Three drum dryer

Three drum dryer

Rotation speed:4-10 rpm

Capacity:16.63 m³

Applications:yellow sand, core sand, slag, coal slag and small-sized clay.

   Three drum dryer is an improved high efficiency energy-saving products on the base of single drum rotary dryer. This kind dryer improved organic single drum rotary dryer inner structure, increased wet material pre-drying before feeding to the machien and extend wet material inner the machine drying time, coupled with the seal, moisturizing and reasonable supporting measures, making the dryer machine production capacity compared with single drum dryer improved 50-80%.

Three drum dryer

Application:

   Three drum dryer main used to dry the granule materials with a certain humidity and granule size range. Such as yellow sand, molding sand, ore slag, coal slag, small granule size clay and heat resistance high temperature dust polluted other small granule materials. Material after dried, humidity can below 1-0.5%.

Three drum dryer

>> Features

1、Kefan machinery manufactured three drum dryer with features of compact and simple structure, reasonable layout, improve material and heating energy heat exchange rate, then making material with good drying effect.

2、Low basic investment, just 50% percent of the same production capacity single cylinder rotary dryer, reduced once cost.

3、Reasonable working, low energy consumption, high heating efficiency.

4、Easy to realize automatic control, reduce operating worker, saving labor resource.
