Introduction

The system, specially used for pulverized coal metering and quantitative feeding control, is composed of annular balance rotor scale, FR multi-layer steady flow feeder and SP air locking conveying pump. The FR multi-layer feeder is used for ensuring material homogenization, annular balance rotor scale for accurate measurement and SP air locking conveying pump for air locking and conveying during pneumatic conveying. The system, equipped with special PLC control system for a coordination control on different equipment, is applied mainly for pulverized coal quantitative control in coal supply system of industrial kiln.

Technical indexes

• Applicable material: pulverized coal
  

• Moisture: <4%

• Coal feeding capacity: 0.5～15t/h

• Metering accuracy: ≤ ±0.5%

• Control accuracy: ≤ ±1.0%

• Adjusting range: 1:10

Characteristics

1. The powder feeder, with a multi-layer sealing construction and a big diameter, adopts predictive control technology, which is in favor of the material falling inside the bin. The multi-layer sealing construction can ensure the continuous and stable feeding of powder material and effectively avoid material surging and arching.

2. As metering device, the annular balance rotor scale is the balance type weighing structure, having sensor direct bearing force, without lever and balance weight, with high sensitivity and accuracy, high metering accuracy and reliable operation. The external factors such as air flow and impact force from falling materials will not cause the zero drift of balance body

3. The unique special air locking conveying device can effectively ensure the continuity and uniformity of conveying material.

4. The system introduces the earlier feedback plus double-annular closed circuit adjusting mode, with high response speed and high operation stability.

5. The system uses the modular design with simple maintenance, high reliability, simple replacement for flexible seal and low use cost.
