    • An apparatus and method for the pelletization of waxes, wax-like and other materials having a sharp melt point include a vessel for forming the wax into a hot molten material. A heat exchanger then cools the molten wax to a temperature just above its melt temperature. The cooled liquid wax is fed to an extruder which further reduces the temperature and mixes the liquid wax into a thoroughly mixed extrudable solid wax. The solid wax is then extruded through die orifices of a die plate into a cutting chamber, and a rotary cutter cooperating with the die face of the die plate cuts the extruded solid wax strands into pellets. The die plate, cutting chamber and rotary cutter can have the same structure as an underwater pelletizer, but operating without water or liquid as a dry face pelletizer. The thus formed wax pellets drop out of the cutting chamber by gravity through an opening in the bottom thereof.
    • 用于将蜡,蜡状物和具有尖锐熔点的其它材料造粒的装置和方法包括用于将蜡形成热熔融材料的容器。 然后热交换器将熔融蜡冷却到刚好高于其熔融温度的温度。 将冷却的液体蜡进料到挤出机中,进一步降低温度,并将液体蜡混合成完全混合的可挤压固体蜡。 然后将固体蜡通过模板的模孔挤出到切割室中,并且与模板的模具面配合的旋转切割器将挤出的固体蜡链切割成颗粒。 模具板,切割室和旋转切割机可以具有与水下造粒机相同的结构,但是在没有水或液体的情况下作为干面造粒机操作。 由此形成的蜡颗粒通过重力通过其底部的开口从切割室中脱出。

    • A melt cooler and valving system for an underwater pelletizer has a diverter valve that facilitates multiple modes of melt processing. The cooler has a cooler inlet line that conveys the melt to the cooler, and a cooler outlet line that conveys the cooled melt from the cooler. The diverter valve is configured to convey the melt to and from the cooler during a cooling mode of operation, to convey the melt around the cooler during a bypass mode of operation, and to drain the melt from the cooler and the diverter valve during a drain mode of operation. The diverter valve is compact and therefore contains a minimum of product inventory. The valve is streamlined and direct in its bypass mode, and includes a drain capability to allow for faster, easier cleaning of the process line, which in turn provides a fast changeover time with less lost product.
    • 用于水下造粒机的熔融冷却器和阀门系统具有促进多种熔体加工模式的分流阀。 冷却器具有将熔体输送到冷却器的更冷的入口管线,以及将冷却的熔体从冷却器输送的冷却器出口管线。 分流阀构造成在冷却操作模式期间将熔体输送到冷却器,以在旁路操作模式期间将熔体输送到冷却器周围,并且在排水期间从熔炉和分流阀排出熔体 操作模式。 分流阀紧凑,因此包含最少的产品库存。 该阀是流线型的并且以其旁路模式引导,并且包括排水能力,以允许更快,更容易地清洁生产线,这反过来提供快速的切换时间并减少损失的产品。
