US manufacturer to show latest washing and screening equipment at Hillhead 2018
Superior Industries Inc., the US-based manufacturers and global suppliers of bulk material processing and handling systems, will be showing several new products on stand CE16 at Hillhead 2018, including their Alliance low water washer, Spirit modular sand plant and Guardian horizontal vibratory screen.
A first of its kind for aggregate producers, the Alliance low water washer is capable of accepting dry fines directly within a crushing circuit. During operation, an agitator section accepts the feed where it is mixed with water to produce thick slurry. This is fed on to a dewatering screen with a series of spray bars to help clean and wash out the fines. The end result is saleable manufactured sand with just 8% moisture content.
The Alliance low water washer is designed specifically for washing crusher fines and is said to uses 80% less water than the traditional sand screw/screen combination. Superior manufacture various models of the washer for rates up to 272 tonnes/h, although custom-designed machines can produce higher rates if required.
The new and flexible Spirit modular sand plant merges Superior’s Helix cyclone, dewatering screen, sump tank and slurry pump into a single plant capable of sand production, fines recovery and dewatering.
According to the company, the brand new Helix cyclone is specially designed with a geometrically efficient inlet to boost performance and reduces internal component wear. In addition, all wetted surfaces are lined with cast polyurethane for extended performance and life. The high-tonnage dewatering screen is capable of removing all but 8% moisture content, meaning the sand produced is immediately saleable.
For sand production applications, Spirit sand plants are available in five models offering production rates up to 300 tonnes/h from the dewatering screen, whilst seven ultra-fines recovery models offer rates from 20 to 161 tonnes/h.
On show for the first time in Europe, the Guardian horizontal vibratory screen with its triple-shaft, adjustable oval stroke design is new processing solution for the aggregates industry. According to Superior, the machine has several key features that help to distinguish it as a unique horizontal screen, including:
- Patent pending bottle jack lifting points to simplify and speed up spring replacement and improve safety (no crane required)
- Segmented belt guard and tailgate sections that require only one person to remove and replace for maintenance
- Bolt-locking, hinged access doors that allow access for screen media maintenance and prevent operators from misplacing the spillage-preventing doors
- A fully enclosed belt guard for maximum safety plus an integrated on-board motor belt tensioner for speedier maintenance.
Superior design and manufacture the Guardian horizontal screen in two-, three- and four-deck configurations in 5ft x 16ft, 6ft x 16ft, 6ft x 20ft, 7ft x 20ft and 8ft x 20ft models. Each unit is equipped with spray-bar knock-out holes for quick conversion to wet processing applications.
