Henan Fote Machinery does some analysis for you:

By the hot air flow rate by the heat and mass transfer theory shows that to improve the flow rate of dry air, directly improving the heat transfer coefficient and mass transfer coefficients, drying rate increases, but also the timely replacement of the hot air, conducive to the proliferation of outside process. However, the improvement of the hot air flow rate for a certain length of the rotary dryer, will reduce the residence time of hot air in the drying of the barrel body that may affect the thermal efficiency, resulting in a waste of heat. By increasing the material and the hot air in the cylinder axial unit length of contact time and contact area, through the transformation of the lifting plate materials in the cylinder cross-sectional dispersion of purpose, by increasing the dryer cylinder length.

In general, the higher the temperature of the hot air temperature of hot air, heat transfer rate and mass transfer rates higher, in the case of the same amount of water evaporation, the amount of hot air can be reduced, the exhaust heat loss is reduced. However, control of most of the imports of cement plant dryer hot air temperature is low, even if the downstream dryer temperature of 700 ℃ or so, so the extent permitted by the cylinder, the substantial increase in imports of hot air the temperature is not feasible.

Third. Into the feed size and feed uniformity in the drying rate in certain circumstances, the material and the hot air the greater the contact area, total dry the better. The smaller the particle size, the internal diffusion resistance of the smaller, help to improve the drying rate. Pellet group contrast, is easy to form a gas layer, to prevent the inner material of the heat and mass transfer. Therefore, in the drying of materials, the material and the broken handle. The amount of feed material current premise. Can guarantee the stability of the dryer thermal load and thermal regime on the one hand, material moisture content after drying, so that the load of heating of the hot stove, etc.; the other hand, can also be easy to grasp and control the exhaust.

At the present, Fote Heavy Machinery has set up three state level machinery research institutes, and we also produce various kinds of coal slime dryer, sludge drying machine and free service for assembling various kinds of production line.

Ball Mill is a crucial equipment for grinding after materials are crushed, it is an efficient tool for grinding various materials into powder, it is Widely used for the cement, the silicate product, new type building material, fire-resistant material, chemical fertilizer, black and non-ferrous metal, glass, ceramics.

Working Principle:

This Ball Mill, a horizontal type and tubular running, has two warehouses. It runs along the outside gear. Materials spirally and evenly enter the first warehouse along the input hollow axis by input devices. In the warehouse, there is a ladder scale board or ripple scale board. Steel balls of different specifications are installed in the scale board of the ball mill. When the barrel body rotates, centrifugal force is produced. At the same time, the steel balls are carried to some height and then fall to grind and strike the material. After being grinded coarsely in the first warehouse, the material then enters into the second warehouse of the ball mill for regrinding. In the end, the powder produced by the Ball mill is discharged by output material board.

After the material entering the hollow axis by the feeder, the material will be taken evenly and spirally into the first warehouse, where there is the ladder liner or the ripple liner with the different steel balls. When the tube structure revolving produces the centrifugal force, the steel balls will be carried higher to some extent, and then fall down to strike and grind the material. After grinned generally in the first warehouse of ball mill, the material then will be taken into the second warehouse, in which there is the flat liner, the material will be regrind and then be discharged through the discharge grate liner.

The main role of dryer is serve as drying machine,which use steam heat. The drying function of dryer are great with strong adjustability. Copy board holds the amount of materials fill rate of the important parameters in determining the desiccator. In the calculation of the copy board holds the material free surface and the horizontal angle between the generally assumed to be the angle of repose of the material. Different angle of repose, and copy geometric dimensions of the board, you can determine the holdings of the unit length of a single copy board.

Rotary drum dryer copy board layout:

(1)They are distributed copy board and lifting-type copy board, it can ensure the material is more evenly distributed in the drum cross section. The powdered material or with a certain block of material, copy board is more appropriate. The industry set the copy board for pulverized coal, DCP, light acid, calcium and powdered graphite and other materials commonly used in the indirectly heated rotary drum dryer.

(2) The fan form of copy board fan copy board by lifting type copy board consisting of mutually unintelligible fan parts. Gradual decline in the material along the tortuous channel, full contact and dry with hot air. This copy board applies to the massive, fragile and high density materials.

(3) Lifting-type copy board this copy board in a wide range of industrial application, mainly applicable to a large piece of material and ease of bonding materials. This copy board structure, the dryer is easy to clean, drum filling rate is lower.

(4) Cellular copy board materials are dispersed in a small grid, thereby reducing the height of material fall, reducing the amount of dust generated in the drying process, therefore, it applies to the crushing of materials prone to dust. The higher fill rate, up to 0.15-0.25.
