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. Less abrasive and softer rocks or stones ...

Both crushing and grinding require energy to reduce the ore size. However, in grinding operations we consume much more eneregy than crushing, up to 100 times ( thousands of kw compared to tens in crushing). Because as far as we go to finer size we need more force and collosions for further size reduction. In fact grinding is the most consume energy section for the whole processing plant, up to ...

Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing

These crush the ore to less than 150 millimetres, which is a suitable size to serve as feed for the secondary crushing stage. In this stage, the ore is crushed in cone crushers to less than 10 to 15 millimetres. This material is the feed for the grinding mill.

For most free-milling ores, a pretreatment process is necessary when chemical recovery is being employed. The gold is not sufficiently liberated as is the case with placer ores, and therefore crushing and grinding is required to allow the cyanide to access gold components.

For example, hard rocks that come from blasting can be big as 1m in size, and require multiple stages of crushing and grinding. In addition, if the valuable mineral is finely disseminated in the ore the grinding size can be down to 40 microns, which can be achieved by two grinding stages at least.

Crushing installations usually are operated to produce the required mill tonnage at a specified size distribution under conditions of varying ore hardness by the variation of the number of operating hours per day. It is normal practice to generously size a small crushing plant so that the daily design crushing tonnage can be produced in one, or at most two, operating shifts per working day.

2021-03-03 The main advantage is that the process does not require any vibrating screens, which have proven to be very high-maintenance and can produce a large volume of rejects in winter (up to 5% of the ore feed). During wet crushing, the gap between each set of sizer rollers are progressively smaller, allowing for better break-down of any chunks of oil sands. The process therefore produces no rejects ...
