Intensive mixers are ideal equipment for kneading, mixing, vulcanizing, and polymerizing high-viscosity, elastoplastic materials. They are used in the production of silicone rubber, sealant, hot melt adhesive, food gum base, and more. An intensive mixer is a mixing and stirring device, commonly featuring two Sigma blades arranged in an adjacent, counter-rotating differential pattern, where one stirrer rotates faster than the other to generate shearing force. The varying speeds of the blades enable the mixing material to be quickly sheared, ensuring a uniform mixture.
Vacuum kneaders are a type of kneading machine, primarily used in the chemical production fields such as silicone rubber, sealant, butyl rubber, and thermoplastic adhesive. Kneading machines are typically composed of several major components, including the kneading system, vacuum system, heating system, cooling system, and electrical control system.
The kneader operates by a pair of Σ blades that interact and rotate, generating a strong shearing action. This rapidly facilitates reaction and achieves uniform mixing of semi-dry or rubbery, thick plastic materials.
The kneading machine is primarily composed of five major parts: the kneading section, base section, hydraulic system, transmission system, and electrical control system. The hydraulic system is operated by a hydraulic station to control the large oil cylinder for opening and closing functions. The hydraulic station also operates the cylinder for functions such as tilting and opening. Detail parameters can be customized by the user to their preference, ensuring easy and reliable operation. The transmission system consists of an electric motor, a reducer, and gears, which are matched with the kneading machine model.
The kneading machine's transmission section is driven by the motor at a synchronous speed, passing through an elastic coupling to the reducer, where it is then transmitted to the output device to drive the thickener to reach the specified speed. It can also be adjusted using a variable-frequency inverter.
The kneader features two Sigma-type blades, with varying speeds between the two. The rotational speed can be set differently according to different processes, with a common speed of 42/28 RPM.
The kneading machine can be designed in both heated and non-heated versions to meet requirements. The heat exchange methods usually include electric heating, steam heating, circulating hot oil heating, and circulating water cooling, etc.
The discharge methods of the kneader include hydraulic tilting, ball valve discharge, and screw extrusion. All parts of the cylinder and agitator that come into contact with the material are made of SUS304 stainless steel, ensuring product quality.
