How much does an industrial shot blasting machine cost?

Quotation

What drives the price and what data we need to quote

An industrial shot blasting machine has no list price: it is quoted for the part it has to blast. A tumble belt machine for small parts, an overhead conveyor tunnel for welded structures and a robotic blast room are very different machines, and even within the same line the cost changes with size, output and equipment. Below we explain what drives the price and what data we need to quote.

What drives the price

• The type of machine. The part and the process decide it: wheel blast, when the part goes into a machine in series production; compressed air, when the part is very large, very varied or only one area has to be blasted. See our wheel blast machines and air blast equipment.
• Part size and weight. They set the passage section of the blast cabinet, the load per hook or per cycle and the length of the conveyors.

• Output. Parts per hour or tons per shift decide between a batch machine and a continuous-pass machine.

• The blasting system. The number and power of the blast wheels, or the number of nozzles in an air blast system, depending on the surface to cover and the feed speed.

• The dust collector. It is sized for the airflow the blast cabinet needs. See our cartridge dust collectors.

• Automation and integration. Variable speed drives, PLC control, robots or manipulators, automatic loading and unloading, or the connection to an existing paint line.

What data we need to quote

• A drawing or a photo of the part, with its dimensions and maximum weight. If the parts vary, the largest and the heaviest one.
• The material and the surface condition: rust, mill scale, foundry sand or old paint.

• The expected output: parts per hour or tons per shift.

• The finish the next process requires, for example the surface preparation grade for painting. See What surface preparation grade do I need?

• The plant's voltage and frequency, and the available space.

With that data we prepare a technical and commercial proposal. Contact us.

Do you build custom shot blasting machines?

Yes. Each CYM line (tumble belt, spinner hanger, rotary table, roller conveyor for structures, overhead conveyor tunnels) has a defined design: the blast wheels, the abrasive recirculation and cleaning system, the wear linings and the dust collector. On that basis we adjust what the customer's part requires: the passage section, the number and position of the blast wheels, the length of the conveyors, the electrical supply or the integration with the line. And if the part or the process does not fit any line, we design a new machine from scratch.

Two examples of adjustments to a standard line:

• The tunnels at Truper, in Mexico have a narrow, tall passage section, smaller than the catalog models, designed for hanging tools.
• The machine at Leon's Powder Coating, in California is a standard model, the EST-ROD 16X21, built for 480 V / 60 Hz, with a control panel built to UL standards and 40 ft of conveyor on each side.

Starting from a defined design has one advantage: the machine is already running in other plants.

Do you support commissioning outside Argentina?

Yes, in any country. A CYM technician travels to the plant, supervises commissioning and trains the operators on operation and maintenance. Installation can be done by the customer's staff, with our drawings and instructions, or by us, with a CYM technician and crew. That is how we have worked in Argentina, Mexico, Colombia and the United States: see our success stories.

After delivery, spare parts. Our blast wheels share a standard design across all our machines, so their wear parts ship immediately. Other replacement parts are specific to each model and are made to order; that is why we suggest a spare parts kit to keep in stock with the machine.

Wheel blast or compressed air?

It changes the machine and also the cost. Wheel blasting suits series production, with parts that go into a machine: it throws a lot of abrasive with little energy. Compressed air, with blast pots, blast rooms or cabinets, suits very large or very varied parts, blasting just one area or working on site. The difference is explained in Wheel blast or compressed air: what is the difference?.
