New dimensions with the NIAGARA T-CLASS®

At bauma 2007 HAVER & BOECKER introduced the prototype of the new HAVER NIAGARA T-CLASS®. This machine design has since been used continuously and developed further. Today the company looks back on a large number of satisfied customers worldwide.   HAVER & BOECKER recently introduced the NIAGARA T-CLASS® with a newly designed drive system, allowing more amplitude/rotary speed combinations than before. This in turn allows small cut sizes to be realized as well as difficult classifying jobs with large cut sizes. Further, the machine is equipped with a newly developed wear-protection system decreasing the replacement time of worn elements, thus reducing downtime.   Within the scope of the NIAGARA T-CLASS® concept, screening machines with widths starting at 2.40 meters were built in the first phase of expansion. After the introduction of a time and cost-saving modular construction system, machines with screen decks of almost twice the width (i.e. up to 4.20 m) can be built today at the plant in Münster.   A recently built 3.5-deck model D180 3000 x 7200 machine of this type was sold to German engineering and plant designer HAZEMAG in Dülmen. It separates 450 tons of limestone per hour at 25/15/8 and 4 mm. The dimensions of this screening machine are 3 m x 7.2 m, and the total screening surface amounts to 72 m². It weighs about 25 000 kg. In order to achieve the throughput and cut sizes requested by the customer, the NIAGARA T-CLASS® is equipped with two...
