Lignite coal dryer has strong anti-overload capacity, big handling capacity, low fuel consumption and low drying cost. Rotary lignite coal dryer adopts low-temperature four-level drying technology and is able to evaporate the water of lignite to below 13% on the condition of maintaining the lignite to be dried unchanged. The dryer machine is made up of a large, rotating aylindrical tube, usually supported by concrete columns or steel beames. The dryers slopes slightly so that the discharge end is lower than the materials feed end in order to convey the materials through the dryer under gravity. According to its heating methods, the rotary dryer divided into direct heated and indirect heated dryer. A direct heated dryer uses the combustion gases generated by the heater mixed with an artificially heated gas. These systems are only used when the heater exhaust cannot contaminate the work materials. And for another indirect heated rotary dryer, the heater warms a second gas which enters the drum while any combustion gases remain separate. As we all know, the main parts of the lignite coal dryer once are worn, we should replace and repair them immediately, now Henan Fote Heavy Machinery Co.,Ltd will tell you when to repair and replace the worn parts. 1. Transmission gear tooth is worn by 30%, or in the 0.5 module, the damage of flange of wheel is unrecoverable, at this time, we need to replace and repair the transmission gear. 2. There are surface abrasion into taper, polygon of the tyre or cracks appeared in the cylinder, we need to repair them. 3. There are cracks or local deformation in the cylinder, we need to repair or replace. Any more information about the maintenance and repairment of the different industrial dryer (such as sawdust drying machine, sawdust rotary dryer, slag dry and so on), please contact Fote Machinery through email: info@sinoftm. Henan Fote Heavy Machinery Co., Ltd. will send you the response as soon as possible.steel slag dryer:
The Term Paper on Heat Pump
Outdoor components of a residential air-source heat pump A heat pump is a machine or device that transfers thermal energy from one location, called the “source,” which is at a lower temperature, to another location called the “sink” or “heat sink”, which is at a higher temperature. Thus, heat pumps moves thermal energy opposite to the direction that it normally ...
