固体熔融冷却造粒机Solid Melting and Cooling Pelletizer

一、工作原理及应用范围介绍  Introduction of Working Principle and Scope of Application

通过造粒机布料器将来自上游工序热融态物料均匀地铺设于其下方匀速移动的钢带上，钢带下方设置有连续喷淋、冷却装置，迫使钢带上方的物料在移动过程得以快速冷却、固化，从而达到造粒成型的目的。依据物性和使用要求，其布料器可选择断续滴下、连续拉条和全宽度溢流等不同形式，来满足生产半球状、条状、片状等不同形状的产品。

本装置适用于熔点（软化点）在250℃以内需冷凝造粒、拉条切粒和冷却结片破碎的各类物料，典型应用物料有：硫磺、石蜡、树脂类、沥青、顺酐、偏酐、硬脂酸类产品、热熔胶、有机中间体、复合肥料、橡胶和塑料等多方面的助剂类产品等。

本装置还可广泛适用于粉末状物料和糕团状粘性物料的快速降温冷却过程，如基质、水晶石基质、氟硅酸钠等。

    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.

二、特点   Characteristics

1.减少粉尘，改善操作环境；连续作业，提高生产效率；颗粒规整，商品价值得到提升。

2.采用薄钢带传热和强制喷淋冷却，使热融物料得以迅速冷却、固化成型。

3. 由于钢带在卸料端的换向弯曲，使固化物料与钢带的结合面产生分离，卸料时粉尘极少，颗粒形状得到完整保护。

4. 钢带和布料器均采用变频调速，可根据生产能力、环境条件和物性方便地调节与控制。

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.
