Product Details of double roller granulator

Double roller granulator machine is suitable for producing high, medium and low concentrations of compound fertilizer and organic fertilizer. The final granules produced by fertilizer roller press granulator are of oblate shape. Roller fertilizer granulator adopts no drying normal temperature technology, having low investment, fast returns and good economic benefit. Integrating granulation, forming and screening, double roller granulator has the features of nice appearance, easy operation, and low energy consumption.double roller press granulator is a new-designed fertilizer roller compaction granulation device developed & researched by ourselves. Materials are granulated at room temperature, and there is no drying process, more energy-saving and cost-reducing. With the characteristics of small investment, large profits, and quick results, the double roller compactor granulator will bring investors bigger economic returns. It can be used in compound fertilizer production with high, medium and low concentration.

Working Process of Roller Granulator Machine

The double roller fertilizer granulator machine is the representative of extrusion granulator. Dry materials are compressed into hard & dense blocks at a pressure, which is the Extruding Process. Block materials are crushed, screened and granulated later, which is the Granulating Process. The functions of extrusion are to squeeze the air between particles out, and to make the distance between particles near enough to give rise to interaction forces. The particle hardness of roller compaction granulation granules is formed mainly due to attraction between the molecules. Our double roller press machine is continuous extruding granulation of positive-displacement.

Advantages of Roller Press Granulator

1.No drying process, normal temperature granulating, one-step forming.

2. Saving energy and cost, no waste water or gas emission.

3. Compact structure, easy and stable operation, easy maintenance.

4. Press rollers adopt new metal which is resistant to corrosion, wear and impact.

5. The press rollers can be designed to make different shapes and sizes of materials.

6.The machine adopts no drying technology, granulated at room temperature and molded at one time. The advantages of DZJ roller granulator is less investment, quick results and good economic returns.

7.Structurally, the machine adopts granulation, molding and screening as one, which has the advantages of beautiful appearance, simple operation and low energy consumption.

8. The main parts, such as rollers, are made of a new type of metal with corrosion resistance, wear resistance and impact resistance. The DZJ-II machine not only has the above characteristics, but also the frame part has also been upgraded. The bearing frame is selected as the whole component with high quality anti-corrosion casting. With more stable performance, it can greatly improve the service life of the rolling bearing and shaft.

9. For the transmission part, the dual input transfer mode are applied, which not only improves the input power ratio, but also ensures the lubrication and sealing performance of the transmission gear. The machine has the advantages of compact structure, good stability, good sealing, low noise, convenient operation and maintenance

What Kind Of Materials Can You Process With Double Roller Granulator?

this double roller granulator can be widely used in many businesses. It can granulate pellets with a number of different kinds of raw materials. Here are some of the applications for you to refer to.

1.Compound fertilizer granulation. The extrusion granulation was initially applied to create potassium chloride pellets, so you can use the extruder pellet machine to produce compound fertilizers and BB fertilizers. You can pelletize any NPK fertilizer materials and dried organic materials with it, especially for the granulation of tombarthite, potash fertilizer, ammonium bicarbonate, etc. It also can produce granules of different concentrations and usages, just change the formula of the mixed materials before putting them into the machines.

2.Solid chemicals granulation. Some of the solid chemicals can be granulated by our pellet extruder, the working principle is similar to the compound fertilizer granulation, such as antioxidant, cyanuric acid, oxides, etc.

3.Pharmaceutical granulation. Since Shunxin fertilizer double roller extrusion granulation machine works based on physical extrusion, you can also use it to produce some of the medical tablets, and those little granules used to fill in the capsules.

4.Daily commodity. Some chemical products which is used in daily life can also be granulated by our machine. Like pigments, detergents, some cosmetics, salt granules, hops, and so on.

5.Industrial dust recovery materials. Those powders and dusts left during processes can be granulated and used as materials again, such as coal dusts, metallurgy leftover powders, etc.
