摘要：The crushing operation plays a vital role in providing the link between the quarrying ofthe raw materials, i.e. limestone, gypsum, pozzuolana, etc. and the actual cementmanufacturing process. Efficient crushing is a pre-requisite to the trouble-free pro-duction flow within the cement works. The ideal crushing equipment to fulfil this taskshould be able to handle large-size feed material at a high rate and utilise the naturalcleavage planes of the material to effect successful comminution. For many years,HAZEMAG&EPR GmbH has been a market leader in this field, supplying impactcrushers and primary crushing equipment world-wide.
