Designing The Crab Shell Crusher as an ingredient for The Teeth Restoration using Grinding and Sizing Method

Grinding is the process of reducing the particle size of processed material from a large (coarse) shape converted into a smaller size. For that whose name is grinding is the process of splitting or milling. Sizing is the process of leveling the sizes in a sieve according to the desired size so that the particle size becomes homogeneous. Making or designing a crab shell crusher machine using grinding and sizing system this requires clear design concept. This becomes very important because of the basic design of a machine that will guide the designer in making the tool. The
design procedure crusher shell crusher waste using grinding and sizing system, namely: literature study, design analysis, drawing work, procurement tools and materials, component manufacturing, and assembly of components. Then from experiment result from crusher waste crusher machine by using grinding and sizing system is obtained as granule ± 1 mm with an
average time of destruction 4 minutes 39 second (low rotation) and
2 minutes 36 second (medium rotation) for each initial weight 1 kg
of crab shells
