In the work of the 6S table to which a few self check?

According to the characteristics of gravity materials, tabling is not the same with other processing equipment, the movement rule is always the purpose of the study, described the table motion characteristic curve can be measured method or graph algorithm. The measured method is the displacement and speed sensor is connected to the table, through the oscilloscope to depict the displacement, velocity and acceleration curve. Map algorithm is based on the bed in many parts of the scale, displacement curve drawing the first request bit, and function approximation method to establish a mathematical model, and then push the equation of velocity and acceleration are derived and plotted.

The primary differential movement in the period before and after the table reflects the movement change is not the same acceleration, so we can use the same operation interval of time required to evaluate different, often using two kinds of asymmetry coefficient j5}l and E2 criterion (see Figure 11 - 5 - 4).

E1= the time required for the first half of the bed (the first half of the bed and the second half of the retreat), the time required for the second half of the bed and the first half of the retreat (=t1/t2).

The second half of the bed after the request to slow down and rapid exhumation, while the latter half of the retreat is slow to return, it is always t1>t2, E1>1. When E2>1, it indicates that the bed surface is long, the time is short, and the possibility of sliding back to the particle is reduced. Compared with E2, E- shows that the bed surface is strong and fast, so E1 is more important than E. In the election of coarse, granular ore desirable E1=1.88, E2=1, selected fine ore E1=1.88, E2=1 * 24 more appropriate. If E1 and E2 are equal to 1, the displacement curve becomes a sine curve.
