Summary: A ton of steel shot gone in days - many owners think it is normal wear, switch suppliers, and still burn through it. Mali Steel Shot (Wuhan Hongxin Lixin), 26 years in the trade, points to hardness, roundness and grading as the three parameters to check before blaming a supplier. Get them right and one ton of graded abrasive does the work of 1.3 tons of ordinary shot.

A ton of steel shot gone in days? Mali Steel Shot (Wuhan Hongxin Lixin), 26 years in metal abrasives, hears this constantly. Many owners treat it as normal wear, switch suppliers, and still burn through shot.

Before changing suppliers, check these three things.

1. Hardness - harder is not better

Shot over HRC55 shatters on impact inside the blaster, turns to dust, and gets sucked out by the dust collector. You paid for shot and got dust. Right range is HRC40-50, where impact and wear life balance.

Our shot is centrifugal-granulated with quench and temper, held at HRC42-48, fracture rate under 0.8%.

2. Roundness - irregular shot is money thrown away

Irregular shot bounces around the machine, never strikes the workpiece squarely, and gets discharged as waste by the separator. Good shot needs roundness of 90% or better; ours runs 92%+.

Low roundness has a hidden cost too: roughness comes out uneven, and inspection gets rejected.

3. Grading - single-size shot cycles poorly

With one size only, the gaps between particles fill with dust and blasting efficiency drops. Graded abrasive blends sizes by ratio, so one ton does the work of 1.3 tons of ordinary shot.

FAQ

Q: What is normal steel shot consumption?

A: 8-12kg per square meter for ship blasting. Over 15kg means check fracture rate; usually hardness or roundness is off.

Q: How many cycles does good steel shot last?

A: 3000+ cycles without pulverizing. Cheap shot turns to dust in a few hundred, which makes it far more expensive per ton.

Q: Why is my shot blasting machine consuming shot so fast?

A: Check hardness, roundness and grading in that order. HRC40-50, roundness 90%+, and graded abrasive will bring consumption down sharply.
