Description

The known crusher is mainly for crushing coal, including a housing, in which the crushing elements and the drive are mounted.

However, the known crusher is ineffective in operation and does not provide the passage of the gaaritpy fraction of the feed material without additional crushing.

In order to improve the efficiency and ensure the passage of the overall fraction of the supplied material without additional crushing in the proposed crusher, the crushing elements are made in the form of tapered shafts with ribs arranged along a helical line, each tapered shaft being angled to the vertical axis of the crusher.

FIG. 1 - shows a general view of the list of crushers; in fig. 2 - the same plan view.

The crusher includes a housing 1, in which crushing elements 2 are installed, each of which is made in the form of a conical shaft with ribs arranged along a helical line, each shaft being installed at an angle to the vertical axis of the crusher. In the case are also mounted the upper 3 n 4 sawing 4 supporting sub-holders, conical N1 and crown 6.

Crusher works as follows. Gear 6, in which there is a bevel gear 5 in the internal engagement, is driven into the gearbox; The shafts rotate to the side, providing material and material supply with the ribs with the shaft down to the discharge end. When picking up edges from segments, the pieces of the angle also experience shock loading, which lowers their resistance to compression. The shafts rotate in one direction thanks to their uniform execution. Getting into the crusher, the conditional coal fraction passes along the walls of the hull and but the center of the crusher, and the large pieces of coal pass only through the center of the crusher, where they are crushed. At the moment of crushing a piece of si, reincarnated} 1, the perpendiculars of mercury of the main axis and upwards, parallel to axis 1, are estimated. This | 1loads the lower sub 1 and | 11 from shrtika. loads.
