Design and Fabrication of Industrial Sand Screening Machine for Green Sand

Abstract

For the casting process, it requires sand as an important ingredient. Sand is used in green sand casting process for mold, core, runner and riser etc. in cope and drag. The sand screening machine is a machine that is used for sorting/ screening/separation of sand. The machine is work on the principle of rotary motion is responsible for the agitation (shaking) of the sand leading to separation of coarse particle from the required particle (fine and clean sand). The machine fabricated for casting process where the quality of sand increases the quality and finishing of the work. Sand is use in construction, manufacturing and many industries. Sand needs to be filtered and separated from unneeded particle, stones and other large particles before it are put to use. Our system puts forward a fully automated sand filtering and separator system that automatically filters sand poured on it. Here we use motorized shafts that are mounted horizontally using mounts. The shafts are connected to the filter frame with mesh below and enclosing frame on the side. We now have a rod connected from the shaft to the filter frame in a way such as to achieve best horizontal motion at the same time. ON switching on the motor using our motor controller circuit, the system allows to operate the motor. This allows us to operate the sand filter motion for appropriate sand filtering needs. A sand scanning device for separating wanted element from unwanted material or for characterizing the particle size distribution of a sample, typically using a woven screen such as a mesh or net. This project focuses in design, fabrication of the mechanical part of machine and the system of the sieve machine. To achieve this project objective, this sieve machine body structure and mechanical system needs to concern some other criteria such as strength, safety and ergonomic design.
