Applications: three drum dryer is widely used in straw briquette fuel, charcoal machinery, wood pellet, sawdust briquette, agricultural engineering and other industries. Such as dried corn stalks, soybean straw drying, drying cotton stalks, wheat straw drying. Main features: 1, equipment investment required is 1/6 of imported products. 2, the material to ensure that 0.5% final moisture is dry mortar and slag powder production line product of choice. 3, cylinder self-insulation thermal efficiency up to 70% (traditional monocular dryer thermal efficiency of only 35%), to improve the thermal efficiency of 35%. 4, the fuel can be adapted to coal, oil and gas. Can bake 20mm below the block material, pellets and powder materials. 5, than monocular dryer to reduce the area of ??about 50%, lower construction investment is about 50%, 60% reduction in power consumption. 6, according to user requirements easily control the desired final moisture indicators. 7, the outlet temperature is low, long time dedusting equipment. 8, no size gear, the use of wheel drive. Materials: river pebbles, granite, basalt, iron ore, limestone, quartz, diabase and other characteristics: lower production costs, broader applicability, broader applicability, advanced automation, production operations more convenient
