Screen gravel, road metal and drainage stone
On-site aggregate screening in New Zealand — oversize out, saleable grades in, less haulage both ways.
Road metal, pea gravel, septic stone, drainage rock and recycled concrete all need a defined product size. Site Machinery NZ supplies DeSite Proscreens and Static Grizzlies so contractors and yards can grade aggregate on the job instead of buying every tonne in.
Road metal, base and drainage
Use square mesh for clean gravel and road metal grades; elongated openings when you want throughput on mixed feed. Pair a Static Grizzly for oversize with a Proscreen for the finished fraction — the same dual-pass idea farmers use for cow-race filling, scaled to civil aggregate.
Grizzly first, then finished product
Knock cobbles and sticks on a no-power Static Grizzly, then run a vibratory Proscreen for pea stone, septic rock or base metal. Change mesh in minutes when the job shifts from drainage stone to driveway metal.
