rotary dryer coal burner, 1.for lime and cement plant, 2.large capacity, 3.various types, 4.whole set - details see: https://www.machineto.com/rotary-dryer-coal-burner-10293736

rotary dryer coal burner Introduction

rotary dryer coal burner is made up of Stove, Main Rotary Body, Screw Conveyor, Cyclone Separator, Air-lock, and Fan and matched Pipes which can realize to reduce the moisture from 60%-10%. The heat generator combined fan is not included in our quotation. Mainly used in building material, metallurgy, chemical plant, cement plant for drying of limestone slag, coal powder, slag, and clay stone. The dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation.

Working principle:

Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator. The barrel is installed with slope to horizontal line. Materials enter the barrel from the higher side, and hot air enters the barrel from the lower side, materials and hot air mix together. Materials go to the lower side by gravity when the barrel rotates. Lifters on the inner side of barrel lift materials up and down to make materials and hot air mix completely. So drying efficiency is improved.

rotary dryer coal burner features:

1.Wet materials are carried to the hopper by the Belt Conveyor or bucket elevator, then through the feeding pipe the materials are sent into the side.

2.Set feeding tube inclination angle in order to make the flow of material mooth. Dryer cylinder is located slightly in a slope.Materials are put in from the higher end , heat is sent in from the lower end.

3.With the rotation of the cylinder materials run to the lower end due to the force of gravity.

4.During moving forward in the cylinder ,the materials are dried directly or indirectly from the heat carrier, then sent out at the the discharge side by the belt conveyor or screw conveyor.

5.On the tube wall,there are boards to expand contact surface between materials and airflow ,so as to reduce drying time and to promote material progress.

6.Before releasing materials, reduce the dust content by the dust catcher.
