Product Description

Sand drying machine is also known as Sand dryer, sand rotary dryer. Sand dryer is a kind of material handling a large dryer. Due to the reliable operation, simple operation, strong adaptability, large capacity, energy saving and environmental protection, small investment, quick effect, widely used in building materials, chemical, foundry, wall insulation, etc., can adapt various fuels, such as coal, oil, gas, and so.

Feature

1, Equipment investment is wind foreign imports by 20%, manganese wear-resistant plate manufacturing, than ordinary steel wear 3-4 times.

the initial moisture content of 15%, final moisture to ensure that 0.5-1% is the following, is a cement plant slag powder, dry and wet mortar production line and other kinds of drying engineering preferred products.

Wheeled cement kiln (cement kiln) for preparing dry and wet clinker.

Rotary Kiln (Mining Chemistry): Magnetization and Oxidation of Roasted Iron Ore in Steel Plants

Wheel kilns use high-strength aluminum ore for roasting in plant smelting.

Rotary kilns used in aluminum alloy barbecue factories, chrome plated barbecue factories in chemical factories, and powder factories.

Rotary kilns (lime kilns) are used for active calcification of lime and dolomite in steel and ferroalloy plants.

Working principle

The sand is transported to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe through the feeding machine of the hopper. The slope of the feeding pipeline should be greater than the natural inclination angle of the material, so that the material can smoothly flow into the sand dryer (yellow sand dryer). The dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, forming a countercurrent contact with the material. There are also heat carriers and materials flowing together into the cylinder. As the cylinder rotates, the material moves to the lower end under the action of gravity. During the forward movement of the wet material in the cylinder, it directly or indirectly receives heat from the heat carrier, allowing the wet material to dry and then be sent out through a belt conveyor or screw conveyor at the discharge end. There is a board installed on the inner wall of the sand dryer (yellow sand dryer), which is used to pick up and scatter materials, increasing the contact surface between the materials and the airflow, in order to improve the drying rate and promote the material's progress. Heat carriers are generally divided into hot air, flue gas, etc. After the heat carrier passes through the dryer, a cyclone dust collector is generally required to capture the materials carried in the gas. If it is necessary to further reduce the dust content of exhaust gas, it should also be discharged after passing through a bag filter or wet dust collector.
