Rotary dryer is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. It can be used for drying many kinds of materials such as limestone slag, coal powder, slag and clay stone. It is made from rotary body, lifting blade, driving device, supporting device and sealing ring.

Dryer is common machinery which is used to dry a lot of materials. It is mainly uses the external heat to dehydrate the materials with water to reduce its water content.

Dryer drainage pump is the equipment which depends on impeller to generate the vacuum sucking in water from below to the top. If the vacuum is not being formed, water would not be sucked to the top. If liquid level is above the pump, you can use the self irrigation method to pull the water into pump. Under normal circumstances, if the liquid could not be discharged, drainage pump would operate in an empty state.

There are many reasons to cause the noise of drainage pump: fan blade impact of deformation of the drainage pump and damaging of drainage pump. Then you need to take certain specific measures to solve these issues.

We should ensure the solid foundation of drainage pump during the process of installation and debugging process, and the driving machine should be in good operation in the production site. The valve switching should be flexible and the piping layout design be reasonable and feasible. On-site control should be safe, and the operation is complete and accurate to ensure the normal operation of drainage pump.

The new type of rotary dryer made from Zoneding Machine improved these shortcomings; this dryer has the superiority of sample structure, large production capacity, stable database, long service life, widely application, easy operation, low consumption and so on.
