KBK Engineering’s Maintenance and Service
for Decanter Centrifuges
We offer technical strengths backed by manufacturer and user certification and a record of performance in fabrication, maintenance and service for decanter centrifuges with 40-plus years of experience since before our spin off from Kurashiki Boring Kiko Co., Ltd., which is our partner company. KBK Engineering Co., Ltd. is a company that specializes in maintenance and service for rotating machines; specifically, decanter centrifuges. We offer integrated service from advice on diagnosis, condition confirmation and stable production as well as appropriate inspections, hard-facing, thermal spray and plating repairs necessary for maintenance and service, machining and dynamic balance corrections, test runs, and diagnosis. We offer a record of performance for a variety of repairs, including repairs for bowls, screw conveyors and gearboxes, which are main components, as well as bearings and fitting parts, repairs for lip marks of oil seals, welding and hard-facing of screws, fabrication of gears of differential gear units, and hard-facing repairs for spigot joints. We not only conduct simple repairs but also repairs best suited to parts that are needed, for example, high-precision dynamic balance required for stable operation of the entire centrifuge, and extending machine life by fabrication of new parts that can no longer be repaired. After repairs, life-span is extended due to reductions in noise and vibration as a result of smooth rotation, and productivity is also improved due to reductions in moisture content in processed materials and quality stabilization. Indicators for determining the timing of maintenance and service include rising temperatures of bearings, leakage of grease or processed materials, abnormal sounds and vibrations, as well as other process abnormalities, such as increasing liquid side concentration of processed materials and changes in the properties of solid matter.
- Replacement of strips, inner surface turning, hard-facing repairs for spigot joints, dynamic balance corrections
- Screw conveyor
- Hard-facing of worn blades, rewinding of blades, dynamic balance corrections
- Fabrication of gears, hard-facing repairs for gears, repairs for fitting parts
- Welding repairs for cracks, repairs for chutes, modifications
As shown by the above wide-ranging examples of maintenance and service requested, we are a maintenance and service company specializing in decanter centrifuges that can handle repairs in-house or in conjunction with our partner company.
