In some mining projects, before the exploitation, the contractor would like to do some research on the geological condition. The most popular method is to use the core drilling machine to get some sample of the stratum. By analyzing the stratum sample, the mining operator would get some basic information like the mineral reserves and what kind of the mineral it is.
When getting the sample of the stratum, the contractors always apply to use the core drilling machine to get a series column shape stratum. The drilling bit is a type of pipe, not like the drilling project for oil and gas, the core drilling not need too much drilling fluids to cool down the drill pit and take the cuttings out from the drilling whole. However, in order to make sure the better performance of the drilling process, the drilling contractor always will get a solids removal unit to separate the drilling cuttings from the drilling fluids.
Now the solids removal package unit specially for core drilling designed and manufactured by GN Solids Control has already been applied on site and the performance was proved good.
In GN’s solids removal package unit, the equipment involved is as below:
Shale shaker model of GNZS752 with 2 panel screens, which is used as the first stage solids removing unit to separate out the larger size solids in the drilling mud.
High speed decanter centrifuge GNLW223 which is also the key equipment in this solids removal unit. It could run at a typical speed of 3800 RMP that ensure a good performance for dewatering. The semi-dry solids discharged out from the centrifuge unit could be transported easily.
Considering the requirement of the small footprint, this solids removing unit is designed structure compact and the mud tank only has 2 compartments separately to be used for sand settling and mud mixing. The centrifuge pump used in this system could both transfer the mud to centrifuge and mud mixing. This dual function centrifugal pump saves great power cost and reduces the system size.
For the power supply, GN could also provide a diesel generator as an option.
