As an amazing machine for drying wet materials like sand and coal powder, sand dryer machine is more and more used today. While after long-term utilization, problems would more or less occur and inconsistent drying is one of them. The following content mainly discusses about the reasons for causing uneven drying. Firstly, the water content in sand material is unstable during the drying process of rotary sand dryer. For example, if sand materials with water content about 35% are mixed together with sand materials with water content about 30%, the revolving speed of rotary drum has to be adjusted continuously. Therefore, the water content in dried sand is inconsistent.

Secondly, the quality of coal would subjectively influence the performance and water content of dried sand. Since the quality of coal fuel is inconsistent, we should clean the coal coke on walls of air heating furnace before operating the sand dryer machine. During the cleaning period, the air blower should stop working. Thirdly, the operant level of operators would influence the performance of dried sand. If operators can not well adjust the revolution of motor, the water content in dried sand would be either high or low.

With three state-level machinery research institutions and more than 50 national patents, Fote Heavy Machinery has established favorable relationship with department of science and technology as well as key universities and colleges. All these enables the leading position of Fote in mining machinery manufacturing industry. therefore, Fote products are worthy of trust.
