Dryer Machine

Introduction:

Sand dryer machine can be also called drum dryer, or dryer drum or rotary dryer machine, etc, it is a kind of drying equipment widely used in mining system. This kind of dryer mainly applicable for drying wet material within certain range humidity. For example, yellow sand be used to the mortar powder industry, sandstone of all specifications used in casting industry etc.

Working Principle:

The rotary drum dryer has three layers of drum, the material is fed into the inner drum, when the drum rotate, the lifting plates on the inner drum will guide the material rolling along the peripheral direction and go forward along axis direction of drum, at the end of drum, the material go into the middle drum, will do similar motion when it is in inner drum, the material will move to the inlet of drum, then enter into the outer drum, will do same motion when it is in inner drum, at last the material will come out from the outside drum, the temperature will 60-65 degree Celsius.

Advantages:

1.The equipment is made of wear proof manganese plate. Its service life is 3 to 4 times as long as ordinary steel plate.
2.The original water content of materials is 15%, after drying ,the water content will left 0.5%~1%.It is first choice for slag powders of cement plant, dry mortar of production line.
3. Compared with the tradition single cylinder dryer, the thermal efficiency is increased more than 40%.
4.The fuel can be anthracite, bituminous coal, coal, oil or steam. The lump materials, aggregates or powder materials can be dried by this dryer.
5.Compared with the single cylinder dryer, its space occupied and civil engineering can be reduced 60%, and its installation is more convenient.
6.No leakage phenomenon, completely solved the difficulty of sealing.
7.The temperature of output sand is less than 60℃, which can convey into silo directly, without enter into cooling tend.
8.The outer cylinder temperature is 60℃ or less, exhaust temperature lower than 120℃ , can effectively prolong the service life of draft fan.
9. Coal consumption is 1/3 of the single cylinder dryer&rsquos, power saving is 40%, normally, the coal consumption is less than 9 kg to dry one ton material.
