The First Rock Salt Mine in Canada

 

 

MILL

The skip is automatically dumped at the deck head - half of the load going to each of two grizzlies situated at each side of the shaft. The coarse lump salt passing over the grizzly goes to two steel picking belts, 30" wide by 20' long, where it is hand picked, 2 men to each belt, and a fourth taking the rejected salt to the dump. The remainder going directly to a Jeffrey 30" single roll crusher operated directly from line shaft. The salt passing through the grizzly is passed over a 5 mesh vibrating screen. The salt passing through this screen is used for hay salt or used for brine making. The salt passing over the screen is hand picked and goes direct to the mill circuit joining the salt from the Jeffrey crusher in an elevator. This is elevated to the top of the mill and is passed over two 3 mesh vibrating screens. The oversize goes to a set of Cornish Rolls, 14" x 24", and then returned to the aforementioned elevator. The salt passing through the 3 mesh screens is passed over two 4 mesh screens. The oversize constitutes the product called "3 mesh" or "Refrigerator Salt" and, is fed to an 18" trough conveyor belt which discharges at the bagging platform in the main warehouse.

The salt passing through the 4 mesh screen is passed over Rotex 26 mesh screens to remove the fines which go to the ponds for brine making. The salt passing over the Rotex goes to the 18" trough belt to bagging platform. This is "5 mesh" or "Fishing Salt"
