Abstract

The objects of the study were TiN-Mo cermet, as the final product of the reaction. Thermogravimetric study of cermets of the TiN + Mo and 2TiN + Mo systems revealed two exothermic peaks at temperatures of 560 °C and 700 °C, which may be related to the oxidation of dissolved and of titanium. The increase in mass after a complete heating-cooling cycle at the maximum temperature of 950 °C was 5%. [ABSTRACT FROM AUTHOR]

6. The need to balance the rotors of hammer crushers during operation in metallurgical production

Author

Kobrin, Y., Hrechanyi, O., Shevchenko, I., Mamuzić, Ilija, and Mamuzić, Ilija

Subjects
metallurgical production, hammer crushers, balance of rotors
Abstract

An experimental analysis of the infl uence of different amplitudes and frequencies of vibration on the technical condition of support units and parts and drive of crushers was carried out at the laboratory installation of the hammer crusher model. The dependences of the energy of destruction of coal and coke in the hammer crusher on the balance of the rotor are established. Installation of sensors for measuring vibration parameters allows to determine in advance the critical values of the crusher and to balance the rotor according to the proposed method, which allows not to dismantle it, which signifi cantly reduces maintenance and repair time.
