Working steps of ACS 800/120 compacting and pelletizing system
1. Feeding: 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 control system, to warn and stop the system, in case that metal is found in feeding section.
2. Crushing and compacting: 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.
3. Plasticization and degassing: A specialized single screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in a 32 to 34D 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 some water content.
4. Melt filtration: 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 quality of the input material as well as the planned use of granules.
5. Pelletizing: die-face water ring pelletizing system set as the standard granulating method in ACS system. Self-adjusting pelletizing head for the best granulate quality and long uptime thanks to consistently correct blades pressure. RPM of rotatory blades is automatic based on melt extruding pressure. Advanced dewatering vibration sieve combining with horizontal-type centrifugal dewatering present high performance dried pellets.

Advantages of ACS 800/120 compacting and pelletizing system
1. Combine crushing, compacting and pelletizing steps in one system, less-labor cost;
2. Higher efficiency feeding, suitable to film, filament, raffia, foaming materials;
3. Higher output and lower energy consumption.
Laboratory hopper mixer is mainly used for the tests of mixing different components of dry powders with dry powders, granules with granules, or powders with granules in laboratories. It is an ideal machine for exploring the best process parameters in material mixing, and a mechanically and electrically integrated advanced experimental machine.
Features:
The laboratory mixer is installed on a moveable base. Its main parts include machine frame, rotation system, electric control system, hopper, etc. The conical mixing hopper is mainly composed of hopper, hopper cover, ferrule, butterfly valve, etc.
The hopper that can rotate at 360° is installed on the rotation shaft by adopting the cantilever fixing mode. As the symmetrical axis of the hopper forms an included angle with the rotary arm rotation axis, different components of materials will make three-dimensional movement in the closed hopper, producing strong turning and high shearing and achieving the best mixing effect.
The rotation system is a key system for completing the mixing function. The rotary motor is a low speed high torque speed reducing motor, which is the power unit for mixing. The rotation shaft is installed with sensing components. When the gyrator turns to the set position, the sensor installed on the machine frame sends the sampling signal. The signal passes through the PLC system, which reads the hopper rotation speed and position information, continuously displays rotation speed and accumulated number of revolutions on the touch screen, and sends stopping instructions according to the set time. The hopper stops rotation, and stops at the best discharging position under the action of the brake motor.
The electric control system is mainly composed of two parts such as the electric cabinet and sensor. The core control parts PLC controller and frequency converter are installed in the electric control cabinet. During the use, the operations of electric appliances are mainly completed on the operation panel (touch screen) of the electric control cabinet, including printer, touch screen, power switch and emergency stop switch. The touch screen displays running time, rotation speed, etc.
