Abstract
The article deals with the method of hydromechanical extraction of amber from sand deposits. The essence of hydromechanical method of amber extraction is considered. The process of extraction has been identified. The analytical expressions obtained for calculating the parameters of hydromechanical extraction of amber from sand deposits, and in particular the expression for determining the rate of emergence of an amber particle, can be used in the further engineering calculations of process parameters and process equipment. These expressions will allow to accurately substitute and with sufficient accuracy to calculate the parameters of the process of extracting amber from amber-containing deposits, as well as to set the parameters of technological equipment for the implementation of this process.
Highlights
The essence of the above method is that the array is saturated with water and activated by mechanical excitation to form a continuous slurry of such density at which there is an ejection force that raises the amber on the surface of the deposit
It is necessary to dip the rods in the amber array in the form of pipes from which water and air are supplied and on which mechanical exciters are fixed
Amber separates itself from the massif and under the action of ejection force floats to the surface
Summary
The essence of the above method is that the array is saturated with water and activated by mechanical excitation to form a continuous slurry of such density at which there is an ejection force that raises the amber on the surface of the deposit. Mechanical action, when present in an array of water, causes the array to completely lose the bond between the particles, release the amber and reach a suspension state with a density greater than the specific gravity of the amber, which allows the latter to float to the surface of the field at the expense of the field. The array of vibrators is oscillated, forming a zone of continuous boiling of the soil. The suspension medium allows the vibration device to move freely in the longitudinal direction
