200gpm mud recycling system for HDD machine

BY gnadmin 29 October 2019 Uncategorized

As one of the most professional HDD mud recycling system in China, we can design and produce mud cleaning & mixing unit with different treating capacity as 200gpm, 350gpm, 400 gpm, 500gpm, 600gpm, 800gpm, 1000gpm, 1500gpm, also we can provide customized design mud recycling system as per client’s requirement. Below is the 200gpm mud system photo we shipped recently to our HDD industry client.

The working process is as below:
The submersible slurry pump pick up the used drilling fluids from the waste pit to desilter with double deck shale shaker: the first phase is bottom deck shale shaker to separate coarse solids so that the drilling fluids can be feed to desilter cone properly. The centrifugal pump feed the clean drilling fluids to desilter cone to separate fine solids with cut point 2~5 microns, the clean drilling fluids drop down into the mud tank, the user can add powder chemicals into the venturi hopper, the mixing pump provide proper pressure to help mixing evenly. The clean fluids are ready for recycling in the mixing compartment. The mud agitator and mud gun are agitating the fluids to prevent the solids suspension in the tank bottom.

The technical configuration is as below:
1) 1 unit of GNZY753F-Y4N mud cleaner ( double deck shale shaker + desilter cone), all the shaker screen installed on the mud cleaner is composite material shaker screen, the desilter cone is 100% polyurethane material with better wear resistance material.
2) 1 unit of feeding pump
3) 1 unit of mixing pump
4) 1 unit of mixing hopper
5) 1 unit of 2 inch mud gun
6) 1 set of mud tank with tank accessories, with electrical control system and lightings
Another unit of 200gpm mud system under production for the same client, last year they purchased 3 sets of 600gpm mud system.

The shale shaker is dual motion shale shaker, one is linear motion shale shaker with max 140m3/h capacity, the other one is progressive elliptical motion with max 100m3/h, there is control on the starter to change the vibration motion. The starter with Cast aluminum Control Cabinet, the electrical components are from Siemens/ Schneider/ABB brand for convenient outsourcing.
2) Triple shaker skid with 2 ways slide gate as drain port, during shipment, the 3 shakers, possem belly and skid will be disassembly to suit for the container loading.
3) Possem belly with slide gate for convenient operation
The mud cleaner with the same bottom shale shaker and same dimension shaker screens, the top hydrocyclones frame installed with 3 nos of 12 inch desander cone, 20 nos of 4 inch desilter cone with total treating capacity of drilling fluids over 1500gpm. The 20 nos of 4 inch desilter cone in 10 sets. The cone material is 100% polyurethane for longer working life.
This is special designed for our customer’s requirement, we have standard triple shale shaker and mud cleaner as GNZS594F-SHBF and GNZJ594F-3S16N if no special requirement.

Composite material shaker screens ready for shipment

BY gnadmin 29 September 2019 Uncategorized

Recently we have one batch of composite material frame shaker screens ready for shipment for a international drilling companies. We packed 18pcs screens at each plywood pallet, each piece screens packed by GN standard design paper box, we can also provide neutral paper box as per client’s requirement.

GN shaker screens are produced as API RP13C standard and have test report from API authorized agent in America. We can produce shaker screens from API 20 to API 325, the mesh size over API 60 all adopted 3 layers stainless steel wire mesh for better strength. The composite material frame lasts longer working life than steel frame screens, and larger effective screen area for better separation performance.

Shale shaker is the first phased cleaning equipment at solids control system, shaker screens are consumption parts of shale shaker, the user always make proper stocks for the shaker screens for convenient operation, the composite material frame screens can be storaged up to 5 years without getting rust. Based on different drilling fluids, the shaker screens working life will be different. The composite material shaker screens are repairable with plastic plug. The 3 layers 4-sides pretensioned wire mesh before heat pressing will provide enough strength. We can make customized color for the composite material frame as per client’s requirement. We adopted wedge as shaker screen locking system, the user can replace the shaker screens easily and fastly, the user can use the ratchet wrench to lock and release the wedge and take the shaker screens easily. The shaker deck angle can be adjusted by both sides simultaneously from -1ºto +5º.
When install the desander and desilter frame on top of shale shaker, the 3 in 1 mud cleaner as the second phase cleaning and the third phase cleaning equipment. The desander cone and desilter cone are 100% PU wear-resistant material.

Offshore mud tank system is ready for shipment

The screen lock method is by wedges with ratchet wrench for convenient locking the screens.

2) One unit of mud cleaner( desander cone, desilter cone and underflow shale shaker combination) with 2 centrifugal pump as feeding pump, the centrifugal pump is interchangeable with famous brand centrifugal pump, the hydrocyclones are 100% PU material for longer working life, if the mud temperature is higher than 80 degree, we will use metal cover outside the PU cone to prevent is from deformation.
3) One unit of decanter centrifuge with submersible slurry pump as feeding pump
4) Compact design mud tank with all the electric cables outside the mud tank for convenience replacement and check. The discharged solids/ cuttings are collected by a slant box and drop down to the screw conveyor to transfer the cuttings to the drilling waste management system.The user do not have to clean the floor and do not need extra skip to collect the waste cuttings. The handrail, walkway and stairs are installed with the mud tank.
5) The mixing hopper, mixing pump are installed on the mud mixing tank if the client need to prepare for new drilling fluids with the recovery drilling fluids.
