Performance and Usage Guide of Vacuum Shot Collector

The vacuum shot collector (also known as shot machine, sand suction machine) is a device used for the recovery, cleaning, and conveying of shot blasting/spraying media. It is widely used in shoting cleaning, sandblasting operation shot recovery, and workshop scrap cleaning, etc.

1. Main Performance Characteristics of Vacuum Shot Collector

1. Core FunctionsShot recovery: Automatically suck back steel shots, aluminum shots, glass beads, etc. after shot blasting/spraying, reducing waste.

Impurity separation: Sep shots from dust, scale, etc. through the filter system, improving shot utilization.

Quick cleaning: Suitable for ground cleaning of shot blasting rooms, sandblasting workshops and foundry workshops, improving work efficiency.

2. Main Technical Parameters

Parameter Typical Range Description

Shot collection capacity 500-5000/h Depending on power and nozzle design

Vacuum 15-30kPa (up to 50kPa for high-pressure type Affects shot collection efficiency

Motor power 3-30kW Small machine 3-7.5kW, industrial grade 15-30

Storage bin capacity 0.2-2m³ Affects continuous operation time

Filter method Centrifugal separation filter drum/bag Ens dust does not enter the fan

Applicable shot type Steel shots, stainless steel shots, aluminum shots, ceramic shots, etc. Need to match nozzle material

3 Advantages

Energy saving and environmental protection: Reduce shot loss and lower production costs.

High degree of automation: Can be paired with conveying systems to achieve automatic reuse

Flexible mobility: Some models have wheels for flexible use within the workshop.

2. Typical Application Scenarios of Vacuum Shot Collector

Shot blasting workshop

Recover the shots thrown out by the shot blasting machine, reducing manual cleaning.

Suitable for use with lifting hook type, passage type, and track type shoting machines.

Spraying operation

Recover the abrasive (such as steel sand, copper ore sand, etc.) after sandblasting.

Foundry

Cleaning residual sand particles and shot mixture on castings.

Ground cleaning

Quickly clean up scattered shots, metal chips, etc. on the workshop floor.

3. Key Points of Usage of Vacuum Shot Collector

1. Operation process

Check equipment: Ensure filter drum is not blocked, and pipes are not leaking.

Ad nozzle: Select the appropriate nozzle according to the shot size and accumulation (wide mouth nozzle is suitable for large particles, narrow mouth for fine recovery).

Start equipment Turn on the fan first, then turn on the shot collection function to avoid blockage.

Monitor recovery: Observe the storage bin and filter system to prevent overload.

Shdown cleaning: Clean the filter drum after shutdown to avoid dust affecting the next use.

2. Maintenance and Care

Regularly clean the filter drum: Prevent blockage suction (it is recommended to check once every 8 hours).

Check pipe wear: Metal shots may wear out soft pipes, and need to be replaced regularly.

ubricate fan bearings: Add grease according to the requirements of the equipment manual.

Check the electrical system: Avoid motor overload or line aging causing faults.

3. Issues and Solutions of Vacuum Shot Collector

Issue Possible Cause Solution

Insufficient suction Filter drum blocked/pipe leakage Clean filter drum check seals

Low shot recovery rate Unreasonable nozzle design Replace with a suitable nozzle

Noisy equipment Worn fan bearings Replace bearings or lubricate

and impurities mixed Separation system fault Check cyclone separator

4. Sizing Suggestions

Choose according to shot type:

Steel shots/cast steel → Standard type (wear-resistant pipeline).

Aluminum shots/glass beads → Anti-static type (to avoid adsorption and blockage).
