“…Crushers of this type have a pronounced impact nature of the load applied to crushed materials, as well as the advantages of jaw and rotary crushers. In general terms, the design scheme of vibratory crushers is an oscillatory system with vibrations of 16-32 Hz communicated to the crusher jaws [17,18].…”

Obtaining a powder product from brittle materials is associated with significant difficulties: an insufficient number of production capacities as well as with their low efficiency. This indicates relevance and need for research aimed at creating new designs and technological schemes. Glass containers were selected for research from among all types of glass waste. Presented are a structural diagram and description of a horizontal pendulum impact tester, on which studies were carried out on destruction of a bottle by impact load. The impact tester gives an opportunity to determine impact energy, impact speed, acceleration, movement of the impactor. An analysis of the above figures shows that one blow is enough to destroy a bottle. Rational mode is when impact load is distributed along the length of the bottle. This mode can be implemented in a vibratory jaw crusher with an inclined crushing chamber, which includes the following main elements: a passive jaw located on shock absorbers, an active jaw pivotally mounted in the body and connected to it by means of elastic links, a two-shaft inertial vibration exciter. The presented granulometric characteristic of the crushed bottle shows a high efficiency of using a vibratory jaw crusher. The yield of the product sized less than 5.5 mm was 95%, and that sized less than 100 microns - 16%. The crusher has enough parameters to adjust particle size distribution over a wide range.
