Lab Two Roll Mill
The lab two roll mill is used to mix the raw material and additional agents uniformly for testing, and apply the experiment results and its ratio in the production line to satisfy the requirements of quality and color which specified by the customer.
Lab two roll mill is widely used in rubber, plastics industries. Such as polyolefin, PVC, film, coil, profile production and polymer blending, pigments, masterbatch, stabilizers, stabilizers and so on. The main purpose is to test raw materials's physical properties change and contrast after mixing. Such as color dispersion, light transmission, substance table.
Addictives in the form of particles, powder, and liquid are allowed to be added as activators, fillers, or oils into the base.
With the rotation of the two rolls, the internal macromolecular chains of the raw materials are broken accordingly for mastication, and the compositions inside the rubber compound are further dispensed to complete mixing, thus producing sheet-like materials for further molding desired products.
During the process, the operator needs to keep cutting, folding, and rolling the material on the front roll manually with a tool made of bamboo or wood to enhance the uniformity of the compositions.

Reverse gate
The operator can tap the gate with either knee in an emergency.
The roller will automatically stop rotating and reverse 1/4 turn to eliminate thedanger once the gate is tapped.
In addition, multiple safety measures, such as protective brackets over the rolls withthe emergency stop function, can be added to our open mixing mills.
