Plastic Pelletizing Machine

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. So as to further dry the material before granulation. Drying reduce the pressure of the back channel device to deal with plastic moisture, thereby improving the efficiency of operation and improving the quality of products.

The drive of compactor controlled by inverter, together with sliding gate device installed on the outlet of compactor room, to guarantee ACS-Pro not only handle loosing material recycling but also rigid regrinds material re-pelletizing. It can handle both hard and soft materials. The sliding gate controls the residence time of the material in the compactor to achieve the effect of pre-drying and ensure that clean and dry material enters the barrel. Material that fails to achieve the treatment effect will not be able to enter the next process. PLC accurately controls the quantity of forced feeding materials to ensure production capacity. The compactor starts at low speed under the action of inverter. According to the filling amount of material and current, the rotational speed of cutter-head is adjusted to avoid the phenomenon of cutter-head jamming and save energy by 10-15%.

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.

Longer processing L/D, material o screw and barrels are alloyed materials, with 2 years warranty.
In the middle of processing section, sets the double-piston type screen changer, to let the melt pre-filtering before the vacuum degassing action, which can realize better homogenization and enhance the degassing performance.

Double-piston type screen changer with wide filtering area to present longer screen changing time, especially suitable to the high contaminated materials recycling and pelletizing.
Better volatilization performance, both the compactor and processing section set the volatilization device, and the melt will be degassed after filtering, especially good to the heavily printed materials recycling and pelletizing.
European standard Rittal structure electrical cabinet, which dust and water proof level is IP54; SSR+PLC principle to assure less energy consumption and realize whole system smart running.

Intelligence Start: One button only
Following set logistical sequence and materials processing requirement, interlocked system modules can start by “one button only”, to avoid mistake or fault occurred by manual operation.

Intelligence Stop: One button only
Each related modular part in ACS-Pro system available to shut down by only one button, to protect whole ACS-Pro system from fault hand operation.

Emergency Stop
Emergency stop function is available in ACS-Pro system in case that uncertain risk occurred during machine running.

Life safety protection
ACS-Pro system fully understanding safety issue during the actual operation step. Each operating position and rotating part equipped with electrical safe switch, to guarantee producing process safely and ensure clients’ staffs life safety from potential risks during machine’s running.

Plastic performance keeping
Thanks to precise temperature controlling and optimized plasticization design, ACS-Pro system ensure the reliable quality output of plastic granules.

Protection of over-heating to compactor
Following the logistics of each modular part in ACS system and with well understanding on each recycle specification, ACS system can guarantee related recycles with optimized pre-heating and compacting conditions in the compactor, preventing plastic recycles from overheating or degradation in the compactor.

System program remote monitoring and transmission system,bluetooth both are available for ACS-Pro system realizing functions of remote monitoring and information transmission.

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. Different from traditional screen changers, which requires timely change the dirty wire mesh, the SCF system will present continuous filtering performance, and remove the contaminates from the surface of steel screen plate automatically.The SCF filtration system consists of hardened steel screen plate, rotating unit, hydraulic section, contaminates removing blades and discharging screw.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
