Granulator is a material can be made with a specific shape moulding machines. Widely used in chemical, petrochemical, pharmaceutical, food, building material, metallurgy, environmental protection, printing, ceramics, rubber, plastic, and other fields. According to structure and work principle and a is divided into CF type Rotary steel with thaw melt material made grain machine (referred to steel with made grain machine) flat shaped double screw Rod extrusion machine turned drum dry producer machine on roll dry method made grain machine (referred to on roll made grain machine) on tooth made grain machine, disc type made grain machine for volume type measurement of to material equipment, it can uniform, and continuous to will material feed sent to Xia a process, and can bear larger of warehouse pressure. As the fine material feeding device, suitable for transporting powder, or small pieces of non-sticky materials, such as coal, cement, clinker, limestone, shale, coal gangue, powder, granular or lumpy materials such as clay. Can be used in concentration plant, coal plants and chemical, infrastructure and mechanical casting workshop, such as continuous homogeneous, quantitative feeding and ingredients used.
