As a open type two roller mixing mill, it consists of seat, frame, roller, driving gear, lubricating device, cooling and heating device, adjusting device of roller nip, safety brake, motor and reducer, etc. The roller, with smooth surface after polished, is made of chilled cast iron. Steam and cooling water can be inputted in the empty roller to adjust temperature of roller. Two rollers rotate reversely with different speed, so that rubber materials are drawn into the gap of the two rollers for processing.

The machine is applicable for plasticating and mixing rubber and plastics. Structural features: The internal mixers of this adopt elliptical tangential rotors. The wings and working surfaces of the rotors, the internal surfaces of the mixing chamber, and the working surfaces of the pressing ram device and the discharging device are all coated on with wearable hard alloy by built-up welding method, which are durable and corrosion proof and have a long service life. The rotors, the mixing chamber and the discharging door are all structured with circulating channels to realize the circulation of heat transmission mediums. According to different processing requirements, the mixing materials may be heated by hot steam or cooled by cold water. The mixing chamber is a combined configuration, which is convenient for assembling, disassembling and maintaining. The drop-door discharge device is driven by two reciprocating oil cylinder which directly pull the locking plate to lock the discharge door. The device provides fast discharging and reliable airproof. The rotors are supported by rolling bearings, which are easy to maitain and have a long service life. The transmission system adopts a hard facing gear reducer, which has a compacted structure with higher transmission effciency, lower noise and longer service life. The pressing ram device may be driven by pneumatic cylinder or oil cylinder to press onto the mixing materials to force them equally mixed so as to increase productive effciency. Mated with the electric controller, the pressing ram device can automatically add pressure, release pressure or just keep floating. Both manual and automatic modes are arranged to operate plc electric system. It is easy to exchange the modes and reliable to operate the controller.
