Kinetic energy when the steel ball falls

The steel ball drops the energy of the impact ore from the kinetic energy it reaches at the end. The magnitude of this kinetic energy is determined by the falling height of the steel ball. The speed of the mill determines the falling height of the steel ball, so the method of determining the speed of the mill is directly related to the analysis of the kinetic energy of the falling of the steel ball.
It can be seen from Fig. 1 that the absolute value of the falling height H of the steel ball is

Figure 1   The velocity of the ball at the end of the parabolic path and its component
The absolute value is:

Pour Ï… x and Ï… y into the tangent speed Ï… t direction, then
According to the above method, Ï… x and Ï… y are substituted, and after simplification and finishing,
The tangential velocity Ï… 1 and the normal velocity Ï… n are different in the direction and size of different landing points, as shown in Figure 3-2-12. It can be seen from the figure that the greater the rotational speed of the mill, the higher the rise of the same layer of balls and the smaller the angle of departure. When the angle of departure is ,, the speed of the ball is 75%, Ï… t =0, and Ï… n = Ï… P , the tangential speed is changing direction, and the Ï… n of each falling point is known to calculate the impact ore.

Smooth Surface Pillar Candle

Types of Pillar candles

There are many different kinds of pillar candles as described above, the categorization is done on the basis of shape, wick,materials and scent.


Basic Pillar Candle:

It is cylindrical in shape, having a single wick. It is made of paraffin or beeswax, having different colors. It can be decorated on the dining tables.

Soy Pillar candles:

As the name suggests the candle is made of soy and some other components which help to give the stability to the candle. They are quite eco-friendly and burn much hotter than the conventional candles.

Layered Pillar Candles:

These candles are quite similar to basic candles, but have layers of different colors in its wax.It is best to use for decoration purpose as it can give quite a dramatic affects in the room.

Ice pillar candles:

This name to these pillar candles is given due to its formation technique, as ice is used to make these candles and while burning it creates an enchanting lighting pattern.

LED Pillar candles:

This candle is quite opposite to the conventional candle as there is no melting of wax or the burning of wick. It is also called as the flame less candles. It is purely used for the purpose of decoration and home designing.
