Abstract

The invention relates to a grinding apparatus. The goal is to increase the self-cleaning of the working area. The grinding device comprises a support base 1 and a tray 2 with a chute 3 for accommodating the body 4, on whose surfaces cord charges 5 are placed. The chute is set obliquely in the discharge direction, while a push charge is mounted above the chute. Undermining of the blast hole and pusher charge produced simultaneously. 1 il.

Description

The invention relates to devices for grinding and can be applied in the construction and other industries.

The purpose of the invention is to increase the self-cleaning of the working area. 5

The drawing shows a device for the grinding of hollow volumetric bodies, General view.

The device comprises a support base 1 and a tray 2 with a groove 3 for accommodating the milled body 4, on the surfaces of which special cord charges are placed 5. The groove 3 of the tray 2 is made with an inclination in the neck 6 of the receiver 7 of the ground mass installed under the end part 8 of the tray 2. Above the upper part 9 of tray 2 has an additional pushing charge 10. 15

A device for grinding material operates as follows.

On the supporting base 1, the outflow 2 is installed using the lodgements so that one part 9 of the tray 2 is located above the other part 8 of the tray 2, i.e. with a slope in the neck 6 of the receiver 7 of ground mass, which is installed under the end part of 8 lots 2. A hollow spruce 4 types of shells made of composite with spiral cord charges 5 mounted on it and an additional pushing charge 10 placed above the upper part are installed in the chute 3 of the tray 9 tray 2.

The device is ready to work, undermine the cord 5 and pushing 10 charges at the same time 30, this allows you to grind the body and simultaneously feed the crushed mass through the inclined groove 3 of the tray 2 into the neck 6 of the receiver 7 of the crushed mass and clean the groove of the 3 trays by the particles of the particles moving in the dynamics. 2 and prepare it for re-work.

The operation of the device is experimentally checked when grinding shells from a composite of 0 400 mm, length 1200 mm Checking the results of grinding the material shows that the material is crushed into fractions with the sizes of pieces of 40-50 mm, the surface of the trough 3 of the tray 2 is released by a directed explosion of the pushing charge 10. The crushed mass is fed to the receiver 7 through the neck 6. Thus, the device gives a new positive effect, consisting in ensuring the efficiency of self-cleaning of the working area and the directed supply of ground mass to the receiver, which reduces the cost of preparing the device for the next grinding cycle.

The proposed device allows to accelerate the processing of industrial waste products from composites and rubber-like materials.

Claims (1)

Claim A device for grinding hollow volumetric bodies containing a support base and spirals of cord charges, characterized in that, in order to improve self-cleaning of the working area, the support base is equipped with a groove for accommodating the grinding body mounted obliquely in the discharge direction, while a pushing charge is mounted above the groove.
