ALL modules in container. The special part of this system is all the equipment been placed into container, for easy & flexible operation / transportation. It also contains Feeding Pump; Pre-Mixing and Heating Tank; Shale Shaker Treating Unit;2 Phase Centrifuge Treating Unit; 3 Phase Disc-Centrifuge Treating Unit, and dosing container for checmicals.The key elements are vacuum pump, shale shaker, decanter centrifuge, disc separator.
GN sludge vacuum pump is a 100 percentage pneumatic driving pump that can be used to transfer various materials ranging from liquid, slurry, wet sludge and even solid power and gravels. In many mining site, the miner is using high pressure water to flushing the ore, and then they need to dewater the ore slurry. All the ore slurry will be collected firstly in a pit waiting for transferring to the dewatering machine. GN sludge vacuum pump is an ideal equipment to take the slurry from pit due the small footprint, compact structure and moveable design. In the meanwhile, equipped with big power air compressor, the sludge vacuum pump can suck the sludge and discharge the sludge from and to a long distance, which greatly saves the manpower and increases the working efficiency.A submersible pump suck the diluted oil sludge and feed into GN shale shaker treating unit. Double deck shaker is widely seen and anti-sparing cover as well as flushing nozzles are fixed on the shaker to keep the shaker screen from blocking.
GN 2 phase decanter centrifuge removes most of the those larger solids from the slurry discharged by shale shaker. After treated by GN 2 phase centrifuge, solids with oil is around 1%-3%. TDU might be used to further treat the solids discharged from shale shaker and decanter centrifuge.GN 3 phase disc stack separator is a high-speed, stable, sealed, efficient, and automatic slag discharge 3 phase separation equipment. It is widely used for liquid, liquid, solid 3-phase separation or liquid-liquid separation. The 2-phase solid-liquid separation disc separator has only one liquid discharge port and one slag discharge port, while the 3-phase disc separator has two liquid discharge ports and one slag discharge port, which can separate two liquids with different specific gravity at the same time. It can also discharge solid phase materials. Compared with the 3 phase decanter centrifuge, the 3 phase disc separator has larger rotation speed and G force. The 3 phase decanter centrifuge usually has a separation factor of about 3000G, while the 3 phase disc stack separator G force is up to 12000G. Therefore, the 3 phase disc separator can more thoroughly separate liquids with different specific gravity and the liquid phase discharged is more clarified. However, compared to 3 phase decanter centrifuges, 3 phase disc separator is more used to separate materials containing fine particles, with less solids content. So before entering the 3 phase disc separator, the material can separated by the decanter centrifuge for pre-stage separation to reduce the solids content and remove big particles.
Solids liquid separation decanter centrifuge can be used in various industrial processes that need to separate the solids and liquid. Recently, GN finished the fabrication of one batch of small decanter centrifuge for a client from South America.
Solids liquid separation small decanter centrifuge is also called mini decanter centrifuge that can be used in many fields. Below listed are several applications of the small decanter centrifuge.1. Small Capacity Drilling Mud Recycling – the typical application of small decanter centrifuge in mud recycling is the diamond core drilling solids removal unit. Normally, diamond core drilling rig is small; therefore the mud flow is small. GN small decanter centrifuge is an ideal solution for this application.2. Demo Unit – clients who do solids liquid separation job always need decanter centrifuge. For various mixtures of solids and liquid, some clients need to verify if the decanter centrifuge would be applicable for their project. A small decanter centrifuge would be the choice with low cost, in the meantime, a practical solution.Features of Solids Liquid Separation Small Decanter Centrifuge
1. Multiple designs available – GN small decanter centrifuge is with bowl diameter 9 inch, according to requirements of clients, GN can provide the decanter centrifuge with L/D ratio of 3 or 4. Generally, a longer L/D ratio will bring a better separation performance as the slurry will stay inside the bowl for longer time.2. Fixed Speed and VFD Control available – GN fixed speed small decanter centrifuge is suitable for working condition requests only one speed, the control panel is easy to operate, it is a cost saving option. VFD control model decanter centrifuge can be used in various applications by changing the bowl speed and differential speed.3. Standard Wearing Protection – to ensure the service life of the decanter centrifuge, GN manufactures the decanter centrifuge with protection of tungsten material at the screw propeller, slurry distribution port and solids discharge port. The tungsten material can be plate or spraying welding.
GN provide solids liquid separation decanter centrifuge in different sizes for various purposes, such as dewatering, clarifying and separating. For more information of GN decanter centrifuge, please feel free to contact with GN Separation & Conveying.
