Loss In Weight Feeder Suppliers and Manufacturers

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 and communication 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, flexible connection, 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 pr¨¦cised sensors are mounted on the weighing bin and distributed at 120¡ãC ensuring the weighing accuracy. 6.Mixing device: to prevent bridging and ensure smooth and well-distributed feeding, its main structure is that add mixing activation 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. Parameters: Ambient temperature: -20C~100C Working voltage: AC380V 50Hz Measuring Accuracy: 0.5% Material moisture: 2% Feeding speed: 0.03t/h~300t/h Communication interface: RS485, Mod-bus wooden case

Application Liquid loss-in-weight feeder is designed to provide gravimetric feeding of liquid materials.It is most frequently applied in continuous processes,such as feeding a compounding extruder where difficult flowing liquids must be metered at precise feed rates. These liquids are often waxy or viscous and must be heated to flow properly. Characteristics ¡ï consists of a storage tank mounted on a high accuracy scale designed for industrial applications. ¡ï The liquid is metered by a pump positioned off the scale so that only the liquid and its container are weighed. ¡ïIf the temperature of the liquid to be fed must be maintained at a constant level, a strip heater or transfer heater using oil or water may be employed. ¡ï When using a strip heater, temperature is controlled by a thermostat and a safety thermostat. An insulating jacket is placed over the strip heater. The connecting line is also heated and thermally insulated. ¡ï When using heat transfer, the tank is double-walled and filled with oil or water. ¡ï The sophisticated load cell provides split-second, high precision weighing in the milligram range and is specially designed for harsh industrial environments. ¡ï Liquid feeders are easily integrated with gravimetric bulk solids feeders. The gravimetric controller and operation interface allow for individual unit and recipe control. Each feeder has its own control board. Connection between control boards and operation interface is supported by industrial protocol. Plywood case, 1 set/case

BATTE is a professional designer of equipments in the world, its loss-in-weight metering systems with high accuracy can totally satisfy the fields of pharmaceutical industry, chemical industry, food, rubber and so on. Intelligent controller High accuracy Advantages: 1. Generous and beautiful appearance: Comparing with traditional feeders, BATTE does more improvements on feeders' appearance. 2. Small volume: Easy to move, more suitable for changing and improving production process. 3. Low noise: Comparing with others, noise of BATTE's feeders is up to perfect. 4. Easy to clean and maintain: It's easy to maintain in operation, meanwhile, very short maintenance time. Especially the control systems, adopting the leading software and hardware, are nearly free-maintenance and long-service life. 5. High stability: BATTE adds self-detection function when designing its feeders for more accuracy, it allows to detect attritions of parts and frequency variation timely, then revise them. That avoids the influences owing to replacement of parts and longtime usage. So BATTE's feeders own high stability. 6. The touch screen output and input system is humanity and easy to operate. As long as the operator has certain cultural foundation, he can master it within hours. So short train-time is needed. 7. Wide measuring range: Without replacement of parts, you can set wide range flow and realize the conversion of produce process smoothly. 8. Excellent control system: One control system can control multi-feeders according to clients' requirements. This won't affect the accuracy.

Applications When the bulk density of the fed material is not consistent, or when the precise feeding accuracy is critical to the end product quality, the loss-in-weight feeder needs to be used. The loss-in-weight feeder can be used in batch or continuous situations. Frequently it is applied in continuous processing, such as extrusion. During extrusion process, multiple ingredients` ratio needs to be controlled precisely.
