Ball Tube Mill Overview

Ball Tube mills are mostly used in the metallurgical, mining and cement industries. The grain size of the material depends on the number of balls and the quantity of added water. The grinding drum, which revolves around its horizontal axis, is lined with chilled-cast iron plates. Charged with the grinding stock, it is very heavy.

Ball Tube Mill Features and Benefits :

• Well suited to handle high moisture coals. Minimum wear components that require replacement

• Lower maintenance cost vs any other type pulverizer. Each unit includes two feeders & two crusher dryers

• Components are oversized so that the feeder and crusher dryer at one end can maintain full mill load if the feeder and crusher dryer at the other end are out of service. Two stage pulverization - primary crushing and drying is accomplished in the crusher-dryer

• Lower power consumption than competitor’s Ball Tube Mill. Impervious to tramp metal

• No need for spare mills.

Ball Tube Mill System :

Ball Tube Mill consists of a rotating tube filled with cast alloy balls. Raw materiales is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the materiales, crushing and pulverizing it .

The SBM Ball Tube Mill (BTM) is a cylindrical low-speed grinding mill. As one of the most robust mills, it consists of a steel barrel, lined with cast abrasion resistant liners, and partially filled with hardened steel balls. Coal mixed with preheated primary air enters both ends of the mill from a crusher/dryer or feeder. As the mill rotates, the balls cascade and pulverize the coal by impact and attrition. The pulverized coal is then conveyed by primary air to external centrifugal classifiers. Fine coal particles exit the classifier into coal piping for transport to the furnace, while oversized coal particles return to the mill, by classification, for further pulverizing.

A ball tube mill may be described as a cylinder made of steel plate having separate heads or trunion attached to the ends with the trunion resting on suitale bearings for supporting the machine. The trunion are hollow to allow for the introduction of discharge of the materials undergoing reduction in size. The mill shell is lined with chilled iron,carbon steel, manganese steel, high chrome liners attached to shell body with connter sunk bolts. These liners are made in different shapes so that the counter inside surface of the mill is suited for requirement of application.
