The shape and size of the ball sleeve on the roll sheet can be selected according to the user’s needs. The shape of the pressure ball is pillow, semicircle, rod, pill, walnut, flat ball and square bar. At present, the shape of flat ball is adopted.
The double roll extruding granulator is a non dry room temperature granulator for one-time forming, which has the advantages of less investment, fast effect, good economic benefits, etc.
The complete set of equipment is compact, scientific and reasonable in layout, advanced in technology, energy saving and consumption reduction, no discharge of three wastes, stable in operation, reliable in operation, convenient in maintenance, and widely adaptable in raw materials. It is suitable for granulation of compound fertilizer, medicine, chemical industry, feed and other raw materials, with high granulation rate.
The double roll extruding granulator is the key equipment for compound fertilizer granulation. It has advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and is matched with corresponding equipment to form a small production line, which can form a certain capacity of continuous production, mechanized production, no drying, room temperature production, and rolling forming of products. The product quality meets the technical requirements of compound fertilizer, and it is a special compound fertilizer with high, medium and low concentrations The latest product for energy saving and consumption reduction in compound fertilizer industry.
The capsule is filled with particles, pigments, detergents, catalysts, strontium carbonate, chemical fertilizers, silica, inorganic salts, chlorides, cyanic acid, pesticides, oxides, etc., as well as industrial recovered dust materials such as cast iron dust, lead, zinc, aluminum dust, converter dust, filter dust, grinding powder, etc. The mechanical pressure is forced molding without adding wetting agent to ensure the purity of the product.
The production process of extrusion granulation is short, energy consumption is low, and output is large. Direct granulation of dry powder does not require subsequent drying procedures, which is more conducive to the connection and transformation of the production process of existing organic fertilizer equipment. The particle strength is high, and the stacking proportion is larger than other granulation methods. It is especially suitable for increasing the product accumulation ratio. The operation flexibility is large, the scope of application is wide, and the extrusion pressure is adjustable.
