Intensive mixer is an ideal equipment for kneading, blending, vulcanizing, and polymerizing high-viscosity, elastoplastic materials. It is used in the production of silicone rubber, sealant, thermoplastic adhesive, food gum base, and more. The intensive mixer is a mixing and stirring device, commonly featuring two Sigma blades arranged in parallel, with one blade rotating at a higher speed than the other to generate shearing force. The different blade speeds allow the blended materials to be quickly sheared, ensuring uniform mixing.
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 generally composed of several major components, including the kneading system, vacuum system, heating system, cooling system, and electrical control system.
The kneader generates a strong shearing action through a pair of interlocking and rotating Σ blades, which rapidly reacts with semi-dry or rubbery, thick plastic materials to achieve uniform mixing and blending.
The kneader is primarily composed of five main 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 cylinder for opening and closing functions. It also uses a hydraulic station to control the cylinder for functions such as tilting and opening. Detailed parameters can be freely selected and required by the user, offering convenient and reliable operation. The transmission system consists of an electric motor, a reducer, and gears, which are matched with the motor according to the kneader 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 fast mixer by the output unit to reach the specified speed. It can also be adjusted using a variable frequency drive.
The kneader features two sigma-shaped blades, with different speeds for each blade, which can be set to various rotations per minute based on different processes. The common rotation rates are 42/28 rpm.
Mixers can be designed in both heated and non-heated versions based on requirements. Heat exchange methods typically include: electric heating, steam heating, recirculating hot oil heating, and recirculating water cooling.
The kneading machine has discharge methods such as hydraulic tilting, ball valve discharge, and screw extrusion. The cylinder and paddle parts in contact with the material are all made of SUS304 stainless steel, ensuring product quality.
