INTRODUCTION

As its name implies, sludge dryer is mainly used to dry sludge. Being equipped with single-channel rotary dryer and specially designed feeding device, sludge dryer adopts down-stream drying process. As long as sludge materials enter into the rotary drum, heat transfer happens between material and hot air. Being covered with shells, sludge material has little chance to adhere the drum and cause congestion. At the head of sludge dryer, except for the lifting board, devices for intensifying the evaporation are installed. They not only can conduct heat but also can prevent sludge from blocking the drum and lifting board. The following content will discuss ways to change the drying mesh of sludge dryer.

Users should check the parts of air heating furnace whether being damaged or not like hearth, furnace bar, chimney, inwall and joint, etc. If so, users should repair or change them immediately. Users should confront the sludge dryer, screw up the bolts on the end cups of driving shaft and driven shaft, pull out the two shafts, open the observation door and get the drying chains out. When changing the drying mesh, users should link the drying mesh and support roller together with stainless steel wire at intervals of six or eight mesh support rollers.

When adjusting the tightness of drying chains, users should keep the tightness uniform in different chains. In order to make the sludge dryer run smoothly and normally, users should change the badly-damaged parts immediately. To take the full usage of sludge dryer, users should maintain and check the machine regularly. Small investment can make sludge dryer work for a much longer period, so why not ?
