Single drum industrial Sand dryer Machine,slag dryer,frac sand dryer

Brief Introduction

Cylinder capacity: :9-285m³

Processing capacity: 1.9-76t/h

Material processed: mineral powder, slag, clay, limestone, fly ash, coal powder, lignite, sawdust, oil palm fiber, grass, river stone, poultry dung, ores, rock sand and other materials.

Application: mainly used for drying materials with some moisture and granularity

Application Area: mining, ore beneficiation, building material, metallurgy, chemical department, etc.

Working Principle

1. The heat source of the drum dryer comes from the combustion device and this dryer uses co-current heating method, so that when the materials to be dried go into the cylinder from the feeding box or feeding chute, they are pushed back by the spiral lifting board.

2. Since the drum dryer is obliquely installed, the materials flow to the lower end of the machine under the gravity and the rotation of the machine, and on the other hand, the materials are repeatedly lifted by the lifting board to the higher end and then spread down constantly, so that the materials will form a even curtain inside the cylinder and conduct heat exchange with the hot air inside the cylinder. Since the materials constantly spread and the water contained in them will be dried, thus achieving the aim of drying.

Features

1) This machine uses reasonable running parameters, and the coal and electricity consumption is reduced by over 10-15% and the output per machine is improved by over 10-15%.

2) It has high adaptability to the materials so that it can be used for drying all kinds of materials.

3) The product moisture can be controlled according to user requirements

4) the dryer can change operating parameters according to different material properties, with high quality and sufficient heat exchange;

5) the dryer adopts new feeding and discharging devices, putting an end to feeding jam, discontinuity, non-uniform phenomenons of vertical dryer, reducing the load of dust-removing system;

6) the dryer achieves "zero horizontal thrust", greatly reducing the wear of gear wheel;
the dryer adopts self-aligning roller device, wheel and roller ring contact each other in a line, thereby greatly reducing wear and power loss
