Vibrating screen is a help to niche applications

 

Maximus Crushing & Screening has introduced two new heavy duty tracked vibrating screens in the shape of the 17 tonne two deck 409 and the 38 tonne three deck 522T.
According to the company, the 409 has been developed to meet the needs of smaller customers who require versatility allied with ease of transport, while still providing high reliability. The 409 can be used in a variety of applications, including crushing circuits, demolition and construction waste processing, and aggregates, heavy rock and topsoil handling. Power comes from a Deutz 49 kW (66 hp) diesel, and the machine features a heavy duty two bearing screenbox measuring 2,75 x 1,24 m (9 x 4 ft), integrated hydraulically cone crusher folding side conveyors and a heavy duty hopper. Mr Kulawik says that machines for wind farm work are in the 53m and above class up to the company's giant 103m working height machine. "We are just about to deliver our 30th 103m platform," he said, "they are being used in wind farm, oil and gas and building applications."
Its larger sibling, the 522T, has been designed for medium to large scale customers that require high capacity and high specification aggregate screening capabilities. It offers top and middle screen decks measuring 6.7 x 1.52 m (22 x 5 ft) and a lower deck of 6.1 x 1.5 m (20 x 5 ft), and a hopper with a cpacity of 9.2 cubic metres (12 cubic yards). Power comes from a 96 kW (129 hp) cat diesel. In transport mode the new screen measures 18.8 m (61.7 ft) in length, 3 m (9.9 ft) in width and 3.5 m (11.5 ft) in height. "The operator is always the most important so we put a lot of emphasis on the stability of boom and basket. The end user must feel safe and stable."
An example of this is demonstrated in the 120000 cycle test that was carried out on the boom of the new P 210 BK, before the machine went to market. This is said to be the equivalent of a machine in 10 years of service.
That Palfinger can supply machines for niche applications has been a help over the last few years, "Some rental companies were coming to us for the first time for a product which would differentiate them and command premium rental rates in a very competitive market."
"The rental sector is still 80% of the business and the sand making machines are developed in cooperation with the rental sector," said Mr Kulawik, "but most importantly with the operator in mind.
