The press granulator GR-1 is the main part of the equipment. Designed for obtaining pellets from biomass by pressing it with pressing rollers through the radial holes of the ring matrix.

The principle of operation of the press granulator GR-1 is as follows:

The product is fed evenly into the mixer. The main task of which is continuous mixing and moistening of raw materials. As well as forced feeding of the mixture into the pressing chamber of the granulator.

Structurally, the mixer is a horizontal cylinder with inlet and outlet nozzles. Inside which a paddle mixer rotates in two bearings, which is driven by a V-belt transmission from an electric motor.

The prepared mixture enters the pressing chamber between a rotating ring matrix. This matrix rotates, with a horizontal axis of rotation and two rollers rotating inside it on fixed axes. The matrix is ​​driven by an electric motor. At the same time, due to friction, the pressing rollers rotate. The torque from the electric motor shaft through the two-stage V-belt drive rotates the faceplate shaft with the matrix.

At the same time, the pressing rollers rotate from the contact with the raw material located on the inner surface of the matrix. The pressing chamber pulls the raw material between the rotating matrix and the pressing rollers, pushing it into the matrix’s radial holes (dillers), where high pressure forms granules. The granules squeezed out of the die matrix break off. The broken pellets from the cover with a presser are sent further along the technological process.

Safety shear fingers are provided in the design. In the case of overloading or jamming of the matrix fixed on the faceplate with rollers (when a foreign body hits between them). The increased force cuts off the safety fingers, and the normally stationary axis together with the flange rotates.

Specialists rigidly fasten the press granulator (with an anchor or other rigid connection) in a certain place in the room to the base (floor of the room, concrete base, metal structures, etc.).
