The actual measurement shows that the above flow velocity distribution calculation formula is more accurate than the exponential equation.
B. Turbulence of the turbulent flow of the turbulent flow + turbulent diffusion The disturbance of the water flow in the turbulent flow is the main factor of the loose bed, called "turbulent diffusion". The instantaneous velocity of a point in the slot is decomposed into three components, normal and lateral, along the longitudinal direction of the slot, and the instantaneous velocity in each direction deviates from the average velocity (zero in the normal and lateral directions) as the instantaneous pulsation velocity. For loose beds, it is mainly dependent on the instantaneous pulsation speed of the normal direction. Its time rms value is called the normal pulsation velocity.

The normal pulsation velocity is not consistent along the water depth. In the lower initial vortex formation zone, the pulsation velocity is stronger and gradually increases upward.
The ore group maintains loose suspension in the turbulent sloping flow by the normal pulsation velocity, and in turn the particle group inhibits the pulsation velocity, so the turbulence of the slurry membrane is always weaker than the clear water film. This phenomenon is called the "depletion effect" of the granules.
At the bottom of the turbulent slurry flow, the concentration of solid particles is large and the flow rate is significantly reduced; the upward flow rate is sharply increased, even to the top exceeding the flow rate of the clear water flow. However, the flow velocity distribution of the slurry flow still follows a logarithmic relationship:

The average flow velocity of the slurry ramp flow is still close to the flow rate of the clear water slope flow at a lower concentration, but decreases sharply as the concentration increases, as shown in FIG. [next]

3. Sorting of ore in thick turbulent sloping flow The turbulent sloping flow in thick water layer mainly treats coarse and medium grain (>2 mm) ore. The device is usually a straight, inclined slot. In order to effectively loosen the bed and retain heavy minerals, baffles or rough coverings are often placed in the tank. During the movement of light and heavy minerals along the bottom of the tank (or sediment), heavy minerals remain in the tank. Light minerals are discharged outside the tank to achieve separation.
The speed equation for the movement of particles along the groove is: [next]

Crane Rail

The crane rail is what guides a crane to travel along the pre-designated route while transferring pressure energy coming from wheels to the foundation where the rail is built. It mainly comes in three types: heavy, light and specialized.
