Problems solved by technology

When processing this kind of feed, it needs to go through processes such as stirring and granulation. The current granulation equipment is mostly a single-screw internal mixer for processing organic powder such as plastics. This machine uses a single-screw rotation to continuously squeeze the mixture. out of the machine head, but the pressure of single-screw rotation is limited. When processing metal powder, it cannot provide enough pressure, which slows down the processing speed and reduces the production efficiency.

Abstract

The invention discloses a double-screw pelletizer based on inorganic powder. The double-screw pelletizer comprises a machine body, an operation panel, a double-screw material squeezing device and a particle cutting device, wherein the operation panel is fixed on one side of the position above the machine body, the double-screw material squeezing device is located in the middle of the machine body, and the particle cutting device is located on the other side of the machine body; the double-screw material squeezing device is composed of a material chamber, double screws, a motor and a double-shaft distribution gear box; the double screws are horizontally arranged in the material chamber, and the double-shaft distribution gear box is connected with the motor and the double screws; when the double-screw pelletizer works, the double screws rotate to squeeze materials out of the material chamber so that the materials can make contact with a particle cutter rotating rapidly, the mixed materials are cut into particles through the particle cutter, and meanwhile processing is completed after cooling and shaping are conducted. The double-screw pelletizer has the advantages of being high in particle cutting speed, high in efficiency and the like.

Description

technical field [0001] The invention relates to raw material processing equipment of powder injection molding technology, in particular to a twin-screw granulator based on inorganic powder, which can perform granulation, cooling and shaping of the stirred mixture. Background technique [0002] The processing raw material of powder injection molding technology is a special feed made of metal powder after stirring and mixing. When processing this kind of feed, it needs to go through processes such as stirring and granulation. The current granulation equipment is mostly a single-screw internal mixer for processing organic powder such as plastics. This machine uses a single-screw rotation to continuously squeeze the mixture. out of the machine head, but the pressure of the single screw rotation is limited. When processing metal powder, it cannot provide enough pressure, which slows down the processing speed and reduces the production efficiency. Contents of the invention [0...
