SU1240447A1 - Method of processing material in a crusher - Google Patents

Description

. The invention relates to the crushing and grinding of porous materials and materials, and specifically to methods of processing the material in the crusher and can be used in the mining industry, in the production of construction and special materials mainly in the processing of frozen and similar rocks. .

one . The purpose of the invention is to increase the processing efficiency of frozen, sticking rocks.

 The drawing shows an example of the implementation of the proposed method in relation to the jaw crusher with one movable cheek complex swing

The method is carried out as follows.

The material is crushed in the chamber .1 between the fixed grinding cheek 2 with holes (perforation) 3 and the movable cheek 4 with the drive of a known construction in the composition of the eccentric shaft 5, the pulley flywheel 6, the rods moving to the right of the holes

Porn plate 7 and their friend elements. The pieces of material in the chamber are destroyed as a result of cyclical crushing at each turn of the cheek 4 forward Chvdevo, and when it moves to the right, they are lowered. The holes 3 are made elongated, and their edges 8 prevent the pieces of especially frozen rock from slipping upwards when crushed. In doing so, the holes may gradually clog. They are cleaned by the rods 9, which enter the holes and are mounted, for example, on a common rocker arm 10 with the hinge 11 of its oscillations. Drive; these swings can serve as a crank mechanism in the composition of the shield - Compiled by Y. Khechanov

In this form of implementation, the implementation of the method is. Tom,

and the beam mechanism each of

rods 9 per cycle is moved to

hole 3. right after cheek

4, when it departs, and when it reaches the end of the hole, it returns to the left to its original position, and so on.

The principal feature of kinematics is that the rods,

clearing away, do not go beyond them, i.e. They do not enter the chamber zone, which prevents the impact of crushing forces on them, and at the same time the vibrations of the rods 9 and cheek 4 are syn-phase. .

Example. With a cheek frequency of 240 col / min, the rocker 10 swings with the same level of 240 col / min. those. synchronous and in-phase. When re

fine particles, clay, etc .; the right dead point of the rods is separated from the crushing surface of the cheek 2 by 3-5 mm.

Without cleaning the -holes, their upper edges cannot perform the functions of nor cross corrugations, which provide conditions for the effective capture and non-slip of pieces of rock, especially frostbite.

Cyclical cleaning of the holes with rods moving in. openings without leaving them and in-phase moving cheek, increases the processing efficiency of metered, adherent and similar materials.
