The press consists of:

Electrical system — controls the hydraulic press system. Equipped with four electric motors: the first (30 kW) is for driving the main hydraulic pumps; the second (1.1 kW) is for the cooling pump; the third (0.55 kW) is for the fan of the oil cooling system; the fourth (1.5 kW) is for driving the sawdust feeding 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 provided for visualization and parameter adjustment.

Hydraulic system — controls the operation of hydraulic cylinders using pumps, high and low-pressure lines, solenoid hydraulic valves, and hoses. There are three hydraulic cylinders: the first (main), designed for pressing sawdust; the second (vertical), for the preliminary compaction of sawdust; the third (forming), for transferring briquettes to the mold. An oil cooling system with pump and air cooler is also installed. Oil filtration is provided by the main high-performance filter, a cooling system filter, and a fine filter.

Feeding of raw material is provided via a feed hopper integrated in the press. The raw material entering the hopper is intermittently mixed to prevent bridging. The agitator is driven via a chain from the screw drive motor-reducer. The screw cyclically feeds raw material into the vertical cylinder shaft. The hopper is equipped with two level sensors (lower and upper). If the hopper is enlarged, the sensors can be relocated as needed.

Control — dual operation: manual and automatic. All control equipment is installed in the electrical cabinet. Automatic control is the standard operating mode of the press without operator intervention. Manual control is intended for press setup, fault detection, cylinder reset, or in case of emergency. Operation is simplified by the display located on the cabinet door, which allows the user to view and modify parameters and monitor the condition and errors of the press.
