Grinding Mills - Common Types
The Hardinge mill, Fig. 1.7, uses spheres as a grinding agent but the body is of cylindro-conical form and usually has a length to diameter ratio intermediate between those associated with the ball mill and the tube mill. The reason for this form of construction is that it is found that, during, the operation of the mill, the largest balls ...

6.8 The Divergence Theorem - Calculus Volume 3 | OpenStax
The divergence theorem confirms this interpretation. To see this, let P be a point and let B r B r be a ball of small radius r centered at P (Figure 6.89). Let S r S r be the boundary sphere of B r. B r. Since the radius is small and F is continuous, div F (Q) ≈ div F (P) div F (Q) ≈ div F (P) for all other points Q in the ball.

Ball Mill - British Rema
Conical Ball Mills Used wet or dry, closed or open circuit, conical ball mills provide a classifying action within the body of the mill due to particles of greater size tending to reside at a point of greater diameter. This characteristic delivers increased efficiency and lower power consumption. Conical mills may also be air-swept when run dry.
Chapter 29 – Electromagnetic Induction
i.e. away from the coil's magnetic field. Then, for a conical coil (smaller radius at the bottom than at the top) the metallic sample will move upward due to this levitation force, until the force of gravity balances the force of levitation. (The levitation force is larger at the bottom of the conical coil than at the top of the coil).

To get an idea of the shape of the surface, we first plot some points. Since the parameter domain is all of we can choose any value for u and v and plot the corresponding point. If then so point (1, 0, 0) is on S.Similarly, points and are on S.. Although plotting points may give us an idea of the shape of the surface, we usually need quite a few points to see the shape.
