High Speed Mixers Home › Aftermarket › Rebuilds › High Speed Mixers Even when a rebuild is required, it is likely that the essential core components of the mixer remain sound – the mixing blade, frame and bowl. A rebuild would therefore involve the following: Renewing all bearings and bearing housings. Upgrading motor and controls to the latest specification Renewing inlet valves Replacing painted doors with stainless steel doors Repainting Revitalise by rebuilding Machines nearing the end of their useful life can often be revitalised by rebuilding either on-site, or in a Baker Perkins factory. Rebuilds use proven Baker Perkins Original Equipment Manufacturer (OEM) parts so high quality and long life are assured.
