Quantitative feeder scale

The speed regulating quantitative feeder scale is a product continuously improved and optimized by Fest based on the digestion, absorption, and introduction of Shenke, combined with long-term practice and experience. Years of practical application have proven that this equipment is reliable in quality, stable in performance, and accurate in measurement. It is suitable for continuous dynamic measurement and quantitative feeding of bulk, block, and powder materials, and is widely used in industries such as building materials, metallurgy, chemical engineering, coal, ceramics, food, tobacco, and medicine.

Variable speed quantitative feeder scale, widely used in cement and mining industries, especially suitable for mill batching and feeding control DEL/DEM quantitative feeding belt scale - control process:

The host adopts a standard industrial control host, and the IPC-810a (Advantech) has reliable performance; The ingredient metering control can be divided into two groups of 16 weighing scales simultaneously (such as two grinding machines). And it has formula calculation, automatic ingredient input, multi page display, and automatic online reminders. It can easily form a distributed control system (DCS) with the upper computer.

Quantitative feeder scale - structural features:

1. Integrated direct connected reduction motor, manufactured with imported technology from abroad, with low noise, low vibration, dust resistance, long life, and high reliability; 2. Circular seamless belt, conveying methods can be selected according to the site: flat belt, baffle structure, skirt belt structure;

3. The scale body frame is composed of cold-formed C-shaped steel plates, with a novel structure and high strength, suitable for the design of various non-standard scale bodies;

4. The unique X-shaped spring weighing mechanism ensures more uniform force distribution on the spring, with better linearity and repeatability;

5. The deceleration motor is equipped with a reverse torque support plate and a shaft mounted structure. Directly connected to the active drum of the scale body, installation, debugging, and maintenance are extremely convenient.

6. The design of the weak magnetic gear speed measurement device, combined with the speed measurement circuit, truly reflects the motor speed, and the speed measurement signal is accurate and reliable

7. Unique belt anti deviation device, imitating the three roller structure of Shenke scale, can freely adjust the tension roller;

8. The feeding device of the scale body comes with a pallet, which can easily control the feeding amount and sealing material for the calibration and zeroing of the scale body;

Quantitative feeder scale - principle:

The load and speed signals of the conveyor belt are transmitted to the measurement, control, and adjustment system controlled by a microprocessor for processing. The actual feed rate is continuously compared with the set feed rate to control the speed of the conveyor belt and maintain the feed rate at a constant level.

Quantitative feeding belt scale - System features:

A high-resolution weighing sensor with a minimum displacement of 0.1 millimeters ensures accurate measurement values.

High resolution digital pulse speed sensor ensures accurate speed values are obtained.

Gravity automatic tensioning device ensures constant belt tension, avoiding belt slippage and excessive tension.

The automatic belt correction device prevents production from being affected by belt deviation.

The pear shaped scraper clears the debris on the lower belt to one side, avoiding damage to the belt caused by debris between the belt and the roller surface.

Scrapers on both the inside and outside of the belt are used to prevent material sticking and changes in tare weight.

No need for assistance, belt replacement is convenient and maintenance is simplified.

The main and auxiliary rollers are equipped with automatic self-aligning bearings, making installation and adjustment very convenient.

Quantitative feeding belt scale - Main technical parameters:

1. The actual feeding accuracy of various bulk materials is better than the feeding rate set at ± 0.5%.

2. The feeding rate is approximately 50kg/h-2000t/h.

3. Transport bandwidth 500mm-1800mm.

4. The center distance of the roller is 1000-8000mm, using a plug-in system, and the size can be customized according to user requirements.

5. Output interface: Multiple options available, can be connected to DCS system.

6. Environmental temperature: Scale body -10 ℃~+60 ℃ Instrument -10 ℃~+45 ℃.

7. Working power supply: Instrument AC220V ± 15% 50Hz ± 2% Scale body AC380V ± 15% 50Hz ± 2%.
