FB-CWLF loss in weight feeder, PLC+HMI or intelligent instrument, Patented product, High precision, ISO9001:2008 quality system - details see: https://www.machineto.com/fb-cwlf-loss-in-weight-feeder-10199526

FB-CWLF loss in weight feeder

Product Introduction:
High quality FB-CWLF 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 inpower, pharmaceutical, food, chemicals and building materials industriesas the measurement equipment forpowder material, granule material and bulk material,givingprecise measurement and continuous feeding controlto 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.

Structure Features:
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 untomatic air blow,which made material formrotational 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 précised sensors are mounted on the weighing bin and distributed at 120°C 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.

Production 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 wll 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 presing;

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 outpur 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 computor, PLC or DCS through the instrument and communication interface. It is very stable and reliable;
