Pulverizers - Weebly
Ball & Tube Mill The oldest pulverizer design still in frequent use. 25% to 30% of cylinder volume is filled with wear resistant balls of 30 – 60mm. The cylinder is rotated at a speed of about 20 rpm. Specific power consumption 22 kWh per Ton. Suitable for hard coals. Highly reliable in requires low maintenance.
A Comparison of Three Types of Coal Pulverizers
ball tube mills and high-speed attrition (ATRITA@ ) pulverizers for use in the pulverization of all available coals, ranging from anthracites to lignites. The most common usage has been in direct-fired coal systems of fossil fueled steam generators. In all, Riley has supplied …
Pulverizer Application for High Volatile High Moisture Coals
Figure 4 compares a conventional vertical table type pulverizer with a ball tube mill pulverizing system with crusher dryer. The table type pulverizer allows high temperature air to reach the coal charge. The ball mill system with crusher dryer normally reduces the inlet temperature to less than the auto ignition point of the coal charge.
