Project Remit
Craven Fawcett recently completed a major gearbox replacement and installation maintenance contract for a leading global mineral company.
A major part of the project involved manufacturing a new gearbox for a Centaur 510 Extruder (Hybrid model), which was previously supplied as a reconditioned machine by Craven Fawcett. Subsequent heavy use and the associated wear and tear have resulted in the gearbox now requiring a major upgrade.
The machine was located directly below a filter cake press, providing a major logistical challenge for the site team. The extruder was part of a production line for China clay, which the company processes into a fine powder and is used as a raw material in the manufacture of ceramics, cosmetics, and pharmaceutical products.

The Craven Fawcett Solution
Craven Fawcett manufactured the new gearbox in its factory in Wakefield, which included producing new gears and gearbox components, the majority of which were precision engineered in-house. It was then assembled, before delivery to the customer’s premises in Europe.
The Craven Fawcett Service Team was on site for a week to provide full logistical support and undertake the installation, which included the removal of the clutch and pulley from the existing gearbox and integrating it into the new gearbox. The gearbox was then lifted into position, and the service team carried out alignment checks and full commissioning before dry testing the machine to ensure efficiency.
Gavin Richardson, Service Manager at Craven Fawcett explains: “This project involved close collaboration between our production and service teams to ensure the gearbox matched the customer’s exact requirements and could be installed quickly and efficiently. We have extensive experience in managing machine refurbishment, installation projects, maintenance, and service programmes, whether that be Craven Fawcett or other manufacturers’ equipment. The project was completed on time, and the Extruder was fully operational again within a very short time.”
