Happy viewing!!!
The process of crushing and grinding domestic product into powdered form was approached and achieved in this project work taking into account some necessary modifications due to the limitation found in the previous design machine. With the continuous improvement and advancement in the present days technology has brought the invention and making of diverse types and shapes of machine. These machines require different kind of energy for its operation and to produce useful work and it does not waste time. Most of them are operated manually or electrically. Basically, the pepper grinding machine is a useful device for achieving grinding of agricultural product like pepper food stuff and all type of grinding operations. In this grinding mill, the urge shaft is adequately supported with bearing to reduce the supporting materials. The posterior is also fabricated in such a way that there is room for adequate lubrication. These adequate supports given to the urge shaft help to reduce the frictional forces and there by ensures long lifespan of the machine. The materials used for the fabrication of this project are readily available and can withstand the mechanically applied force or stresses.

CHAPTER ONE
1.0 INTRODUCTION
The project titled fabrication of machine is used for grinding domestic food stuff like corn, pepper, beans, tomatoes, melon
e.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 body. It takes a lot of time and energy during operation (wwwcrushermachine.com).
Pepper grinding machine was fabricated purposely to overcome all the challenges which may be encountered when grinding using this primitive method. It can also be used for commercial purpose. Some of the machines were made to be operated manually. With this type of machine, series of labour is been done and a lot of energy been wasted in undergoing such task.
The advent of advanced technology has introduced a new dimension into this kind of grinder, which overcome the problem of hard labour and energy wasted with the use of the electrically operated grinding machine.
1.1 AIMS OF THE STUDY
The aim of the project is to fabricate pepper grinding machine to eliminate the olden methods of grinding. Electrical power grinder was put into the construction in order to ease the labour directed to the process of grinding and to limit time taken in the operation process.
1.2 OBJECTIVES OF THE STUDY
- To assess student interest and suitability in their respective career.
- To afford students the opportunity of relating the theoretical class works with the actual industrial life.
- To reduce the time taken and energy required during grinding operation.
1.3 UNITS OF A GRINDING MACHINE
The grinding mill is divided into four main units namely
- The hopper unit
- The crushing unit
- The power unit
- The collection unit
1.3.1 THE HOPPER UNIT
The hopper unit houses the food stuff to be grinded and guide the items in an hygienic manner to the crushing unit.
1.3.2 THE CRUSHING UNIT
The crushing unit consists of a space housing the shaft on which it is welded in a helical profile. When this shaft rotate, the welded helical profile move and crushes the food. The crushing staff converges the crushed food into the grinding pepper machine of the two discs.
One of the discs in the grinding units is stationary while the other rotates with the shaft in the crushing section. It is at this unit that the food is been grinded to fine particles. A ball bearing is incorporated and a screw ceases structure in other to contro’ the grinding efficiency of the disc.
1.3.3 THE POWER UNIT
An electric motor is fixed to the machine which helps to transmit output torque through a belt drive connected to the crushing shaft when the motor is on the shaft and have the operation of grinding machine.
1.3.4 THE COLLECTION UNIT
This is the point at which the grinded items would be collected after undergoing grinding processes.
1.4 LITERATURE REVIEW
CHAPTER SIX
CONCLUSION AND RECOMMENDATIONS
6.1 CONCLUSION
After the completion of the pepper grinding machine it was subjected to force indeed which the design was based.
Surely, adhering to the recommended and prescribed usage procedure applied the appropriate maintenance of every prescribed interval, a lengthy life span and best service is assured if precautions are timely taken as stated.
6.2 RECOMMENDATIONS
The major type of grinding machine being adopted is said to be the pepper grinding machine, the best service of this pepper grinding machine can be obtained by adhering to the specified recommendations which states that “ALL MOVING PARTS MUST BE PROPERLY LUBRICATED
Sharpening of the grinding disc at materials of at least two month depending on the late of use. Cleaning of the machine from time to time to avoid contamination of other food items.
