High speed centrifugal spray drying machine

A high-speed centrifugal spray drying machine is a device used in industrial processes to convert liquid or slurry materials into dry powders or granules. It is commonly used in various industries such as food, pharmaceuticals, chemicals, and ceramics.

The machine operates on the principle of atomization, where the liquid or slurry material is atomized into fine droplets using high-speed rotating discs or nozzles. These droplets are then rapidly dried through contact with a heated gas stream, typically hot air or nitrogen. The gas stream evaporates the moisture from the droplets, leaving behind the solid particles.

Traditional atomizers generally use the principle of mechanical (gear) speed increase to increase the rotation speed. However, due to the plasticity and yield force of steel, the rotation speed is always limited to 8000-12000 rpm, so the rotation speed is 2-30000 rpm. , High-power motors with power above 11kw (especially above 100KW) are blank in China and almost zero abroad. In order to meet the needs of the lithium battery industry, high-power, high-speed centrifugal spray dryers have become an urgent need.

After years of technology accumulation, we have cooperated with several domestic universities and enterprises to jointly develop "air suspension + high-speed transmission device" in different subjects ranging from materials to machinery and fluid mechanics. Under the premise of this device principle, the permanent magnet and high-pressure air are organically combined to generate strong radial and axial thrust, so that the spindle is completely suspended in the set space, and then the electromagnetic field drives the spindle to rotate, completely changing the traditional The mechanically designed transmission structure enables the spindle to work stably at ultra-high speeds. Designing a large-flow, high-speed centrifugal spray drying unit first requires a high-speed, high-power motor. At present, the motor speed we design is between 2000-35000 rpm.
