The attrition mill is a high speed mill with little capability for retaining coal. Therefore, fuel pockets cannot form and create a smoldering fire. If fire enters the mill from storage, detection could be made only by in frared detectors at the inlet. Because the product moves through the pulverizer in approximately 30 seconds,
at the kiln or mill shell at normal operating speed when the main drive is operating. • Full load running torque required at the kiln or mill shell at inching operating speed. Typically this is set at 120% of main drive operating torque. • The desired output speed at the shell. Usually this is targeted at RPM with a range of +50% / 10%
On the other hand, since coal is an unmeasured fuel, the control system is openloop, in which a fuel demand signal positions a coalfeeding device (speed variator of coal feeder) directly.

The amount of the recirculated gas depends on the required gas flow in the coal mill. The variable speed drive of the fan is regulating the amount of recirculated gas. The control loop for the fan is a constant pressure drop after the HURRICLON® system.
variable speed drives results in the following benefits. Optimized plant production By controlling a mill with a VSD, the speed of the mill is tuned for optimal grinding and maximum throughput, resulting in a more efficient use of the grinding power. If up and downstream processes require a lower grinding throughput, the mill can
the fan speed with a variable speed drive will change the fan characteristic itself (point of operation moves from position 1 to 3, see Fig. 1) without adding additional losses. The energy consumption can be reduced significantly. Energy efficient control of fans and pumps The control method employed has a major effect on the running costs.

Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.
Here are some basic equations that will help you understand the relationship between hp, torque, and speed. hp = (Torque x Speed)/5250 (eq. 1) Torque = (hp x 5250)/Speed (eq. 2) As an example, a 1hp motor operating at 1800 rpm will develop lbft of torque.

To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
