What operators say about DeSite
Feedback from DeSite operators about the machines — build quality, production and durability. Local NZ pricing and freight are separate.
“I have the DeSite 78 and can do 30 to 35 yards an hour with my 3 yard loader. I have done hundreds and hundreds of yards of topsoil in the last 3 years with zero problems with it. Great working screener for small operators in my opinion.”
“Using my 108 almost everyday. Making 1 inch minus soil fill blended with aged compost and mushroom soil. Screen works awesome and the material it makes sells itself.”
“I've had one for 8 years. Zero maintenance and has never let me down. Has been a great investment.”
“It paid for itself in 3 weeks of selling soil. Then I ran it for another 4 years… Then sold it for 75% of what I paid for it.”
“Absolutely love the SLG 78! Absolutely changed the business! Only wish is that I had gotten the SLG 108!!”
“The screener is a “no joke” piece of equipment. Too bad folks can't see one in person to see the quality before they decide to get one. The pictures and videos don't show how well built it is.”
Need Graded Material On-Site?
Topsoil, Gravel and Aggregate Screening
DeSite screeners grade topsoil, gravel and aggregate on the job — from compact 68s through to full-size 108s, plus no-power static grizzlies for oversize. Separate oversize from usable stone, soil and aggregate to make clean fill, road base and stockpile material that matches the spec you need.
Built for earthmoving, civil, quarries, landscaping and material yards. Operators also use them to cut tip fees, reduce buy-in, and turn leftover material into saleable product.

Profit Calculator
Estimates assume about 50% of screened material becomes saleable product. Actual results vary with material type, moisture, mesh and setup.
Illustrative example only: a dual-78 setup (grizzly + soil screen) with large buckets can model $900+/hour revenue under optimal conditions — not a guaranteed income figure.
Range: $20 - $45 per m³
🎯 Optimal Setup Example
Dual 78 Setup: Grizzly screen (oversize removal) + Standard soil screen (60x20mm mesh) for maximum production
Illustrative dual-78 example: under optimal conditions this setup can model $900+/hour — results vary; see calculator assumptions below.

* Calculations assume 50% of screened material becomes saleable product. Actual results may vary based on material type, market conditions, and setup configuration. Dual screen setups (grizzly + standard soil screen with 60x20mm mesh) can significantly increase production rates and revenue potential.
How much can a soil screener produce?
Typical DeSite Proscreen rates for New Zealand operators: SLG-68V about 15–20 m³/hour, SLG-78 about 15–25 m³/hour, SLG-108 about 25–40 m³/hour — depending on mesh, moisture and feed. Use the calculator above with your bucket size and price per m³.
Is screening cheaper than buying graded topsoil?
If you already own dirt or gravel on site, screening often costs less than buying screened product in and trucking oversize away. Factor tip fees, haulage both ways, and the saleable fraction (the calculator defaults to about 50%).
Screening gravel vs buying aggregate
Contractors and yards use Proscreens and Static Grizzlies to grade road metal, drainage stone and recycled concrete from material already on the job — see gravel and aggregate screening.
