Limestone crushing plant improvement and development trend

Time: 2015-02-04

From ancient times, is the cornerstone of limestone material, and this is no doubt true. Great Wall of China, the pyramids of Egypt, Greece and Rome as well as the building of the Temple, this all examples illustrate the use of limestone humans long ago or its other products. Since 1824 the British invention of Portland cement, but also promote the development of limestone mining industry.

Limestone as a wider distribution of mineral resources in the construction industry has been a lot of applications. However, due to the limestone from mining to processing applications there are numerous dangers and difficulties, which are a serious impediment to the development of a factor limestone. Faced with these problems, we can do is try to develop limestone production equipment, the extensive application of limestone to new heights.

Saving large-scale limestone crusher is the latest breakthrough in limestone processing and improved. Broken development process and broken equipment, but also with mining and mineral processing are closely related. Process used in the cement industry limestone crusher are jaw crusher, cone crusher, impact crusher and hammer crusher and so on, but because of dry cement production of large, broken equipment has undergone great changes, technology simplify and progressively larger energy-saving equipment is the trend

Modern large-scale cement plant limestone crushing generally use large crushing ratio of hammer crusher and impact crusher. From ore mining block of the mine depends on the scale mining, mining methods and structural characteristics of the ore, sometimes up to a maximum size 2m; raw mill feed particle size depends on the mill type and size, usually 25 ~ 30mm, roller mill can Enlarge ~ 1] 5mm ~ 80mm, from the broken ore to the mill particle size reduction ratio of about 40 to 60 in the past two-stage crushing limestone used since the 1970s, foreign high crushing ratio (over 40) of the crusher and achieve a single stage crushing, our development since the 1980s, is now the single rotor and double rotor two types of single stage hammer crusher for large-scale use of various cement plant, noise less than 90dB. Shanghai Zenith developed and large single stage hammer crusher has been widely used in modern large-scale limestone cement production.
