Overview

River Sand Dryer Introduction

The river sand dryer is mainly used for drying particle materials with certain humidity. Due to advantages of strong production capacity, wide application, small flow resistance, easy to operate, river sand drying machine is often used to drying sand, river sand, slag, cinders, quartz sand, etc.

The river sand dryer can be equipped with gas furnace, combustion chamber or supporting hoist, belt conveyor, quantitative feeder, cyclone dust collector according to users' requirements.

River Sand Dryer Features

1. Accessories of the river sand dryer are wear resistant, with high thermal efficiency.
2. River sand dryer machine is applicable for white coal, bituminous coal, fuel, coal, oil, gas, etc.
3. Construction investment of it is low, and it's easy to be installed.
4. River sand dryer is with no leakage phenomenon, which can completely solve the sealing problems.
5. Discharge temperature is not higher than 60 degrees, directly feeding without cooling shed is OK.

River Sand Dryer Working Principle

Sand will be fed into the hopper through belt conveyor and bucket elevator, and then be fed into the end hopper through feeding machine or pipes. The inclination of feeding pipe should be larger than natural inclination of materials, for sand smoothly entering into the dryer. Dryer drum is a slightly inclined rotating cylinder with horizontal lines. Materials are fed from the higher end, while heat medium enters from low-end, forming counter-current contact with materials. Heat medium flowing into the cylinder together with material is available. As the rotation of the cylinder, materials run to the end of the sand dryer under gravity. Wet material, in the course of the cylinder moving forward, directly or indirectly get heat from medium heat, for drying wet material, and then discharged through the spiral conveyor or belt conveyor installed at the end of discharging port. River sand drying machine or river sand dryer machine is equipped with lifting board on the cylinder wall, and the lifting board plays the role of lifting and falling down materials, increasing the contact surface between material and air flow, so as to improve the drying rate. Heat medium is generally divided into hot air, flue gas and others.
