Automatic Additive Dosing System
It is an automatic dosing equipment specially designed for weighting solid additive ingredients requested by the PVC formula. The solids can be powders, granules or crushed chips from recycling. Each solid additive is corresponded to 1 stainless steel bin with individual screw feeder. Inverter controlled screw feeders feeding each additive on the scale one by one according to formula. The whole dosing cycle only takes several minutes automatically within 0.3% accuracy. The dosed a batch size of additives are then fed into mixer with PVC resin and high proportion filler calcium carbonate for mixing process.
Product Description
Kenneth offers both semi-automatic dosing system and fully automatic dosing system which work with the heating mixer for a quick and precise preparation of one batch of raw materials. Those automatic dosing systems are upstream auxiliary equipment for PVC mixers.

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.
