TECHNICAL GUIDE

Cement plant crushing limestone wear hammer wear characteristics [ 2013-08-27 ]

The level of silicon content in the limestone chemical composition on the hammerhead service life has a direct impact, the higher the silicon content, the shorter the hammer the life of the best-case scenario is less than 2% of silicon content in the limestone. The other hand, limestone compressive strength of high and low and hammer is closely related to life. The higher the compressive strength, fragile worse, the hammer will be a short service life.

Resolve the four factors affecting the hammerhead life [ 2013-08-27 ]

Crusher hammer: hammer crusher hammer composite hammer crusher, sand making machine, hammer, hammer of crushing machine, crusher, hammer, etc., it's life with the following four factors:
