The open type rubber mixing mill is mainly used in rubber processing line for plasticating, sheeting, thermal refining and mixing. The equipment is mainly composed of front & rear rolls, left & right frame, gap adjustment device with overload protection, base, roller temperature adjustment device, front & rear speed ratio gear reducer, lubrication device, emergency brake system and motor, electric cabinet and so on. The rolls are made of alloy chilled cast iron with hard and wear-resistant surface and middle hollow, the working temperature of rolls is controlled by steam, cooling water or oil passed through the cavity to meet the demand of rubber processing. Equipped with overload protection and emergency braking device, which can protect main parts from damage by pulling the braking rod, when overload or other emergency accidents happens. Manual or electric gap adjustment device to be selected according to customers’ demand. The equipment has the features of safety, reliability, easy to operate and install, low noise, high efficiency, long life and so on.
