Southwestern's primary business is the design, manufacture and servicing of performance modifications and upgrades for coal pulverizers. Our work force is experienced and familiar with the requirements and demands of our electric power generation and cement plant customers. As a result, customer service is our top priority.

Coal pulverizers wear liner is used to protect the cylinder from direct impact and friction of the grinding body and materials. At the same time, different types of liners can be used to adjust the movement state of the grinding body to enhance the abrasive effect of the crushing body on the materials. It is helpful to improve the crushing

contract by Harbin Power Engineering Co. Ltd., to supply 12 MBF coal pulverizers for a new power project in the People's Republic of China.

The industrial output and retail sales is growing at a steady pace driving the growth of Coal Pulverizers systems in the coming years.

Coal dribble or spillage is raw coal that is rejected through the pulverizer's pyrite discharge. This is caused when the velocity across the pulverizer throat is too low to maintain suspension of coal. Air velocities through the pulverizer throat should be 7,000 to 7,500 Fpm when calculated on a free jet basis.

This Code applies to the pulverizing system as a whole, including all the component parts necessary to take the raw coal, hot air and tempering air at the system inlet, and deliver pulverized coal in proper mixture with air and/or flue gas at the desired temperature at the outlet of the system.

Coal continues to be the major fuel for electricity production in the United States, and most of this coal is burned in pulverized coal-fired boilers.

Holmes Coal Pulverizers are bench-type units that perform well in reducing coal or coke from No. 4 to No. 60 sieve size. Models are available with manual or auger feed. All units are constructed of painted steel and cast iron, and have a one-piece balanced rotor with hard coated hammers, driven by 1hp, single-phase motor with overload protection.

Our boiler mills and coal pulverizers span the globe and are built in a variety of sizes and capacities. We provide customized maintenance solutions 

Coal pulverizers are used to dry, grind and classify. Drying is achieved as hot gas passes through the pulverizer and removes moisture from the pulverized coal. The hot gases used should have a low oxygen content, this reduces the likelihood of accidental combustion within the mill.

As the mill rotates, the balls cascade and pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. Properly sized pulverized
