The invention has refined to the processing of materials by pressure, namely, to briquette presses, and can be used for briquetting in the preparation of the charge for the blast-furnace and steel-making production.

The purpose of the invention is to improve the quality of briquetting.

Fig, 1 shows a roll-flax exact briquette press, a general view; FIG. 2 shows a pressing roll with a balance and a counterweight.

A vapkovo-ribbon briquette press contains a matrix 1, a pressing 2 and a thrust 3 rolls dispenser 4, a flexible endless belt 5, an envelope matrix 1, a tension 6 and guides 7, 8 and 9 rolls, a mechanism 10 for adjusting the wrap angle of the matrix 1 of a flexible endless belt 5 and functional connection 11 between mechanism 10 and metering actuator 4 The pressing roller 2 is provided with an unbalance 12 and a counterweight 13 so that their common center of gravity (CG) is located between the opposite unbalance 12 of the roller 2 and the counterweight 13. The pressing roll 2 is barrel-mounted and assembled ram with rolling opportunity along forming matrix 1. Unbalance 12 is driven from electric motor 14 through petal clutch 15 Press roller 2 is driven through coupling 16 and V-belt transmission from electric motor (not shown) about forming a wrap angle of flexible 1 matrix tape 5 on its section 17 between the direction of the 7 and the pressing 2 rollers additionally installed pressure roller 18. Between the thrust roller 3 .and the inner surface of the matrix 1 additionally have a flexible endless belt 1 with supporting and shaping its conductive elements 20, such as rollers. The belt 19 is tensioned by the stretch roller 21 o. The flexible belts 5 and 19 are made in the form of Mobius 22 belts. To improve the supply of charge to the zone between the belt 5 and the matrix 1, a vibrator 23 is installed. On the inner surface of the matrix 1, an ejector 24 is installed, in the region of Gutter 25 is adjoined to matrix 1, through which briquettes 26 are fed to an assembly conveyor 27. Pressing

roll 2 is mounted on frame 28 with shock absorbers 29.

Roll-tape-briquette press works as follows

The pressed material (charge) is fed into the zone between the belt 5 and the matrix 1 rotating from an individual drive using, for example, a vibrating distributor 4 and a vibrating compactor 23. The pressing roller 2, through the belt 5, presses the mixture into the conical holes of the matrix 1, making a rotational motion relative to own axis and rocking relative to the center of the body (CG), located between the opposite debalance 1-2 end of the roll 2 and the counterweight 13.

For this purpose, the pressing roll 2 is barrel-shaped and mounted on the frame 28 with shock absorbers. 29 De-balance 12 swings the roll 2 by means of a drive from the electric motor 14 through the spade clutch 15. The rotational movement of the roll 2 is carried out from an individual drive through the clutch 16.

At the moment of loading, pressing in and up to unloading, the charge, and then the briquettes are in the conical holes of the matrix 1 between flexible endless belts 5 and 19, made in the form of Mobius 22 surfaces. The pressing of the briquettes (maximum pressure on the charge) occurs between the pressing 2 and resistant 3 rolls. Then, the briquettes in the conical holes of the matrix 1, due to the endless belts 5 and 19, remain for a period of relaxation in a compressed state before they approach the ejector 24, which pushes the briquettes 26 from the holes of the matrix 1 into the grooves 25, and then they arrive at the assembly conveyor 27 and are sent to the consumer

In order to promptly change the angle of girth of the matrix 1 by flexible tape 5, a pressure roller 18 with an individual pressure device is additionally installed between its direction 7 and the pressing 2 rollers, which makes it possible to obtain briquettes of a given density from various materials and with different physicomechanical properties , for example- humidity measures etc. With a sharp increase in the number of feeds supplied by the dispenser 4 by the press circuit of the preamplifier, the wrap angle adjustment mechanism 10 is a matrix 1 1 flexible tape 5, which, via the functional link 11, changes the operation mode of the vibrating dispenser 4 in the direction of reducing the amount of charge.

The use of a roll-belt briquette press improves the quality of briquettes by equalizing the pressure along the length of the generator matrix, displacing the air from the pressing zone, improving the conditions for loading the press and providing volume compression and a necessary period of relaxation.
