Q03210B Shot Blaster | 600kg Automatic Loading/Unloading Tracked Shot Blasting Machine | Surface Descaling & Sand Removal System for Small-to-Medium Castings and Forgings

1. Product Overview

This tracked shot blasting machine uses a shot blaster to throw high-speed shots continuously onto workpieces tumbling on the track, achieving cleaning purposes. Equipped with an automatic loading/unloading mechanism (1T chain hoist), it is suitable for surface treatment of small-to-medium castings, forgings, stampings, gears, springs, and other workpieces – removing sand, rust, oxide scale, and burrs. Typical applications include high-volume, automated cleaning production lines in machine tool factories, automobile factories, textile machinery factories, and heat treatment workshops.

2. Industry Challenges & Root Cause Analysis

Low cleaning efficiency and high labor dependence:Traditional manual or semi-automatic shot blasting relies on operators for loading/unloading – low efficiency and high labor intensity. Root cause: lack of automatic loading/unloading mechanisms and continuous operation capability.

High shot consumption and operating costs:Traditional shot blasters have irrational structures – uneven shot distribution and low ejection speed – poor cleaning results requiring repeat operations. Root cause: outdated blaster design and frequent blade replacement.

Non-compliant dust removal:Cleaning generates large amounts of dust – traditional bag filters have low filtration accuracy and excessive emissions. Root cause: large filter media pores and outdated cleaning methods.

Frequent wear parts replacement and high maintenance costs:Short service life of track plates, blades, and protective plates – frequent replacements increase downtime and maintenance costs. Root cause: improper material selection and insufficient wear-resistant structural design.

Low automation and weak process control:Shot blasting time and shot flow depend on manual settings – poor batch consistency. Root cause: lack of programmable control and process monitoring systems.

3. Solution

3.1 Efficient Automatic Loading/Unloading System:1T chain hoist with automatic loader – max load 600kg. Workpieces loaded into hopper then automatically dumped into cleaning chamber – cleaning program starts after front door closes – automatic discharge after completion – single operator for multiple machines.

3.2 High-Efficiency Dual Shot Blaster System:Two Q034 high-efficiency curved blade shot blasters – 11kW each – shot blasting volume 200kg/min – ejection velocity 80m/s. Compared to traditional models: projectile velocity increased by 30% – cleaning time reduced 30-40% – efficiency increased ~100% – blade replacement only 5-6 minutes – energy saving 30% – noise reduced 6-7dB to below 90dB. Blade special design (thicker outside, thinner inside) with specific heat treatment – service life ＞500 hours.

3.3 Pulse Cartridge Dust Collector:Designed and manufactured with advanced environmental protection technology – submicron ultra-thin fiber layer on filter media – filtration accuracy 5μm – dust removal efficiency ≥99% – emission concentration far below national standards. Folded filter media with filtration area 30-40 times traditional bags – more compact, lower resistance, excellent cleaning regeneration.

3.4 Wear-Resistant Rubber Track & Long-Life Wear Parts:Specially made wear-resistant rubber track plates – significantly extended service life – reduced replacement frequency and maintenance costs. Perforated track allows shots and debris to fall through into screw conveyor – elevator sends to separator for recycling.

3.5 Three-Stage Air Separator:GF Switzerland technology – three-stage separation function (pure shots, mixed shots, shot-dust mixture). After separation, pure shot sand content ＜1% – qualified shot content in waste ＜1% – effectively reduces shot waste and operating costs.

3.6 Manual Control System & Safety Interlocks:Manual control – simple and intuitive operation. Spacious maintenance door with safety interlock switch – shot blaster only starts after door closed. Anti-misoperation device and emergency stop button.

5. Selection Guide

5.1 Recommended Scenarios

• High-volume shot blasting cleaning of small-to-medium castings, forgings, stampings

• Oxide scale removal from gears, springs after heat treatment

• Production requiring automatic loading/unloading with single operator for multiple machines

5.2 Key Selection Considerations

1. Workpiece size and weight: Verify single piece ≤30kg, length ≤300mm, total batch weight ≤600kg

2. Cleaning efficiency: Shot blasting volume 200kg/min – calculate against daily output requirements

3. Shot selection: User to procure shot media, granularity 0.5-1.5mm

4. Dust removal requirements: Cartridge filter meets national emission standards – regular ash cleaning maintenance

5. Utilities: User to supply 3-phase 380V/39kW power and 0.5-0.7MPa compressed air

6. FAQ

Q1: What cleaning results can be achieved?

A: Q034 high-efficiency curved blade shot blaster – ejection velocity 80m/s – shot blasting volume 200kg/min – uniform shot distribution with wide coverage – effectively removes sand, rust, oxide scale, and burrs with stable, consistent cleaning quality.

Q2: Is blade replacement convenient?

A: Q034 blaster uses dovetail-type fixed clamping – blade replacement takes only 5-6 minutes – no special tools required – significantly reduces maintenance downtime.

Q3: How are shots recycled?

A: Shots and debris fall through track perforations into screw conveyor → elevator → three-stage air separator (pure shots, mixed shots, dust) → qualified shots return to shot hopper → blaster for recycling – high separation efficiency – minimal shot waste.

Q4: What emission standards can the dust collector achieve?

A: Pulse cartridge dust collector – membrane polyester filter cartridges – filtration accuracy 5μm – dust removal efficiency ≥99% – emission concentration far below national industrial "three wastes" standards.

Q5: Can the equipment achieve fully automatic operation?

A: Equipped with automatic loading/unloading mechanism (1T chain hoist) – workpieces dumped into cleaning chamber after hopper loading – cleaning program starts after door closes – automatic discharge after completion. Manual control – simple operation – single operator can manage multiple machines.
