Sand Dryer Sand Dryer Product Description
A sand dryer, also used as a yellow sand dryer, is a dryer that handles large amounts of materials. Due to its reliable operation, flexible operation, strong adaptability and large processing capacity, it is widely used in the building materials, metallurgy, food, chemical, coal, pharmaceutical and mining industries. Sand dryer, or yellow sand dryer
is a drum dryer. Generally suitable for granular materials, it can also be used to dry sticky paste materials or materials with high moisture content by partially mixing materials. Especially for drying sand, the sand dryer has excellent drying effect. The advantages of sand dryer or yellow sand dryer are large production capacity, wide application range, small flow resistance, large allowable fluctuation range in operation, easy operation, etc.
Working Principle
The sand is sent to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe of the feeding machine
of the hopper. The inclination of the feeding pipe should be greater than the natural inclination of the material
so that the material can flow into the sand dryer (yellow sand dryer) smoothly. The dryer cylinder is a rotating cylinder, which is slightly inclined with the horizontal line. Materials are fed in through the higher end, and heat carrier enters through the lower end, and contacts with materials in counter-flow direction. Sometimes heat carrier and materials enter into the cylinder in parallel flow.
As the cylinder rotates, the materials move to the lower end under the action of gravity. When the wet materials move forward in the barrel, they receive the heat carrier directly or indirectly, and the wet materials dry. Then, the wet materials are sent out through the discharge end via a belt conveyor or screw conveyor. The inner wall of the barrel of the sand dryer (yellow sand dryer
dryer) is equipped with a lifting plate. Its function is to lift up the material and scatter it down to increase the contact surface between the material and the air flow. , to increase the drying rate and promote material advancement. Heat carrier
Generally divided into hot air, flue gas, etc. After the heat carrier passes through the dryer, a cyclone dust collector is generally required to collect the materials in the gas. If you need to further reduce the dust content of the exhaust gas, it should be discharged after passing through a bag dust collector or wet dust collector.
Sand is composed of silica, usually in the form of quartz, which is chemically stable and hard enough to resist weathering.
Sand is made up of minerals and tiny rock fragments. Rock fragments are formed by erosion and weathering of rocks. The composition of sand varies from place to place.
Feldspathic sandstone is a type of sand or sandstone with a high content of feldspar (aluminum silicate), usually formed by the weathering and erosion of nearby
granite.
Sand is a purely natural material or machine-made sand, which contains a lot of moisture and impurities. The advent of sand dryer
undoubtedly solves the problem of sand dehumidification and reduces our burden on tedious work
br/> burden. The dryer adopts advanced technology and is an efficient drying equipment developed based on the actual situation of the domestic sand and gravel industry. It has a reasonable structure and greatly reduces the failure rate.
