PROJECT PRESENTATION ON
BAT KNOCKING MACHINE

2. INTRODUCTION
• A significant portion of this preparation can be best
performed by our pressing machine along with a ball mallet
or bat mallet. All new cricket bats must be “knocked in”
before they are ready for use on the field, according to
middle peg cricket equipment. Knocking in a cricket bat
properly should take about six hours.
• Allow the soft fibre to strike a hard NW cricket ball.
• Reduces the risk of the bat snapping.
• knocking of bat fills in the gaps between the fibre
• Our Cricket Bat Knocking Machines are available in Best &
World-Class quality with very reasonable price.
• It reduces time for knocking bat.
• It makes the knocking of bat faster.
• It makes the knocking of bat accurately in less time.

3. WORKING OF PROJECT
• To knock in a cricket bat, use a bat mallet expressly designed
for this purpose. Knock the bat lightly against the edges of
the bat, using increased force as you work toward the centre
until the edges of the bat are uniformly smooth and round a
cricket ball lightly up and down on the face of the bat.
• We are involved in offering high quality cricket bat knocking
machine. All bats are pressed by the manufacturer, knocking
in is must for the survival of your bat .it is the process by
which the fibers of the willow in the face and edges are
compressed together to form a barrier which protects the
against impact of the ball. Effective knocking in will
significantly improve the performance and increase the
lifespan of the bat. We recommend that prepared ready play
and pre knocked in bats need extra preparation and care
before use. A significant portion of this preparation can be
best performed by our machine along with a ball mallet or bat
mallet.

5. Bat knocking is done automatically.
Bat knocking machine reduces knocking time compare to
manual bat knocking .
Earlier by manual bat knocking equal force on bat was not
implied but by the use of bat knocking machine equal force is
exerted on bat which results in accurate knocking of bat.
Bat knocking increases the strength of the bat.
ADVANTAGES

6. DISADVANTAGES
 Bat knocking machine need proper foundation.
 In bat knocking machine there are sometimes chances
to be snapping of bat.
 Machine can`t run without electricity.

7. APPLICATION
• Bat knocking machine is used to knock bat accurate with equal
force exerting on the bat.
• Bat knocking machine is widely used in BCCI.
• It reduces time for knocking bat.
• It makes the knocking of bat accurately in less time.
• Reduces the risk of the bat snapping.
• knocking of bat fills in the gaps between the fiber

9. CONCLUSION
We conclude that by better utilization of bat knocking
machine brings us too many benefits like reduces knocking
time, accurate knocking, reduces labour work, eliminates
manual knocking.

1. SPRING FORCE
F=K.X
K= (G.d2) (8nD3)
k= spring stiffness
• d= wire diameter
• D= mean coil diameter
• n= number of active coils
• G= modulus of elasticity
X= spring stretch
2. FORCE = m g
m= mass
g=gravity
TOTAL FORCE ON THE BAT = Spring force + m.g

23. 1. SPRING FORCE
F1=0.1096 40 cos45 = 3.09995N (spring is connected at 45 )
K= (G.d2) (8nD3)
k= 0.1096
• d= 1.15mm
• D= 18.20mm
• n= 50
• G= 200 103 mpa
X= 40mm
2. F2 = 0.156 9.81 =1.53036N
m= 0.156g
g=9.814
TOTAL FORCE ON THE BAT = 3.09995 + 1.53036 = 4.63031N
