The age of the dual power, or bi-power, mobile crushers and screens is here \u2013 allowing contractors, quarries and mines to reduce operational costs and increase equipment availability while enjoying the versatility of being able to run their crushers and screens on any remote location.<\/p>\n\n\n\n
According to Charl Marais, sales manager at Pilot Crushtec, the bi-power feature is yet another market-leading innovation by Metso, which was also a pioneer in the concept of mobile crushing and screening equipment. <\/p>\n\n\n\n
\u201cHaving listened to its market and developed mobile crushers, Metso also heard the call for its crushers to be driven by both on-board diesel generators or using a \u2018\u2019plug and play\u2019\u2019 option to connect to grid electricity,\u201d says Marais. <\/p>\n\n\n\n
\u201cAlthough bi-powered options are not new to Metso\u2019s fleet on some of their mobile units, Pilot Crushtec now encourages these features, which are available to its customers locally, and we are seeing clear signs of interest in the market.\u201d<\/p>\n\n\n\n
He highlights the significant reduction in operating costs that can be achieved by running a mobile crusher on grid electricity. <\/p>\n\n\n\n
Firstly, there are savings in diesel fuel, which is the biggest contributor to higher operating costs, as well as significant savings in diesel engine maintenance and servicing costs. Mobile units can be driven from an external power supply with the cost of electricity from a central grid generally much lower than the cost of diesel generated electricity per kW. <\/p>\n\n\n\n
\u201cSecondly, there is better availability of the mobile crusher or screen, as less time is required for scheduled servicing on hybrid mobile machines,\u201d he says. <\/p>\n\n\n\n
Other advantages of running mobile crushers and screens off electric power is the elimination of CO2 gas emissions and reduction in engine noise which is especially important when operating in urban areas. Considering the carbon footprint impact, fewer diesel engine services also equate to reduced lubricant usage and fewer consumable parts. These hybrid machines also use less hydraulic oil as drives have been replaced by electric motors.<\/p>\n\n\n\n
\u201cThe necessary servicing of the mobile crusher and screen diesel engine would typically reduce equipment availability by a further 10 %,\u201d he says. <\/p>\n\n\n\n
This raises the performance of the machine substantially, improving its cost effectiveness over the duration of a crushing contract. The additional 10% uptime that can be achieved with a hybrid machine allows the customer to service a contract within time constraints. At the same time, the dual power option equips the machines to be applied on contracts in remote areas where grid power is unavailable.<\/p>\n\n\n\n
\u201cThe versatility of the bi-power units that run either off the electrical grid or off a diesel engine allows them to be used in various contract structures,\u201d he says. \u201cSo this feature makes long term sense even when they are being purchased initially for a short term contract.\u201d<\/p>\n\n\n\n
Recent changes in South Africa\u2019s power generation landscape are also turning the spotlight on the value of dual power units. To address the shortage of electricity in the country, large power consumers like mines are looking at generating their own energy from renewable sources. As mines also usually require crushing facilities, this has started opening doors for Metso\u2019s hybrid innovation.<\/p>\n\n\n\n
\u201cWe have already engaged with mines who are considering constructing their own solar plants to generate electricity, which could then, of course, drive a bi-power mobile crusher,\u201d he says. \u201cThis option would make sense not only from a cost perspective, but would also reduce the mine\u2019s carbon footprint \u2013 an issue of growing concern in the mining sector.\u201d<\/p>\n\n\n\n
He notes that the cost effectiveness of using grid or local electricity sources \u2013 instead of diesel \u2013 improves with the size of the crushing machine, with substantial efficiency gains being made in applications where throughputs are 500 tph or more. Various items in Metso\u2019s mobile product range are already available with the dual power feature, says Marais. <\/p>\n\n\n\n
\u201cIn the mobile jaw crusher range, the LT120E, LT130E, LT106E*, LT150E*, LT160E*, LT200E* come with dual power options,\u201d he says. \u201cWhile in the mobile impactor range the <\/strong>LT1213E*, LT1213SE*, LT1315E*, LT1418E*, LT1620E*and LT7150E* come with dual power options. Dual power options are available in the following mobile cone crusher units – the LT330D, LT200HPSE* and LT330GPSE*. Lastly in the mobile screen range the ST2.4E, ST2.8E, ST3.5E,ST3.8E, ST4.8E and ST4.10E come with dual power options.\u201d<\/p>\n\n\n\n Marais concludes by point out that Pilot Crushtec is South Africa\u2019s leading supplier of mobile and semi-mobile crushing and screening equipment, and is the official Metso distributor for sub-Saharan Africa. <\/p>\n","protected":false},"excerpt":{"rendered":" The age of the dual power, or bi-power, mobile crushers and screens is here \u2013 allowing contractors, quarries and mines to reduce operational costs and increase equipment availability while enjoying the versatility of being able to run their crushers and screens on any remote location.
