A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions. The classification function plays the important role of ensuring that only fine particles are sent to the boiler.

Drives using gears should be called gear drives because a gear drive may not have a box (enclosure). However, as gear drives are commonly called gearboxes, I have used gearboxes instead of gear drives in chapters 1 7 of Part 2 and in the title. For information on the following, please view Part 1 Use of Gear Drives
Manufacturing limitations from gear vendors determine the minimum number of pinions which can be used to drive the mill as well as the number of gear sections. If the mill requires approximately 6000 horsepower or less, it is possible to drive it with a single pinion. To date, however, economics has dictated that most mills over 3500 horsepower ...
The cost of edge drive is low, but the pinion needs to be replaced every 25 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

Wang et al. [ 4] optimized the coal mill by minimizing the energy consumption using a neuralnetwork model and genetic algorithm. They built a radial basis function (RBF) neural network model, which used the main factors that affected the power consumption as input variables, for determining the energy consumption.
Smart vertical roller mill design for raw, cement and slag grinding. The OK™ Mill was originally designed for cement grinding. In 2017 we released the OK™ vertical roller mill for raw materials grinding. The OK™ Mill's modular design comes with unique flexibility, showcasing parts commonality, where spare parts can be shared between ...
With adequate mill grinding capacity, the MPS mill equipped with SLK static classifier is capable of producing a coal fineness up to % or higher <50 mesh and 80% or higher <200 mesh, while the SLS dynamic classifier produces coal fineness levels of 100% <100 mesh and 95% <200 mesh, or better.

An ISO 460 VG gear oil in a 275gal. sump in a coalpulverizer gearbox filtered with a 6 micron absolute filter at a flow rate of gpm produced the results in Table I. In many cases, if the correct filter is selected, the target cleanliness can be reached quickly depending on the size of the reservoir and the flow rate though the system.

From the coal yard, the coal is transfer to the mill bunkers through conveyor belt. The bunkers are sized for an effective capacity of twelve (12) hours at BMCR with design coal. Each mill bunker has one hopper, connected to the feeders. Mills operate when the bunker coal gate valves are opened, coal is allowed to flow to the gravimetric feeders.
