XK-450 Open Mixing Mill Main structure of Rubber Mixing mills 1. The machine consist of Base, frame, the rollers, drive system, roll gap adjustment device, heating and cooling device, safety brake, lubrication system, electric control system, motor and reducer etc. 2.Materials of Rolls: Cast iron alloy (LTG-H), whose surface hardness is HS, 68~75 is after quenching and precision processing. The working surface is well grinded and machined. The roller adopts double auto-centering rolling bearings, which are auto lubricated by lubrication grease. 3.Drive system: the reducer has hard tooth surface reducer. the motor is connected with reducer by elastic shaft coupling. The reducer structure type is double out shaft transmission, which is connected with front and back rolls by universal shaft coupling of nylon stick pin. All the drive gears of reducer are concentrated inside the case, which is well lubricating with spray type and has long useful life. 4. Roll gap adjustment: electric automatic 5. Motor: Frequency control of motor speed 6. Reducer: Airtight leaching oil type, ZSYE reducer (There are a variety of choice, the price is different), Almost no noise, safety . 7. Braking capacity: The machine has safety device, overload, and safety piece of destruction, to protect the major parts. pictures |
