Abstract

The invention relates to the field of ancillary equipment and can be used for sorting grinding bodies (balls and cylinders) of pipe mills in the cement, metallurgical, chemical and other industrial sectors. The aim of the invention is to increase productivity, reduce energy costs. The installation has a frameless design and includes a receiving bunker-drive 1 with vibrators .4 installed on its side walls, inclined longitudinal sorting grids and receiving containers (containers) 16 and 17. The discharge opening of the storage bin 1 has the shape of a slit . In the center of the discharge slot of the bunker, an axle is mounted on the toggles and shock absorbers. On the axis 8, the upper bases of the sorting grids diverging in both directions are freely fixed, and their lower bases are mounted on folding support legs 13, which can vary in height and have shock absorbers. The sorting elements of the grids are made in the form of freely rotating tapered rollers. In order to ensure rigidity of the whole structure of the installation as a whole, its individual elements in the working state are fastened together by clamps 18. 2 Il. with s. sl 4 | C 00 CTL listened

: Figure 1 shows the installation, general view; figure 2 is the same, top view.

The installation for sorting grinding media includes a receiving storage bin 1, the discharge opening 2 of which has the shape of a slit. The upper frame of the bunker is provided with grippers 3 for I for its transportation and installation, vibrators 1 4 are mounted on the side walls, and on the lower ends of the end face -. by-

gratings 10 in both directions with the sorting elements 11 having the shape of the elongated freely rotating i 3 bearings of the tapered rolls. For

of material from the gratings, they are equipped with openings 12, and the lower bases of the gratings have folding posts 13, equipped with clamps 14 for changing their height and vibrating supports 15. Receptacles 16 and 17 for sorted materials and waste, containers with gratings by means of latches are placed under the gratings 18. Clamps are also installed between the sorting grids.

The device for sorting-grinding bodies is mounted and operates as follows.

Capacities are installed in a designated order at the site for sorting, two are in the center for receiving the waste and in both directions

the grippers 3, the receiving bin 1 are lowered along the dividing line between the containers 17 of the waste. In this case, the sorting grids 10 are diluted to the sides and with the help of folding struts 13 are installed above the containers 16 and 17, the required size of the gap between the lower end of the hopper 1 and the upper bases of the grids 9 is set depending on the largest size of the material being sorted (for example, ball) using t g 5 and selecting the optimum angle of inclination of the grids 10 by clamp 14, after which the whole system is fastened with latches 18.

For sorting the balls and tsilpebs, lattices 10 having different lengths and a set of sorting elements 11 are used, for this purpose they are made removable, with free installation (hanging) of the upper bases 9 on the axis 8.

After installation, adjustment and fixation of the installation with a lifting device (magnetic washer, grab, etc.), the batch of grinding bodies is loaded into the receiving bin 1. At the same time, the vibrators are turned on 4. The grinding bodies located in the lower part of the bunker are aggregated the force of gravity, the vibrations of the walls of the bunker and the shock absorbers 6, the suspensions of the axle 8, on which the upper bases of the grids 9 are fixed, begin through the slotted discharge opening 2 to be thrown out to the sorting grids 10 in both directions. The inclination of the grids is established close to or slightly above the value of the repose of the milling bodies, the latter begin to move relatively evenly along the conical sorting elements 11, and the support of the axle supports at the ends of the hinged support posts 13 contribute to this.

The first are sorted out of the battle, other small inclusions and dust that enter the tank 17, and then grinding bodies, increasing in size, sent to the respective tanks 16. This is ensured by the gradually increasing distance between the roll surfaces, In turn, their conical shape, the possibility of free turning of each roll relative to the others in co.
