Faqs:

What raw materials can the NPK High Pressure Roller Ball Press Machine process?

The machine can process aluminum chips, activated carbon, alumina, bauxite, caustic soda, charcoal, clay, coke breeze, coal, cryolite, chemical fertilizers, plastic powder, limestone, pigments, urea, and potassium fertilizers.
What are the material requirements for using this machine?

The particle size should be between 30 and 200 mesh, and hard metal objects must be avoided to prevent damage to the roller surface. A sufficient material supply is recommended, preferably using an adjustable speed screw feeder.
How does the NPK High Pressure Roller Ball Press Machine work?

The machine forces pre-pressed material into the central area of the rollers via a ball-pressing nozzle. The rollers apply compressive force, increasing pressure progressively until the material forms pellets, which are then discharged.
What are the output capacities of the different models?

Output varies by model, ranging from 180 kg/h for the DH240 to 13,000-16,000 kg/h for the DH1000. The exact output depends on material properties and process adjustments.
