why we get attracted towards this sand screening machine. SAND SCREENING MACHINEIt mainly consists of a fabricated divergent drum type structure on which a screening mesh has wound. This structure is mounted over a central shaft with the help of square bar spokes. This shaft is supported in the roller bearing on the two ends which are mounted on the M.S. angle structure. A hopper mounted on same structure feed sand in the small opening of rotating drum. This drum is driven by an electric motor, through worm & worm wheel. As sand flows from small opening to big opening it gets screened & unscreened sand comes out from big end, & can be collected separately.
methods are used for screening the sand. Its rate of screening is very low and it is time consuming. It also has great limitation for wet sand & requires more man power. Scarcity of labor is one of the biggest problems in construction business. Because of above limitation of traditional method we were inspired to manufacture a machine which will solve above limitation. The machine which we have manufactured for screening the sand is known as “Rotary Sand Screening Machine” Sand screening machine mainly consists of a fabricated divergent drum type structure on which a screening mesh has wound. This structure is mounted over a central shaft with the help of square bar spokes. This shaft is supported by the pedestal bearing on the two ends which are mounted on the M.S. angle structure. A hopper mounted on same structure feed sand in the small opening of rotating drum. This drum is driven by an electric motor, through worm & worm wheel. As sand flows from small opening to big opening it gets screened & unscreened sand eliminated out from big end & can be collected separately.
2. Design and Development Phase The meaning of design is the creation of new and better machines which are more economical in the overall cost of production and operation. From the study of exiting ideas, a new idea has to be conceived. The idea is then studied keeping in mind its commercial success & given shape & form in the form of drawings. In the preparation of these drawings care must take of the availability of resources in money, in men & materials required for the successful completion of the new idea in to an actual reality. In design there must be satisfaction of human needs. In the previous chapter, the need for developing sand screening machine has been clearly stated. & here onwards, starts the actual design & development phase.
1.INTRODUCTION In the todays advanced technological world construction work is tremendously increased. It needs all the works involved in has to carry out by machine automatically. The sand screening is one of the processes which are being carried out by the conventional means till today. It is carried out by rectangular frame holding screen in it & keeping inclined to the ground & with the help of man power. Its rate of screening is very low & time consuming. It also has great limitation for wet sand. It also requires very much man power. In most of the large & medium construction work, lot of sand has to be use after screening & the conventional devices are insufficient uneconomical to serve their purposes. It requires lot of time because a worker has to pour sand slowly on the inclined screen by providing reciprocating motion to his hand. Also perfect (100%) screening is not obtained i.e. a large amount of useful sand goes waste through unscreened sand. So it also requires a double or triple screening depending on the conditions. The screen also gets damaged after a short period of use, so it fails to serve purpose of screening. Also it has great problems for wet sand. To overcome all the problems, we thought to provide such a machine which is free from any

There are no unique dimensions for any component. It is meaning less to request the correct answer to design problem, because there is none. But design is a way to approach the reliable dimensions. No matter what words are used to describe the design function, in engineering it is till the process in which scientific principles & tools of engineering are used to produce a plant or a system which when carried out, will satisfy a human need.
3. WHAT IS THE SCREENING MACHINE? A fabricated taper drum shaped structure made from MS strips it has an increasing cross-sectional area throughout this length .It is mounted on a central hollow shaft, with the help of MS square bar spokes. This is to assure firmly holding the drum on shaft screening mesh is wound on the drum & clamped.
