Open mill is a double roller machine, using different speed relative movement of the two rollers to generate shear force to plasticity. Operation is to continue to play the operation of the triangle package.
Mixer is the use of the internal design of the blade relative movement of the regular contraction of space to produce shear force.
The structure of opening mill is simple and low cost, but the labor intensity is big, the pollution is big, and the body harm to the workers is big.
Internal mixers are more expensive, but they can be heated, they can be vacuumed, and there are also pressurized internal mixers that can be used to process refractory materials. Low labor intensity and strong adaptability.
Two Roll Mill is one of the important equipment in plastic processing,It can make the raw materials and additives mixing well.
The plasticizing with the opening mill is mainly through the shear and extrusion effect of two relatively rotating rollers on the rubber material, so that the original macromolecular chain of the rubber material is broken, so that the original elasticity of the rubber material is reduced and the plasticiability is improved, which is conducive to the following processing procedures.
Design principle
Two rollers go around with a certain speed,they supply the shear force and temperature for sample.
