General structure and manufacturing requirements of high speed mixing granulator

1) austenitic stainless steel shall be used for the direct contact part between high-speed mixing granulator and materials, while non-metallic materials shall be non-toxic, chemical change free, corrosion free and absorption free 2) the granular cylinder of high-speed mixing granulation mechanism is a cone-shaped cylinder at the upper part The bottom of the cylinder shall be made by spinning the whole plate, and the bottom of the cylinder shall be equipped with a cooling jacket to ensure that the cylinder does not heat up during mixing The transition points on all surfaces of the cylinder shall be arc transition, easy to clean and free of dead zone for cleaning At the same time, the granulating cylinder is welded by argon arc welding, and the internal and external parts need polishing treatment, especially the internal surface polishing surface roughness Ra ≤ 0.8 μ m, to ensure that the material will not stick to the wall 3) the feed inlet of the granulating cylinder adopts the quick opening structure, the flange and the can body shall be welded to ensure no dead zone, the cylinder cover is easy to be disassembled and opened, the sealing gasket of the feed inlet and the cylinder cover shall be sanitary grade silicone rubber, and the sealing gasket is convenient to be exchanged, and the structure of the target feed inlet and the cylinder cover shall have corresponding air tightness In addition, the discharge port of the granulating cylinder adopts the electric control discharge valve, the valve plate gasket shall be sanitary grade silicone rubber, the whole discharge channel surface shall be smooth, easy to clean, and there is no dead angle for cleaning 4) the impeller of the high-speed mixing granulator adopts the down rotating mixing, its welding adopts the argon arc welding, and all of them need to be polished The strength of the connection between the mixing impeller and the shaft sleeve should be increased to overcome the instantaneous torque In addition, the distance between the bottom of the pot and the bottom of the mixing paddle should be small (< 1mm), so as to solve the problem of material accumulation at the bottom of the pot At the same time, the cutter adopts side mounted type, which is convenient for blade exchange, and the whole cutter assembly has no cleaning dead zone Among them, the agitator drive shaft and the cylinder seal Zui are easy to use gas seal, and can be gas seal water flushing conversion The seal between the mixing drive shaft and the cylinder and the seal between the granulator shaft and the cylinder shall be reliable to prevent the powder layer from entering and cross contamination 5) austenitic stainless steel polished pipes shall be used for gas and water pipelines, and argon arc welding or quick opening connection shall be adopted When necessary, the air and water pipelines shall be equipped with terminal filters At the same time, the internal cleaning is convenient, and the air and water pipes can be connected to the axial split flow ring When the water and air are converted, the water pressure can be sprayed to each position of the cylinder to ensure that there is no blind area for cleaning, and the water outlet shall be set at the low position of Zui 6) lubricant shall not be used on the surface of exposed parts, and the lubricating points inside the transmission shall not cause any pollution to the exposed structure 7) high speed mixing granulator shall be equipped with mechanical overload protection device In addition, the compressed air pipeline shall be provided with pressure reducing or safety devices.
