Description
Laboratory two roll mixing mill is one kind of mixing processing machinery with adjustable gap between rollers composed of two parallel rollers, it is mainyl used to mix and plasticize rubber (natural or synthetic) into various mixed uniform compounds material for calender machine
The laboratory two roll mill machine mainly consists of seat, frame, rubber, driving device, lubricator and cooler, range adjusting device of roller. etc. it is used to mix and knead raw materials and additives evenly ,it is suitable for raw rubber, synthetic rubber, thermoplastics masterbatch or E.V.A.with chemicals into final materials.
Two roll rubber mixing mills machinery are mainly used in rubber product factory ,such as natural rubber refining, raw rubber and compound mixing, Rubber beating mixing and rubber tab letting.
The two rolls are made of vanadium titanium metal alloy chilled cast iron,whose hardness can reach up to 70HB.
The rolls are driven by a geared ac motor. The rear roll is driven by spur gears for a constant friction. Modifications for speed and friction are possible to meet individual requirements within certain steps.
These rubber mixing mills are mainly used in PVC, plastic,rubber , polyolefin, film, coil and polymer blending, pigments, masterbatch, stabilizers, stabilizers and other industries. After process by this rubber mixing mil ,the physical of raw material would change and contrast. Such as: color dispersion, light transmission, the gloss of the surface of the material, its strength, plasticity, hardness and so on.
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.
*PRESSURE LID: Steel fabricated hard faced at mixing contact area, Jacketed for effective heating / cooling.
DUST SEALS: Specially designed to keep environment Cleanliness & are easily replaceable.
*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.
The Rubber Mixing Mill Serves Many Functions In Various Industries
1. Rubber Processing : Perfect for mixing ,kneading and blending rubber compounds ,ensuring uniformity and consistency in the final product.
2. Manufacturing : Ideal for the production of rubber sheets, belts ,tires and other rubber-based products with precise specifications and quality control.
3. Research and Development : Facilitates experimentation and testing of new rubber formulations ,enabling innovation and improvement in product performance.
4.Quality Assurance : Guarantees the integrity of rubber compounds by thoroughly mixing ingredients ,eliminating air bubbles ,and dispersing additives evenly.
5.Customization: Offers flexibility in adjusting mixing parameters to meet the unique requirements of different rubber formulations and applications.
