Recently, the silicon carbide drying production line developed by Changzhou Lijun Drying Engineering Co., Ltd. overcomes the weaknesses of static drying with low efficiency and high consumption, and is a new type of highly efficient fluidized drying equipment. In the design process, this machine fully combines the characteristics of flow drying such as air drying and avoids weaknesses, so that the entire machine has a reasonable process structure and superior use performance, and truly achieves the objective of low-cost and high-efficiency fluidized drying. It is reported that this machine has a wide range of applications, and can be used to dry materials such as silicon carbide, black silicon carbide, green carbon silicon, black carbon silicon micro powder, green silicon carbide micro powder, foam ceramic silicon carbide, refractory silicon carbide, etc., with small specific gravity. . The equipment has high thermal efficiency, low energy consumption, small footprint, simple configuration and convenient operation and control. The principle is that the hot air enters the mixing and crushing drying room from the bottom of the dryer through the air inlet at a suitable spouting speed, and the materials are strongly sheared, blown and rotated, so the materials are subject to centrifugation, shearing, collision and friction. It is micronized to enhance mass transfer and heat transfer. At the bottom of the dryer, the larger and more humid granules are mechanically crushed under the action of the agitator. The particles with lower moisture content and smaller particle size are entrained and lifted by the swirling airflow, and further dried during the rising process due to the gas-solid phase. For rotary flow, the inertia of solid phase is greater than that of gas phase, the relative velocity between solid and gas phases is large, and the heat transfer effect between two phases is strengthened, so the drying intensity of the machine is high. Outstanding features: a variety of feeding devices for selection, feeding continuous and stable, will not produce bridging phenomenon. A special cooling device is installed at the bottom of the dryer to avoid deterioration of the material in the high temperature zone at the bottom. Special pressure sealing device and bearing cooling device effectively extend the service life of the transmission. The special air distribution device reduces the resistance of the equipment and at the same time it tends to balance the wind speed inside the tower. The drying chamber is equipped with a grading ring and a cyclone sheet, and the material fineness and the final moisture can be adjusted and controlled. It is understood that the company has advanced experimental equipment for customers to test, and has a first-class design, research personnel and engaged in non-standard design and research and development of drying equipment, at any time to provide technical services to customers. The company has developed a series of products such as drying, granulation, mixing, crushing, dust removal, screening, dry process, wet process, desulfurization, heat exchange, concentration, reaction, storage, distillation, etc., which are widely used in pharmaceutical, chemical, food, Agricultural and sideline products processing and other fields.
Organic pigments are further divided into two subgroups:
Natural Organic Pigments And Synthetic Organic Pigments
Common types include azo pigments, lake pigments, phthalocyanine pigments and quinacridone pigments. They are all artificially synthetic organic compounds. The intermediate, synthesis process and equipment required by such kind of pigments are generally the same as that required by organic dyes, therefore usually manufactured in the dye industry. However, as pigments, they are, after all, different from the organic dyes.
