The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.

4.2.1 Rough grinding machines The rough grinding machines are used to remove stock with no reference to the accuracy of results. Excess metal present on the cast parts and welded joints are removed by rough grinders. The main types of rough grinders are: 1. Hand grinding machine 2. Bench grinding machine 3. Floor stands grinding machine 4.

A range of dehulling machines (both manual and powered) are available. After dehulling, the seed is winnowed to remove the husk or seed coat from the kernel. Traditionally, winnowing is carried out by throwing the seeds in the air and letting the husks blow away. For higher rates of production, winnowing machines (manual and powered) are available.

machines from paddy to white rice. 3.1 One pass milling Pestle and mortar Hand pounding of paddy in a mortar with a pestle is still practiced in some remote areas. Pounding the paddy induces upward and downward forces on grain against grain that removes the husk and some bran layers. The pounding also results in a high percentage of broken kernels.
