Glengarry Quarry Manager for Burkett Aggregates explains how to get the best out of screens and crushers.
He has been supplying 40mm crushed for wind farm job in Hawkes Bay, and drawing out the 15mm sand.
Gavin tends to overrun the K4 screen so that there is fines going into the crusher to help crush down the all the smaller stone. This then feeds the stacker which Gavin mentions how this frees ups a the loader for moving sand and loading trucks.
“Had the stacker an hour for about twelve months, and honestly it's become like my best friend, it's freed up our to drivers a lot. It pretty much does the job of a whole loader.
We've got 45 truck and trailer loads per day... so we need to be moving this product, this machine, it's got very high output, so it helps a lot.
We're getting 200 ton an hour of the 40mm product and 150 ton an hour of sand. It's a three hundred and fifty ton an hour into the whole setup altogether. so you don't have to worry about running out of material. All you have to worry about is putting the stuff in, having enough material to put in the setup.
Anyone else is looking at, getting into a quarrying, this is the gear to get. I was always wondering what it would be like. It hasn't been around for years, but the proofs in the pudding, this setup here has gone hard for 12 months now, running it in tough conditions...and its stood up.
I'm regularly checking everything, going around all my scrapers, rollers, belts are in-line. Then as soon as it sort of seems like everything's sweet, then I can just let it eat, and it just it just eats, it pumps out material.
We're always going to have teething issues. Equip2 to have always been on the ball, I ring them straight away. They're usually here the next day or they talk to me on the phone on how to resolve the issues.”
In summary Gavin says “the output's ridiculous.”
