In calculating the value of blasting, a lot of blasters make a usual mistake that is to think about the value of abrasive media only. There are a lot of factors to think about the cost, some factors are not including as obvious in calculating the truth value. Even when the various blasters think about the relevant factors of blasting, they generally think about the cost of every factor separately. What could also take no notice is that the interplay of the varied factors of cost.

Abrasive media Cost:

Lots of blasters mainly focus on decreasing this value and this is the foremost visible cost. However, a less expensive abrasive may result in a rise in other costs like follows:

• A softer abrasive may end in a long time to blast which cause the labor and equipment running cost riced.
• A dustier abrasive could end in poor visibility and a poor finish requiring rectify. If we applied a coating on a poorly prepared surface, it might end in a good higher value.
• More use of abrasive media leads to more disposal costs albeit it’s cheaper.
• A less expensive media might not be as clean and therefore the unclean surroundings may end in compromised operator vision, accidents and workplace safety, and environmental fines.
• Various blasters make the common mistakes that are of using the coarse abrasive when they could get better results by using the finer abrasive. This abrasive will have the great impact on per unit of volume. If the stream has more particles then it will blast more surfaces at an equivalent time. As an example, rather than employing a hard, costly abrasive, or coarse particle, crushed glass is often an honest choice for work on relatively smooth and soft surfaces like wood or concrete.
• The acquisition cost inclusive of all freight, warehousing, and delivery to the worksite should be the value of the abrasive media.

For the desired surface profile it’s very important to settle on the proper abrasive counting on the surface being blasted, this is the key to achieving an enduring coating for any application. Any blaster can get the work done faster with the proper abrasive media. The minimum use of abrasive media gets the maximum profit.

Abrasive Flow Rate:

• For getting the specified surface profile on the substrate, use a higher amount of abrasive flow. A waste of media at the end of an excessive flow whereas it fails to realize the specific profile in the result of a lower flow and wastes the labor cost and equipment time.
• With the use of proper equipment, you are able to do to fine-tune the flow precisely to the specified level.
• The amount of media used per hour of continuous blasting is the method of calculating the flow rate.

Cost of disposal of used abrasive:

The component of cost which is mostly ignored in calculating is that the disposal cost of used blast media.

The cost of disposal depends on different factors like the disposal costs including dumping fees, taxes, labor to pack, freight, and packing. Calculate the disposal cost by adding these factors to it.

Labor cost:

The labor wages are mostly calculated on the basis of the hours such as the hourly rate of blaster plus a proportion of wage overheads which are the meal breaks, leave, training, and non-productive time plus direct supervision time.

Equipment Running Cost:

In this factor, we calculate the value of owning and running the equipment which are blast equipment, compressor, and vehicle, rental, maintenance depreciation, and running costs including consumables like fuel, antioxidants.

At last, to calculate the charge out rate per square meter handover the customer adds an appropriate level of margin to your cost budget. And compared it with the other competition charge out rates simply to make sure to reach the optimal charge out rate.
