Steel. Cell phone antennas are bigger and heavier than they look from the ground. Its not uncommon to have 3 sectors x 3 layers = 9 antennas, each maybe 150 cm tall and weighing up to 80 kg. They basically act like sails. The construction has to
These ball materials are often used because they are inexpensive. Nylon is one of the most common plastic ball materials. It is hard, it is tough and it is dense enough so that it sinks in water. Nylon is slightly hygroscopic, so it isn''t the best plastic to be used in water applications. PTFE. is a fairly common plastic ball material.
Ball mills are used in chemistry and in industry to grind hard solids to a very fine powder. They are very similar to rock tumblers. Basically, the idea is to rotate a container filled with heavy metal balls that crush the substance that you want to grind. Ball mills can be used to grind ceramic material, crystalline compounds, and even some metals.
Ball mill is a machine, which usually has a cylindrical tank, in which some marbles are placed that when they collide with the material that is mixed with them for milling; crash it and destroy it. The marbles that are used can be made of steel, stainless steel, rubber ceramics or other materials.
