Energy-Efficient Technology Supply Bulk Materials

Submission materials are the main manufacturing operation in the industry. It largely determines the quality parameters of products. Mechanization and automation of bulk material supply operation in the process eliminates human error and improves the product quality. This work was aimed at finding technical solutions that the reduction of specific energy consumption and enhance the reliability of the vibrating and pneumatic feeders. The article describes the developed the authors vibratory and pneumatic feeders.

Energy-Efficient Vibratory Feeder of Bulk Construction Materials

Any processing of bulk materials requires their moving and uniform feed (dosage). On this depends the quality and efficiency of many technological processes. For uniform and controlled supply of bulk, materials for transporting or processing machines use feeders. Among feeders in recent years, an increasing distribution received disk vibrating feeders, which are characterized by small size, without moving parts, prostate, reliability, accuracy and smooth control supply. Disk vibrating feeder has a horizontal spreading disk, which is located coaxially and with a gap below the outlet of the hopper. Spreading disk is connected with vibratory drive. This research was aimed at finding technical solutions ensuring the reduction of specific energy consumption of disk vibrating feeder. The study showed, that if the spreading disc perform with a central hole, which is closed by an elastic membrane, then this can significantly reduce the specific energy consumption per unit of production.

Quality control of fireproof coatings for reinforced concrete structures

The article analyzes methods of quality inspection of fireproof coatings (work flow, measuring, laboratory, etc.). In modern construction there is a problem of lack of distinct monitoring for the fire protection testing. There is a description of this testing for reinforced concrete structures. The article shows the results of calculation quality control of hatches as an example of fireproof coating for reinforced concrete structures.
