Rotary Drum Dryer For Sand/ Fertilizer/ Slag/ Sawdust

1. Introduction
Rotary Drum Dryer adopts the means of Drum marginal transmission, flange connection, direct heat transfer. It is used for drying fertilizer, ore, mineral, metal, coal, sand, carbon, wood chips, slag, animal manure, etc.


2. Aplication
(1) Ore:ore,slag,mineral power,limestone, quartz, fluorite powder,iron ore,metal ore concentrates, metal tailings,etc.
(2) Metal: metal powder, iron powder, iron filings, steel scrap, copper filings, etc.
(3) Chemical industry: gypsum powder of desulphurization gypsum stir-frying half water model and building gypsum powder,clay,diatomaceous earth, kaolin,bauxite
(4) Coal: raw coal,coal slime, coal,coal ash,coal cinder
(5) Sand: sand,quartz sand,moulding sand,river sand
(6) Various crystals: light calcium carbonate, activated clay, magnetic powder, graphite, mineral mud, clay, lime slurry, ore slurry, phosphorus slag, aluminum red mud, feldspar powder, fly ash, blue carbon, potassium, sodium, calcium, barium and alkali metal or silicate minerals in the alkali metal.
(7) Wood: sawdust, small wood chips, wood veneer.
(8) Fertilizer: compound fertilizer, organic fertilizers, inorganic fertilizers, ammonium sulfate fertilizer
(9) Agriculture: straw, grass, turf.
(10) Animal manure: chicken manure, duck manure, cow dung, etc.


3. Working Principle
Materials are sent to hopper of Rotary Dryer by belt conveyor or bucket elevator, then enter the barrel installed with slope to horizontal line from the higher side, and hot air enters the barrel from the lower side, and then materials and hot air mix together. Materials go to thelower side by gravity when the barrel is rotating. Lifters on the inner side of barrel lift materials up and down in order to make materials and hot air mix completely, which is designed to improve the producing efficiency of Rotary Dryer.
