Embodiment Construction

[0009] The present invention will be further described below in conjunction with drawings and embodiments.

[0010] refer to figure 1 , this embodiment includes a roller shaft 1, a grinding head 2, and a bearing seat 3. The grinding head 2 is fixedly connected to the roller shaft 1, and a twist plate 4 and a swing support sleeve 5 are also provided. The upper part of the swing support sleeve 5 passes through The screw is fixedly connected to the lower end of the bearing seat 3, a bearing 6 is arranged between the bearing seat 3 and the roller shaft 1, and the twist plate 4 is provided with a stop hole 7 for limiting the swing range of the grinding head 2.

[0011] When assembling with the mill turntable, the lower part of the swing support sleeve 5 is connected with the mill turntable (not shown in the figure) through a pin shaft, and the twist plate 4 is inserted into the turntable.

[0012] When working, driven by the turntable of the mill, the grinding head 2 revolves aro...

Abstract

The invention relates to a grinding roller of a roller grinder, comprising a roller shaft, a grinding head and a bearing seat, wherein the grinding head is fixedly connected with the roller shaft; the grinding roller is also provided with a knob plate and a swinging supporting sleeve; the upper part of the swinging supporting sleeve is fixedly connected with the lower end of the bearing seat; a bearing is arranged between the bearing seat and the roller shaft; and the knob plate is provided with a stopping hole for limiting the swinging amplitude of the grinding head. In the grinding roller of the roller grinder, the transmission torque force is large, the wearing capacity of parallel compensation lining plates is large, the automatic compensation performance is good, the medium operationis flexible, the crushing efficiency can be improved, the loss can be reduced, the service life can be prolonged, the operating noise is low and the maintenance is simple and convenient.

Description

technical field [0001] The invention relates to a pulverizer, in particular to a grinding roller of a roller mill. Background technique [0002] The grinding roller is the grinding medium and an important part of the grinding equipment; its structural performance is directly related to the efficiency and reliability of the overall mill. The grinding rollers of the existing roller mills have disadvantages such as unreasonable structure, low utilization rate of wear-resistant materials, uneven grinding force, short service life, high noise, and inconvenient replacement. Contents of the invention [0003] The purpose of the present invention is to overcome the defects existing in the grinding rollers of existing roller mills, and provide a roller mill with good automatic compensation performance, flexible operation, high crushing efficiency, low consumption, long service life, low operating noise and easy maintenance grinding roller. [0004] Technical scheme of the presen...
