For the effective crushing of ores, you should choose construction waste crusher according to the characteristics of the ores. They are different in compressive, abrasion resistance and humidity, so their requirements of the crusher equipment are not the same.
When the compressive strength of the ore is relatively weak, such as soft shale, rock salt, gypsum, chalk, anthracite, common marl, sandstone, conglomerate, broken cement stone soil and broken shale, it is not necessary to use the jaw crusher. Hammer crusher, roller crusher, impact crusher, cone crusher and composite crusher are available.
There are some medium hard ore, such as clay rock, limestone, sandstone and unstable density marl. Such kind of ores can use jaw crusher, hammer crusher, as well as roll crusher, counterattack crusher and hammer crusher, which has a wide optional range.
And for the solid, delicate and tough ores, such as quartzite, basalt, granitic rocks, quartz porphyry, sandstone, limestone, iron ore, quartz vein, conglomerate, magnesium ore, marble, dolomite, pyrite, siliceous shale, sandstone and shale. The crushing machine with strong crushing ability should be used to crush such kind of hard materials, for example, jaw crusher. If other crusher are used, it will cause great damage to the equipment.
From the water content of ore, if the humidity of the material is too large, the ores cannot be crushed by hammer crusher with grate for discharging materials, such as clay mixture. For the brittle ore, it is not suitable for the grinding type crusher. Otherwise the grinding process will products too much fine powder, this kind of ore should adopt impact crusher.
