23/11/2013· Ball and Race Beater Mill mill or Fan Mill. 11. TYPES OF MILL • Tube or ball mills: These are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. • Vertical spindle mill: These are medium-speed machines that include bowl mills, ring roll mills, and ring and ball mills. The bowl mills are further
13/12/2011· Ball mills are always preferred to be operated at full capacity because the power consumption of this type of mill is very high at lower loads when compared with other types. Ball mills can be designed for a very high capacity like 75 tons per hour output for a specific coal.

Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types- attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.
INTRODUCTION TO BOWL MILLS: Coal is the one of the most dominating energy source because of its cost, availability and transportability. Pulverized form of coal has made modern steam generating units highly thermal efficient, reliable, safe and able to efficiently use of low-grade coals. It provides coal-air fuel control, flame stability

Mainly there are three types of pulverizer used in industry: the slow speed mills like ball tube mills, the medium speed mills like bowl, ball and race, roller mills fall in this category, and the third type is the high speed impact mill. The slow speed and medium speed mills are selected for coals ranging from sub-bituminous to anthracite. The
The ball and tube mills are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. Due to its shape, it is called a tube mill and due to use of grinding balls for crushing, it is called a ball mill, or both terms as a ball tube mill. These mills are also designated as

5. CONCLUSION The hierarchical and predictive fuzzy control algorithm proposed in this paper for the ball mill of the central storage pulverizing system of thermal power plant not only overcomes the difficulty of strong coupling between multi-variables in automatic control system, but also enhances the economy due to energy saving. The actual
Ring-Roll and Ball-Race Mills 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 (in a Ring-Roll Mill the rolls may rotate while the ring is stationary). Ring-Roll (Bowl-Mill) and Ball-Race Mills comprise the majority of coal pulverizers currently in service at power generating
B&W's pulverizers, found at power stations throughout the world. From our original E/EL ball-and-race type pulverizers for lower capacity applications, to the latest B&W Roll Wheel™ pulverizer capable of grinding up to 230,000 pounds of coal per hour (104,300 kg/hr), we set the standard for high availability, reliability and low maintenance.
