According to research on the kinematic characteristic curve of the Haoxing mineral processing technology expert, the motion characteristics of a shaker can be illustrated using either actual measurement techniques or graphical algorithms. The actual measurement method involves connecting displacement and velocity sensors to the shaker, allowing for direct plotting of displacement, velocity, and acceleration curves via an oscilloscope. This approach provides real-time data that reflects the physical movement of the system.
On the other hand, the graphical algorithm is based on the geometric relationships within the bed head components. It starts by generating a displacement curve using a map-like representation, then applies function approximation methods to develop a mathematical model. From this model, velocity and acceleration equations are derived and plotted accordingly.
The differential motion of the shaker is primarily evident during the acceleration phase of its forward and backward movements. This can be evaluated by measuring the time it takes to cover the same distance in both directions. Two asymmetry coefficients, E1 and E2, are commonly used as indicators of this behavior.
E1 is calculated as:
E1 = (Time for the first half of the forward stroke + Time for the second half of the backward stroke) / (Time for the second half of the forward stroke + Time for the first half of the backward stroke) = t1/t2
Similarly, E2 represents another aspect of motion asymmetry, and when E2 > 1, it indicates that the forward process takes longer than the return stroke, reducing the chance of particles sliding back. Comparing E1 and E2, E1 is considered more significant as it reflects the strength of the quick return movement of the bed surface.
In coarse ore selection, typical values are E1 = 1.88 and E2 = 1, while for fine ore, E1 = 1.88 and E2 = 1.24 may be more suitable. If both E1 and E2 equal 1, the displacement curve becomes sinusoidal, and the particles only oscillate in place without any net movement.
This detailed analysis helps optimize the performance of the shaker, ensuring efficient mineral separation and improved processing outcomes.
