Double Roller Extrusion Compound Fertilizer Production Line Small Occupation Area

Type Double Roller Extrusion Fertilizer Production Line

The importance of powder granulating technology as one of the most important branches of powder particles processing treatment is increasingly clear with the demand of environment protection and improvement of automation of the production process. “Powder products will become granules” has become the necessary trend of powder-after-processing technology in the world.

dry roll press granulator adopts dry rolling technology to compress the powdery materials with moisture content ≤ 5% into pieces or tablets, then going through the processes of breaking into granules and screening to make the lump materials into granules that meet the requirements of application. Dry roll press granulator mainly depends on the manner of external pressure to force the material going through the gap between two relatively turning rollers to compress into laminar particles. During course of roller pressing, the real density of materials can increase 1.5~3 times thus reaching certain demands of granular strength.

Granulation drying: put the granulation into the dryer, and the moisture in the granules will be dried, so that the granulation strength is increased and is easier to store.

Granulation cooling: After drying, the granulation’s temperature is too high and the granulation is easy to lump. While after cooling, it is easy to bagging to save and transport.

Particle classification: the cooling particles that have been cooled will be graded: the unqualified particles will be crushed and regranulated, and the qualified products will be sift out.

Finished film: The qualified products are coated to increase the brightness and roundness of granules.
Packaging of finished product: The particles that have been wrapped the film are stored in the ventilated place.

major equipment in the Double Roller fertilizer Granulation Production Line

Batching machine:The main machine is composed of feeding system,weighing device, silo and conveyor belt. It has high automation and only needs manual feeding. It greatly saves time and production costs and meets thenational measurement standards.

Grinder:Cage crusher is suitable for the crushing of bulk materials in compound fertilizer production, but also widely used in chemical industry, building materials, mining and other industries. In the crushing process, the machine adopts high-strength bran-resistant cemented carbide chain plate with synchronous rotating speed. The inlet and outlet ports are designed reasonably, the crushed materials are uniform, the wall is not easy to stick, and it is easy to clean up.

Blender:High eficiency, high strring fficiency and less floor area. Helical blades are made of special alloy with high wear resistance. Smooth operation is driven by reducer, smooth rotation and low noise.Reasonable structure of single axle mixer feeding from top and discharging from bottom

Granulator:It is used for granulation to all kinds of organic matter after ermentation, break through the conventional organic prling before granulation. no need to dry and crush the raw materials before granulation. It can direct burdening to work out cylindrical grain, and save a lot of energy.

automatic packing and Mechanical gripper:For handling or alltizing box shaped materials, adjustable grabbing size, light aluminum alloy body, 304 stainless steel standard parts, swing hook base, one way translation clamping ensures stable and reliable grabbing.

All types of equipment are complete to meet the needs of customers. If you have special needs, ple ase contact our engineers in order to tailor the most suitable production line for you. Welcome customers to consult.
