Rotary dryer is also known as rotary drum dryer. this machine is idely used in building materials, metallurgy, chemicals, industrial drying slag cement limestone, coal, slag, clay and other materials. The aircraft mainly by the rotary, jam plate, transmission, seals, and other support equipment and components. with a reasonable structure, well-produced, high yield, and low consumption, the advantages of operating convenience. Plant products quality assurance, highest free installation debugging agent can be checked with other plants than quality and prices.

Maximum Utility of Direct Heat Rotary Dryer/the Best Rotary Dryer:

1.Drying workshop process arrangement, in the premise of meet the production, we should strive to compact and reasonable. A dryer workshop span generally preferable 7-9 m, many sets of dryer arrangement in together, center distance of the dryer to 6-7 m.

2. to increase was drying materials and hot gas contact area, improve the drying rate, in before drying, and the material is generally required after crushing. Direct Heat Rotary Dryer/the Best Rotary Dryer of feed particle size often control in 30 -- 60 mm, the biggest less than 80 mm. Different drying material to the dryer production material is certain.

3. Determine the combustion chamber type should be based on fuel varieties, the source, the dryer type, such as the combination plant conditions to choose. Such as: mine has coal slurry drying equipment conditions of the comprehensive consideration of pulverized coal combustion chamber; Inferior coal origin can be used fluidized bed furnace, etc.

4. Dryer the combustion chamber in general to consider setting 'air - flue gas' mixing chamber, the installation of flue gas temperature measurement of the pyrometer and adjust the quantity of mixed cold wind cold air door. Want reasonable design baffle wall, avoid high temperature flame burned directly to the drying machine barrel end and feeding tube. Feeding pipe external heat resistant concrete or brick chute. In addition, reduce feed tube cold air leak into the amount of measures to improve the drying efficiency.

5. Drying thermal system including the combustion chamber, dryer and exhaust dust of three parts. Exhaust fan and precipitator should meet into the dryer combustion air coefficient is not more than 1.2; Dryer in the cold condition wind speed is not more than 3 m/s; Suction hood under the discharge port should install lock wind device; Dust collector and exhaust duct must have heat preservation, adiabatic measures (as long as it can keep the dust removal system is not lower than dew point temperature, not necessarily with thermal insulation material).

6. to prevent wet adhesive materials in a dryer feed bin before occurred in blocking phenomenon, should be reasonable design of feed bin structure, such as using asymmetric geometry hopper; Or increase bucket wall Angle and discharging mouth; Or in the warehouse in addition to prevent the springing of activation of cone or minus pressure plate; At the exit or set tong hole, etc., colleague, still can reduce storage (according to meet the dosage of dryer 2 hours consider), reduce warehouse pressure method is to prevent plugging material. Can also be based on the nature of the material by drying design broken arch discharge vibration hopper dryer for feeding.
