Lab Kneaders

Laboratory kneader is one kind of small kneaders or micro kneaders , they are specially used for laboratory production and small batch production.  The laboratory kneaders is an ideal equipment for mixing, kneading, crushing, dispersing, and compounding various high-viscosity elastic-plastic materials,including various rubber ,plastic,EVA, TPR,Silicone , industrial chemicals etc.

The lab internal mixer small volume, and lower power consumption, which provides manufacturers with an optimum and favorable apparatus for saving raw materials.

This lab dispersion kneader feature uniform mixing, no dead angle, and high kneading efficiency, it is mainly used for research and development of the latest rubber and plastics material .

This lab kneader machine is equipped with PLC programmable LCD with human-machine interface operating system. The temperature, time and torque can display instantly. The mixing process will be completed automatically, simple and applicable with energy efficiency.

The lab kneader machine comprises a motor, cover press, main body, mixing chamber and rotor mechanism, gearbox, air control system, tilting machine, heating/cooling system, rubber belt transmission and base, etc. It can be made into vacuum, pressure, atmospheric, Normal temperature, high temperature, low temperature, etc.

The laboratory kneader has a pair of mating and rotating blades (usually Z-shaped) that generate strong shearing action to make semi-dry or rubber-like viscous plastic materials react quickly to obtain uniform mixing and stirring. In order to ensure product quality, the blade are usually made of stainless steel, alloy steel, manganese steel, and other materials .

The laboratory kneader can be designed as heating or non-heating according to the needs.  As to the heat exchange methods ,it usually include electric heating, steam heating, circulating hot oil heating, circulating water cooling, etc.

The laboratory kneader can be made into four types: ordinary type, pressure type, vacuum type, and high-temperature type. According to the material, it can be divided into carbon steel kneader, stainless steel kneader, and special material kneader. The form of temperature adjustment adopts methods such as jacket, steam, oil high-temperature kneader heating, water cooling, etc., and hydraulic cylinder turning and cover opening are adopted. 

Its discharge methods are available in hydraulic pressure, cylinder dumping, ball valve discharge, screw extrusion, hydraulic flap discharge, etc. 

The dispersion kneader machine can control and record the temperature, time, viscosity, and other related data in production in real-time through PLC.
