Demolishing a Building: How It Works | BigRentz
As gravity pulls on the ball, its highest point of velocity is achieved at the bottom point of the pendulum arc. Thus, the weight is released from a higher point to create greater velocity. While wrecking ball demolitions are relatively inexpensive and quick, this method causes a lot of debris, dust, and safety hazards.

Getting reaming right | Cutting Tool Engineering
The surface finish obtainable when reaming generally depends on the workpiece material. The range for cast iron is 50 to 80 rms and 30 to 60 rms for steels, and a PCD reamer can impart a finish as fine as 8 rms in aluminum, according to Bysterbusch. Sometimes a hole is bored prior to reaming, but that's not mandatory.

Guide for angled and curved drilling - Bowling, Roy E.
By tipping the guide tube 60a about the curved mid-section 61, the ball mill can be guided in any desired direction. Thus, as the ball mill approaches the floor plate 30, having cut through the baseboard 28 and wall 29, the ball mill can be tipped as shown in FIG. 13 to cut a groove upwardly through the floor plate.

Mar 10, 2022Fishing for parted wireline with a spear is a dangerous operation and should only be performed by a fisherman experienced in this procedure. This is because the wireline can easily ball up so badly that it can cause the hole to be junked. To avoid balling up the wireline, do not attempt to catch the wireline very far below the anticipated top ...

Ball mill - Wikipedia
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
