The gravimetric blender is to accurately mix various raw materials in proportion to obtain new and uniformly mixed raw materials required for production; it is mainly used in injection molding and extrusion industries.
The gravimetric blender is an automatic mechanical equipment integrating weighing, metering and mixing functions. Using PLC controller and advanced batching algorithm, it can automatically carry out weighing analysis, and measure and mix one, two, three, four, five, six or more kinds of particles or plastic powder raw materials according to the batching ratio. In order to obtain the new mixed raw materials required for production, the weighing and mixing accuracy can reach ±0.1% (even particles can be accurate to one particle unit). The gravimetric blender can store more than 100 sets of formulas, increase the storage capacity, and provide daily data reports；So as to solve the problems of manual weighing errors and uneven mixing in production, and improve product quality；Operation is very simple and easy to use.
Introduction to gravimetric blender types
Introduction to gravimetric blender types：
The gravimetric blender is mainly divided into two types: loss-in-weight gravimetric blender type and weighing gravimetric blender type;
According to the required mixing function of the mixed raw materials:
gravimetric blender types :Ball mill gravimetric blender、Drum type continuous gravimetric blender、Double pot gravimetric blender、Countercurrent gravimetric blender、Wheel spin gravimetric blender、Double-shaft blade gravimetric blender、Color Masterbatch gravimetric blender、Plastic pellet gravimetric blender, weighing gravimetric blender,Energy-saving gravimetric blender, standard gravimetric blender, loss-in-weight gravimetric blender.
According to the output per hour, it can be divided into: 10kg/hr(bl/hr)~4500kg/hr(bls/hr)

Application and design scheme of Gravimetric blender:
The gravimetric blender is suitable for mixing powder or granular materials in chemical, food, pharmaceutical, feed, ceramics, metallurgy and other industries.
Application of gravimetric blender in plastic granule
Input each color masterbatch into each hopper on the top of the weighing mixer, set the parameters in the console (control panel), and weigh and measure each color masterbatch to be accurate to the particle size and set the mixing time. Stirring is carried out, and then the materials are automatically output, and the weighing and mixing are completed. Will be automatically entered into another production device! These weighing, batching and mixing tasks will be completed automatically, calculated automatically by the computer, with an accuracy value of 0.01% or particles
Application of gravimetric blender Ceramic Enterprise Application of gravimetric blender in ceramic industry. The main raw materials of ceramics are powder and granules. We use multiple hoppers, powder gauges and particle gauges to better solve the batching problem. When mixing, we use a special mixing barrel to mix the agglomerated powder evenly with the particles. The mixing barrel mixes the powder and the particles together to make the ratio and mixing more uniform; due to the large amount of powder used There may be four types of raw materials and powders in the workshop. We will use the separation method of Gravimetric blender and workshop, and adopt pipeline transportation to ensure that the workshop and equipment are not polluted by powder, while extending the service life of the Gravimetric blender and the environmental protection of the workshop ,product quality.
Application of gravimetric blender in injection molding industry Application of Gravimetric blender in injection molding industry. The main plastic powders and granules in the injection molding industry. We use multiple hoppers, powder meter or particle meter to better solve the batching problem. When mixing, we use a special mixing barrel to mix plastic particles or plastic powder. The mixing barrel mixes the powder or granules together to make the ratio and mixing more uniform. The corresponding sealing system is formulated to ensure that the workshop and equipment are not polluted by dust, and at the same time extend the service life of the Gravimetric blender and the environmental protection and product quality of the workshop.
Application of gravimetric blender in extrusion industry
Application of gravimetric blender in extrusion industry. The main plastic powder and granule in the extrusion industry.
