Focus on an application


Every month, this section will try to look closer at one of the many applications where shot blasting is involved, and what Wheelabrator Abrasives products & services can add to your manufacturing.


December 1999 : Surface Preparation Applications   

Operating mix must be maintained through controlled operational practices.  Practices are invalid if mix is not consistent batch after batch.

Wheelabrator Abrasives abrasives meet or exceed every aspect of SAE and SFSA specifications.  Our ISO 9002 Registration assures consistency in our manufacturing process.

Our proprietary process adds no cosmetic chemical coatings such as nitrates or chlorides.

Low chloride levels ensure low conductivity of our abrasives.  High salt or chloride levels means high conductivity, which results in a higher corrosion rate.   The substrate degrades and the coating fails.

Proper and scheduled maintenance combined with accurate settings must be maintained in order to produce controlled procedures.

Training is provided to operators and maintenance personnel at no charge. Additionally, a Statistical Process Control (SPC) computer program for the blast operation is also available.

The statistical process control involves :

  • Setting and maintaining the blast pattern for the product.
  • Monitoring the volume of abrasive thrown.
  • Adjusting the separator to remove scale, spent abrasive and contaminants.
  • Monitoring "fines" in the mix which will reduce failure caused by back-side contamination.
  • Regulating the dust collector and removing other fines and dust. 
  • Performing record keeping by monitoring:
  1. Operating mix profile               
  2. Horsepower utilization
  3. Abrasive additions vs. consumption
  4. Processing times to ensure optimum cleaning in minimal time
  5. Surface area cleaned vs. pounds of abrasive used
  6. Parts life and maintenance vs. products cleaned

Following the above SSPC ensures maximum effectiveness and measures cost and efficiency.

Wheelabrator Abrasives technical support and quality abrasives will have a positive affect on every aspect of the blast operation costs. The price difference between a quality abrasive, supplied with technical support, and a cheap (lower price) abrasive is insignificant in light of the overall blast cleaning cost savings.
