Fluids Filtration Systems in Mining Machines

Mining machinery is very expensive equipment.  Its operation requires specific technical knowledge.  Its effectiveness directly depends on maintenance, service and qualification of personnel.  However the principal role is the quality of filtration of  working fluid, which is subject to contamination due to intensive use.

An appropriate level of purity of  working fluid:

  • increase service life of drive units and improve machine availability;
  • increase drive efficiency, thus raising equipment productivity;
  • reduce fuel consumption (by 7-10%) and hydraulic oil consumption (by 15-25%).

Each mining machine, coming out of production, has a standard level of oil purity.   In theory, this purity level of  working fluid  should stay throughout the service life of mining equipment.  In practice, actual contamination of hydraulic oil significantly exceeds the norm, and regular filters are not coping with it.  Under such conditions, the main hydraulic equipment of, let’s say, excavators are able to work only 30-70% of their nominal life.

Thus, the main reason for reducing mining machinery operation is in unsatisfactory condition of their working fluids.  In order to prevent accidents and forced outages – working fluids should be controlled using special equipment for sampling and analysis.

The main task of monitoring working fluids – is identifying the load on  filters and oil pre-treatment, as well as oil regeneration and reuse.  In many cases, regular sampling shows the stability of the chemical composition of oil in operation. The quality of oil is also monitored on a seasonal basis.

When  contamination control results exceed the set values oil and fuel pre-treatment is carried out  When oil and fuels are supplied having 14 to 16 cleanliness class.  Practically, this means that 18 to 75 grams of contamination must be removed from each filling container before oil fill.

It is suitable to be reused after a deep oil filtration (removal of finely dispersed water and particles with a size of less than 3 microns).

Filtration of mining machinery working fluids to reach the required cleanliness class can be achieved by:

  • improved  existing filtration systems;
  • additional filtering systems;
  • special devices, reducing fluid contamination during transportation and fills;
  • regeneration plants.

Of course, the best effect is achieved by using a variety of measures.  But  it is necessary to make economic calculations, since the introduction of any new measure aimed at maintaining the operating condition of oil entails certain financial expenses.

But the benefit of regeneration systems is beyond doubt.  By purchasing mobile oil filtration plants, you kill two birds with one stone.  First, you get an opportunity to use waste materials again for their intended purpose.  Regenerated oil is comparable to new oil in terms of quality and performance characteristics.  It eliminates the need for purchasing fresh oil for replacement.  It saves expenses.  Secondly, environmental aspect is very important.  Multiple recoveries of working fluid properties postpone the problem of disposal for a long time.

GlobeCore manufactures equipment that  solves absolutely any problem in the field of mining equipment operating fluids filtration.  It is possible to perform oil pre-processing before filling in the system, and regeneration of used oil.  GlobeCore processes restore purity class of working fluids to quality values.

With GlobeCore mining machinery live long and preserve  the environment!
