Why Companies are Turning to Mobile Crushing and Screening Plant

Unlike a great deal of construction equipment, the category of crushing and screening plant has seen comparatively little innovation over the years. The jaw crusher for example, has remained largely unchanged in roughly 60 years. As in other sectors of construction and mining, the major improvements came with the implementation of hydraulics, but by and large these simply improved the speed and reliability of the equipment.
The nature of the industry requires reliable machines that can deliver efficiency over long periods, and the machines must be able to stand up to demanding conditions and heavy usage. Whilst many mining companies have worked the same sites for years, the changing nature of the energy industry and the growth of new economies has seen new mining concerns spring up across the globe. Big industry and global manufacturers are turning their attention towards South East Asia, Africa and Latin America, where there are huge gains to be made by those willing to take the plunge.
Naturally, companies are looking for machines that will stand the test of time, but they also require plant that can adapt and remain useful long after their initial application is over. Once upon a time, static crushing and screening equipment was always the way to go. Companies would make big investments on big mines, and sit massive crushing and screening plant on top of their investment to harvest the benefits for years to come.
Now, more and more manufacturers are creating mobile plant that can suit a variety of applications suited to the needs of customers. The initial costs are lower, and the profit-affecting transport of material from static plant is no longer a problem. If these were the only benefits, companies would not be as inclined to switch over, after all, static equipment pays for itself after a long enough period of mining. So what are the other reasons for going mobile?
From the manufacturer’s point of view, it makes good business sense to produce and sell equipment that can be used in a variety of applications, because it makes the machines appeal to a broader range of customers. Whilst static crushing and screening plant is sat atop a mine, mobile versions can be employed in road and bridge construction, urban construction, metallurgy as well as energy industry roles. They are capable of doing more, for more people, in more situations.
From the perspective of the end user, mobile plant can be even more useful than static equipment in certain mining roles. Mobile equipment is more suitable for surface based, opencast coal mining for example, where multiple types of crusher can be used to deal with the several layers of material, from the rock layers, gravel and cement, as well as Jurassic strata, middle sandstone, and fine sandstone. Adaptability and multiple layouts are essential to efficiency for this kind of operation, something that mobile plant offers in abundance.
Whilst static plant is designed purely for a single purpose, mobile versions, whilst being cheaper, can also be fitted for specific tasks and improved with safety features.for each application. For example, cone crushers have been used for decades, but like jaw crushers their design has been largely unchanged. Reliability, a concern shared by all construction and mining companies, was the major issue. Foreign objects, especially steel, can prove fatal to cone crushers, in most cases rending them useless. The introduction of hydraulics led to important improvements in reliability, in the form of mechanisms that protected the crushers from foreign objects causing costly damage.
Screening has come a long way from prospectors sifting pans of dirt for gold in the Old West, and mobile screening plant features the latest innovations in circle-throwing, high frequency vibrating and gyratory mechanical screening that you would find in static equipment, all integrated into portable machines that can be customised to suit all manner of applications.
This, along with obstacle-removing features and multiple configurations to suit every purpose, make mobile crushing and screening plant more adaptable, reliable and cost-effective than their static counterparts. In a world where larger investments are not as easy to make as they used to be, getting the most out of heavy equipment has become a chief concern, and more and more companies are turning to mobile equipment that can get the job done faster, better and cheaper than ever before.
