Mineral processing technology company Haver & Boecker has launched to the Australian market its Niagara Scalper screening system.
High wear rates on crusher parts, limits on feed rates, and issues with product quality can plague mineral processing, building materials and recycling operations; impacting costs and productivity.
The system is suitable for screening and scalping coarse material, and moist and sticky material with a tendency for screen blinding and pegging. It is well suited to operations with high feed rates and those with discontinuous feed rates.
Other features include a drive system which generates a constant circular vibration with a fixed amplitude, regardless of feed material loads and conditions; distinctive four-bearing design with eccentric shaft acceleration which is essential for load-independent operation, ensuring screen blinding or clogging won’t occur; and counter weights on the shaft: in combination with the support buffers, the weights balance the system to dynamically minimise loads.
The system is available in single and multiple-decks designs with deck sizes ranging from 1200mm to 2700mm in width, 2500mm to 8000 mm in length and capacity of up to 3000 tonnes per hour. The maximum feed block size is 2000mm x 1000mm x 1000mm (depending on model) and it can screen cut sizes from 16mm to 350mm.
