STRUCTURAL FEATURES: The internal mixers of this series 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 discharge device are all coated on with wearable hard alloyby 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 cylinders 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 maintain and have a long service life. The transmission system adopts a hard facing gearreducer, which has a compacted structure with higher transmission efficiency, 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 efficiency. 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 control system. It is easy to exchange the modes and reliable to operate the controller.
