A pass-through double-toothed roller crusher with side tooth plate installation and adjustment device and its adjustment method

Abstract

The invention relates to a pass-type double-geared roller crusher and adjusting method of a lateral tooth plate installation adjusting device, in particular to a pass-type double-geared roller crusher of an external-turning structure. According to the technical scheme, the upper portion of a lateral tooth plate is provided with a fixed lateral tooth plate (15), the lower portion of the lateral tooth plate is provided with a movable lateral tooth plate (2), the movable lateral tooth plate is close to a crushing roller (7), and the fixed lateral tooth plate stretches above the inclined direction of the movable lateral tooth plate away from the crushing roller; the movable lateral tooth plate is provided with a lateral tooth plate adjusting device (8); the front end of a movable lateral tooth plate body is provided with a plurality of teeth (16), the rear end of the movable lateral tooth plate body is provided with lead screw connection holes (17), and mounting striped holes (19) perpendicular to the lead screw connection holes are formed in a first matching inclined face (18). The pass-type double-geared roller crusher and adjusting method of the lateral tooth plate installation adjusting device is widely applied to the field of coal sieving and crushing, the distance of the lateral tooth plates relative to the crushing roller is changed by adjusting distance adjusting lead screws, the operation mode is simple and convenient, and efficiency is high; fixing of the lateral plate is achieved through matching of inclined faces between a pressing plate and the lateral tooth plates, the structure is safe and reliable, and practicability is extremely high.

Description

AI Technical Summary

Problems solved by technology

General-purpose, the two crushing rollers of the double-toothed roller crusher rotate inward to crush the material; however, in some special working conditions, the pass-through outward-turning crusher is required, for example: the crushing amount of the incoming material before crushing is the same as The proportion of the entire throughput is small (≤50%), and the space on the crushing site is relatively narrow, so it is not possible to add material classification equipment, and all materials must be crushed through the crusher; Crusher, its equipment model, installed power and supporting accessories need to be matched with the corresponding throughput, resulting in an increase in the cost of equipment selection, operation costs and spare parts supply; and there are some materials smaller than the particle size of the product in the When passing through the crusher, it is subjected to secondary crushing, resulting in an increase in the over-crushing of the product, and the block rate is seriously affected.
