The secondary crusher housing is a rugged, fabricated steel plate construction with heavy external bracing for increased strength and stability. For quick and easy inspection of the internal wear parts, the housing is fitted with large doors which are opened and secured by a special mechanism.
The crushed ore is then moved by conveyor to the secondary crushing stage. A cone crusher is used here. The ore goes into the cone crusher's feeding system, which usually has a hopper and a feed distributor. ... A 15% overload on the crusher might result in a 5–10% reduction in capacity and accelerate the wear and tear of the liners …
The average input size for a secondary crusher ranges from 13" to 4" during this stage. Secondary crushing is especially important for making graded material that is going on to be used on government projects. ... ratio, it thus creates more finished product. This results in less reduction needed down the process and thus may result in fines ...
In most applications, the secondary crusher has a primary target of maximizing the reduction ratio and reducing the top size and F80 for the downstream equipment. However, in some applications, the target can …
Most secondary crushers are cone crushers or horizontal-shaft impact crushers. Tertiary and quaternary crushers are usually cone crushers, although some applications can call for vertical-shaft impact …
The chemical composition of both products is very similar. The content of silica is lower in the fine fractions, while the content of CaO + LOI is higher, indicating a preferential concentration of cement paste in the finer fraction and natural aggregates in the coarser fractions.The results between the jaw and impact crusher differ only slightly, …
