For the hammer crusher, the following is a simple understanding and introduction of it: The hammer crusher has the advantages of large crushing ratio, uniform discharge size, less pulverized material and low energy consumption. However, due to the faster wear of the hammer head, it is limited in the application of hard material crushing; in addition, because the purlin is afraid of clogging, it is not suitable for crushing the material with high humidity and clay . This crusher usually used crushing limestone, shale, coal, gypsum, chalk and other hard brittle materials below. A ring crusher that replaces the hammerhead of a hammer crusher with a steel ring is a variant of the hammer crusher. It uses a combination of high-speed impact and low-speed rolling to break up the material, thus obtaining a finer product, mainly used to break coal for power plants, but also for the crushing of gypsum, salt chemical raw materials and some medium-hard materials.
