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 is equipped with air exhausting device. With the mechanical work of rotor knife and stator knife at the bottom of compactor, the temperature of compactor and material will gradually increase after continuous cutting and friction, and the moisture and dust on the surface of raw material will float to the top of compactor. The device can effectively remove moisture and dust, which will avoid using additional energy consumption to deal with the moisture.
Intelligence Start: One button only Following set logistical sequence and materials processing requirement, interlocked system modules can start by "one button only” Intelligence Stop: One button only Each related modular part in ACS system available to shut down by only one button. Emergency Stop Emergency stop function is available in ACS system in case that uncertain risk occurred during machine running.
System program remote monitoring and transmission system,bluetooth both are available for ACS-Pro system realizing functions of remote monitoring and information transmission.
The rotatory blades of compactor with cut up incoming scraps. Frictional heating which caused by high speed rotatory blades will heat and let scraps shrinking just below their agglomerating point. Optional 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.
Because of the super L/D ratio, the single stage extruder in the production line can be used as a double- stage extruder. After the middle double-piston type screen filter, another filter can be added at the end. The double filter standard can improve the quality and performance of the final product particles.
By screw’s rotation, the plastic material goes forward, to finish the processing of compacting, melting, homogenization. Material of screw adopts qualified nitride steel(38CrMoAlA), process of CNC, with nitride treatment, has the ability of corrosion resistance and wear-resisting. With the specialized design of screw, even running with high speed, the material of polyolefin can be well melted under lower temperature and lower melting pressure.
It consists of two sets of Single-Screw extruders , suitable for printing ink heavy, high moisture content, poor fluidity and temperature sensitive, high impurity content materials which requires the double filtration system, multiple exhaust and other higher requirements, and a longer process.
This model combines our self-developed self-cleaning filter.The new SCF self-cleaning filtration system makes non-stopping recycling extrusion, especially suitable to highly contaminated materials re-pelletizing. SCF filtration system can handle and remove up to 5% contaminates in the melt flowing, can separate the contaminates as: paper, wood, aluminum, unmelted plastic and rubbers etc.
A regular single-plate/piston double-station screen changer or non-stop double plate/piston four-station can be installed on head of extruder to present significant filtration performance. The requirements on the filter technology depend heavily on the quolity of the input material as well as the planned use of granules.
This is the most appropriate process for the need for better melt filtration and higher production. In the first stage,two or more single screw extruders can be designed for the two-stage pelletizing production line, and then they can enter the second-stage extruder at the same time.
Die-face water ring pelletizing system set as the standard granulating method in ACSS-HTM system. Self-adjusting pelletiziin head for the best granulate quolity and long uptime thanks to consistently correct blades oressure. RPM of rotatory blades is automatic based on melt extruding pressure.
Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption.
Final output: plastic particles
The drying shaker together with the horizontal centrifuge can get a good drying result, and less energy consumption.
