Gravimetric blender:Low energy consumption gravimetric batch blender

What is a Gravimetric blender？

Gravimetric blender are used in injection molding and extrusion industries. In this industry, a variety of color masterbatch granules, plastic pellets and various powders need to be accurately Gravimetric in proportion, The Gravimetric batch blender can automatically perform gravimetric analysis in proportion to measure and mix one, two, three, four, five, six or more plastic particles or plastic powder raw materials. According to production needs, various materials can be evenly mixed in proportion to make new mixed raw materials,The measurement can be accurate to particles,and the Gravimetric and blending accuracy can reach ±0.1%.
Gravimetric blender a mechanical device that integrates weighing, metering and mixing functions, all use PLC controllers and advanced batching algorithms to ensure the high quality and comprehensive technical characteristics of this series of products, so that the products have excellent performance, stable operation, excellent production performance, automatic alarm and error correction function, safe and reliable comprehensive technical characteristics. Technology to solve manual weighing errors and uneven mixing in production.
Composition of Gravimetric blender：
The main components of the Gravimetric blender include hoppers, racks, weighing instruments, mixing barrels, PLC consoles, electric boxes, motors and other components.
Gravimetric batch blender running:
When the raw materials are transported to each hopper, each hopper is equipped with a weighing instrument. When each raw material enters the mixing tank, the weighing instrument will weigh and measure the raw materials according to the proportion set on the control platform. When the weight of the weighing instrument matches the proportional parameter set by the PLC console, the valve under the hopper opens and then enters the mixing tank for raw material processing. High-speed impact and dispersion can achieve rapid mixing, dispersion and refinement of functional and efficient equipment. After reaching a uniform mixing time, the PLC control program will automatically open the material valve under the mixing barrel and automatically output the mixture at the speed set by the PLC console.
Gravimetric batch blender type：
Loss in weight
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 (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) togethe
Especially in the medical and environmental protection industries, the machinery will fully adopt food stainless steel materials and fully enclosed feeding and discharging to avoid external pollution.[More Gravimetric blender information]

Type of gravimetric blenderThe maximum throughput and mixing ratio error data are based on the bulk density with a diameter of 0.1kg/L. The data will vary according to the characteristics of the raw materials!
Each model has an automatic alarm system and automatic error correction function.
The hourly conveying capacity of each unit and each raw material can be customized, and related hoppers can be added or removed

Model Equipment	Brief Introduction of Equipment	Industry application
	This is a gravimetric blender for mixing plastic particles and masterbatch particles. It can be combined into multiple hoppers at the same time to realize automatic metering and stirring of more than 1, 2, 3, 4, 5, and 6 kinds of raw materials; to obtain a new type of mixed raw materials. Realize the mixed raw materials required for factory production. It is controlled by PLC and can be customized according to the company's requirements. Counting system; the gravimetric accuracy of the system can reach particles. Using spiral stirring, the blending speed and output speed can be controlled. [More Gravimetric blender information]	Mainly used in injection molding and extrusion industries, but also in the ceramic industry. For plastic particles or masterbatch particles, the weighing system is accurate and even mixing, but it is not suitable for weighing and mixing powdered materials.
	This is a twin screw gravimetric blender. It can combine one,two,three,four,five,six,or more plastic particles and master batches at the same time, automatically measure and automatically blending these raw materials. Obtain a uniformly mixed mixture for production. In the mixing, each system is air-tight. 304 food steel is used to reduce the pollution of raw materials or workshops, and the weighing accuracy of the system is higher. It adopts two-way spiral stirring, the stirring speed is fast, and the PLC controls the stirring speed and output speed. customizable [More Gravimetric blender information]	It is mainly used in automated production systems that have higher requirements for medical treatment or the environment. For example, in medical precision equipment, automotive precision parts and other industries, weighing, metering and mixing are all sealed to reduce the infection of air or raw materials in the workshop.
	This is a gravimetric blender directly connected to the injection molding machine. It can weigh 1, 2, 3, 4, 5, 6 or more plastic particles and master batches at the same time for automatic measurement and automatic mixing. It can be Closed or semi-closed, with higher weighing accuracy, double spiral or single spiral stirring can be used, PLC controls the stirring speed and output speed, production needs to be customized, installation is simpler, and space saving [More Gravimetric blender information]	It is mainly used in the injection molding industry and the standard "4.0" automated production system. It can automatically weigh, measure and mix plastic granular materials (such as PET, PC, master batches and other plastic raw materials). Because it is a double mixing pair, it can also weigh and mix micro-particles, thus saving labor and electricity.

The multi-powder meter or particle meter can better solve the batching problem. When mixing, we use a special mixing barrel to mix plastic particles or plastic powder. Corresponding sealing systems have been developed to ensure that the workshop and equipment are not contaminated by dust. Extend the service life of the gravimetric blender, workshop environment and product quality.
