Blast-One Weekly Tips
Tip #87
Increase your productivity by up to 20% by managing your daily metrics

We’ve been told by every management consultant that having the correct daily KPI’s or metrics is key to having a successful business.

The question remains - what actions or specific behaviors do you take from the KPI’s/metrics?

1. The % of hours blasted
  1. It is important that the hours actually blasted is taken directly from blasting time clocks, not based on estimates. Be accurate with this information.
  2. By measuring this number you will find that your ‘nozzle on hours’ will increase, simply because they are being measured.
  3. This will allow you to set standards and expectations for your blasting crews and monitor improvement targets.
  4. You will probably find a good day is only 65% actually nozzle on time.
2. Abrasive Consumption
  1. This is measuring how much abrasive that you use per sqft or sqm of surface blasted.
  2. If you are using a bulk blaster, the most accurate measurement is how much you added to the pot each day, no-one can accurately calculate howmuch is sitting in the bottom of the pot. After a week of blasting, it will average out.
  3. A high consumption number will tell you:
    i. Are the metering valves open too far – normally means you have a moisture problem
    ii. You are dealing with a very tough coating
    iii. You may want to check what size abrasive you are using and if blasting is the correct method to remove the lining.
  4. You will also be able to accurately estimate if you have enough abrasive and when to order the next load from Blast-One!
  5. Normal Range: Garnet 1-4 lbs/sqft or Slag 7-10 lbs/sqft
3. Blasting Speed
  1. This is telling you how many sqft are actually blasted in 1 hr of “nozzle on time”
  2. After a few days, matching this number up with the % of hours blasted will allow you to plan how many days you will need to be on-site, how long you will need to rent equipment for and allow you to plan to dodge the rain days. (ie: if you only have two days left to blast after the weekend and its going to be raining, work the weekend and give your guys the rain days off instead!)
  3. Its hard to specify a “normal range” for blast speeds but we will attempt it as a guide for you.
    Substrate B1 Garnet 12/40 Slag
    NewSteel – flat steel 200-400 sqft/hr 75-150 sqft/hr
    NewSteel – medium complexity 100-200 sqft/hr 50-100 sqft/hr
    30 mil coating – flat steel 100-200 sqft/hr 60-100 sqft/hr
    30 mil coating – medium complexity 75-150 sqft/hr 50-100 sqft/hr

4. Average Nozzle Pressure
  1. Your pressure is normally the #1 key to productivity in the blasting arena and must be measured with a hyper dermic needle within 6ft of the blast nozzle.
  2. This needs to be measured when all blasters are running, and any other equipment that use air. (paint pumps, air tools, blast helmets etc.)
  3. Any equipment decisions need to be subservient and prescribed to ensure adequate nozzle pressure.
  4. On most industrial painting projects you will always want 105psi as a minimum.
