Cone crusher routine maintenance 1, to full production, there would be too coarse granularity. 2, the production line of crushing ratio allocation should be reasonable, so as to maximize the efficiency of the crusher. 3, to have iron removal devices to prevent excessive iron crushing chamber, if the iron is too frequent, it may cause the broken shaft accident. 4, the spring pressure is not too tight, too much pressure will be off-axis incident occurred, the pressure is too small springs frequently beating, impact crusher work, and product size thicker. Roll crusher also called on the roll crusher jaw crusher price, double roll crusher, roll crusher, is the use of the roller surface friction material will be broken into bite, so bear squeeze or split cracked and broken machinery. Roll crusher usually divided by the number of roller single roll, double roll and multi-roll crusher jaw crusher is mainly applicable to crude price jaw crusher mining, metallurgy, chemical, mining and other industries brittle bulk materials, Intermediate crushing, feed their large size, the expected size adjustable, compressive strength of the material ≤160MPa crushing. Especially in the coal industry, the use of the raw coal crusher, long after iron removal, cleaning, no addition to the waste rock, can be directly broken, broken out of the materials jaw crusher effect, uniform size, broken too low, thus simplifying coal preparation process, reducing investment and production costs.
