High Efficiency Hot River sand dryer

River sand dryer

1. Product introduction:

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

2. Application range:

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

3. working principle：

The dry 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 the feeding pipe. The inclination of the feeding pipe is greater than the natural inclination of the material, so that the material can be smoothly flowed into the dryer. The dryer cylinder is a rotating cylinder with a horizontal line and a slightly sloping. Material from the higher end of the join, heat carrier by the low-end entry, and materials into countercurrent contact, carrier heating and material together and flow into the cylinder. With the rotation of the cylinder, the material is subjected to the action of gravity to the end of the bottom. 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 the wet material to be dried, then at the feed end of the screw conveyor belt machine or send out.

In the 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 contact surface of the material and air flow increased, in order to increase the drying rate and promote the material forward. Heat carrier is generally divided into hot air, flue gas etc.. Heat carrier by the dryer, generally requires the cyclone in the gas with the material collected. To further reduce the amount of dust in the tail gas, but also by the bag type dust collector or wet dust collector and then discharge.
