinder. The main shaft is arranged on the base center; the grinding roller frame is installed on the main shaft; a plurality of grinding roller assemblies are arranged on the grinding roller frame and in uniform circular distribution; the grinding ring is coaxially arranged in the base; the grinding roller frame is coaxially provided with a material distribution disc enabling the material to fall on a grinding zone uniformly; the main shaft is coaxially provide with a material fling platform, which is provided with a material fling device for flinging the material to the grinding zone; the base is coaxially equipped with the cover cylinder and an air return box; a classifier is installed on the cover cylinder; and the cover cylinder is provided with a feed chute for introducing the material into the material distribution disc. The invention adopts a zero suspension and eccentric thrust augmentation structure of the grinding roller assembly to reduce the height of the main machine, vibration, noise, and power consumption; at the same time, repair and replacement of the grinding roller and grinding ring do not need to remove the classifier, and are very convenient and time-saving.

Description

(1) Technical field: [0001] The invention relates to powder processing equipment, in particular to an eccentric roller-integrated high-efficiency mill. (2) Background technology: [0002] Pulverizers are widely used in the mineral powder industry, among which pendulum Raymond mills and ultra-fine ring roller mills are the main ones. [0003] The general structure of the host of the traditional pendulum Raymond mill is as follows: the upper end of the main shaft is equipped with a fixed roller frame (or called plum blossom frame), and a plurality of roller frames are evenly hung on the fixed roller frame through a hinge device, which are parallel to the central axis and form a circle. The distributed grinding roller assembly, during the rotation of the fixed roller frame, the grinding roller assembly relies on the centrifugal force to keep each grinding roller in contact with the grinding ring, and crush each other to crush the material. [0004] The grinding roller assembly...

AI Technical Summary

Problems solved by technology

[0006] During the rolling process, if the large particle material cannot be crushed at one time, when the grinding roller bounces to avoid it, it will impact the grinding ring and cause vibration, which will limit the speed of the main machine and affect the efficiency and output of the mill.
