height PE = h,
Using the phthagoras theorem /BE/^2 =/PE〖/ 〗^2+/PE/^2 ……..(i)
/PE/^2 = /BE/^2 - /PE/^2
PE = h
〖h 〗^2=100^2-50^2
〖h 〗^2= 10000 -2500
h^2=( 7500)/7500
h =86.60mm
Total volume of the pyramid
= 1â„3 x Area of base x height
= 1â„3 x Area of square x ABCS x (H + h)
=1â„3 x (350 x 350)x(272.72 + 86.60)mm^3
=1â„3 x (122500) x (359.32)
=14672231mm^3
Volume of the smaller pyramid
1â„3 x Area of base x height………….(iii)
1â„3 x Area square A’B’C’D x h
1â„3 x (100 x 100)x (86.60)
= 1â„3 x (10000 x 86.60)
= 288666.63mm^3
Now d1 = 500mm
Now d2 = 200mm
Then; VR =d1/d2 =500/200 = 1.4
Although N1 =1400 r.p.m
Hence N2 = (VR x N)
= 1/ X 1400
= 350 rpm
The required volume of the hopper = total volume of the pyramid — volume of the smaller pyramid
= 14672231—288666.63
= 14383565mm3
4.2 MASS OF HOPPER
Density of mild steel plate = 7.85 kgm3
Volume of the hopper = 14383 565mm3
Mass of the hopper =?
Using the formula
mass
density = (m,ass)/volume ---------------(i)
Okeke P. N and Anyakola M. W (2011)
7.85 = mass/14383565
mass = 1.12910998
mass = 1.129kg

CHAPTER ONE - [ Total Page(s): 1 ]CHAPTER ONE1.0 INTRODUCTIONThe project titled fabrication of machine is used for grinding domestic food stuff like corn, pepper, beans, tomatoes, melone.t.c. The grinding operation was carried out in the olden days with the aid of grinding stone. This method is very tedious and unhygienic in nature. The particle of the grinding stone can easily be mixed with the grinding food items which may be hazardous to the food itself and also to the personnel undertaken such task by entering his or her bod ...

CHAPTER TWO - [ Total Page(s): 1 ]CHAPTER TWOANALYSIS OF ALTERNATIVE METHOD TO GRINDING MACHINE2.1 MANUAL GRINDING MACHINEThe
manual grinding machine is a model of all grinding machine and it is
small and occupies a little space. It has a stand that saves its shock
absorber. Wonder is connected to the shaft through to the power input is
transmitted when the food is dropped into the wonder the wonder will be
conveniently okay. The shaft crushes it before transferring into
grounding unit where it will be grinded before ... Continue reading---
CHAPTER THREE - [ Total Page(s): 1 ]CHAPTER THREEGENERAL DESCRIPTION AND IT WORKING PRINCIPLE3.1 HOPPER UNITThis is a place where the food product to be grinded, is pour to it, made up of mild steel of 2.4mm thickness. From this unit the food moves to crushing units.3.2 CRUSHING UNITIt comprises of the worm and rotating shaft. The worm is constructed from a pipe and cut to be required shapes and sizes of 135mm by 700mm diameterA portion was cut off to the dimension. The cut made to the worm is to make it well inserted and we ... Continue reading---
CHAPTER FIVE - [ Total Page(s): 2 ]THE COLLECTION UNITThis unit houses the grinding does and it is made of mild steel sheet aid are welded together.An
adjust nut and handle is assembled at the external part of it to
control the operation of the grinding disc for. The construction of the
adjusting nut and handle shaft was gripped in table rice threaded to
make room for used key, while the bushing connected to the cover face of
the unit was threaded too.The grinding is however not limited to the above parts alone. It comp ... Continue reading---
