We are offering continuous loss in weight feeder. Introduction:fb continuous loss-in-weight feeder, short for loss in weight feeder, is a continuous feeding device to measure the material flow by the decrease rate of material in unit time. As measuring flow rate in an approximately static weighing method, it is simple, high precision and practical. It is widely used in power, pharmaceutical, food, chemicals and building materials industries as the measurement equipment for powder material, granule material and bulk material, giving precise measurement and continuous feeding control to the various components of the material. the control system adopts plc + hmi or intelligent instrument which is very easy to operate and is stable and reliable. It can display state of the feeder and also have friendly human-computer interaction interface. features:1.with simple and reliable structure design which prevent material impact during feeding efficiently and ensure excellent material flow inside the storage bin and short re-feeding time and also ensure transmission system operate well and in good linear;2.suitable material: non-cohesive powder and solid granule;3.accurate continuous feeding;4.full discharge without residue, easy and simple to clean;5.easy to stall and operate;6.high feeding precision;7.widely measuring control range;8.the control system can be plc control or dynamic control instrument, which can set flow rate and operation mode, indicate total accumulation, instantaneous flow rate and output as well as other parameters for complete feeding and discharge control and also can indicate working state and alarm;9.the control system is in modular design and can be connected to upper computer, plc or dcs through the instrument andcommunication interface. It is very stable and reliable structure:1.the loss-in-weight feeder is composed of assist flow storehouse, manual valve, two pneumatic valve, surge bin, flexibleconnection, weighing bin, load cell, mixing device and screw conveyor. 2.assist flow storehouse: adopting automatic air blow, which made material form rotational flow, preventing phenomenon of blockage and flow material;3.surge bin: two imported phenomenon valve act as upper and lower joint parts, which can ensure the material absolutely sealing, in this case, the material will never flow to weighing bin, thus keep a high accuracy;4.weighing bin: the weighing bin is designed for weighing and able to prevent bridge and material impact and also ensure smooth and well-distributed feeding; meanwhile, it is easy to dismantle during cleaning and replacing of some parts and components. The volume of the material bin depends on the feeding capacity. 5.load cell: three highly prcised sensors are mounted on the weighing bin and distributed at 120c ensuring the weighingaccuracy. 6.mixing device: to prevent bridging and ensure smooth and well-distributed feeding, its main structure is that add mixingactivation device on top of the weighing bin with horizontal motor and reducer inside to drive vanes for mixing. 7.screw conveyor: high accuracy screw is used, allowing a small spacing between the screw and shell after precision processing, thus ensuring high weighing and measuring precision and stable feeding. The motor and reducer is connected directly to shaft of the screw blade which reduce the transitional steps so as to ensure high weighing accuracy. 8.all parts that contacting material are made of stainless steel, which can improve the fluidity of material and also can improve service life.

We are offering weigh feeder. perfect informatization weigh feeder system for granular and lump material introduction:informatization weigh feeder system is a set of complete system equipment for continuous conveying, dynamic weighing and feeding control of granular and lump material on real-time. Informatization weigh feeder is a new generation intelligent product of traditional weigh feeder, which applies modern information technology to automation control system to realize the continuous weighing and control of granular material and bulk material. The control system has the characteristic of high degree informatization and can achieve production modernization and comprehensive production management through humanized operation. features:1. With the functions of message notification and alarm, and can bind more than one user's mobile phone numbers( such as directors and professional engineers, etc.) anywhere at any time. 2. Commissioning and calibration adopts wireless hand-held equipment with friendly interface and easy operation. 3. Weight feeder connected with dcs and the frequency converter through 485 bus. Using modbus communication protocol makes the connection simple. 4. For weighing and measurement, it adopts double load cell and direct gravimetric structure with the characteristics of simple structure, easy to install, easy to maintenance. 5. For mechanical structure, the design is more flexible. 6. The feeder has been equipped with automatic compensation cleaner to avoid the trouble of manual adjustment after the wear of the cleaner. 7. Professor of the control system adopts 32 bit arm chip, can greatly improve measurement accuracy and control precision. 8. Touch-screen human-computer interface is user-friendly, so user can operate the weigh feeder without remembering lots of parameter codes so as to save the training cost. application fields: all continuously operated processes e.g. Mill feeding products: fine, coarse and sticky materials such as limestone, gypsum, clay, clinker, iron ore, coal, coke, pellets, additives etc. dosing capacity: 11000t/h features: 1.stable material dosing 2.
