The no dry extrusion granulation process for the roll extrusion granulator
has a wide range of uses in powder processing granules, and its characteristics are that the material can be directly processed without damaging the material or heating. It can be used for the processing of organic and inorganic fertilizer granules, and also for the processing of feed granules.
By using the dry-free extrusion granulation process, no waste water or exhaust gas is discharged during the production process, and the environment is not polluted. The extrusion granulation process
is short, easy to operate, and it is easy to realize production automation control and improve production efficiency. There is no special requirement for the nature and particle size distribution of the raw materials, so the source of the raw materials is relatively broad.
Five process stages of organic fertilizer and inorganic fertilizer on roll extrusion granulation production process
1. Add qualified raw materials to the fertilizer mixer
according to the ratio of mixing requirements.
2. Delivered to the disc feeder to remove the metallic substances in the material during the transportation process.
3. The material in the disc feeder enters the Double Roller Press Granulator
uniformly, the material is forced to pass between the two pressure rollers and is extruded into a thin sheet, and the sheet is broken into pieces by a coarse crusher under the pressure roller. After screening. The material on the screen continues to be broken and sieved.
4. The semi-finished product is delivered to the finished screening machine
. The fine particles after screening are returned directly to the disc feeder. The large particles are pulverized by a pulverizer and returned to the disc feeder.
5. The qualified products after screening are transported to the automatic packaging scale for weighing, packaging and storage.
Advantages of Roller Press Granulator Production Line
1.The roller press granulator is without drying process, room temperature granulation, a molding , less investment, quick effect, good economic returns.
2. Compound fertilizer on roller extruding and granulating machine power of small reliable operation, no waste discharge, stable operation, convenient maintenance, process layout is reasonable, advanced technology, low production cost.
3. The roll press granulator machine can be used for extensive applicability of the raw materials, the granulation of compound fertilizer, medicine, chemical fertilizer, feed, coal. metallurgy and other raw materials, can produce various concentrations and types (including organic fertilizer, inorganic fertilizer, bio-organic fertilizer, magnetic fertilizer etc.)compound fertilizer.
4. The roller press granulator machine , especially raw earth carbonate ammonium sulfate, compound fertilizer, to fill the gap, the leading domestic level, is the national environment protection technology promotion project.
