Experimental Investigation of Grinding of External Cylindrical Surfaces of Parts by Inclined Thin Abrasive Wheels

Aim. Experimental investigation of grinding of external cylindrical surfaces of parts by thin abrasive wheels that are inclined to working surface. Methods. The investigation was carried out using the methods of cutting theory, the planning of experiments, statistical processing of experimental results. Results.

Technology of Recycling, Properties and Use of Polyvinylchloride-Coated Paper Waste

The technology of recycling of polymer-coated paper waste is described. Physical and chemical properties of fibers obtained from wallpaper wastes and from their derivative compositions were investigated. A special crusher with primary and secondary grinding stages and with a section for separating paper fibers from polymer coating was designed. Industrial trials of cellulose obtained from wallpaper wastes for the asbestos cement sheets manufacturing were held. Its impact on the quality and physical and mechanical properties of sheets was shown.
