More Details Ball Mill For Sale Ball Mill Working Principle,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. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either

Chilean Mill - Mineral Processing & Metallurgy

When Barba wrote in 1639 there were three amalgamation machines in use in Peru, the mortar (used in the Tintin process), the trapiche or Chilian mill, and the maray. The mortar was hollowed out in a hard stone, the cavity being about 9 inches both in diameter and in depth. The ore was triturated with water and mercury in this mortar with the aid of an iron pestle, while a stream of water, flowing through,Antapaccay Copper Mine - Mining Technology | Mining,The gearless drive system of the 40ft SAG mill has a power rating of 24MW and the two 26ft ball mills have a power rating of 16.4MW each.
