stockpiled. Figure 2-1 is a flow diagram of crude ore processing. The first processing step is to reduce the diameter of the ore to approximately 1.6 centimeters (cm) (0.6 inch in.) in a primary jaw crusher. The crude ore is then passed through a rotary dryer, which reduces the moisture content from between 4 and 10 percent to less than 1 percent.
Stationary plate regenerative air-pre heater - The plates or heating elements are stationary in this case as compared to a rotating air preheater. Instead, the ducting system of inlet air and outlet air is made rotary so that all the plates are exposed to both hot and cold air. Such an air-pre heater is also known as Rothemuhle Air-pre heater.

Heating combustion air can raise boiler efficiency about 1% for every 40F in temperature increase. The most common way to preheat the air is with a heat exchanger on the flue exhaust. The heat exchanger can be either air-to-air or air-to-liquid-to-air. Combustion air pre-heater technology on large coal-fired boilers dates back to the early 1900 ...
