Five hundred tonnes per hour feed capacity, up to seven final fractions(five that comply with strict standards for asphalt and concrete production) – and all this is possible using mobile plants? Using the plant combination at Kelly?s of Fantane in Ireland, Kleemann has demonstrated what can be achieved using mobile plants.
Mobile crusher and screen plants are advancing more into output ranges that only a few years ago were possible with stationary plants. Examples like Kelly?s are guiding the way for the future.
What are ?interlinked mobile plants?? They are crusher and screen plants co-ordinated to work together in terms of output and operation. Two, three or more plants can be combined for use in both natural stone quarrying and recycling. The potential output of such plant combinations ranges from 100tph up to 500tph.
WHY ARE INTERLINKED PLANTS BECOMING MORE POPULAR?
Experience shows that the licensing procedure for mobile plants is shorter and less complex than for stationary plants. The use of the plants in spacious areas and in technical applications reduces the investment risk. They can also be resold, the advantage being that manufacturers can offer plants for large tonnage in various crushing and screening stages.
POTENTIAL AREAS OF APPLICATION
Due to the development of interlinked plants in recent years, the mobile plant is becoming a real alternative to the stationary version in numerous projects. For this reason, operators consider whether an original stationary concept with mobile units is more economical. It is beneficial to operators of stationary plants who are making new investments in machinery. It is also feasible for large infrastructure projects that are limited in terms of time or scope and located in sparsely populated areas. A combination of mobile plants could also be used for newly opened quarries and recycling projects.
REQUIREMENTS AND EXPECTATIONS
Of course, requirements are high. There must be a guarantee that top quality end products, with regard to cubicity and output, can be manufactured. The process must also be commercially reliable.
There must be cost advantages, which are noticed less in the procurement stage and more during the operation of the plant. In large quarries, it is often possible to load the crusher directly at the wall without the full use of heavy duty vehicles. This leads to considerable savings not only in vehicles and machines, but also personnel.
At Kelly?s of Fantane, operations manager Martin Flynn explained that all machines are linked through a computer-supported system. ?The bottom line is we produce 500 tonnes per hour with one man,? he said, adding that since Kelly?s have used Kleemann plants, ?we now produce more in a single shift compared to the previous two shift operation?.
Kleemann not only offers interlinked plants but also the relevant process know-how. It assesses and designs the required technical process safely and reliably, and ensures implementation by providing customer support in the transition from stationary to mobile plants.
The decisive factor is the Kleemann plants themselves, which offer relevant operations in the plant design and robust, sophisticated, high performance machine technology. Jaw, impact or cone crushers have split feeding for optimal loading, large primary screens for optimal final fraction quality, stable control voltage and separate monitoring of machines. They also have ideal access, easy maintenance and diesel-electric drives with the option of external power supply that makes feed capacities of unto 700tph possible. All these characteristics are ideal for interlinked plant concepts. Optimally coordinated mobile screening units also provide reliable end classification.
