Powder Storage and Automatic Batching System
Product Introduction
The automatic level of storage and batching method of the powder raw material is related to the production control, output efficiency and product quality degree. The improvement of batching automation level will make a great contribution to the industry production efficiency of the related fields. The Powder Storage and Automatic Batching System that Siehe Industry design and manufacture is widely used in industries such as food, medicine, chemical, coating, ink, building material, etc., it has greatly improved the production efficiency. On one hand, the high degree of automation solves the weakness of low precision, unstable quality and poor statistical management of the artificial batching before, at the same time, it has realized the database management and network management, it can connect to the factory management network and transmit the production data in real time to plant management network, thus achieve the functions of data backup, query, statistics, printing, it has greatly improved the management level of the factory; On the other hand, optimizing process and improving the control of precision and mode of the process during the production is the most effective means to improve product yield and quality, it is also the most direct way to reduce the enterprise production cost and strengthen the key competitiveness of the products.

Product Advantages
Various batching ways
Batching ways, in general, can be divided into weight gain and weight loss method; Batching by weight gain method is with high precision and low cost; And batching by weight loss method has high efficiency and can also monitor the raw materials.
Various feeding methods
Commonly, feeding methods include single shaft screw conveyor, dual shaft screw conveyor, vibration feeder, belt conveyor, etc..
A high degree of automation
System can not only realize automatic batching, improve the control precision of the process, improve product quality and efficiency, but also achieve the database and network management(with recipe management, real-time batching report printing, formula production, raw material weight consumption report, and can calculate quantitative management reports about the duty, day, week, year, month, etc..), which greatly enhances the management level of the factory.
High quality of partner to ensure the stability of the system
Siehe Industry procure global well-known companies of high quality products, which ensure the batching accuracy and system stability: weighing instrument - Mettler Toledo, material level meter - VEGA, pneumatic components-Festo, frequency converter - Emerson, touch screen - Siemens, PLC- Siemens and so on.
Working Principle
Automatic batching system is mainly composed of batching transportation equipment, weighing body, high precision weighing sensors, weighing display controller, industrial control machine, frequency converter, electric control cabinet, process simulation screen and other parts.
Batching methods divided into weight gain method and weight loss method:
Weight gain method: Raw material silo is equipped with high and low material level meter (high level alarm stop feeding and low level alarm for materials feeding), with 1 or more weighing hoppers (according to the batching quantity and batching precision),. Firstly, quickly feed to the hopper to the value close to the required value, stop. Then slow feeding device continue to feed, when gradually close to the batching quantity, considering the suspension amount, fine feeding device gradually slowing down in advance to stop, and immediately close off the valve to stop the possibility of materials collapse. The instrument tracks the feeding quantity, after fine feeding device stopped, delay Δt for seconds until it is stationary and instrument displays stable value. This is the batching for the first raw materials, then go to the second raw materials same process as the first one. The process repeats until all materials are batched.
Weight loss method: Each raw material silo is equipped with weighing module, it can display material quantity of raw material silo, raw material can be synchronously batched, so it is with high efficiency; For batching process, first, quickly feed to the intermediate hopper or mixer, when feeding close to set lower limit of the weighing instrument, fast feeding stops, fine feed continue to feed and shut down automatically when set value is reached.
