Before the birth of three-drum sand dryer, people dry sand material with single-drum dryer. Owing to the reasons of low transfer efficiency and high heat loss, the single-drum dryer gradually falls into disuse. With regard to the sand rotary dryer, it performs relatively well in drying sand materials. If the sand materials are piled up for a much longer period, some large blocks would appear. If they can not be timely crushed in rotary drum, circumstances like congestion and drying failure would occur. Therefore, it is necessary to install devices in rotary drum for scattering and distributing sand materials evenly and automatically.

Since the particle size of sand materials is relatively small, it is necessary to dry them in air pressure. If the air pressure is a little poorer, hot air could not pass the rotary drum quickly and the total output could be much lower. On the contrary, if the air pressure is much stronger, some unsettled sand material would be brought into finished products and the stability of water content in finished products would be destroyed. As a professional manufacturer of rotary sand dryer, Dingli has been making production for more than 30 years. To deal the problem of wind pressure, we equip the rotary sand dryer with a specialized device, which is of great importance for improving total output and stabilizing the performance of finished products.

Morality oriented, people will be honest; quality rooted, product will be excellent. As a professional manufacturer of drying machines like sand dryer machine, coal slime dryer, industrial dryer and slag dryer, etc, Dingli always regards the quality as life and customer as God.
