The process flow is short, the energy consumption is low, the dry powder output is large, and the granulation is directly performed without the need for subsequent drying processes, which is more conducive to the connection and transformation of the existing production processes. The pellet strength is high, and the increase in bulk specific gravity is more significant than other pelletizing methods. Especially suitable for increasing the stacking ratio of products. The counter-roll granulator has great operation flexibility, wide application range and adjustable extrusion force.
When I first entered the counter-roll granulator industry, I started to learn from the downstream of equipment processing. In the early stage, I was limited to inorganic fertilizers and compound fertilizer raw materials. I learned nitrogen fertilizer and potash fertilizer. In an exchange with my predecessors, I learned that the original counter-roll granulator Not only in the field of fertilizers, but also in other fields.
The counter-roll granulator is suitable for granulation of various raw materials such as medicine, chemical industry, feed, coal, metallurgy and so on. Widely used in fertilizers, inorganic salts, chloroisocyanuric acid, snow melting agents, capsule filling particles, pigments, detergents, catalysts, strontium carbonate, silica, bleaching powder, pesticides, oxides, etc., as well as industrial regeneration dust materials: such as converters Dust, lead, zinc, aluminum dust, cast iron dust, filter dust, grinding and other dust, the material is compressed by mechanical pressure without adding any wetting agent to ensure the purity of the product.
The dry material is agglomerated into dense and hard large cakes under the pressure of the counter-roll granulator, which is called the extrusion pr
