Abstract

The invention relates to cone crushers used in the production of non-metallic building materials. The aim of the invention is to reduce material overheating and increase productivity. To achieve the goal, the fixed cone 1 is made with channels 4 and 7 located along its height in staggered order with loading 5 and unloading 6 windows, while inside the fixed surface of the lining 2 of the fixed cone there are internal pockets 8 connected to loading windows 5 of channel 4 and 7. 1 z. p. f-ly, 2 ill. and f 1 (L

Description

The invention relates to crushing equipment and can be applied in the production of bulk materials, mainly non-metallic building materials.

The purpose of the invention is to reduce overgrinding and staking performance.

FIG. 1 shows a cone crusher, a longitudinal section; FIG. 2 is view A of FIG. one.

The crusher includes a stationary cone 1 with lining 2, consisting of individual rings - at ow 3 by alignment 2 and differences at the joint of ow 3, crush the piece into smaller and partially smallest, which, partially falling into pocket 8, unload through the holes 6 are formed in the middle, and in the lower part (calibrated 15 pieces fall into the chambers of the middle zone) of the fixed cone 1 and lining 2 channels 4 with loading 5 and discharge 6 windows are filled.

Above these channels, additional channels 7 are also filled with loading and unloading windows identical to windows 5 and 6o, respectively.

Channels 4 and 7 are arranged in a checkerboard pattern and, through the loading windows 5, are interfaced with internal pockets 8, made on the working

The use of the invention allows to reduce the overgrinding of the material by increasing the throughput during the unloading of the crusher and to increase the output of crushed commodity fractions, which gives an economic effect of up to 5.0 thousand rubles.

the invention

the surfaces of each liner are 9 lining and located above the lower ZO formula, which forms a unloading i with a movable crushing cone 10. The cone crusher containing the slot 11. The movable cone 10 has the crushing chamber with the main cone 12 forming the movable crusher 35 with the flue-loading slot 2 the chamber 13 of the large crusher 35, the cone and the outer fixed cone, the cylindrical part 14 wear-resistant lining having

Along the perimeter of the outer side 18 of the lower cone 1 a receiving device 19 is installed for the material. C Lining 2 has a relief work surface in the form of protrusions 20 and valleys 21, pockets 8 are located in depressions 21 of lining 2, and loading windows 6 are on protrusions 20 of lining 2 forming the bottom of pockets 8, the last 50, measures that are comparable to the size discharge gap 11.

During the operation of the crusher, the pieces of rock for crushing enter the canals, and on the working surface of the lining there are inner pockets located above the loading windows of the channels and conjugated with
