AI Technical Summary

Technical Problem

Existing drying equipment is mostly a rotary kiln, which dries quartz sand by contacting hot air. The short contact time results in low drying efficiency and wasted heat.

Method used

The vertically oriented drying drum is equipped with an inner cylinder that vibrates up and down and hollow spiral blades. The spiral blades are equipped with electric heating components. The quartz sand is heated by the electric heating components on the spiral blades, and water vapor is discharged through the vent and the shaft. Combined with the vibration of the inner cylinder, the flow of quartz sand is accelerated to extend the heating time.

Benefits of technology

This improved the drying efficiency of quartz sand, ensured sufficient heating time for the quartz sand, reduced heat waste, and achieved a highly efficient drying process.
