Abstract

A manually operated oyster shell crusher was fabricated and evaluated. The crusher consists of two knurling rollers, two gears, two bush bearings, two adjustment bolts, one handle, one hopper and a tray. When the crushing rollers was powered by hand through a handle, the oyster shell as received through the hopper was crushed by the rotating rollers. The performance tests indicated that the device could crush 17.80, 7.51, 3.7 3.76 kg/hr in Ist phase of reduction, 2nd phase of reduction and 3rd phase of reduction, respectively. The average efficiency of the device was found to be 97%. The crusher can be used for crushing of oyster shell, snails etc. with high satisfaction.
