[0002] Users of conventional spice grinders and masala mills often encounter problems such as motor overheating, interrupted grinding due to overload, and inconsistent grinding performance. These issues are especially prevalent when grinding coarse or hard ingredients such as dry spices, herbs, and masalas. Most grinders available today are equipped with simple mechanisms that either automatically require manual operation when the unit jams or simply shut off due to excessive heat. This interrupts the grinding process, requiring the user to allow the unit to cool down before continuing.

[0003] In addition, constant grinding at high speeds creates a lot of friction and heat, which leads to motor overheating and wear. This can lead to constant breakdowns and a shortened lifespan of the machine. For anyone grinding large quantities of spices, such as in commercial kitchens or spice factories, these interruptions and the need to manually restart can be time-consuming and inefficient.
