What is a Jaw Crusher? – MEKA Crushing Equipment

In general, crushing is carried out in three stages, depending on the desired size of the material. Primary Crushing. This is the first stage of the crushing process. In general, the size of the feed material, which is between 800 and 1500 mm, is reduced to between 150 and 300 mm. Secondary Crushing. This is the second stage of crushing.

2013-3-6  The crushing strength of concrete is influenced by a number of factors in addition to the water/cement ratio and the degree of compaction. The more important factors are: (1) Type of cement and its quality. Both the rate of strength gain and the ultimate strength may be affected. (2) Type and surface texture of aggregate.
