Centrifuge for drilling mud treatment, because the separation target is not very clear and not specified, the target is to cut mud weight or recover barite, and it is easy design compared with other industry centrifuges. 14in or 18in bowl centrifuge is popular for mud treatment, Swaco 518HV, Derrick 1000, Brandt 3400, they are all 14in centrifuges.
But mud has bigger density and will wear
the screw impeller inside centrifuge, so the centrifuge design need to pay
attention to 3 points
1- need a larger torque (with bigger motor
power)
2- the impeller needs to be designed
wear-resistance.
3- the centrifuge should be shorter, bowl length/diameter ratio should be about 2.5~3, that is okay.
With many years experiences in the design and manufacturing of high speed centrifuges, KES Separation has mainly 2 part to support the demanding market. Part 1, we have standard centrifuges with standard parameters to apply in solids control mud treatment. Part 2, we can offer customization service to fit better for customers with demanding requirement- this normally means for other field application, eg. Pharmaceutical material separation, municipal sewage separation, mining slurry separation etc.
Recently, we are almost finish the production of blue-sky centrifuges, it is 1set 14in centrifuges will be delivered to land rig site. The 14in centrifuge with a bowl length/diameter ratio to be 3, replacement to Swaco 518HV or Derrick 1000 centrifuges. The centrifuge spindle impeller was protected by carbide alloy tiles for better anti-wearing performance, but there is also risk the tiles will be damaged when some big particles enter the centrifuge in high-speed operation and damage the balance status. In order to solve the problem, we can add one speed accelerator in the position of feeding port, that is, the materials rotation speed firstly accelerated, and then enter the chamber of separation. In this case, the wearing to impeller can be minimized because the impeller rotation speed and the materials rotation speed are almost same. To avoid the alloy tiles problem, we can use Duplex SS2205 stainless steel and without alloy tiles protection and to eliminate the risk of damaged tiles to damage the balance.
Good design centrifuges is not easy to design and fabrication, our engineer with over 20years experience can achieve the challenging customization demand from various field. Good design centrifuge can work continuously for at least 20 years, and help to reduce operation cost and working risks. Welcome to contact us if you need some customization service in centrifuges and other solids control equipment.
