For mining machinery industry, sand rotary dryer is the commonly used machine for drying materials like river sand, artificial sand and quartz sand, etc. By virtue of the outstanding drying efficiency, the Dingli sand dryer machine is well received among the global markets. Since the rotary sand dryer has remarkable drying effect, except for the perfect coordination between auxiliary parts, the well control of temperature is also a key factor. As we all know, high temperature is the best way to acquire good drying effect.

The drying process of sand dryer machine is generally divided into three stages: primary heating, warming and heat keeping. According to the rich production experience, we summarize some data and users can take them as reference. For primary heating, the temperature is better controlled at 500-800℃ for about 15 minutes. As to the warming stage, the temperature is better to be kept at 1,000-1,500℃ for more than one hour. With regard to the last stage, it is the continuous keep that makes the final result get standard.

During the above three stages, users should pay much attention to the color changes of material, since the color is an index to judge the water content in material whether being standard or not. Of course, since sand dryer machine has different specifications and raw material has different properties, the temperature for drying should be adjusted well according to actual demands. If you are in the field of mining or want to start business with sand, the sand rotary dryer is definitely your first choice. We are committed to offering best products and services for you.
