What Is a Quantitative Feeding Device?
A quantitative feeding device is a device that is capable of continuously feeding a set amount of material.
The material can be a powder or a liquid, and the cut-out part, which cuts out a fixed amount, can be a single-shaft type or a screw type.
The simple structure makes maintenance work such as cleaning and inspection easy.
Uses of Quantitative Feeding Devices
Because they can continuously feed a fixed amount of material, quantitative feeding devices are used in fields such as raw material feeding, quantitative feeding in production and processing lines, and R&D devices in universities and research institutes.
They are also used in the production of food and medicine, fuel, and waste disposal. For example, food and pharmaceutical plants supply raw material powders during the manufacturing process. Fuel facilities supply a certain amount of auxiliary fuel, and incineration facilities supply chemicals and slurry.
Since there are multiple feed ports for a single storage silo, it is important to select the appropriate quantitative feeding device for the application.
Principle of Quantitative Feeding Devices
A quantitative feeding device consists of a silo for storing raw materials, a feeding panel for measuring the feeding volume, and a chute for feeding raw materials.
The flow of material until it is fed is as follows: material is stored in the silo at the center, agitated to make the density uniform to prevent errors in the feed rate, and discharged to the feed port after a certain feed rate has been met.
