CHAPTER ONE
The machine was initially designed before fabricated purposely for gravel separation, it was frame with angle iron with measurement to 6inch which carry the machine,
Secondly construct the collection tray with apartment after welded.
Thirdly, the bearing and bearing housing attached rotation of cylinder drum through help of shaft / handle. The shaft (mold started) used to guide cylinder drum before pass through baring and weld handle, the cylinder drum was perforated for serves diameter the 10mm, before finally assemblage the pars.
The main problem is the cost and is considering to importing foreign machine increases foreign economy while our economy reducing at the same time, in respect to performance, early manual gravel grading machine is imperfectly to separate gravel aggregates before after successful research made through constructing it by mechanical services to affair a required separation. It usually manual operation which consume greatest energy and from the machine tear and minced with gavel as a result of irrelevance material used of fabricate. As a problem it has noisy obratian and breading of bigger particles on smaller services to prevent pass.
The objection of the project is to acquire expertise in the construction of manual gravel grading machine and further having different size of gravel aggregates which hell builders in building construction in chosen the comet particle, it is also to remove unwanted coarse and pure from impunities, where the objective of this project is to provide an efficient of high work done.
Before, builder used mixed of different sizes of gravel to build but now, manual gravel grading machine is using to separate gravel aggregate according to sieves for specific used about diameters of 6mm, 10mm and /10mm and separate particles of impunities from gravel aggregate. It improves building technology and very cheap to maintain with the used of these machine it serves time and operates without used of any chemical energy which totally reduces labourers
