subject: How To Choose The Most Suitable Production Line [print this page] Generally speaking, because of the low hardness, the limestone belongs to the material which is easy to crush. Therefore, compare to the pebbles, river pebbles, iron ore, steel slag and other materials, the production cost of limestone crushing production line is relatively much lower.
In this case, most of the stone quarries directly use the jaw crusher and impact crusher to configurate the limestone crushing production line. After crushing, filter out the required stones granularity, which not only gets a good stone grain type, but also saves the cost, prolongs the service life of the equipments.
However, using the impact crusher to crush the limestone has a feature: more powder. This is due to the property of limestone -- relatively easy to broken, and the crushing principle of impact crusher is impact crushing, which leads to the inevitability of more powder. But too much powder can be used in cement production, so using the impact crusher as the secondary crusher is ideal for cement companies to extend the industrial chain to enter the gravel market. And the development of co-production of limestone can greatly increase the comprehensive benefits.
If the customer has a low requirement for the particle size of stone, we can use the way of two-stage jaw-crushing to reduce the proportion of powder, at the same time, reduce the investment cost relatively. Notes: The selection of specific process should be determined depending on the actual situation of customers.
For the limestone with large silicon content, it is not easy to crush relatively, so the crushing cost will be in a corresponding increase. Especially for the cost of the attrition of the hammer of crusher, the attrition of the hammer is extremely serious. Some stone quarry must change the hammer in one day, or even less than one day. In this case, the abrasion resistance of the wear parts of hammer crusher is extremely important. Choose a high quality and wearable hammer not only means the cost saving, but also means the high efficiency.
