Rotary drum dryer is a common drying equipment in mining and processing enterprises, which is mainly used for drying mud, coal, fertilizer, cement, chicken manure, corn, and other materials. But after a long time of use, equipment often has a different degree of wearing and tearing, so we have to take appropriate measures to enhance the life cycle of the dryer.

Concrete measures are as follows.

First of all, dryer refractories are key factors in prolonging the life of dryer. Refractories used affects the dryer operation rate, if frequent stop-repair the kiln refractory lining, which increases the strength of the overhaul, also affects the normal operation of the dryer, and increases the processing cost of labour in disguise, causing huge economic losses.

Service life of the refractory material depends on the operation of the dryer, the corresponding process and selection of refractories, correct laying methods.Laying refractories will correctly and effectively is the key to service life of the machine, not only helps to extend the service life, can also eliminate some of this should lead to the premature failure of stress.Wrong building methods will greatly shorten the service life of the refractory material.



Second, addition in drying machine in of anchorage pieces more used steel material, rivets of welding has strictly of requirements, should strictly check, in construction site check in the, often will found anchorage pieces welding not prison of problem, sometimes even will appeared with feet a touch on shedding of phenomenon, if not timely processing, in production Shi has may will appeared pouring material big area collapse of consequences (in wet method kiln Shang once appeared had due to anchor nail welding not prison, caused kiln tail long about 13 m around pouring material of big area collapse) has may will caused personal accident.
