ZS-200型高速團粒機是一種將廢棄的熱塑性薄膜及壁厚小於2毫米的制品進行直接造粒的設備，它可對軟聚氯乙烯、高低壓聚乙烯、聚苯乙烯、聚丙烯及其它熱塑性塑料的廢棄制品或薄膜進行團粒，亦可對發泡聚苯乙烯的廢棄制品進行造粒。
廢料投入機器鍋體內後，經高速旋轉的轉刀刃和固定刀刃的剪切作用，使物料很快被切成碎片，切碎後的料或片在轉刀盤的離心力作用下沿鍋體內壁麵流動，同時受下漿作用物料又上下翻動，由四周向鍋體中心方向運動，由於在高速下物料本身之間的摩擦以及與鍋壁和刀片的摩擦產生瞭大量摩擦熱，使物料溫度迅速上升達到半塑化狀態，互相粘連成小塊，在物料將要結塊前，將預先準備的定量水全部噴淋入物料中，冷水遇到熱的物料，迅速氣化，帶走物料表麵熱量，這樣使物料表麵急劇冷卻防止結塊，然後經轉刀刃和定刀刃間的破碎作用使之切碎成為顆粒（大小不齊不規則的粒料）。在切碎過程中，還可根據需要加入適當的顏料進行著色。
本機造出的粒料可以直接供擠出機，註塑機使用，對於要求較嚴的制品也可先經擠出造粒機再經塑化，造粒後使用。
ZS-200 model high speed granulating machine is an equipment which can granulate directly using the obsolete thermoplast film and the wares whose wall thickneeses are not more than 2mm. It can pelletize flexible PVE，high and low pressure pohyethylene、polystyrene、polypropylene and other obsolete thermoplast ware or film. And also can granulate obsolete ware of foamed polystyrene.
After put into the body of the machine, the waste marterial are quickly cut into pieces under the sheared cutting function of high speed rotary knives and fixed knives. The pieces move up with the centrifugal force of roraty cutterhead. And meanwhile they fall down because of gravity. Consequently, the pieces move from the wall of machine body to the center of the body. There are a lot of friction heat beacause of the fricton among the materials and between the wall and blades, which makes the temperature of the material increases fast and makes the plastics become sime-plastified and they stick to each other and become nubs. Before they materials become nubs, spray the prepared quantified water to the materials. Cooling water gasify when contact the hot materials and bring away the surface heat on the materials. That can cool down the materials surfaces and avoid them becoming nubs. And then the ratory knives and fixed knives cut them into pellets of all kinds of shapes. In the course of cutting, some color can be added into the materials.
The pellets material can be the used directly on extruder. Before the injector is used, the the products whoes reuqirements are very strict can be extruded firstly and then fused, thirdly granulated againd.
