More and more North America customers are using GN Hydrovc slurry treating systems. GN hydrovac slurry systems can treat 30~50 truck loads every day (24 hours shift) when using 22 inch bowl GN centrifuge GNLW553. Centrifuge is the bottle neck in this system, 22 inch centrifuge flow rate is 15~25m3/h, and you can get 50~75m3/h capacity when use GN 30 inch centrifuge GNLW764.
Hi-cap shaker we are using opening mesh shaker screens. It helps to block those large organics before feeding to finer shaker. And feeding hopper in front of the hi-cap shaker is also fixed with metal crossing to protect hi-cap shaker.
All spare parts and wearable parts are stocking in GN Houston, TX warehouse for fast delivery. We will also provide 1 year's recommend spare parts in case you need to change it during working. GN engineers can be sent from Houston or China for after sales service and trouble shooting.
Most of our customers in USA they are using polymer in order to eliminate finer solids larger than 2~5 microns. If you are allowed to use polymer, we would suggest to use as well. If not, you can also use IPC (inclined plate clarifier) after centrifuge.
We don’t suggest to use Cuttings Dryer, as it's more expensive compared to use Hi-G shaker. GN Solids Control also manufacture cuttings dryers, to be honest there's a common issue for all cuttings dryers manufacturers which is the inside screen basket is easy to block when treat water base mud (includes hydrovac slurry). It will be more cost-effective to use cuttings dryer to treat oil based mud, separating performance is pretty good and recovered oil can be resold to make profit.
