  About the introduction of gravimetric dosing and mixing units equipment

Principle of gravimetric dosing and mixing units

Input the color masterbatch or plastic raw materials into the hopper of the gravimetric dosing and mixing units, and then set the parameters, and set the feeding parameters of each color masterbatch to perform automatic weighing. After weighing, the hopper discharge valve automatically opens, and the raw materials enter the mixing tank after weighing. Stir

Equipment protection

Secondary filtration system, no pollution to the environment, protect the fan

Application of gravimetric dosing and mixing units

It is one of the necessary equipment for modern industry, pharmaceuticals, food, metallurgy, building materials, agricultural and sideline industries and other light and heavy industries. The vacuum suction machine can automatically transport various materials to packaging machines, injection molding machines, crushers and other equipment. In the hopper, the mixed materials can also be directly transported to the mixer (such as V-type mixer, two-dimensional mixer, three-dimensional mixer, etc.), which reduces the labor intensity of workers, solves the problem of dust overflow during feeding, and improves It improves work efficiency, accurate transportation, reliable quality and durability, and the raw materials are completely free from moisture, pollution, foreign matter, and loss during the feeding process. The feeding process is self-transported, avoiding the danger of high-altitude feeding and reducing labor. It is the preferred equipment for pharmaceutical factories and food factories to pass GMP certification and promote clean and civilized production.

The masterbatch mixer is suitable for the automatic mixing of new, secondary materials, masterbatch or additives. This series of models uses high-efficiency and energy-saving motors, mixes according to a preset ratio, and automatically converts to speed through the conditions set by the fully digital microcomputer control system, and drives the equipped precision screw to extrude the material. Add the required materials in the output (calendering) sol cylinder, such as: masterbatch, pigment, new material, additives, auxiliaries, etc. The error value is not higher than 1%. The product is divided into two modes, which are suitable for injection molding and extrusion molding. The screw diameter is divided into 6, 9, 12, 15, 18, etc., which can be evolved into a variety of models, providing different output capacities of 0.1-200 kg/h for customers to choose. There are also two-color, three-color and four-color masterbatch machines, which can be matched according to customer needs to meet different occasions and different fields.
It is widely used in the transportation of raw materials in various industries such as food, chemicals, pharmaceuticals, plastics, non-woven fabrics, chemical fibers, and graphite. It is perfectly matched with the hoppers of packaging machines, injection molding machines, shredders, mixers and other equipment.
It can mix 1 kind of pellet, 2 kinds of granules, 3 kinds of color masterbatches granules, 4 kinds of resin particles, 5 kinds of plastic pellets, 6 kinds of powders, 7 kinds of color masterbatches, and more plastic granules.
