Most will also have a hole or depression in the center, and will be small, generally less than a centimeter in diameter. They will be bead-like if separated from the rock they are found in. In contrast, bryozoans with circular cross sections will be tubular, and horn corals will often be conical or cup-shaped.
How to Identify Black Minerals - ThoughtCo
Hornblende. Hornblende is the typical amphibole mineral in igneous and metamorphic rocks. Look for glossy black or dark green crystals and cleavage fragments forming flattened prisms in cross-section (corner angles of 56 and 124 degrees). Crystals may be short or long, and even needle-like in amphibolite schists.
Ball Mills - an overview | ScienceDirect Topics
Conical ball mill. For emptying, the conical mill is installed with a slope from bearing to one. In wet grinding, emptying is realized by the decantation principle, that is, by means of unloading through one of two trunnions. With dry grinding, these mills often work in a closed cycle.

So You Found a Shiny Black Rock: 6 Things it Might Be
However, these rocks always have that red streak on them. When made into powder, the color of the powder is red, which is why it's also called "haimatitē", meaning blood-like. Like other crystals, it's also believed to have healing powers. Those who practice alternative healing use this rock for healing broken bones, insomnia and stress.

Hardinge Conical Mill - Grinding Efficiency Compared
The above remarks relative to the conical pebble-mill also apply to the conical ball-mill, which is similar in all respects to the pebble-mill except that instead of using flint lining and pebbles, steel lining and balls are used to do the crushing. The latter is now coming into use in the place of stamps as a more economical device.

Rock Breaking by Conical Pick Assisted with High Pressure ...
In the process of hard rock breaking, the conical pick bears great cutting force and wear, and the cutting efficiency is lower. Thus different combination ways of water jet and conical pick were proposed to solve this issue; for instance, water jet placed in the front of pick (JFP) and water jet through the center of pick (JCP) was researched by numerical simulation …
