Silicon Carbide Dryer (Linmu Sanda New Material Co., Ltd.)

Application client:
Selected products::Linmu Sanda New Materials Co., Ltd.
Materiel:: Silicon carbide
Brief introduction:Silicon Carbide (SiC) is made of quartz sand, petroleum coke (or coal coke), wood chips (need to add salt when producing green silicon carbide) and other materials through high-temperature resistance furnace smelting. Silicon carbide also has a rare mineral in nature, Moissanite. Silicon carbide is also called moissanite. Among contemporary non-oxide high-tech refractory raw materials such as C, N, B, silicon carbide is the most widely used and economical type, which can be called gold steel sand or refractory sand. At present, silicon carbide produced in China is divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals with a specific gravity of 3.20 to 3.25 and a microhardness of 2840 to 3320kg / mm2.

Detailed description

Material overview:

        Silicon carbide (SiC) is made by high-temperature smelting of resistance sand using quartz sand, petroleum coke (or coal coke), wood chips (need to add salt when producing green silicon carbide) and other raw materials. Silicon carbide also has a rare mineral in nature, Moissanite. Silicon carbide is also called moissanite. Among contemporary non-oxide high-tech refractory raw materials such as C, N, B, silicon carbide is the most widely used and economical type, which can be called gold steel sand or refractory sand. At present, silicon carbide produced in China is divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals with a specific gravity of 3.20 to 3.25 and a microhardness of 2840 to 3320kg / mm2.

Overview:
    XSG series rotary flash dryer is a new type of drying equipment developed by our factory on the basis of introducing and absorbing advanced foreign technology. The machine has advanced technology, reasonable design, compact structure, wide application range, large production capacity, good product quality, high efficiency, and energy saving. Drying, crushing, and screening are completed at one time in one device, eliminating environmental pollution, and the performance of the whole machine reaches International advanced technology level.

Principle: The
    hot air enters the stirring and crushing drying chamber from the bottom of the dryer at the appropriate spraying speed through the inlet pipe, which produces strong shearing, blowing and rotating effects on the material, so the material is divided by centrifugation, shearing, collision and friction Micronization enhances heat and mass transfer. At the bottom of the dryer, the larger and more humid pellets are mechanically broken under the action of the agitator, and the particles with lower moisture content and smaller granularity are entrained and raised by the rotary airflow and further dried during the ascent. The gas-solid two-phase rotation flow, the solid-phase inertia is greater than the gas phase, the relative velocity between the solid-gas two phases is greater, strengthen the mass and heat transfer between the two phases, so the machine has high production intensity.
Features:
● A variety of feeding devices are available for selection. The feeding is continuous and stable without bridging during the process.
● A special cooling device is installed at the bottom of the dryer to avoid the deterioration of the material in the high temperature area at the bottom.
● Special air pressure sealing device and bearing cooling device can effectively extend the service life of the transmission part.
● The special air distribution device reduces the resistance of the equipment and effectively provides the air volume of the dryer.
● The drying room is equipped with a grading ring and a swirling sheet, the material fineness and final moisture can be adjusted. (For example, the final moisture of calcium carbonate can be adjusted to ≤0.1%)
● Compared with other drying methods, it can effectively increase the proportion of materials.
● The circumferential air velocity in the drying chamber is high, and the residence time of the material is short, which effectively prevents the material from sticking to the wall and the deterioration of the heat-sensitive material.

Applicable materials:
● Inorganic: boric acid, calcium carbonate, hydroxide, copper sulfate, iron oxide, barium carbonate, antimony trioxide, various metal hydroxides, various heavy metal salts, synthetic cryolite, etc.
● Organic matter: Atrazine (pesticide insecticide), lauric acid, benzoic acid, benzoic acid, bactericidal dan, sodium oxalate, cellulose acetate, etc.
● Ceramics: kaolin, silica, clay.
● Dyes: anthraquinone, black iron oxide, indigo pigment, butyric acid, titanium hydroxide, zinc sulfide, various azo dye intermediates.
● Foods: soy protein, gelatinized starch, distiller's grains, wheat sugar, wheat starch.
