Sand rotary dryer, with remarkable features of high drying efficiency and reliable operation, has been well-received among the global markets. If you are in the mining field or want to start business with sand, rotary sand dryer must be a good helper for you. Congestion in sand rotary dryer is a troublesome question either for users or manufacturers. Reasons for causing blocking is what we need to discuss about in the following content.

The main plugs for causing congestion in sand dryer machine are some mechanical foreign matters, large sand blocks and crystal substances, etc. If the rotary sand dryer is completely blocked, we can judge it from two circumstances. One is the sudden rise of pressure in high-pressure pump and the other is the clear rise of temperature in feed inlet. If the sand rotary dryer is partly blocked, the pressure changes in high-pressure pump would not be clear. To judge it, we should start from the temperature changes of exist gas. Either for the part blocking or complete blocking, we should deal immediately. Or else, a lot of sand materials would be useless and some other failures would be triggered.
