Ore nature and shape of the mine (5)
(4) The cross section of the common body of the warehouse body has a circular, square and rectangular cross section. The shape of the cross section of the silo has no effect on productivity, it only affects the type of flow of the material. When the cross section is circular or elliptical, if the silo is constructed to accommodate the overall flow surface, the individual layers of the stored material will move horizontally downward. If the cross section is square or rectangular, the material in the four corners flows slowly, so it is considered to be a poor overall flow type; this disadvantage is even more pronounced if the bottom of the tank is flat (no bucket). (6) The geometric volume of the mine bin The geometric volume of the ore in the mine bin is determined by its stacking angle, the angle of collapse (or the angle of inclination of the bucket) and the shape of the silo. The sum of the geometry of each rule formed by these conditions is the geometric volume of the mine bin. As shown in Figure 15, its volume: If the blanking point is eccentric, the R and H forming the cone are different. But the same can be done with reference to the above principles. 1.Independent electric screw drive brings you both plasticization and energy efficiency Injection Molding Machine,Pet Preform Injection System,Fully Servo Pet Preform Injection Machine,Hight Speed Preform Injection Machine Demark(changxing)injection system CO.

(V) Studies conducted by the embedded bodies Kvapil and Tanaka show that when handling free-flowing loose materials, inserting an insert above the discharge opening (Fig. 14) can obtain a larger flow band. This type of device works well in coal storage bins. But especially for those metals mineral coarse iron ores due to their extremely abrasive, the use of the inlay, with predictable results.

V=V 1 +V 2 +V 3 (14)
If the cross section of the mine bin is not circular but rectangular, the shape of V1 is as shown in Fig. 15. Its calculation formula is as follows:
V 1 =V P -2(V' u +V" u ) (15)
V P is a cone whose diameter is the diagonal of the cross section of the mine bin, so VP is not difficult to calculate.
V u is one of the four cones that V P is cut by the four side walls. If it is a square mine, then:
