Comparing shot blasting machine quotes? Use this 7-point checklist to check specs, wear parts, power use, warranty, and total cost before you buy.
Two quotations for the "same" machine can differ by several lakh rupees. The cheaper one often costs more by year three.
Compare quotations on total cost of ownership, not the headline price. Check the technical specification, wear parts, power use, build quality, after-sales support, and commercial terms line by line.
Why the Lowest Quote Often Costs More
Suppliers price machines differently. One includes a dust collector. Another lists it as an extra. A third uses thinner liners to cut the price.
You only see these gaps when you compare quotes side by side. So build a simple comparison sheet before you shortlist anyone.
Your 7-Point Quotation Checklist
1. Machine Type and Size
Confirm the model suits your components. Hanger, tumblblast, spinner hanger, roller conveyor, and table type machines each suit different parts.
Check the cabinet size, maximum load, and part dimensions. A machine that is too small slows your production.
2. Blast Wheel Details
The blast wheel does the real work. Ask for:
- Number of wheels and motor power (kW)
- Wheel brand or in-house design
- Throwing speed and abrasive flow rate
More power is not always better. Match it to your part size and cleaning target.
3. Wear Parts and Liner Material
Blades, impellers, control cages, and liners wear out first. Ask which material the supplier uses, such as manganese steel or high-chrome alloy.
Then ask for the expected life in working hours. Vague answers are a warning sign.
4. Dust Collector and Separator
A good dust collector protects workers and meets pollution control norms. Compare the airflow (m³/hr), filter type, and filter area.
Check the abrasive separator too. Poor separation raises abrasive consumption and damages surface finish.
5. Power and Abrasive Consumption
Ask for the total connected load. A lower load means lower electricity bills every month.
Also ask for the expected abrasive use per hour. These running costs add up faster than most buyers expect.
6. Build Quality and Safety
Look at plate thickness, welding quality, door interlocks, and electrical panel make. Ask for branded components such as Siemens, ABB, or Schneider where relevant.
Check that the quote lists safety interlocks and emergency stops.
7. Commercial Terms
Read the fine print on:
- Delivery and installation timeline
- Warranty period and what it covers
- Payment terms
- Spare parts availability
- Training for operators
Ask whether installation and commissioning are included in the price.

Use a Simple Comparison Checklist
Prepare a comparison sheet and evaluate every supplier against the same requirements.
| Evaluation factor | What to verify |
|---|---|
| Technical suitability | Capacity, dimensions, machine configuration |
| Total purchase cost | Equipment, installation, transport, taxes |
| Productivity | Expected cycle time and output |
| Operating expenses | Power, abrasive, labour, maintenance |
| Spare parts | Availability, cost, delivery time |
| Support | Warranty, training, commissioning, service |
Final Takeaway
A good quotation is clear, detailed, and complete. Compare technical specs first, then running costs, then terms. Choose the supplier who answers your questions openly.
