Sand Dryer

Rotary Sand Dryer is specially designed for drying all kinds of sand such as river sand, yellow sand, Silica sand, quartz sand, etc After being dried, the sand moisture content can be reduced to less than 1% or even bone dry With the features of high drying ability, low energy consumption, easy maintenance and operation, compact structure and less land occuptation, etc

Technical Parameters

Introduction of Sand Dryer :

◆ Widely used for drying all kinds of sand such as river sand, yellow sand, silica sand, quartz sand, pomegranate sand, etc.

◆ Mainly consists of rotary drum, carrier roller, lifting boards, large ring, large gear, inlet cover, outlet cover, inner lifting plates, motor & reducer, large steel support frame, etc.

Features of Rotary Sand Dryer :

◆ 7 Inner chambers & Triple Pass Design:

Longer drying time and efficiency;

◆ High Temperature & Quick Drying Method:

Inner temperature is 400℃-500℃, discharging temperature <= 80 ℃;

◆ More Durable:

Made of wear resistant manganese plate, 3 to 4 times more hardwearing than ordinary steel plate ;

◆ Less Fuel Consumption:

1/3 of the traditional drum dryer's fuel consumption, electricity power saving 40%, standard fuel consumption per ton dried sand < 1

Sand Dryer Working Principle and Workflow:

It is to use high temperature air to heat and dry the wet sand strongly, continuously and quickly for bulk production.

Sand dryer, drying sand machine, rotary drum sand dryer

◆ Belt Conveyor feeds the wet sand into the hopper which is on the top of sand dryer.

◆ Burner & Hot air furnace supply the hot air for the sand dryer.

◆ Inside the sand dryer's cylinder, there are many flights, and these flights mix the wet sand and hot air sufficiently. The humidity in the wet sand is heated and evaporated into water vapour.

◆ At the end of the sand drying plant, there is one high pressure draft fan. Under the function of draft fan, the water vapour goes out of sand dryer in time.

◆ During the sand drying process, there is some dust mixed with the water vapour. In the cyclone separator, the dust is separated from the water vapour, and falls down.

◆ The dried sand goes out of the sand dryer machine from the outlet as product.

◆ Finally belt conveyor send the dry sand into silo or trucks.

Fuel Choice for Sand Dryer Machine:

◆ Biomass Fuel such as wood pellets, waste wood;

◆ CoaL;

◆ Diesel;

◆ Natural gas;

The users can choose the most economical fuel as actual need.
