Working principle:

PFA is added from the top of the equipment, and enters the counter roller through degassing and spiral prepressing. PFA is plastically deformed and compressed into sheet form under the action of great pressing force of the counter roller. The flake PFA is then crushed, granulated, and screened to obtain a PFA granular product. The size of the extrusion pressure can be adjusted by the pressure of the hydraulic cylinder according to the needs of the granulation operation. Different pressure settings can get different strength of the finished PFA particles.

Equipment features:

1. Without any additives, PFA direct granulation.

　　2.PFA GranulesThe intensity can be adjusted. By adjusting the pressure of the roller, the strength of the finished product is controlled.

3. Cycle operation to achieve continuous production.

The finished product output is high, and the single output can reach more than 1000 kg/h. (Bulk density 1.5 × 103kg/m3)

Main configuration:

1. Forced feeder (main hopper)

2. Pair rolling unit

3. Rack platform

4. Crushing whole granulator

5. grading screen (according to user needs selection)

6. Bucket elevator (optional according to user needs)

7. Electrical control cabinet

Product advantages:

PFA by mechanical pressure forced compression molding, do not add any wetting agent, product purity is guaranteed.

Short process flow, low energy consumption, less auxiliary equipment and personnel.;

PFA is directly granulated without a subsequent drying process.

PFA particles have high strength, and the increase in bulk specific gravity is more significant than other granulation methods.

The operating elasticity is large, the adaptation range is wide, and the strength of PFA particles can be adjusted by hydraulic pressure.

System closed cycle operation, to achieve continuous production.

PFA roller granulator is a utility model powder dry granulation equipment developed by absorbing foreign advanced powder granulation technology. The machine has reasonable design, compact structure, simple process and convenient operation. The powder raw materials can be directly processed into uniform PFA particles of 0.5-5mm by this equipment without any additives, which greatly improves the bulk density of PFA, thus reducing consumption, controlling environmental pollution, reducing packaging costs and improving the operating environment of workers.

The powdery PFA is added into the main flake rolling hopper quantitatively and evenly to keep a constant material level in the main flake rolling hopper, and then the powder is pre-compressed by the longitudinal cone screw in the main flake rolling hopper and transported to the PFA of the arc slot of the two press rollers to bite into the groove and be forced to compress instantly. The pressure of PFA after being compressed and formed is gradually reduced under the action of its elastic force and gravity, it falls off from the tank, enters the crushing and whole particle system, and then sieves and classifies according to the user's particle size requirements to obtain uniform PFA granular products that meet the quality requirements. The sieved powder is returned to the hopper for recycling. (In briquette, the granular PFA is compacted between two counter-rotating rollers, and the briquette may use a binder.)

Suitable for PFA particles, zinc oxide, lead oxide, calcium chloride, calcium phosphate, bleaching powder, fine cryolite, antioxidant, white carbon black, benzene, dimethyl sulfate, potassium chloride, potassium chloride, Russian red potassium nitrate, potassium ammonium chloride, ammonia, phosphate, ammonia, phosphate, NPK compound fertilizer imported from Russia, potassium sulfate, phosphate rock powder, sulfate, calcium perovskite, humic acid, etc.
