Main directions of improvement of vibrating jaw crushers

Article preview

Crushing and degradation are the greatly using process for industry. It are take up almost 20 % energy output in the country. Share capital, operation and power of costs for crushing and degradation for factories, which are use this process, equal to more 50 % their economics balance. Because cost reduction on crushing and degradation is actual tasks. Main structural layouts of jaw crushers and their tendencies in the contribution.

Technological and dynamic studies of new designs of vibrating crushers

Article preview

The principal and constructive features of vibroinertial crushers are considered, the fields of their application, new approaches to their calculation and design are indicated. The considered equipment is intended both for selective opening of rocks and for disintegration of any hard, brittle materials. Selective opening of crystallites with minimum overgrinding is achieved by applying to the bulk layer of material of strictly dosed compressive forces of inertial nature and impulse vibration shear loads, causing a gradual softening of interfacial bonds. The main compressive and shear forces in these machines are created by centrifugal forces of inertia, and the material, being destroyed in the layer, is subjected to intensive vibration action.

Prospects for improving vibrating jaw crushers

Article preview

The current problems associated with the recycling of waste reinforced concrete, and ways to solve them are considered. The analysis of designs of existing crushers is presented. Particular importance is given to the new vibrating jaw crusher with vertical and inclined execution of the crushing chamber. Such advantages of the crusher as dynamic equilibrium, the ability to pass non-crushing bodies through the crushing chamber, the ability to destroy materials superior in strength to the material of the crusher's armor are considered. The growth of productivity in 2 times in comparison with the vertical execution is revealed at the inclined execution of a crushing chamber, what substantiates the necessity of more profound research of the vibrating crusher of the given type. The main stages of the research of new vibrating equipment, which will provide the necessary information for the development of vibratory jaw crushers of a new technical level and different sizes for use in cyclic-flow technologies, are defined.
