The working principle of kneader is that a pair of matched and rotating ∑ blades produce strong shear effect, which makes the semi dry or rubber like viscous plastic material react quickly, so as to obtain uniform mixing and mixing. Kneader is mainly composed of kneading part, base part, hydraulic system, transmission system and electric control system. The hydraulic system uses a hydraulic station to control the large oil cylinder to complete the opening and closing function. The hydraulic system uses a hydraulic station to control the oil cylinder to complete the functions of turning over the cylinder and opening the cover. The detailed parameters can be arbitrarily selected and required by the user, so the operation is convenient and reliable. The transmission system is composed of motor, reducer and gear, and the motor is matched according to the model of kneader. The transmission part of kneader is synchronous speed of motor, which is transmitted by output device to speed reducer through elastic coupling, so that it can reach the specified speed. It can also be adjusted by frequency converter. Kneader has two ∑ blades. The speed of the two blades is different. Different speeds can be set according to different processes. The most common speed is 42 / 28 rpm. Kneader can be designed into heating and non heating forms according to the requirements. The heat exchange modes are usually: electric heating, steam heating, circulating hot oil heating, circulating water cooling, etc. Kneader discharging methods include hydraulic cylinder dumping, ball valve discharging, screw extrusion, etc. SUS304 stainless steel is used to ensure the quality of products.
