To feed a rod and/or ball milling circuit, you need to crush as follow: Crushers for large giant process plants >2,000 to 200,000 TPD using semiautogenous mills only require primary crushing and are selected as well as designed based on: Expected Throughput F80 Top Feed size distributions Desired P80 Product size distributions Feeding method
Raymond mill is often used to process materials with Mohs hardness below and humidity below 6%. The processing fineness is between 80325 mesh. In some cases, the fineness can reach 600 mesh, and the hourly production is more than 150 tons. Advantage. Small size and lightweight, so it is easy to install.
Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than mm is around 78% weight for both crushing mechanisms.
The mill feed ore is sampled after a continuous process of systematic mixing, crushing, grinding, and pulverizing in the beneficiation plant. The fragment sizes have attained a best possible interlining homogeneity and uniformity at (−) 100 mesh size, and are collected by automatic sampler at 15/30 min intervals after ball/rod mills.
diameter and crush 1200 ton/h to a maximum product size of 250 mm. Smaller secondary crushers reduce the particle size of precrushed feed to 6 to 50 mm at much lower rates of throughput.

First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to. The crusher "breaks it and the fine material produced will drop through the gap between the mantle and the liner as it opens. The coarse material that can't fall through will remain to be crushed with the next gyration.

A primary crusher is the one which crushes very large lumps to yield a product 150 to 250 mm in A secondary crusher is the one which takes the product from a primary crusher and reduces it to particles about 6 mm size. Grinders are the machines which reduce crushed feed to powder. An intermediate grinder yield a p that might pass a 40 mesh screen.

There is a basic principle of crushing: don't load into a crusher a ready size. For a SAG mill similarly, but only on the contrary: don't load the pieces which it can't crush. When you load large pieces in a mill, you spend is useless the electric power: large pieces rotate in a mill, but crushing doesn't happen. Large pieces occupy mill volume ...
Most of the highgrade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (− + mm) and fines (approximately − mm) products.
Fig. 2 b shows a large gyratory crusher processing run of mine ore to 100150 mm followed by two stages of cone crushing to generate a P80 of 612 mm which could be fed into a large ball mill operating in closed circuit with hydrocyclones. By using multiple process lines, these circuits could process up to 100,000 tonnes of ore per day.
Rock Crusher History. History tells us, it was in 1830, the first US patent was issued on a rock crushing machine. It covered a device which, in a crude way, incorporated the drop hammer principle later used in the famous stamp mill, whose history is so intimately linked with that of the golden age of mining. In 1840, another patent was issued ...
