Mining means extracting mineral resources from the upper earth’s crust.
In the course of this extraction and the depths required to mine the raw materials, water is inevitably encountered underground. Depending on the occurrence of water, entire galleries can be flooded and there is a considerable danger for the miners.
Therefore, attempts are often made to use this occurring water as service water or as stock for fire protection.
In a large Russian mining company in Kusbass, there have long been problems with the filtration of the water for use as a fire barrier. The automatic filters previously used could not reliably filter out the enormous amount of dirt particles, such as sand, small stones and mud, and regularly became clogged. This made it necessary to clean these filters manually, which took time and caused additional costs.
By installing a separator from DANGO & DIENENTHAL upstream of the automatic filters, it was possible to significantly reduce the rinsing intervals of the automatic filters and also to reduce the manual cleaning cycles that had been necessary up to this point to a minimum. The separator is particularly characterized by the separation of heavy particles with a density greater than 1.3 kg/dm³. The existing sand and stone particles can thus be separated in the first step via the separator. The separator can be installed both stationary and as part of an energy aggregate without a special room.
These separators are now used in many mining operations for the filtration of process water. The pre-filtration protects automatic filters or spray nozzles, for example.
Experience has shown that the low cost of purchasing and installing the separators pays for itself after only a few months, due to the saved maintenance time on the existing technical equipment in the mine, the longer service life of the filter elements of the downstream automatic filter and the reduction in incidents. This offers the companies a high economic benefit.
