The press consists of:

Electrical system – controls the hydraulic system of the press. There are four electric motors: the first, 30 kW, is intended for driving the main hydraulic pumps; the second, 1.1 kW, is for driving the cooling hydraulic pump; the third, 0.55 kW, is for driving the fan of the oil cooling system; the fourth, 1.5 kW, is for driving the sawdust feed auger. The motors and hydraulic valves are operated via contactors and intermediate semiconductor relays, which are controlled by a microprocessor system with expansion modules. For visualization and parameter adjustment, an LCD screen with push buttons is installed.

Hydraulic system – using pumps, high- and low-pressure hoses, and solenoid hydraulic valves to operate the hydraulic cylinders. There are three hydraulic cylinders: the first – the main cylinder for compacting sawdust; the second – vertical cylinder for pre-compaction of sawdust; the third – forming cylinder, responsible for shifting the briquette shape. The system is also equipped with an oil cooling system with a pump and air cooler. Oil filtration is performed by the main high-performance filter, the cooling system filter, and a fine purification filter.

Raw material feed is performed via a feed hopper integrated into the press. The material entering the hopper is intermittently mixed to prevent bridging; the mixer is driven by a chain linked to the feed auger gearmotor. The auger cyclically feeds material into the shaft of the vertical cylinder column. The hopper has two material level sensors: lower and upper. If the hopper is enlarged, the sensors can be repositioned as needed.

Control – two modes provided: manual and automatic. All control equipment is installed in an electrical cabinet. Automatic operation is the standard working mode of the press, with no operator intervention required. Manual control is intended for press adjustment, troubleshooting, or returning cylinders to their initial position in case of emergency. Operation is facilitated by a display mounted on the electrical cabinet door, showing the input parameters, which can be adjusted as needed. The display also shows press status and error messages.
