Abstract

The invention relates to devices for grinding and drying materials of increased moisture and stickiness. The purpose of the invention is to increase productivity and reliability. The device comprises a housing 1, a rotor 6 with bilami 7, a shaft 3 of a separator, a loading nozzle 2. Armor 8 8 are attached to the housing 1 and the wall 12 of the shaft 3 by means of longitudinal ribs 13-16. Through windows 17 and 18, coolant is supplied to the conditioned channels. (L fu2 t

Description

Hydropushers 21 are fixed to housing 1. And wall 12 of the shaft 3, the rods of which pass through the holes in the armored lining 8 - 11. The rods of the hydropushers 21 are hollow and have nozzle holes on the free end. When hydropushers 21 are turned on, working fluid is ejected through the forcing holes of the rods.

The invention relates to a device for grinding and drying material of increased moisture content and adhesion, and can be used in construction, mining and other industrial areas.

The aim of the invention is to increase productivity and reliability.

Figure 1 shows the proposed device, the cut; figure 2 - section aa in figure 1; on fig.Z - hydropusher

incision.

The device for grinding and grinding of the material comprises a housing 1, a loading nozzle 2, a separator shaft 3, a bump stop 4, a viewing hatch 5, a rotor 6 with billes 7, 8–10 armored fires, KOTOpbife is attached to the housing 1, and 11 fastened to the attacked wall 12 of the shaft 3 by means of longitudinal ribs 13-16 of stiffness forming channels for the passage of coolant coming from the furnace through windows 17 and 18. The channels have an exit to the inside of the mill via sp; spruce 19 and 20. In addition, on housing 1 and on the attacked wall 12 of the shaft 3, the hydropushers 21 are mounted, the rods 22 of which are They are fired through the holes in the armor fires 8-11 and have a hole 23 passing along the axis of the rod and ending with the nozzle holes 24, with the rods 22 in the non-working position being flush with the inner surface of the armor lining 8-11, and inside the mill at 25 - 80 mm.

The device works as follows.

which smaey1; The internal surface of the armored anti-bulge equipment 8-11 before the operation of the device. During the operation of the device, the material is laid on the armored 8 .- 11, the lubricant layer due to the heating by the coolant boils, forming a crust of adhered material, which is discharged by the hydraulic tappet 21. 3 sludge.

Before starting the mill, 1-2 strokes of the rods of the hydropushers 21 are performed. At the same time, the inner surfaces of the armored 8-11 are lubricated with a layer of hydraulic fluid of the pushers 21. Hot gases and raw materials enter the body 1 through the charging nozzle 2, which is caught by the rotating rotor 6 of the rotor 6. and It is thrown onto the armored 8 - 1 1. From blows with bilami 7 and from an 8–11 armored fire, the raw materials are crushed, and the finished powder is carried away in gases to the 3 se5 parator shaft. Fly away from beat 7, the material hits an armored 8 - 10 and partially sticks to them, forming a layer of material over time. At the same time, through the windows 17 and 18, hot gases from the firebox are pumped into the canals under the 8-1.0 armored fires, which heat up the 8–10 armored fires. 11 The armored fire 11 does not require additional heating due to the hot gases passing between it and the wall 12 , as the material dried during grinding sticks less. Due to the heat transfer, the lubricating layer boils and the layer of sticking on the material is braced to form a crust. The hydropushers 21, which are intermittently switched off, detach from the armored vehicle 11 by the rods 22 an adhering mass, which collapses under pieces of the rotor 7. Simultaneously with the working and idling strokes of the stem 22, the working fluid ejected through the nozzle holes 24 undermines the adhesion mass, and again smears the inner surfaces of the armored lugs 8-11 with the working fluid of the hydropushers 21.

In the hours of thioes. For clay in the production of ceramic bricks, petroleum waste is used as a lubricating fluid, which, when it is baked, replaces burnable additives introduced into the mixture (coal, sawdust, etc.)

The invention improves the performance and reliability of the device.
