The characteristics of raw materials required for the cement production differ at a wide range. The limestone deposits used as base material today, show very different properties regarding hardness, abrasiveness and stickiness. To optimize the crushing process as well as the investment and operating costs, different types of crushers are available. To make a proper selection, several important points should be considered in advance. The very first step should always be an analysis of the quarry, and especially the characteristics of the raw material. Of prime importance is the hardness of the material to be crushed. To describe this property the compressive strength, the Los Angeles Index or the Mohs Hardness should be determined and a point load test should be carried out. Recently, several mobile crushing plants made by Hongxing Mining Machinery are successfully sent to Sri Lanka.

This is not the first time for the export of crushing equipment, but this large-scale export of mobile crushing equipment fully proved mining machinery manufacturing technology of Mining Machinery has been recognized by international customers. This is a show of the strength of Hongxing Mining Machinery and it makes the domestic technical development of machinery industry once again proven. After a long investigation and practice, Henan Hongxing Mining Machinery has developed and launched the efficient and environmentally friendly construction waste disposal equipment mobile crushing station. In modern society, nothing can do without mechanical equipment. As a developing country with a vast territory and a large amount of population, housing and transportation become one of the most important issues. However, at present, the housing and transportation in China cannot meet the demand of people and the development of society. Therefore, Chinese government vigorously develops construction industry to meet the demand of people, and then develop the economy to meet the demand of society. The abrasiveness of the material has to be described by its Silica and quartz content, as well as the abrasion index free.
