What is the difference between shot blasting and sand blasti


The main difference is that in the shot blasting process we use throwing wheel and in sand blasting process compressed air is used.
Shot blasting: abrasive gets acceleration through the throwing wheel, which is rapidly turning in a special steel housing, with one side oriented opening. Shot blasting is used for blasting metal, different profiles and welded constructions. Qingdao Puhua is internationally recognized manufacturer of shot blasting machines. For over 20 years we share our knowledge and experience with our business partners all over the world.

Sand blasting: abrasive is dosed into the stream of compressed air and gets a real acceleration in the outflow from the blasting nozzle. Sand blasting is used in the chambers and cabins for hand blasting.
