Problem Description:

Our customer is a market leader in the supply of bulk solar salt, based in the north west region of Western Australia. The sale it a wet material when harvested, with relatively small particles of less than .16” (4mm). When conveyed, the salt has a tendency to hang up in the chutes, skirts and screens. As the salt is highly corrosive, it causes problems for regular mild steel materials handling components.

The customer was experiencing a significant spillage problem around the transfer point area. Here the challenge was to contain the low mass salt particles effectively and stop them from bouncing off the belt. Due to salt causing hang up, fitting any type of skirting around the chute had not been successful previously.

Not only was there wasted product, but the steel structure of the transfer point was quickly being affected by an increasing amount of corrosion caused by the salt. To maintain this area, it needed to be washed down frequently, creating additional labor costs.



After consultation with our Australian distributor, the Snap-Loc Dust Seal was selected as a better dust suppression solution. Snap-Loc is made from high quality engineered polyurethane, making it very lightweight and easy to install, requiring minimal labor. Also, because it is highly durable and resistant to corrosion, it will last longer once in place, requiring less replacement skirting in the future. This will achieve significant cost savings and reduce scheduled maintenance shutdowns.

The customer has confirmed that the Snap-Loc Dust Seal System was very easy to install:

“only required measuring and some welding of the stainless unistrut and did not require knocking down of skirts and adjustment. Kinder & Co. provided lots of assistance in getting quotes, drawing, supplying offcuts of material from the warehouse and working wit us to get our requirements right (stainless steel unistrut instead of the standard mild steel in stock).”
