Introduction

PWF/R Series Spoke Rotor Powder Quantative Feeding System is mainly used for constant feed and control of kiln feed raw meal in cement production, and constant feeding and metering of powdery materials such as fly ash and slag powder with advanced technology, accurate metering, stable operation and convenient maintenance.

Technical indexes

• Applicable material: material with size less than 2mm, such as slag powder, fly ash ,carbide slag powder and cement powder.

• Moisture: <5%

• Feeding capacity: 3.0≤180m3/h

• Metering accuracy: ≤ ±0.5%

• Adjusting range: ≤±1.0%

• Adjusting range: 1:10

Characteristics

1. It directly measures material weight inside the rotor, whose metering accuracy is accurate and will not be influenced by material property, air flow and material flow properties.

2. Its bearing sealing prejudging technology and rotor suspended construction can ensure a long service life; within 5 years, there will be hardly any wearing parts.

3. It's of heavy duty adjustable suspension structure, with high weighing sensitivity whose real-time regulation is possible.

4. It adopts the predictive control technology, which saves in the control system the rotor load and its angular displacement at any time. Before the material is discharged, the angular speed during material discharging is calculated on the basis of the system set flow rate and rotor load. In controlling the speed of frequency variable motor, we can realize the quantitative feeding. The technology is advanced, with stable feeding.

5. It's of simple structure and full-sealing design. Inside, there's only a low speed rotor running, with easy operation, reliable running and no leaking.

6. It adopts spoke rotor, and the material freely falls during system running. During the rotor rotation, the material fluctuation and filling rate variation are small; the material feeding is uniform and stable.

7. According to the special process and the material properties, we adopt different pre-feeding device and implement pre-feeding+ predictive control technology (double loop control), ensuring continuous and stable feeding with high metering accuracy.

8. With special design of long service life, the system has a long service life, a low default rate and easy maintenance.

Utilization

Mainly suitable for constant coal feeding of industrial kilns in building materials, metallurgy, power, nonferrous metal and chemical industries, also for constant coal feeding of other powdery fuels such as petroleum coke powder.

1. Constant coal feeding of the rotary kiln and calciner for cement production in the building material industry.

2. Constant coal feeding of rotary kilns for aluminum oxide, magnesium oxide and zinc oxide burning in the non-ferrous metallurgy industry.

3. Constant coal feeding of rotary kilns for pellet, lean iron ore magnetization burning and ferronickle smelting in the ferrous metallurgy industry.

4. Constant coal feeding of rotary kilns for soda, phosphate fertilizer and barium sulfide burning in the chemical industry.

5. Constant coal feeding of waste heat power generation boilers.

6. Constant coal feeding of raw material burning rotary kiln for refractory material production.

7. Constant coal feeding of lime, carbon and fine ceramsity kilns in other industries.
