cement - cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.

The Vertimill product line features standard mill sizes from 11kW (15hp) to 3352kW (4,500hp) and can handle feed sizes up to 6mm …

The Cannington process plant has a demonstrated throughput capacity of 3.4 Mtpa. The ore treatment process at Cannington uses primary underground and surface crushing. Primary grinding and a preliminary talc pre-flotation step follow this. The AG mill operates in closed circuit with a pebble crushing circuit and primary hydrocyclones.

Primary crushing – closed circuit secondary crushing – closed circuit HPGR – rougher magnetic separation – ball milling – first cleaner magnetic separation – tertiary milling using stirred mills – second cleaner magnetic separation. In Option 3, secondary crushing and HPGR effectively replace AG milling with pebble crushing.

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG ...

Comminution test work at Metso also allowed the design of an optimized milling circuit for the oxide phase, which will employ only one rod mill for grinding with a …

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
