De-Oiling Centrifuge
De-oiling Centrifuges by Dr. Goessling have been well proven for years in various manufacturing processes world-wide. Especially in the production of screws, nuts or extruded parts, the centrifuges guarantee an effective, continuous manufacturing flow.
Due to their small footprint, the Centrifuges for de-oiling can be easily integrated into existing production lines. While the parts or blanks are freed from oil, emulsion, or cooling lubricant, the high-value lubricants can be reclaimed right after the de-oiling process. Not to mention, drip-free transport of the parts is accomplished.
Functionality
Our De-oiling Centrifuges (Z-series) feature perforated solid bowl drums that are pivot mounted in large rolling bearings. They are driven by a frequency controlled three-phase motor via a v-belt. Using the frequency control, the centrifuge is carefully accelerated and is gently yet quickly decelerated using DC countercurrent braking.
Every centrifuging cycle is followed by a discharge and filling process. Large buffers effectively absorb all internal vibrations of the De-oiling Centrifuge. All timed processes are controlled and monitored by an SPS-Control. The discharge and filling processes are monitored by sensors.
The centrifuged oil or other liquids are gathered and led through a pipeline to either be collected in an appropriate container or directly supplied to the according machine.

Fields of Applications
De-oiling centrifuges are used wherever metal parts must be reliably freed from adhering oils or emulsions after processing. They are particularly suitable for applications in mass production, where consistent material flow, short cycle times, and low residual oil levels are required. Thanks to powerful centrifugation, even complex-shaped workpieces are de-oiled in a process-reliable manner – ideal for use in the automotive, fastener, forming, and metal processing industries.

Advantages
De-oiling centrifuges combine high process reliability with efficient oil separation in a compact design.
Thanks to powerful centrifugal force, robust construction, and easy integration into existing production lines, they offer numerous advantages for a wide range of applications – from fast de-oiling of solid metal parts to the gentle handling of sensitive workpieces.

Continuous Operation
The parts to be cleaned are usually supplied to the centrifuge by a conveyor. They are placed directly into the collecting chute above the drum. When the correct batch size has accumulated in the collecting chute, the conveyor is stopped and a flap at the bottom of the chute is opened, charging the drum with parts. During the centrifuging process, the collecting chute is filled with the next batch.
The drum is emptied by being tipped into a discharge chute. This tipping motion ensures a complete and safe discharge of the drum. As opposed to some competitor’s systems, a jamming of parts is not possible in our centrifuges. Furthermore, our systems have no issues with leakage or liquid carryover thanks to their solid bowl design. The centrifuged fluids are collectively discharged through a drain- pipe. Overall, our centrifuges have significantly less downtime and maintenance costs. The centrifuging parameters include a wide range of adjustment. The option to reverse the spinning direction enables the best possible de-oiling, even for recessed or “cup-like” parts. By the choice, the control is either manual or automatic.
COMPACT FORM FACTOR
Coating, Drive and Design
The solid bowl drum is pivot-mounted on rolling bearings. Depending on the geometry and adhesion of the liquid on the parts, the drums are lined with perforated sheet or CONIDUR fine-hole sheet. The drive uses a v-belt and pulley system while the frequency control and counter current brake enable a gentle acceleration and deceleration.
The entire unit is mounted to a stable support frame. By changing the support frame, the charge and discharge heights can be fitted to the customers production line. The drum is filled by a collecting chute located on top of the centrifuge. The clean, centrifuged parts are discharged through another chute located near the centrifuge bottom.
Complete System Solution
We supply individually configured conveying and batching solutions to charge and discharge our centrifuges. For example, we previously designed a discharge of the parts from the drum into a Vibrating Trough Type Feeder. The feeder is equipped with a screen element that sorts out parts with production-based defects.
Stocking
In many cases, it also makes sense to include an outfeed unit or additional storage, especially if the throughput of the machines to be interlinked is different.
