Vertical centrifugal casting machinery spins parts about a vertical axis. Parts are commonly of shorter height than diameter. The great benefit of spinning about a vertical axis is that practically any size and shape of casting can be spun about a vertical axis. Common castings poured in vertical machinery are rings and ball valve balls.

Roller mills use the centrifugal force of cylindrical grinding rolls to crush material into a uniform particle size and grind, dry, and classify. Some of its typical applications include the grinding, drying, and classifying coal, gypsum, limestone, clay, barite, pearlite, clinker, food products, grains, ores, and more.
Our flagship mills are centrifugal ring-roll pulverizers – equipped with three pendulum roll assemblies suspended from a rotating carrier. Centrifugal force created by the rotation of the carrier forces the roll assemblies to swing outward, causing the roller at the bottom of the roll assembly to rotate against the inside of the stationary ring.

In a typical vertical spindle pulverizer (Figure 1), raw coal is fed through a central coal pipe at the top of the pulverizer and falls by gravity to the rotating grinding table, mixing with classifier rejects returned for re-grinding. Centrifugal acceleration forces the
The working principle of vertical roller mill: ... Subject to centrifugal force, fluid resistance and self-gravity, the coarse powder larger than the converging point falls back to the plant area. The central cone of the mill is ground again together with the pellets. The graded fine powder that meets the fineness requirements is used as the ...
Vertical Centrifugal Castings. The JCT vertical centrifugal casting process guarantees the highest quality metal components, through pouring liquid metal into a rapidly rotating die.
Figure 3.1: Horizontal and vertical position of kernal nuts 26 Figure 3.2: Compression of kernal nut using UTM The cracking of the kernel nut was quasi-statically compressed until the nut breaks and cracks as shown in figure 3.3.
The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.
Centrifugal Force: Centripetal force is the component of force acting on an object in curvilinear motion which is directed towards the axis of rotation or centre of curvature. Centrifugal force is a pseudo force in a circular motion which acts along the radius and is directed away from the centre of the circle.
