What is Roll Extrusion Compound Fertilizer Granulator?

The Roll Extrusion Compound Fertilizer Granulator machine is a dryless granulation machine and a relatively advanced drying-free granulation equipment. It has the advantages of advanced technology, reasonable design, compact structure, novelty and utility, low energy consumption. It can support the corresponding equipment, forming a small production line to achieve a certain capacity of continuous, mechanized production.

Work Principle Of Roll Extrusion Compound Fertilizer Granulator

The Roll Extrusion Compound Fertilizer Granulator machine belong to the extrusion slip model, it adopts dry rolling technology to compress the powdery materials into particles. Dry roll press granulator mainly depends on the manner of external pressure to force the materials going through the gap between two relatively turning rollers to compress into particles. During the rolling process, the real particle density can be increased by 1.5~3 times to meet the requirement of certain particle strength. The granulation rate of this machine is high, widely used in the granulation of compound fertilizer, medicine, chemical industry, feed, coal, metallurgy and other raw materials, and can produce a variety of concentrations, a variety of types (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.) compound fertilizer.

Advantage of Extrusion Compound Fertilizer Granulator Machine

1. Without any additives, dry powders are granulated directly.

2. Granular strength can be adjusted by adjusting the pressure of roller, control strength of final products.

3. Cycle operations to achieve continuous production.

4. Materials are force to compress molding by mechanical pressure, without any additives, the product’s purity is guaranteed.

5. Dry powders are granulated directly without follow-up drying process, the existing production process is easy to convergence & transformation.

6. Granular strength is high, compared with other granulating methods, the improvement soft bulk density are significant,especially for the occasion where increase the proportion of product accumulation.

7. A wide range of raw materials can be used for granulating, granular strength can be freely adjusted according to different materials.

8. Compact structure, easy maintenance, simple operation, short process, low energy consumption, high efficiency, low failure rate.

9. Control environmental pollution, reduce waste and powder packaging costs, and improve product transport capacity.

10. Major transmission components use high quality alloy material. Stainless steel, titanium, chromium and other surface alloys which greatly improved wear resistance, corrosion resistance, high temperature and pressure capabilities, so that this machine has long service life.
