Gravimetric blender

What is a gravimetric blender？

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). So as to solve the problems of manual weighing errors and uneven mixing in production, and improve product quality!
Gravimetric batch blender type：
Loss in weight gravimetric blender
This type of gravimetric blender measures the "loss in weight" from two or more hoppers using a load cell under each hopper. Material is usually dispensed from the hoppers using a screw conveyor. All materials are dispensed together and the rate of dosing from each hopper is controlled to ensure the correct blend is achieved.
Gain in weight gravimetric blender(sometimes called a batch blender)
A gain in weight gravimetric blender has two or more hoppers arranged above a weigh-pan. These hoppers contain the components which are to be mixed, at the base of each hopper there is a valve to control the dispensing of material from the component hopper into the weigh-pan. The components are dispensed one at a time into the weigh pan until the target or batch weight is reached. Once the batch has been weighed out the contents of the weigh-pan are dispensed into a mixing chamber where they are blended. The resulting mixture exits the base of the mixing chamber into the processing machine.
A typical application of a gravimetric blender would be mixing virgin plastic granules, recycled plastic, and masterbatch (an additive used to colour plastics) together. .

Operation and working principle of gravimetric blender

The gravimetric blender is based on PLC control and is an automated equipment that completes the uniform mixing of multiple or multiple raw materials. First, set the formula ratio of each ingredient on the touch screen console of the gravimetric blender. When various raw materials enter the upper hopper, there is a weighing platform below the hopper to weigh the raw materials, and then the weighing data is transmitted to the console. When the hopper raw material weighing count value is the same as the ratio set by the console, the hopper feeding system is closed, the valve at the bottom of the hopper automatically opens, all the hopper raw materials enter the mixing tank, and the mixing tank mixing system automatically opens; when all the raw materials enter the mixing tank . The valve at the bottom of the hopper is closed, and the feeding system at the top of the hopper is opened. According to the mixing system time set by the console, the weighed various raw materials are fully stirred in the mixing tank. When the mixing system reaches the time set by the console, the mixing is completed, the valve at the bottom of the mixing tank is automatically opened, the mixed raw materials are automatically output, and the next production cycle is entered!

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. In the production workshop of the enterprise, we use more reasonable equipment installation and equipment connection, and adopt "Internet of Things" and "4.0 Industry" design solutions to save costs and save factory space. We use multiple hoppers, powder meters or granules in one machine. The instrument can better solve the problem of uniform ingredients. A multi-distribution sealed distribution method is adopted to ensure that the workshop and equipment are not contaminated by dust, and at the same time extend the service life of the weighing mixer and the environmental protection and product quality of the workshop.

Gravimetric blender technology and installation solutions

How to let the gravimetric blender solve the problem for the enterprise is the key. Energy saving, environmental protection, time saving, automation and intelligence, the installation of gravimetric blenders for enterprises will bring long-term value to enterprises. This is why we have been developing gravimetric mixers and gravimetric mixers. Therefore, we tested many ways to change this technology. For example, according to the different raw materials, we will use a gravimetric blender for weight reduction, weighing, liquid and other measurement methods. The mixing is also based on the testing of various raw materials; in the mixing screw and double blades, the mixing is more uniform, and the particles and micro particles are evenly mixed, and the density characteristics of the raw materials are used to formulate corresponding technical solutions! We have our own R&D capabilities, manufacturers and developers, and have patents for gravimetric blenders and software program certificates.
Thousands of successful cases, including Toyota, Honda, Foxconn and other well-known companies, only technology + installation can better formulate corresponding solutions, so we also have higher technical requirements for installation to save company funds and company space ，In production, this is a gravimetric blender, which can mix multiple raw materials, and automatically provide the blended raw materials to multiple machines at the same time according to the company's needs. This requires a good solution to complete.
For example, factory size and production materials. Only through the displacement, conveying distance, energy consumption and other related data of the machine, we can provide the corresponding gravity model and installation rule design of the gravity mixer, so as to reasonably save more funds and space occupied. And provide the company with better solutions to save money, save company space, energy saving, environmental protection, time saving, labor saving, automation, intelligence and solutions with long-term value.
