Roatry bell generally has three installation methods: fixed, reciprocation machine, robot, paintfrom the center to the high speed rotating bell head, bell head is charged and 80KV high voltage transmission to the paint, when the paint touches the bell head. is charged with high voltage negativ charge, because thsescharges reple each other, when the paint leaves the bell head, paint particles it's split by the charge into smaller and nore uniform particles until the surface thnsion of the coating is balanced with the charge repulsion 

The combination of electrostatic effect and hgh sped rotating centrifugal force producesbetter and more uniform coating particles, the high voltage charged particles are attracted  to wellground ded workpicees, resulting in excellent surface quality and high coating transfer efficiency
