Double Roller Potash Fertilizer Granulator Machine with High Granulation Rate and Adjustable Speed

The series of extrusion granulator drum type operates with a motor-driven system: belts and pulleys transmit power through a reduction gear to a drive shaft, synchronized by open passive gears to ensure both shafts rotate in the same working direction. Material is fed from the hopper, formed by roll pressure, and released as granules. The crushed material is then transferred to the sieve chamber via chain mechanism, where finished granules are separated and mixed back with new material for re-granulation.

• Shape of finished products: Oval, irregular, wheat shaped, etc., can also be customized according to customer requirements
• Material moisture requirement: Not more than 10%
• The rate of ball formation: 95%
• Output: 1-4t/h (can combine multiple granulators work together to increase output)
• Granule size: 3-8mm (popular market granule diameter: 2.8-4mm)

The motor-driven system utilizes pulleys and belts through a reduction gear to power two high-pressure rollers that operate in relative sliding mode. The SDZ extruder features two rollers that interact through a split gear mechanism.

The SDZ type two-roll extruder is directly driven by two dedicated output shaft gears to achieve the extrusion purpose. During production, raw material enters the hopper and is pressed into shape by high-pressure rollers.

After releasing, the material flow is crushed by shaped rollers in the lower portion. The breaking mechanism is dynamically formed by active pressing roller chain drive sprockets that drive crushing rollers in relative movement.

After crushing and screening, finished granules in the working chamber pass through the screen to the discharge port outside the machine.
