Hot Sale Rubber Compound Mixing Machine / Two Roller Rubber Mixing Mill Machine
Two roll mixing mills are equipped with a specially designed hydraulic stock blender to assist the operator in mixing the rubber material and chemical powder. It reduces the labor indulgence, provides safer working conditions, lowering the material temperature and speeding the mixing rate of the compounds.
The speed of the stock blender can be changed as per requirement irrespective of the roll rpm

Should you buy a Stock Blender for your Open Mill?
The Stock Blender is an add-on accessory mounted on top of an open two roll mill. It aids in rubber blending by pulling the mix compound from the front roll of the mill and guiding it to the nip gap between the two mill rolls.
A stock blender helps in homogeneous mixing and repeatability of the mixing operations. Many companies use them on the Open mill (also known as dump mill) below the internal mixer. After masterbatch mixed in an internal mixer, curatives are added and final homogenization done on these mills. Because the mill helps incorporate undispersed curative or fillers that might have fallen off the ram or drop-door when the batch was dropped.
In a different scenario, if you need to drop the mix batch at a higher dump temperature, you could use the stock blender to take some heat out of the batch and then add the curatives on the mill. Reduction in temperature is obtained by allowing the batch from the mill roll airborne to pass over the water-cooled blender roll before it returns back to the nip gap. When these mill rolls (centrally cored or peripherally drilled design) are properly cooled, the stock-blender allows you to reduce the batch’s temperature continuously for lower viscosity compounds.
