FROM THE GOOD EARTH TO THE PALLET—Process, See Below

Newmont Slate maintains quarries of large acreage with ample deposits of fine quality stone. Newmont Slate quarries, manufactures and sells roofing slate directly to clients with direct access and added convenience. Newmont Slate upgrades plant machinery and engineers equipment from the ground-up to maintain efficient production and timely delivery. Below, is a composite of Newmont Slate’s production process.

(L) General quarry activity from drilling and extracting, to transporting raw stone to the plant for processing.

(R) Backhoe extracting slate slabs from the quarry wall.

(L) The slabs enter the plant on custom conveyers equipped to carry large tonnage.

(R) The slabs are cut evenly into various sized blocks with a water cooled diamond saw.

(L) Blocks of slate are moved to the splitting area where every slate is hand-split to specifications.

(R) After the slate blocks are split into individual slate, each side is trimmed to size.

(L) Each slate is punched two holes at a time, to accommodate the roofing nails. This process bevels the holes allowing nails to be countersunk.

(R) Daily, plant machinery is repaired, continuously upgraded, or built from the ground up through adaptive and creative engineering which maintains efficiency and quality production.
