FIELD: process engineering.
SUBSTANCE: abrasive wheel side is recovered in separate feed of liquid binder and grinding material. Worn-out wheel hub with side disks is fitted on revolving mandrel. The said side disks served to define wheel sixes to be recovered. The said mandrel is located inside drying chamber. Liquid binder layer is applied onto the said hub and smoothed by knife. Binder amount is adjusted by varying the gal between the knife and mandrel. Grinding material is air-sprayed onto the binder. Abrasive material density is adjusted by varying mandrel r.p.m. that is selected proceeding from the necessity of preliminary drying of every layer. Loose diamond-abrasive grains are removed by turnback device.
EFFECT: expanded performances, lower costs.
