My aim behind desiging this machine was to make easier and faster work for the worker working at the construction site. This machine consists of the 3 level screen system, which is used to separate different grades of material like coal, pebbles, agricultural material and etc.

This system or machine works on the principle of cam and follower arranged which is easy to construct and cheaper in cost because I used scrap material for it. 

This very light weight machine compared to other machines present in todays market. machine vibration are controlled by foot speed regulator. We can also the change the screen for different purpose according to the requirement.
