Abstract: A quarry pulverizer for use as a reduction process machine for rocks and mineral bearing ores is provided for use. The purpose of the quarry pulverizer is to enhance the ability to meet product grading requirements without adding cost or time to the operation, to reduce maintenance costs associated with these types of machines, to increase feeding capacity, to demonstrate how a centrifugal reduction machine can eliminate wear to its central rotor, and to present a pulverizer with an overall modular design that can be tailored to meet a customer's needs. The invention also introduces the concept of how a static impact area may be changed into a dynamic impact area and subsequently increase reduction efficiency. A quarry pulverizer is provided to act as a reduction process machine for rocks or mineral bearing ores.

Abstract: A coffee grinder for discharging ground coffee into a brewing funnel which will be removed and inserted into a coffee making machine.
