SBM Coal Pulverizer

Coal pulverization is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.

SBM Machinery is a specialist manufacturer of Coal pulverizer plant. It supplies a variety crusher equipments and also design complete pair of Coal pulverizer plant in line with the requirements of consumers. Our Coal pulverizer plant have exported to numerous countries around the world.

There are several pieces of equipment involved in processing coal to be burned in this fashion. Top figure is a simplified diagram detailing this equipment in a direct-fired coal burning system. Raw coal is fed through a central coal inlet at the top of the pulverizer and falls by gravity to the rotating grinding table, mixing with classifier rejects returned for re-grinding. Centrifugal action forces the coal outward to the grinding ring where it is pulverized between the ring and three grinding rollers.

SBM Machinery are major manufacturers of coal pulverizing equipment. The four most common types of coal pulverizers are:

1. Ball-Tube Mill Pulverizers
This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it.

2. Impact Mill Pulverizers
Grinding Action is carried out by a series of hinged or fixed hammers revolving in an enclosed chamber with wear resistant plates. The hammers impact on the coal, crushing it against the plates. Further pulverization is achieved as the smaller coal particles are ground through attrition against each other and the grinding face.

3. Vertical Roller Mill Pulverizers
This mill uses hydraulically loaded vertical rollers resembling large tires to pulverize raw coal fed down onto a rotating table. As the table rotates, the raw coal is pulverized as it passes underneath the rollers. Hot air forced through the bottom of the pulverizing chamber removes unwanted moisture and transports the pulverized coal dust up through the top of the pulverizer and out the exhaust pipes directly to the burner. The more recent coal pulverizer designs are Vertical Roller Mills.

4. Ring-Roll and Ball-Race Mill Pulverizers
A ball or roller between two races or rings provides the grinding surfaces on which pulverization occurs. One or both of the races may rotate against a ball or roll. Ring-Roll and Ball-Race Mills comprise the majority of coal pulverizers currently in service at power generating facilities.
