Product Description

Tumble Belt Shot Blasting Machine for Small Castings and Forgings

1. Application
Q32 shot blasting machine is a specially designed machine used in the surface cleaning for various small parts. It can realize the shot blasting automatically.

2 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.

2.1 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.

2.2 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.

2.3 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.

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

2.4.1 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.

2.4.2 Bucket elevator
Housing of bucket elevator is welded of steel plate.
There is a checking door for maintenance and replacing buckets at the bottom of the housing.
The buckets are screwed to rubber belt which is stretched between two pulleys.
Belt material: Polyester.
Consists of cycloid needle wheel decelerator, upper and bottom barrel, belt, bucket and tensioning device, etc

In operation, the hoppers fixed on the conveyor belt bring the abrasive to the top, then put down the abrasive to separator. Using polyester wire core special belt, with the function of high strength, high tensile properties. Pulley use squirrel cage structure, avoiding scattered abrasive embed to the gap between the pulley and belt, affecting transmission. There is 10% design Margin for elevator capacity. Because the hoist falls abrasive by centrifugal gravity, part of the material will fall back into the hoist every time. Therefore, it is necessary to increase the lifting capacity appropriately.
