Double stage granulating line machine
Double stage extruder plastic granules production line extruder machine Mother baby extruder granulation machine
Mainly used for processing the old or the waste plastic film(Industrial packaging film, agricultural mulch, greenhouse film, beer bag, handbags and so on), woven bag, the agricultural convenient bag, plastic basin, plastic barrel, soft-drink bottle, furniture and the daily supplies. It is suitable for most common waste plastics and the most widely used in waste plastics recycling industry, and the most popular plastic recycling machinery.
1.All recyclable plastic is sorted and broken and cleaned without drying or drying. It can be produced and keep wet.
2.From the raw material crushing, cleaning, expected to make particles are all automatic.
3.Make full use of high-pressure friction continuous heating system, automatic heating production to avoid continuous heating, truly realized the electricity saving.
4.The electric and the machine parts are separate, operation is simpler, use more secure.
5.The screw and the cylinder are made of the carbon steel materials, wear well.
6.The appearance of the machine can be painted according to customer's requirement and the surface looks nice.
Single part introduction:
As standard design, plastic scraps such as film, filament, raffias conveyed into the compacting room through belt conveyor; to handle rolls’ scraps, roll hauling off device is an optional feeding method. Motor drives of conveyor belt and hauling device cooperate with ABB inverter. Feeding speed of conveyor belt or roll hauling off is fully automatic based on how full the compactor’s room is. Metal detector can be combined with belt conveyor, and can interlock with contrl system, to warn and stop the system, in case that metal is found in feeding.
Compactor / Agglomerator
The rotatory blades of compactor will cut up incoming scraps. Frictional heating which caused by high speed rotatory blades will heat and let scraps shrinking just below their agglomerating point. Optimal designed guide structure compacts the material and directs it into extruder screw. Crushes, dries and compacts the material which enables a fast and stable feeding from the compactor directly into the extruder.
A specialized single screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in a 36D processing section. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to heavy printed film and material with water content.
The requirements on the filter technology depend on the characteristics of the input material as well as the planned use of final granules. Regular single-plate/piston double-station screen changer or non-stop double-plate/ piston four-station can be installed on the end of the extruder to present significant filtration performance.
Electric control system
One button “START”,One button “STOP”, lEmergency Stop. lProtection switch. Every operation position and rotary parts are equipped with limit switches for safety protection. lPrecise temperature control, optimized plasticization design, ensure reliable quality of granules. lProtection from over-heat in the compactor.
