Combined type settling leg is used for the method for settling character research, comprises the following steps.
A. each arm of settling leg is sealed with emulsion tube and clip; Raw material mixes in advance, by feed ore concentration requirement preparation ore pulp.
B. the ore pulp prepared in advance is fed in combined type settling leg, to certain scale, add flocculating agent on request again, stir up and down with stirrer, writing time and negative area mud line scale, carry out the mensuration of static settling velocity by common settling velocity assay method simultaneously, after mensuration terminates, sample from the arm of the foot of foundation, then weigh, dry, weigh again, compression zone underflow density under mensuration static condition.
C. adopt peristaltic pump to be given by feedstock pump in combined type settling leg, feed limit, limit adds flocculating agent on request simultaneously, and the arm of the foot of foundation connects a underflow pump and carries out discharge, thus can realize the dynamic process of continuous-feeding continuous pulp discharge.By controlling the discharge velocity of underflow pump and the delivery rate of feed pump, and then mud line height in compression zone in dynamic settling process can be controlled, under controlling the condition identical with static settling height, after dynamic circulation same time, access underflow pump sample, then weigh, dry, weigh again, measure underflow density, i.e. compression zone underflow density under dynamic condition.
Beneficial effect of the present invention: 1, effectively solve the situation that Static and dynamic cannot effectively contrast; 2, the impact of ratio of height to diameter on settling property can be detected; 3, the impact of compression zone differing heights on settling property can be detected.

Embodiment
Composition graphs 1, Fig. 2, be described in further details the present invention.
Combined type settling leg, comprises foundation 1, built-up pillar 2, base 3, scale 4, LED 5, stopple coupon 6 and flange 7, it is characterized in that: foundation 1 upper end open, lower end closed, built-up pillar 2 upper end, the equal opening in lower end; Foundation 1 lower end is fixing on the base 3, and there is flange 7 upper end; All there is flange 7 top and bottom of built-up pillar 2; Foundation 1 and built-up pillar 2 are all evenly distributed with some stopple coupons 6; The outer wall of foundation 1 and built-up pillar 2 has scale 4; Respectively there is a LED 5 side on the base 3 and near scale 4 on flange 7; On scale 5, existing height groove has again volume groove.
Combined type settling leg is used for the method for settling character research, comprises the following steps.
1, the difference of compression zone concentration under tested static and dynamic condition.
A. each arm 6 of settling leg is sealed with emulsion tube and clip; Raw material mixes in advance, by feed ore concentration requirement preparation ore pulp.
B. the ore pulp prepared in advance is fed in combined type settling leg, to certain scale, add flocculating agent on request again, stir up and down with stirrer, writing time and negative area mud line scale, carry out the mensuration of static settling velocity by common settling velocity assay method simultaneously, after mensuration terminates, sample from the arm of the foot of foundation, then weigh, dry, weigh again, compression zone underflow density under mensuration static condition.
C. adopt peristaltic pump to be given by feedstock pump in combined type settling leg, feed limit, limit adds flocculating agent on request simultaneously, and the arm of the foot of foundation connects a underflow pump and carries out discharge, thus can realize the dynamic process of continuous-feeding continuous pulp discharge.By controlling the discharge velocity of underflow pump and the delivery rate of feed pump, and then mud line height in compression zone in dynamic settling process can be controlled, under controlling the condition identical with static settling height, after dynamic circulation same time, access underflow pump sample, then weigh, dry, weigh again, measure underflow density, i.e. compression zone underflow density under dynamic condition.
