Mud Recycling System for Core Drilling and CBM Drilling
GN Solids Control has provided many sets of mud recycling system, some of these solids control systems are designed and manufactured on customers’ particular demands.
Take one set of mud recycling system as an example, GN has provided a double function solids control system for core drilling and CBM (coal bed methane). Usually, there are large differences between core drilling mud system and CBM mud system due to these two drilling methods needs different amounts of drilling mud.
For core drilling, the mud system is usually has the treating capacity of 50 GPM, while for CBM drilling, the treating capacity of mud system is reach to 500 GPM.
And the separating demands of core drilling and CBM drilling is not the same, either. Generally speaking, the diameter of solids from core drilling mud system is less than 20 microns; on the other side, the solids’ diameter is usually larger than 20 microns.
This mud system including the following equipments:
1. Mud Cleaner：
GN mud cleaner is composed of dual layer shale shaker and desilter. The type is GNYZ 703E-8N, it has 8 hydro cyclones which are made of PU.
2. Mini Decanter Centrifuge:
The type is GNLW223. It is one baby decanter centrifuge that is designed especially for diamond core drilling.
3. Feed Pump:
Using Nemo pump to feed the decanter centrifuge, this pump is a positive displacement type which can avoid agitating when feeding. There are also some other centrifugal pumps that used to feed the desilter, as well as some pumps worked together with mixing hopper on mixing tank.
4. Mud Agitator:
For the mixing compartments, there are several mud agitators located on the tank, GN mud agitator is one cost-effective type for mud agitating.
5. Mud tank:
Here we use one mud tank with the length of 8m. All the above equipments can be fixed on this mud tank.
