Hydrovac Slurry Separation System for America Client

Recently one set of hydrovac slurry separation system are ready for shipment to America client. The customized hydrovac slurry separation system including:
1. Coarse screening module, including feeding hopper with spray nozzle for hydrovac truck loading the materials. The top of the hopper has a big opening mesh and the discharge port is controlled by valves to feed to the coarse screening shaker.


The coarse shaker with a catch tank, 2 units mud agitators are installed at each side of the mud tank for better agitating. The submersible slurry pump can transfer the fluids which is discharged from coarse solids separation shaker, and feed to the next fine mesh shale shaker.
2. Fine mesh screening module, the fine mesh shale shaker and desilter mud cleaner are installed on the shaker tank, which can be divided into 2 compartments. The solids bigger than 300 microns can be separated out by the fine mesh shaker.


3. Desilter module, The fluids will drop into the mud tank under the shale shaker, then the desilter feeding pump feed the fluids to the desilter cone of the mud cleaner. The mud agitators are installed on the shaker tank. The desilter separation cut point is 15~40 microns.


4. Big bowl decanter centrifuge module, the big bowl decanter centrifuge with chemical dosing unit are installed on the telescopic skid, the mechanical separation cut point is 2~ 5 microns, with chemical dosing system, the ultra fine solids can be also separated out. The fluids catching tank under the skid can collect the centrifuge discharged fluids and a centrifugal pump can transfer the water to other tanks. The big bowl centrifuge is a 22 inch bowl and the bowl length is 71 inch, with a positive pressurized VFD control panel.

GN Module Hydrovac Slurry Dewatering System for Overseas Client

Recently one complete set of module Hydrovac slurry dewatering system are ready for delivery.
There are totally five modules for the customized hydrovac slurry dewatering system:


Coarse screening module: GNLMP-1536 mining coarse separation screen is used to remove coarse solids from the construction slurry. The high screening efficiency and large treating capacity can ensure the further step treatment with better performance.


Fine screening module: Double deck fine screening shale shaker GNZS596K can separate fine solids from the construction slurry. The top layer screen work as coarse solids separation screen, the bottom layer screen works as fine solids separation screen, the max treating capacity is up to 140m3/h, compared with the single deck shale shaker, the double deck shale shaker can remove the fine solids better, and make the discharged solids drier.
Desanding & desiltering module: The mud cleaner is a combination of desander cone, desilter cone and bottom shale shaker. The desander cone separation cut point is 40 microns, the desilter cone separation cut point is 25 microns.


Centrifuge separation unit: The big bowl big volume decanter centrifuge GNLW553D-VFD is used to separate the ultra fine solids 5~10 microns by working with chemical doing unit, the mixed chemicals is prepared and transferred by the chemical dosing pump to static mixer, the fluids is feed by the feeding pump to the centrifuge feed tube, the chemicals adding is to increase the centrifuge separation performance and to make the discharged solids drier, which will be collected by waste collection box.
Chemical dosing unit: the 20ft containerized chemical dosing unit, including fully automatic polymer mixing, storage and injection to enhance dewatering. The container type chemical dosing unit is designed for convenient transportation, operation and for better protection.
