Description

one

The invention relates to the field of grinding rocks by special processing of dispersed materials, namely, devices such as a vibratory mill, and can be used in the chemical industry, in enrichment, in the production of ceramic and building materials.

A device for processing dispersed material is known, which comprises a vertical vibrating conveyor with a spiral chute with a bottom filled with grinding bodies filled with grinding bodies, with a lower loading and upper discharge ends 1. In it, the chute is divided along the length by partitions preventing the passage of the grinding bodies.

A disadvantage of the known device is low productivity due to the presence of partitions.

The purpose of the invention is to increase productivity.

The goal is achieved by the fact that, in a device containing a vertical vibrating conveyor with a spiral chute filled with grinding bodies with a bottom, lower loading and upper discharge ends, the chute is provided with an overflow chute connecting its ends. The current is equipped with a suction nozzle installed in its upper part, and the bottom

the discharge end is perforated and equipped with a discharge pipe mounted under it.

Such an embodiment of the device ensures continuous circulation of the charge at an increased rate.

The drawing shows a structural diagram of the proposed device.

10 The working member of the device is a vertical vibrotransporter 1 with a cylindrical body 2, carrying outside the spiral chute 3, filled with grinding bodies 4 and having a bottom 5,

15, the lower loading end 6 and the upper unloading end 7. The housing rests on the base 8 by springs 9 and carries below two unbalance vibrators 10, connected by flexible couplings 11c motors 20 mi 12.

The ends of the gutter are connected by a considerable inclination overflow chute 13, the longitudinal axis of which preferably has the shape of a segment of a helix with

25 more than the gutter, step. The current is equipped with a suction nozzle 14 installed in its upper part at the end of the upper end of the gutter. The bottom of this end is perforated, for example in

30 in the form of a sieve, net or grate 15, and is equipped with an outlet 16, mounted under this grate.

During operation of the device, a pair of vibration exciters 10, driven in a coordinated rotation by the engines 12, generates helical oscillations of the chute.

The grinding bodies are in the required amount in the chute and chute. The material to be processed is poured into the nozzle 14 (see direction arrows). The load circulates along the helix from the lower end 6 to the upper 7, as in a conventional vertical (spiral) vibrating conveyor, but at the same time the particles are subjected to impacts from the grinding bodies. In this case, the particles are crushed, the loose powder conglomerates are crushed and compacted, forming dense aggregates. The specific surface area of the powders and the bulk density increase significantly.

At the upper turn, the product is poured through the slots of the lattice 15 into the nozzle 16 for discharge, and the remaining mass of bodies and particles in the flow 13 is recycled, mixing with the material again loaded through the nozzle 14.

Due to the unhindered circulation of the load, the productivity of the device increases.
