M k manufacturing company manufactures a rotary disk atomizer. This is used in all types of spray dryer plants. Feed is introduced centrally onto a wheel or disc rotating at speed. The feed flows outwards over the surface, accelerating to the periphery. Feed, on leaving the periphery, readily disintegrates into a spray of droplets. Rotary atomizers form a low-pressure system. A wide variety of spray characteristics can be obtained for a given products through combinations of feed rate, atomizer speed and atomizer design. Designs of atomizer wheels have vanes, spacers or bushings. Vanes are high, wide, straight, or curved: spacers cylinders or formed: bushings are used in more specialized fields, eg, for handling abrasive with bushings are used in more specialized fields, eg, for handling abrasive feeds. Wheels can be operated to produce sprays in the fine to medium-coarse size range. Peripheral velocities can reach 300 m/s in industry in specialized cases. Discs are used to meet coarse-spray requirements.
