Shot Blaster

How to choose. These are not five machines of different technology; they are one machine in five widths, and the choice is decided by access and area before it is decided by output.

• YD200 (160 kg, 400 mm body) is the only model two people can carry. Its value is not output but reach: lifts, service ducts, gaps between equipment and edge finishing are where a 550 mm machine physically cannot go. Where a client buys for open floor and edges together, the usual combination is one wide model for the main run plus a YD200 for edges, rather than a YD200 alone covering the whole floor.

• YD270 (335 kg) is the compromise when manual handling is no longer possible but the area is still modest. Above roughly 1,000 m² it is more economical to step up to the 550.

• YD550 and YD600 share the same 29 kW and identical overall dimensions, differing by 50 mm of width and 30 m²/h. The deciding factor between them is not the 10% output but whether the plant room, goods lift and doorway admit a 720 mm body.

• YD800 (980 mm body, 770 kg) is the bridge-deck and large-plate model. It needs a clear passage of at least 1.2 m and a forklift or crane on site.

Predicting output. Productivity figures are for an unobstructed run, so an overlap allowance has to be applied before computing a shift: about 1.35 at 600 mm width and 1.25 at 800 mm. A YD800 at 450 m²/h therefore covers roughly 2,900 m² in an eight-hour shift, not 3,600 m².

Where a Shot Blaster Pays for Itself

• Bridge deck waterproofing. Removing laitance and opening the surface before the membrane goes down, on decks that cannot be brought into a workshop.

• Plant, warehouse and car park floors. Floor renovation and coating removal on large slabs where the machine can run continuously and the only labour is the operator.

• Runway, apron and highway surfacing. Line marking removal, asphalt bleeding treatment and skid-resistance restoration, done at night without closing the whole surface.

• Steel plate and tank bottoms. Mill scale and coating removal on plate and storage-tank floors where the surface is horizontal and reachable.

• Concrete scarifying and anti-slip work. Creating the profile that a topping, screed or anti-slip coating needs to bond to.

  
  

Surface Profile and Acceptance

Concrete work is accepted against the ICRI Concrete Surface Profile scale, normally CSP 3–7; steel work is accepted against Sa 2½ (ISO 8501-1). Which end of the CSP range is reached depends on three settings the operator controls — steel shot size, travel speed and the number of passes — so the grade is specified first and the machine set to it, not the other way round. On a floor where a coating supplier has named CSP 4, that is the acceptance criterion, and the trial area is where it gets proven before the full run starts.

• e 35–60 days after receipt of order for standard configurations; non-standard voltage and export crating are scheduled separately.

• Quotation scope complete set — blast system, dust collection and the wear parts configured for that model. Freight, insurance, duties and third-party inspection are excluded.

• Installation not included; quoted at USD 135 per man-day, overseas travel borne by the buyer. Self-installation is supported with remote guidance and does not affect the warranty.

• Warranty 12 months from the final acceptance certificate, normal wear parts excluded. Two years of wear parts are recommended on site.

• Response quality issues answered in writing within 24 hours; engineers dispatched within 7 working days of a written request.

• Voltage built to the destination standard; motor selection confirmed in writing at order.
