The press consists of:

Electrical system: Controls the hydraulic system of the press. Equipped with four electric motors: the first (30 kW) drives the main hydraulic pumps, the second (1.1 kW) operates the cooling hydraulic pump, the third (0.55 kW) drives the fan for the oil cooling system, and the fourth (1.5 kW) drives the sawdust feed auger. Motor and hydraulic valve operation is managed via contactors and intermediate solid-state relays, controlled by a microprocessor with expansion modules. An LCD touch screen is provided for visualization and parameter adjustments.

Hydraulic system: Using pumps, high and low-pressure hydraulic and solenoid valves, and hoses, the system manages the operation of the hydraulic cylinders. There are three hydraulic cylinders: the first – main, for sawdust compaction; the second – vertical, for initial sawdust densification; the third – forming, for pushing briquettes into shape. Additionally, there is an oil cooling system with a pump and air cooler. Oil filtration is performed by a main high-capacity filter, a cooling system filter, and a fine cleaning filter.

Material feeding is performed via an integrated loading hopper. The raw material, once inside the hopper, is intermittently mixed to prevent bridging. The mixer is driven by a chain from the auger gearmotor. The auger cyclically feeds material into the vertical press cylinder column. 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-mode control is provided – manual and automatic. All control equipment is installed in the electric cabinet. Automatic control is the normal working mode, not requiring operator intervention. Manual mode is used for press adjustment, fault detection, cylinder reset to initial positions, or in emergency situations. Operation is facilitated by a display located on the electric cabinet door, showing entered parameters, which can be changed as needed, as well as press status and error notifications.
