The paper presents a new method of determining the energy consumption for vibratory crushing. Using the laboratory vibratory jaw crusher with kinematic actuation of the jaws, the study of determining power consumption while crushing limestone and diabase was conducted. During the study, electrical energy used on the crushing process was measured as a function of changing design and kinematic parameters of the vibratory crusher, i.e.: jaws stroke, the outlet gap size and frequency of jaws vibration. The article pre...

Very fine crushing of hard and very hard materials, to product of particle size less than 2-4 mm at feed particle size of 50-200 mm, requires a very large energy inputs. This is mainly because of the need for at least three or even four degrees of crushing, containing: jaw, cone or impact crushers. One of the methods of reducing the amount of energy expended on the crushing process is reducing the number of crushers in technological line. By replacing a large number of less effective crushers with fewer machines b...

The basic purpose of magnetic separation is to separate the ferromagnetic elements from the magnetically inert component. In difficult conditions of mining activity, due to high costs of repair or replacement of damaged machine elements, prevention related to the correct operation of machinery and equipment of production lines is particularly important. Safety systems of feed material (electromagnetic separators) are designed for installation on construction of a conveyor belt to clean the transported material fro...

The article presents results of using vibratory jaw crusher for feed preparing for the granulation process. The main aim of the study was to determine the possibility of preparing the limestone feed for non-pressurized granulation process by means of very fine crushing in the laboratory vibratory jaw crusher KW 40/1 with kinematic actuation of jaws. The crusher is characterized by high average degree of fragmentation (30-50). The study was conducted in two stages. The first stage included experiments with vibrator...
