Learning from Taiwan modifying activation technology, combined with our own actual experience in powder production, Dongguan Vsunny Machinery Co., Ltd. independently researched and developed deep-processing equipment for surface treatment for a variety of inorganic powder. It will be used to modify the D97≤10μm ultrafine light (heavy) calcium carbonate, or surface treatment of the calcined Kaolin, the production capacity can reach 2.0T~8.0T/h; the activated rate≥96%, and the unit energy consumption≤35kwh/t.
This continuous activation modify & coating machine can be used for dry surface modification of powder of various fineness from 325 mesh to 6000 mesh, such as the surface modification and activation of light calcium carbonate, ground calcium carbonate, washed kaolin, calcined coal kaolin, talcum, quartz powder, mica, aluminum hydroxide, magnesium hydroxide and brucite, ultrafine and precipitated barium sulfate, lithopone, white carbon black, titanium dioxide, coal ash, sericite, zinc oxide and other materials, while at the same time it can depolymerize and scatter the materials
The unit accomplishes the surface treatment of power mainly by means of three “Triangle” modification cylinders. The dry powder and accurately measured reagents were put into the cylinders together, ran in fluidization with the high-speed rotation of rotor, modified rapidly through the collision, friction and shear of the high-speed running powder and the heat produced by the high-speed rotating rotor.
Technology advantages of VSGXJ Series Continuous Activation Modify & Coating Machine
.1.The unit can work continually with a huge processing capacity, suitable for all scales of industrial production. Around 3000 tons can be actively modified each month for 1250 meshes of powder.
2.The modification reagents have a high usage rate, small consumption (around 0.5% to 1% of activation reagents consumption), high powder coating rate and activated rate, and low energy consumption.
3.The equipment has both modification and depolymerization functions. It is proper for all kinds of material sizes, and has a special modification, activation & coating effect on material with small density and big visual rate, such as barium sulfate, silica, mica powder and talcum powder.
4.The machine adopts a special and mixed cold powder and hot reagents high-speed gas-solid phase vortex type operation mode. The mode has high modification efficiency and will not destroy the original shape of the powder.
5.The material is processed under negative pressure with good sealing. No leak of the powder, no pollution; good operational environment; low labor intensity.
6.The cooling and heating processing can be accomplished in the same machine. No independent heating or cooling system is required. The operation is simplified.
7.Independent liquid and non-liquid dosing system. The dosing is continual, stable and even.
8.The continuous activation modify & coating machine is possessed with a mature artificial intelligent control system, with simple and accurate operation. It can be applied to vertical mill computer control system and realizes a perfect connection.
