With more than 20 years of research and development, the performance and output of the newest co-rotating twin screw extruder has been improved greatly. Equipped with high efficiency motor and gear box, the co-rotating twin screw extruder compounding pelletizer has a powerful extrusion capability.
Kenneth selects and uses top brands of motors and gear reducers on the extruders. Those high efficiency motors and superior gear reducers provide powerful energy source for extrusion. The motor and gear reducer combinations enable extrusion screws rotating at different speed smoothly and quietly.
Extruder Screw&Barrel-Core of Melt Compounding Technology
The selection of screw is based on customer’s formulation. Different material characteristic requires different screw configuration and length/diameter ratio. Kenneth team evaluates formulations and finalizes the screw to meet customer’s requests. Kenneth screw is made of 40CrNiMoA and high speed anti-wear tooling steel W6M05Cr4V2 with a stiffness of HRC62~64. The extruder barrel is made of double metal alloy with a stiffness of HRC64~68. The excellent materials and optical screw helical profiles contribute a outstanding extrusion capacity and long service life.
The screw&barrel of Kenneth’s single screw extruder is customized to satisfy customers’ formulations. The optimal configuration of screw zones brings high-efficiency extrusion system and ensures high-quality pellet. Thanks to our strict quality management that guarantees good quality and long service life of our screws.
Die
The die material and mold runner must be selected and designed according to the physical properties and characteristics of plastics to avoid occurrences of uneven material flow rate, retention, excessive molding pressure, in-mold temperature increase, decomposition and carbonization or other situations that may damage material properties of plastics.
Multiple Pelletizing Systems
Melt plastics after extrusion goes through the die mounted at end of extruder and forms strands with a diameter of 3.2mm/4mm. Hot strands emerged from die are cut into pellets by various cutting devices. To get the final pellets for packing process or storage also requires a cooling device, either air cooling or water cooling. Anyway, dryers may be needed for some materials with high moisture absorption characteristic or cooled by water. The most commonly used pelletizing systems on Kenneth melt compounding pelletizer line are as follows:
- Water Cooling Strand Cutting Pelletizing System
It is the most widely used pelletizing system which almost fit for all materials. The entire system is famous for its simple configuration, cost effective and easy for operation&maintenance.
- Air Cooling Die Face Cutting Pelletizing System
The pelletizing system is mainly used for the materials which are easy to absorb water, have drying problems or have strict moisture requirements. Since the whole pelletizing process is performed under non-water condition, no drying process or additional dryer is needed.
- Water Ring Die Face Cutting Pelletizing System
The pelletizing system is suitable for most filling or non-filling thermal plastics. Water circulation running through the die ring plate to ensure an average temperature distribution of the die plate while avoid direct contacting of water and hot materials. The system is fairly compact which saves space for customer.
- Mist Jet Off-center Cutting Pelletizing System
The pelletizing system effectively increases the extrusion capacity and reduce the extrusion pressure. The die and mold runner design is fairly simple and compact. The system is suitable especially for processing PVC, EVA and cross-linked materials which are thermal sensitive. The angle and axial distance of cutter are easy for adjustment.
- Underwater Cutting Pelletizing System
To use which pelletizing systems is mainly determined by the formulation, and secondly by output requirements, space limitation, cost etc. Kenneth team evaluates all requests and conditions from customer, then provides the best solution to satisfy customer.
Product Features
Modular Designed, Maximum Flexibility & Mobility
Kenneth mixers are modular designed with maximum flexibility for various applications. Each mixer is tailored by different PVC recipe, processing and throughput requirements based on Kenneth’s expertise in the area of PVC compounding and mixing.
Whole Series, Full Range
Kenneth has a full range series of heating mixers, capacity from lab scale 10 liter to industrial production scale 1,500 liter. Full range series of cooling miers, capacity from 200 liter to 6000 liters. Throughput of PVC compounds can be 30kg/hr(SHR-10) to 4,000kg/hr(SHR-1500).
Solid Materials, Precise Assembled, Quality Crafted
The machine structures of Kenneth heating mixer are made of carbon steel been welded together by experienced welder. Inner surface of mixer tank, mixing tools, discharger inner surface wherever contacted with resin are made of stainless steel 304. The solid machine structures minimize vibration meanwhile the precise assemble of all mechanical parts ensures a comfortable noise level even at intensive mixing operation.
Reliable Components
Kenneth mixer adopts industrial standard electrical components from world renowned brands i.e Siemens, Schneider, OMRON, ABB etc. It is a consideration of quality assurance and easy sourcing for replacement of broken parts wherever the customer is all over the world.
Electrical Safety & Certificate
Safety of equipment and protection of operators are the top guideline throughout the design& engineering of both mechanical and electrical aspects. Strict process control during fabrication and assembly of single machinery or whole line. Kenneth mixers and mixing lines offer multiple certificates as requested e.g. CE, UL, CSA etc.
Intuitive Operation&Diverse Control Modes
Depends on the automation level and related accessories, the control of mixing process can be manual, semi-automatic or fully automatic. The first 2 control modes are usually achieved via button operation on the electrical cabinet. While the fully automatic mode requires an additional touch screen(Siemens S7 PLC) which visualizes all processes vividly, integrates all control operations and real time monitoring of all components etc. Remote maintenance module is optional for remote diagnosis of malfunctions or update of control system.
