Description
The two-roll rubber mill is a mixing processing machine used to process rubber (natural or synthetic) into various compounds material,this mixing machine mainly comprises two rolls, metal frames, beds, bushings, bushing lubrication, roll gap adjustments etc.
The two rolls are made of vanadium titanium metal alloy chilled cast iron, whose surface is hard and wear-proof, and its hardness can reach up to 65-70HS. These hollow rolls adopt double auto-centring rolling bearings lubricated by lubrication grease.
The rolls rotate in opposite directions at different speeds; usually, the rear rolls have a higher speed than the front rolls. They mix and knead the raw material uniform and get the ideal compound material. The rear roll usually has a higher speed than the front roll.
This allows for the proper mixing and kneading of the raw materials into high-quality compounds and is ideal in use. The laboratory rubber mixing mill machine is equipped with an emergency brake device. Users can immediately draw the safety pull rod or press the emergency button, and the machine will stop immediately to guarantee the operator’s safety.
Our rubber mixing mill machine is used for mixing and kneading raw rubber, synthetic rubber, thermoplastics, hot melt adhesive, chemical medicine or E.V.A with chemicals into final materials ,they are available in various sizes ranging from 3, 4, 5, and 7 inches.

How Does a Simptek Laboratory Dispersion Kneader Work?
This lab dispersion kneader is specially designed for mixing a variety of materials ranging from low viscosity adhesive to high viscosity polymers with various additives, such as fillers, plasticizers, and vulcanizing agents. The laboratory kneader feature with small volume, and lower power consumption,it is a high-performance mixing device specially used for for formulation research and small-scale manufacturing.
The dispersion kneader has two blades that rotate toward side to side to cut, mix and blend materials applying different speeds and shear force,which accordingly provide excellent cross mixing of all raw materials.
Key Components of a Rubber Kneader
*Mixing Chamber: The mixing chamber is a critical part of this laboratory dispersion kneader, which directly impact mixing efficiency and product quality. The mixing chambers of our laboratory kneader machine is made from wear-resistant alloy steel materials, which is duly polished and hard chrome plated, adding a best service life to the kneding machine with an adjustable tilting angle (max. 140) for easy discharge.
*Rotor Design: Made of alloy cast-steel, spirally annular design, which is crucial for effective kneading . We offer various designs, including interlocking and meshing types, to meet different material and process requirements. Interlocking rotors provide efficient mixing for general rubber; meshing rotors are ideal for applications needing higher mixing uniformity, such as high-filler rubber.

*Control System: Available in Manual push button electrical control or Automatic by electrical Control panel with P.L.C (Programmable Logic Controller) as per clients’ requirements. The PLC systems, allows users to set and monitor temperature, pressure, and time via a touch screen.
Applications of Rubber Kneaders
*Tire Manufacturing: In tire production, the laboratory dispersion kneaders are essential for mixing natural or synthetic rubber with various additives, such as fillers, plasticizers, and vulcanizing agents. Our equipment precisely controls temperature and pressure during kneading, enhancing tire grip and wear resistance.
*Rubber Product Compounding: Dispersion kneaders are widely used to produce rubber compounds like sealants, silicone rubber ,gaskets, hoses, and conveyor belts. Efficient mixing and material distribution enhance the physical properties of rubber, such as strength, elasticity, and chemical resistance, making our equipment suitable for the automotive, aerospace, and construction industries.
*Polymer and Chemical Processing: In the polymer and chemical industries, this laboratory dispersion kneader produce rubber and plastic products such as films, sheets, adhesives, and Pharmaceutical industry.
