Riversand dryer

1. 1.     Productintroduction:

Riversand dryer is widely used in building materials, metallurgy, mineralprocessing, chemical, cement and other industries, mainly used for ore,limestone, clay, sand, quartz sand, water, slag and other wet and heavymaterials. Slag drying production line, mainly by the rotating cylinder body, awind guiding device, high-speed scattered equipment, lifting plate, automaticcleaning device, a transmission device, conveying equipment, air equipment,reducer, a supporting device and a sealing device etc. parts. The full set ofdrying equipment, reasonable, the production of good, stable performance,advanced technology, high output, low energy consumption, small area, highdegree of mechanization.

1. 2.     Applicationrange:

Riversand dryer is a kind of material handling a large dryer. As a result of theoperation is reliable, the operation is flexible, the adaptability is strong,the processing capacity is large, and is widely used in metallurgy, buildingmaterials, video, light industry, coal, medicine and mineral industry. Rotarydrum dryer is generally used in granular materials, and can also be used forsome of the method of the infiltration of the material to dry sticky pastematerial or higher moisture content of the material. It has the advantages oflarge production capacity, wide application range, small flow resistance,operating on a wide range of allowable fluctuations, easy operation, etc.. Slagdryer, drum dryer used in sand, slag, slime, chicken manure and cow dung etc.

1. 3.     workingprinciple：

Thedry wet material is sent to a hopper by a belt conveyor or a bucket elevator,and the feeding machine of the hopper is fed into the feed end through thefeeding pipe. The inclination of the feeding pipe is greater than the naturalinclination of the material, so that the material can be smoothly flowed intothe dryer. The dryer cylinder is a rotating cylinder with a horizontal line anda slightly sloping. Material from the higher end of the join, heat carrier bythe low-end entry, and materials into countercurrent contact, carrier heatingand material together and flow into the cylinder. With the rotation of thecylinder, the material is subjected to the action of gravity to the end of thebottom. Wet material in the cylinder body to move forward in the process,directly or indirectly get the load of the heating element to heat, so that thewet material to be dried, then at the feed end of the screw conveyor beltmachine or send out.

Inthe river sand dryer cylinder wall of the barrel is provided with a copy board,which is the role of the material copied and spread, so that the contactsurface of the material and air flow increased, in order to increase the dryingrate and promote the material forward. Heat carrier is generally divided intohot air, flue gas etc.. Heat carrier by the dryer, generally requires thecyclone in the gas with the material collected. To further reduce the amount ofdust in the tail gas, but also by the bag type dust collector or wet dustcollector and then discharge.
