Mobility is the future for recyclingPublished 19/4, 2016 at 10:39
Mobile recycling equipment is an efficient choice for demolition contractors when the location of the waste for recycling changes regularly. There are many manufactures of mobile equipment that improve on-site recycling performance. Mikael Karlsson reviews some of the latest equipment.
Sandvik Construction is launching the secondary cone crusher QS331 designed to accept large feed sizes and achieve high production capacities for applications such as Type1, crusher run or in primary gravel crushing.
The S type gyratory cone crusher has proven itself in stationary applications for over 30 years, becoming one of the most reliable, versatile and productive cone crushers on the market. This proven technology has now been incorporated into a self-contained, diesel driven track-mounted plant, providing customers with superior performance and high product quality in a mobile version.
Many customer benefits are delivered, as the S type gyratory cone is able to accept a feed size up to 90% larger than current standard cones. This enables maximum productivity to be enjoyed from the primary crusher, or even facilitates the use of the S cone as a primary crusher on gravel applications.
The CS430 cone crusher sets the 36t Mobile QS331 apart. It has a choice of three concaves, and four bush settings to control the closed side settings and material gradation.
Due to the large feed acceptance, production may be optimised by opening the CSS, thereby also reducing fuel consumption and wear. It is the ultimate Type 1 provider, whilst being equally suited for crusher run 6F5 material or railway ballast or drainage stone.
Sandvik is also expanding its range of scalpers with the launch of the new QE241 heavy-duty unit. Compact in design and easy to transport, it is possible to benefit from the same user-friendly features from the Premium range of scalpers, yet in a smaller version.
Sandvik has developed the QE241 based on customer feedback. Although primarily targeting the European market, it will be an ideal solution for smaller end users where performance, versatility, transportation and setup times are most important.
The QE241 also benefits from Sandvik’s history of mobile scalper development as well as sharing common characteristics from its larger siblings, including a two way split configuration option and sequential start-up.
Capable of scalping before or after a small crusher, the QE241 features a heavy-duty variable speed belt feeder and a double deck screenbox. This, combined with the banana-type bottom deck arrangement, will provide a highly effective and efficient screening solution.
The 1.2m wide conveyor can handle oversize material and two hydraulically folding side conveyors handle the fines and midsize products. With a wide choice of screen media available, the QE241 offers customers a highly versatile unit, which can be configured to suit specific requirements.
Its chassis has been designed to be compatible for two-way or three-way split versions, a unique feature in this product category. The safety and comfort of use is of paramount importance for our operators. A key benefit is the easy to use control system and user interface with sequential start, a common feature across the 1 Series screens and scalpers. The model also comes with two-speed tracking.
The 17.5t model comes with hydraulically folding tail and side conveyors, together with a rigid one-piece hopper for quick set-up.
The Canadian mobile recycling equipment manufacturer McCloskey International is introducing new features and benefits to the I Series impact crusher line: the I44 and I54 crushers. They are particularly suited for aggregate and concrete recycling applications and have been enhanced with a number of production boosting features.
These include changes to the 1.05m diameter x 1.1m wide impactor side wall angles to allow better material flow and a re-designed under pan that delivers more throw and enhanced material movement. There is also a new feed boot on the main conveyor to accommodate more material flow from the under pan.
One of the key features is a radial return conveyor that allows recirculated oversize to either go back to the hopper, be stockpiled or fed to another machine.
The new I44R also features a TEDD panel that is easier to understand. For quarries with multiple equipment operators, training is reduced as the panel is easy to read, and displays more functions in an intuitive manner.
The I44R has excellent access for maintenance with its open chassis design. With additional options such as a water pump and dust suppression system, or refuelling pump, as well as its high standard safety features, the I44R is high performance, portable and productive.
Easy to move from site to site, the I44R has transport dimensions of 3.41m high and 15.36m long, including optional magnet and hopper extensions. With the advantage of McCloskey’s integrated hydraulic folding hopper and conveyors, it can be on-site and operational in a matter of minutes.
McCloskey is also presenting the new R155 dual power mobile screener, aiming to provide maximum flexibility and significant savings on energy costs for customers.
The R155 dual power can switch between the two sources of energy. Connected to external electricity supply sources, the Dual Power R155 is adaptable, and able to work in a variety of sites around the world.
Metso is on track to present the mobile M&J PreShred 4000 in two versions as a crawler and a trailer. Both models are able to process all kinds of waste in almost any location. With easy operation and easy service the shredder meets the requirements in the recovery and recycling business.
“What makes the M&J PreShred 4000 Mobile so special is that it introduces a new generation of equipment with a hydraulic load sensor for optimum clogging management and with the ability to restart instantaneously at full speed,” said Metso Denmark research and development manager Johannes Kjærsgaard. ”Moreover, if an un-crushable item passes through, only one rotor will be affected by the brief overload, the other will continue to function as normal. The Caterpillar C15 engine delivers a significant 20% reduction in consumption compared to previous generations.”
Doppstadt and Siltbuster
The Austrian manufacturer Doppstadt and its partner Siltbuster are set to launch the Gritbuster. This is a new mobile washing and wet waste recycling system, that puts an end to the time-consuming and expensive treatment of waste materials such as gully waste, road sweepings, sand or gravel. It is also suitable for sorting and separating coarse and fine materials from construction and demolition.
The Gritbuster series includes two models with different feeding methods and capacities. The Gritbuster WT-100 can achieve up to 15t/h. The Gritbuster WT-250 processes pre-dewatered or stored wastes up to 25t/h.
Both machines work on the same principle. Clean water is used to wash and sort the waste streams. The cleaner the washing water, the higher the recycling product quality. Since water is not available in unlimited quantity, the Gritbuster recycles its separating medium.
Gritbuster uses water to separate undesirable materials in the input material and recovers it by its own closed-loop water treatment circuit. In this way, the Gritbuster works independently of settlement ponds.
The machines are suitable for stationary and mobile applications. The Gritbuster achieves outstanding separating performance, while using water as a separating medium in an environmentally friendly, resource-saving way.
The Austrian manufacturer of mobile crushing and screening machines, dsb innocrush, will launch the revised innocrush 35 at Bauma.
The engine package for hydraulically opening and the innodrive drive concept without clutch is standard in all dsb machines. The main conveyor belt of the innocrush 35 will now be longer and steeper, which has a positive effect on discharge height.
