Horizontal rotary dryer is the most common and widely used in mining equipment of a drying equipment. Suitable for dry magnetic, heavy metal and non-metallic mineral, concentrate and clay cement industry and coal industry of coal slurry, etc. It is characterized by high productivity, easy to operate. Drum dryer cylinder is a horizontal rotating cylinder, its internal used to different kinds of copy after welding have staggered Angle plate, rotary kiln body according to the requirements set with different types of refractory brick, the material feed end in order to prevent the fall has door ring and spiral copy board. With reasonable structure, well made, high output, low energy consumption, convenient operation.
The classification of the horizontal rotary dryer:
According to the drying medium and wet materials can be divided into direct heat transfer between heat transfer drum dryers (direct contact heat transfer of drying medium and wet material) and indirect heat transfer drum dryers (dry calories by compared.in indirectly passed to the wet material) two kinds. Indirect heat transfer drum dryers transfer efficiency low and complicated structure, rarely choose, in this not introduced. Direct heat transfer drum dryers, according to the direction of the drying medium and material flow, and is divided into two kinds of downstream and upstream.
Performance characteristics:
Combined feed device by my company design and manufacture of the dryer in feed device made a variety of technical innovation system, by using the new type combined feed device, overcome the "wind tunnel" phenomenon of traditional dryers, high thermal efficiency, coal consumption reduced by 20% or so.
2. Apply to a variety of combustion furnace use: high temperature fluidized bed, the grinding powder coal stove and artificial coal stove.
3. The size of the gear transmission pin column can change gear, to replace the traditional steel casting gear, save the cost of investment, and greatly reduces the maintenance cost and time.
4. The central control system, which can realize large enterprises microcomputer central monitoring management.
Working principle:
The dryer of heat from the combustion device, the dryer adopts downstream type heating mode. Therefore need drying of material, from the feed tank, feeding sneak into the cylinder, and copy is spiral plate to after. Materials because of the dryer tilted, on the one hand, the gravity and rotary low back end, on the other hand the material being repeatedly grabbed, copy board to top constantly raise and down again, make the material within the cylinder form uniform curtain, sufficient heat exchange with tube in the heat flow, due to the material repeatedly Yang, contains moisture by drying, gradually so as to achieve the purpose of drying.
