1.The roller press granulator is working at room temperature, forming at one time without drying process,has the advantages of less investment, quick effect, good economic returns.
2.The roller extruding machine power is small with reliable operation, no waste discharge, stable operation, convenient maintenance, process layout is reasonable, technology is advanced,production cost is low. 
3.The roll press granulator machine can be used for extensive applicability of 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.)
4.The roller press granulator machine is especially working on raw earth carbonate ammonium sulfate, compound fertilizer, to fill the gap and in the leading domestic level, is the project promoted by the national environment protection technology department.
