METHOD AND APPARATUS FOR DETACHING

During the periods when the tube mill is not is use, the charge within the grinding pipe can consolidate and become firmly stuck to the inner wall of the grinding pipe, this is referred to as "frozen charge". When the tube mill is set in motion again after a period of non-use during which frozen charge has occurred, there is a high likelihood that the frozen charge may become detached at the highest point of

Dropped charge, also known as frozen or locked charge, occurs when solidified material inside a horizontal grinding mill does not cascade when the mill starts rotating at start up. Instead, it is lifted and then free falls onto the mill shell. Dropped charges experienced in large ball mills can be heard and felt hundreds of meters away and can be confused with an explosion or earthquake on

Zen and the Art of Dislodging Frozen Charge in a

The technology at issue was, as noted in the title, a method of operation of a tube or pipe mill to dislodge frozen charge in a safe/efficient manner. The dislodging of frozen charge at too high a point in rotation of the mill can cause the mill to crash to bottom causing damage and the mill can be driven in a manner to dislodge the charge at a lower point. The broadest claim read as follows:

The 14MW SAG mill at Tarkwa, Ghana, experienced a frozen drop charge incident on 10 February 2010. This caused downtime of 112 hours, a repair cost of $200k and production loss of 162,000 tons, corresponding to a loss of $8.9M. A new locked charge protection system was installed on the two Tarkwa mills on 30 July 2010, mitigating this risk. This system calculates the ore angle in real time
