Dry powder briquette press machine
Power: 45-90 Kw
Output: 2-15t/h
Application:
A hydraulic dry powder briquetting machine is used for making lime powder, ferrosilicon powder, chromium powder, refractory materials and other different fines which contain a low content of water or no water. This machine is widely used in the mining and metallurgy industry.
Working principle of dry powder briquette press machine
1. Feeding Part: The feeding part is mainly used to achieve ration feeding so as to ensure that the materials can be fed into the rollers uniformly. Specifically, the screw feeder, driven by electromagnetic speed adjustable motor, presses materials into the main feeding port compulsively by means of the belt pulley and worm reducer. Owing to constant torque, the motor can keep constant feeding pressure, ensuring stable briquette quality.
2. Drive Part: The main drive system of the briquetting machine is composed of a motor, triangle belt, reducer, exposed gear and rollers. The power generated by the electromagnetic speed-adjustable motor transmits to the driving shaft through a belt pulley, reducer and coupler, and the driving shaft will turn synchronously with the driven shaft by the exposed gear.
3. Briquette Molding Part: The core of the briquette molding part is the rollers. Through rollers, the raw materials can be compressed into briquettes of various shapes. In addition, the rollers feature overload protection, hence keeping sound quality.
Dry powder briquette press machine characteristics
1. Good effect material extrusion, high briquetting rate, and high briquette strength;
2. Good using effect roller surface, using-life is long;
3. Adopt double shafts of reducer structure, improve on roll precision,
4. Adopt full-steel reducer box, good sealing property
5. Using hard tooth surface gear, improve using performance and life;
6. The pre-pressure device uses an adjustable speed motor,
7. All wear pieces are welding wear alloy, improve using performance and the life;
8. The hydraulic station is independently placed, can adjust pressure and has a super pressure protection function.
