Rotoform laboratory

Zhangjiagang Raidsant Machinery Co., Ltd. is majored in developing and manufacturing innovative powder cooling pelletizing machinery. With nearly 20 years' production history, we have a good market in more than 20 provinces in China, and some of our products were exported to Spain, America, Russia and Korea, etc. Our products: DZ rotary type cooling pelletizer, rotary type steel belt cooling slicer, double-belt cooling unit, etc. have got many national patent certificates.

Application: 
The plant is applied to products with the melting point below 250°C for curing and shaping. Typical applied materials include: Sulphur, Paraffin Wax, Resin, Asphalt, Maleic Anhydride, Trimellitic Anhydride, Salt Stearate, Hot-Melt Adhesives, M-Phenylenediamine, Urea, Rubber and Plastic Auxiliary etc.

Working principle: 
Melting material, through material distributor, drips down to the steel belt which is moving evenly. Under the belt, there are continuous sprayer and cooling device which can cool, solidify and pelletize material on belt as soon as possible. According to material feature and process requirements, outward turning, rotating, reciprocating, gate types are available for your choice. Based on material feature and use requirements, material distributing forms like incontinuous dripping, continuous strip, full-width overflowing are available, and with hemispheric, bar, flake products.
