The distributor of the pelletizerwill uniformly distribute the materials from the upstream heat melting process on the steel belt moving at constant speed; the continuous spaying and cooling device is set under the steel belt, rapidly cooling and solidifying the materials on the steel belt during the movement, thus to realize the pelleting and forming purpose. According to thephysical property and use requirements, the continuous dripping, continuous bracing and full-width overflow forms may be selected by the distributor, thus to meet the requirements of producing products of different shapes, including semi spherical, strip and sheet.
The equipment is applicable to various materials with requirements of condensation pelleting, bracing and cutting, and cooling, sheeting and crushing within 250℃ of melt point (soften point). Typical materials include: sulphur, paraffin, resin, asphalt, maleic anhydride, meta-anhydride, stearic acid products, hot melt adhesive, organic intermediate, compound fertilizer, rubber, plastic, and other auxiliaries.
This equipment is widely applied to fast cooling process of powder materials and cake-shaped viscous materials, such as emulsion explosive matrix, crystal matrix and sodium fluosilicate.
1. It can reduce the dust, improve the operation environment, enhance the productivity with continuous operation, and increase the product value with well-structured granule.
2. The thin steel belt is adopted for heat transferring and forced spray cooling to rapidly cool and solidify the hot melt materials.
3. Due to the reverse bending of steel belt at the discharge end, the junction surface of solidified materials and steel belt is separated to generate little dust during the discharge and protect the granulate shape.
4. The frequency control is adopted by the steel belt and distributor, resulting in convenient adjustment and control according to productivity, environmental condition and physical property.
