Technical specification of Q3210 shot blasting machine

1.Components and function

Q3210 shot blasting machine consists of blasting system, blasting chamber, abrasive circulation system (separator, bucket elevator, screw conveyor), dust collection system and electric control system. The surface finish level is Sa2.5.

2.Shot blasting system

Shot blasting system consists of blasting chamber and shot blasting machine assembly. The abrasive media like the steel shots, grits are applied on the metal surface driven by the centrifugal force from the blades. Workpieces will be de-rusted, cleaned and roughened in blasting system to reach customer’s finishing level.

3.Blasting chamber

Blasting chamber is welding structure, inside has rubber belt and drive mechanism, at the bottom of the chamber has a screw conveyor, indoor adopts wear-resisting guard protection, blast wheel fixed on the top of the chamber. In the blasting chamber, the end disk is protected by ZGMn13 material, which has high wear resistant performance. Prolong service life, reduce the cost and reduce maintenance frequency.

4.Shot blasting machine assembly

This machine has 1 set of high speed & performance blast wheels. One blast wheel has eight blades. It takes 5 to 10 minutes to replace 8 pieces of blades. Material of blades, control cage and distributor is Cr20S high-chromium cast iron (USA: 5115G51150 Model), which has long service life. Generally speaking, lifetime of blade is over 500 hours, and lifetime of impeller and control cage is over 800 hours. All wear parts are the market most universal national standard parts.

5.Abrasive circulation system

The system includes following parts: hopper, abrasive flow pipe, abrasive control valves, screw conveyors, bucket elevator, separator.

6.Screw conveyor

Screw conveyor consists of cycloid needle wheel decelerator, screw axis, conveyor shell, bearing, etc. It is a standard transverse conveying device, an important part of abrasive circulating system. The screwing blade is made of 16Mn.

This unit is responsible for convying the abrasive to the elevator. Screw conveyor located at the bottom of shot blasting chamber, the spiral blade welding in the drive shaft. Conveyor motor drives screw conveyor to send abrasive to discharge outlet, then the mixed abrasive will be conveyed to elevator bottom.

On both ends of the screw conveyor adopt triple seal protection. the abrasive and dust will drop to the clearance between end plate and bearing once leak out, will not enter the bearing. Screw conveyor shaft with sensors detecting unit can detect the working state.
