Round bar shot blasting machine belongs to roller through-type shot blasting machine,is specialized in processing bars,round steels etc. which is belonging to custom-made shot blasting machine.With the development of society,in the industry of steel,shipbuilding,steel structure etc. manufacturing departments are facing the problems of workpiece clear.
In order to produce workpiece with high quality,the following manufacturing procedure must guarantee that the material has no dust,scales and dirt,no pollution.Having proved by various application,shot blasting is an ideal processing method.
The round bar shot blasting machine can go into effect for the initial raw material shot blasting to remove its dust and welding slag and oxide layer.By shot blasting,the surface roughness of materials are being improved to some extent,so as to remove stress,improve steel structure and steel surface painting and anti-corrosion performance.
