Double deck shale shaker and High G shale shaker is widely used for oil and gas drilling rigs site.They can be used for both mud solids control or drilling cuttings waste management.
They are both linear motion shale shaker. Many customer do not know the difference of Double deck shale shaker and High G shale shaker. Below is the explanation from world top solids control and waste management equipment manufacturer – GN Solids Control. Let GN tell you the difference of the 2 types of shale shaker and choose the suitable model for your drilling rig.
Double deck shale shaker, linear motion: GNZS703D
GNZS703D is the typical double deck shale shaker. It utilized 2 each shaker screen for top deck and 3 each shaker screens for bottom deck.
Advantages of GNZS703D double deck shale shaker
1). For the same API size and the same area bottom shaker screen. double deck shale shaker can treat a bigger capacity. The wide-meshed shaker screen on top deck can separate most big size solids before the mud enter into the bottom deck. It greatly reduce the load of bottom shaker screen.
2). For the same API size and the same screen area shaker screen. double deck shale shaker can separate the drilling mud or drilling cuttings more dryer. As there are 2 times shale shaker separation.
Disadvantage of double deck shale shaker
The double deck shale shaker have advantages of bigger advantage and dryer separation result, but it has some difficult to change shaker screen. And the cost of replacement shaker screen also higher, as there are 5 each screen for a shale shaker.
High G shale shaker, linear motion: GNZS594
GNZS594 is a high G shale shaker model, with linear motion. It uses 4 panel shaker screen. And the shaker screen interchangeable with Swaco Mongoose shale shaker, composite material. It is single deck, relative easy to change shaker screen compared with double deck shale shaker.
So the user can choose shaker type per your drilling rig conditions and per your applications (for solids control or for waste management). If you have a higher solids content, or want bigger capacity, and take more time for screen changing is not problem, you can choose double deck shale shaker. If you prefer fast screen changing, high G shale shaker single deck is better.
