The press consists of:

Electrical system – controls the hydraulic system of the press. There are four electric motors: the first (30 kW) is used for driving the main hydraulic pumps; the second (1.1 kW) for driving the cooling hydraulic pump; the third (0.55 kW) for operating the fan of the oil cooling system; the fourth (1.5 kW) for driving the sawdust feed screw. The operation of the motors and hydraulic valves is controlled via contactors and intermediate semiconductor relays by a microprocessor with expansion modules. A liquid crystal display with buttons is installed for visualization and parameter adjustment.

Hydraulic system – with the help of pumps, high- and low-pressure and solenoid hydraulic valves, and hoses, operates the hydraulic cylinders. There are three hydraulic cylinders: the first (main) for sawdust compaction; the second (vertical) for initial compaction of sawdust; the third (shaping) for transferring the briquette shape. The system also includes an oil cooling circuit with a pump and air cooler. Oil filtration is ensured by the main high-performance filter, a cooler system filter, and a fine filtration unit.

Raw material feed is provided by a built-in feed hopper. Material in the hopper is periodically mixed to prevent bridging. The mixer is driven by a chain from the screw's motor gearbox. The screw cyclically feeds the raw material into the vertical cylinder column shaft. The hopper is equipped with two material level sensors (upper and lower). If the hopper is enlarged, the sensors can be repositioned as required.

Control – there are two modes: manual and automatic. All control equipment is housed in an electrical cabinet. Automatic control is the standard operational mode, without operator intervention. Manual control is intended for press adjustment, fault detection, or returning cylinders to their initial positions in case of malfunction. Operation is facilitated by a display located on the electrical cabinet door, allowing viewing and adjustment of set parameters, as well as monitoring press status and errors.
