The centrifugal atomizer is known for its high precision, high speed and energy saving. Not only can it achieve uniform and controllable particle size atomization, but the maximum single-machine processing capacity has reached 200t/h. This provides a powerful means of atomization for the development of LPG high-speed centrifugal spray dryers. The centrifugal atomizer uses a belt drive and improves the lubrication system, and also achieves good results. These achievements are one of the important reasons for the rapid growth of the application of centrifugal atomization.
