Flash dryer as a new type of equipment, in recent years in the titanium dioxide industry has been widely used, currently used in titanium dioxide industry commonly used model 1400,1600 type, 1850 type flash dryer, to meet the quality requirements of titanium dioxide. A titanium dioxide company ordered Changzhou casting more than titanium dioxide dedicated flash dryer, recently loaded delivery.
 
Titanium dioxide special flash dryer mainly by the inlet system, heating system, feeding system, dry host, dust collection system, exhaust system, control system and other components. Work, the wet material from the screw feeder into the drying room, the material in the drying room and high-speed rotation of the hot air meet the fine powder material is hot air with the upper part of the drying room to move, can not take away the material falls in the bottom of the drying room, Crushed by the bottom of the crushing device, the material was quickly dispersed, the contact area of materials and hot air increased rapidly. In the role of centrifugal force (top of the grading device), to achieve the degree of drying and a certain degree of fineness of the product was blown out of the grading device, the material in the process of rapid drying.
 
Titanium dioxide dedicated flash dryer with high technological content, high standardization, environmental protection, safety, low consumption, simple maintenance, etc., in the design structure:
 
① the bottom of the dryer set inverted cone structure, so that the drying gas flow through the bottom of the gradual expansion of the bottom of the air flow is relatively large, the upper air flow is relatively small, so that the lower part of the large particles in fluidized state, the upper small The particles are also in fluidized state, and the hot air along the vertebral body rotation, improve the bottom of the wind speed, reducing the length of the cantilever part of the mixing shaft, increasing the safety and reliability of operation; can bearing on the machine, effectively prevent the bearing at high temperature Area work, thus extending the bearing life.
 
② stir the teeth set on the scraper, the material was stuck in the mixing teeth at the same time, was thrown to the wall, bonding on the wall, if not timely scraping, serious equipment will cause vibration, and even lead to stir The Stirring set on the scraper, you can peel off the material on the wall in time to avoid sticky wall.
 
③ The number of revolutions of the stirring shaft is controlled by the stepless speed regulation motor. According to the product size requirements to choose a different speed, the faster the stirring shaft speed, the smaller the size of the product.
 
④ The upper part of the dryer is equipped with a classifier to change the air flow rate by changing the hole diameter of the classifier and the height of the classification section, and control the particle size and quantity of the dryer, the final water content and the residence time of the material in the drying section.
 
⑤ The number of revolutions of the screw conveyor of the feeder is controlled by the inorganic speed control motor. The feed rate is controlled according to the material properties and the drying process parameters.
 
⑥ equipment compact structure, small footprint, set dry, crushed, graded as one, is swirling technology, fluidization technology, jet technology and convection technology of organic combination, do not need to dry after crushing, screening, simplifying the Production process, saving power and equipment costs.
