Application scope of disc granulator

Disc granulator, also known as disc pelletizer, pan granulator, pan pelletizer, is suitable for granulating powdery materials, such as chemical fertilizer (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, compound fertilizer, etc.), limestone/gypsum, clinker, chemical powder, cement/lime kiln dust, coal ash, minerals and ores, pond tailings, municipal sewage sludge, electric arc furnace dust and other materials.

Application scope of disc granulator

Application scope of disc granulator

Disc granulator machines are widely used in chemical, petrochemical, pharmaceutical, food, building materials, mineral treatment, environmental protection, printing and dyeing, ceramics, rubber, plastics and other fields.

Why do you need granulation?

  • After granulating, the density of the material increases and its unit weight decreases, which is convenient for storage and shipment.
  • Impurities can be filtered out during material granulation.
  • Reduce dust hazards to people and the environment.
  • Improve the flow performance of powder mixture.
  • Material color becomes more uniform.
  • Reduce the possibility of material sticking and caking.
  • Prevent separation of material components.
  • Improve the quality of materials because of the addition of plasticizer, dispersing agent, grafting agent, etc. in granulation.
  • Improve material solubility.
  • Control the porosity and specific surface area of materials and improve its heat transfer, mass transfer, breathability, etc.

Outstanding advantages of Fote disc pelletizer

Fote disc pelletizer

Fote disc pelletizer

  1. 1 Novel structure, light weight, low height, flexible and convenient process layout.
  2. 2 Convenient angle of inclination adjustment of the pan granulator.
  3. 3 The disc granulator is composed of the disc body and disc section. The latter can be adjusted up and down along the former, and the end of the disc section is an edge flange to ensure that the granular material is not pulled or torn when it exits the disc.
  4. 4 After the welding and stress relief of the frame, its matching surface shall be processed and formed once on the boring miller to ensure higher assembly accuracy and smoother operation of the machine.
  5. 5 The scraper device, composed of unpowered combination scraper and corner cleaning scraper, can improve the granules forming effect after being used together with the optimized granules forming plate while clearing the bottom and edge.

Structure of Fote disc granulator

Fote disc granulator is composed of disc, motor, reducer, frame, base, rotating shaft, angle of inclination adjuster, scraper, etc.

Structure of Fote disc granulator

Structure of Fote disc granulator

  • The main body of the disc granulator includes a frame, an adjusting part, a granulating disc and other structures.
  • The main reducer is equipped with a pulley on the input shaft and a pinion on the output shaft.
  • The main motor is equipped with a pulley.
  • The supporting granulating disc device includes a spindle, two sets of roller bearings and two shaft blocks.

Structural characteristics of Fote disc granulator

  • The bottom of the pan is reinforced with multiple steel plates with high strength and rigidity.
  • The transmission gear, adopting high frequency quenching treatment, has a long service life.
  • The reducer and motor are driven by flexible belts, which makes the startup smooth and the impact force small.
  • The transmission system is equipped with the gap bridge device to reduce the direct impact of gear and reducer, improve the operation stability of the equipment and the service life of its main parts.
  • Adopt unique unpowered combined scraper device to reduce auxiliary power consumption.

Working principle of disc granulator

Step 1 Send fine-grained mixture to the feeding area of the disc through the belt conveyor.

Step 2 Spray a proper amount of water from the top of the disk with a sprinkler. Due to the cohesive force of water, the bulk material becomes the cue ball.

Step 3 The material is lifted up by the frictional force generated by the edge and bottom of the disk. When the material is brought to a certain height, it will roll down. The cue balls adhered with fine-grained materials continue to grow by sticking loose materials. The cue balls of different sizes roll up and down with the disc, constantly rubbing and compacting, and grow to the prescribed size.

Step 4 The small particles of different sizes are naturally graded. The small particles leave the discharge end, while the large particles are concentrated to the discharge end (the edge of the plate) and finally discharged through the edge of the plate.

Working characteristics of disc granulator

  • Disc granulator can not only make the material roll into the ball, but also produce a certain pressure on the ball.
  • The feed quantity required is equivalent to the number of fresh pellets discharged.
  • It can be automatically graded according to the size of the particles and the discharged green balls are qualified.

Operation cautions of disc pelletizer

  1. 1 Check whether the connection parts are firm and whether the bolts are loose before starting the machine.
  2. 2 Pay attention to the rotation direction of the disk when starting up.
  3. 3 The reducer must be filled with gear oil before it is used for the first time of production and it will be replaced every 4 months thereafter.
  4. 4 The bearing shall be lubricated once per shift. The lubricating oil type is No. 3 calcium base grease lubricating oil with the charge weight of 1/3-1/2 and it shall be replaced regularly.

How to improve the pelletizing rate of disc granulator?

1 Control the water content of granules.

Grab a handful of pelleted material from the disc granulator, if it can be hold into a ball and be loosened with a light touch of your finger, the granule will not be easy to block the screen surface and the yield of such granules will be high.

2 Strictly control the quality of powder.

It is strictly forbidden to have iron blocks, stones and wood blocks larger than 10 mm in raw material feeding and discharging.

3 Choose applicable nozzle of the pan granulator and adjust it appropriately.

The pan granulator generally adopts B-type spherical screw or B1-type screw nozzle. Under the same pressure, the nozzle with the small orifice spray small density droplet; the nozzle with the large orifice spray large density droplet.

4 Change scraper of the disc granulator.

The granule will be even in size and beautiful if the scraper is good. The material of the blade must be 16M. There should be no gap between two scrapers.

5 The main technical key to operate the disc pelletizer.

Carry out the technical training of the disc granulator to improve the technical quality and operation skills of the workers.

FAQ about disc granulator

What is generally the angle of inclination of the disc granulator?

The angle of inclination adjustment device is in the position of the support of the pan pelletizer, which can be adjusted according to the size of the required particles. The suggested angle of inclination is between 35° and 65°.

Does the material need to be dried after granulating with a disk granulator?

Yes. The material is added with a certain amount of water during the granulation process, which requires a dryer for drying to facilitate storage and transportation.
