No water/binder/dry Hydraulic/physical press Low water/power/space consumption High strength/density Briquette machine

Briquette machine operating principle:

The briquette machine adopts the couple roller. Between the rollers, there is certain gap. Using double output shaft reduction machine, makes the couple roller in phase and run face to face. One group of roller axle seat is fixed and another group of roller axle seat is slipped. With the support of the pressure of hydraulic cylinder, they are close to each other and the hydraulic system can has the action of compensation and protection. In the surface of the roller, the hole (arc trough) of many shapes and same size are arrayed. According to the different compression rate of the materials, choose the trough of one roller aiming at the trough of another roller, or peak to trough. Two rollers is arranged in horizon. The powder material on itself weight is compulsorily feed into the gap between two rollers over the rollers continuously and equally. When the material enters into the gripping area, it is gripped by the roller. With the continuous turning or the roller, the occupied space of the material is less and less and gradually compressed and reaches the max value of the formation pressure. Then, the pressure gradually reduces. The flakes due to its elasticity and self weight breaks off the arc trough.

i).dim (L×W×H) : 3660×2450×2700mm

j).wt: about 22t

k).briquette output:8-10t/h

l). briquette shape: oval/oblate/almond

Briquette machine component:

1) Ration feeding device: Composed of raw material silo and star type charger with fixed amount transportation, 1.5/2.2kw power, frequency conversion speed adjustment.

2) Screw feeder: Composed of charger with 11kw frequency conversion speed adjusting motor, taper helix, agitator knife, taper charger with observation window and feeding bucket. This is to further finish degasification and pre-compress the powder.

3) Compactor: Composed of fixed axle seat and slipped axle seat, two alloy steel rollers, two hydraulic cylinder and pump, double output reduction machine, Type GIICL drum jugged shaft coupling and 90kw electromotor set. 

4) Electrical control cabinet: Composed of electrical control box, frequency conversion speed adjusting controller, ammeter, voltmeter, instruction light, button, voltage conversion switch, etc.

5) Vibrating screen: (one set) the grinded material from the grinding and granulator is screened into the grain by this machine and recycled powder.

6) Bucket hoisting machine: Equipped based on the request.
