What is the first step, before you choose the machinery for the cement industry?

　　The very first step should always be an analysis of the career, and in particular characteristics of the raw materials. Of Prime importance is the hardness of the material which you want to crush. For a description of these properties compression strength, Los Angeles index or hardness Mohs should be identified and the test load should be carried out.

　　What crusher best for grinding of cement?

　　Characteristics of raw materials for cement production differ in a wide range. Limestone deposits, which are used today as a basic materials, show very different properties in respect of hardness, abrasiveness and stickiness. For optimization of the process of crushing, as well as the investment and operating costs, there are various types of crushers.

　　Whether silica influence the selection of the crushers?

　　Silica is an important issue for consideration before using crushers for the cement industry. Due to the high velocity of the rotor, the suppression of instruments are subject to wear. Before making a final decision, abrasive raw materials need to be analysed carefully, in order not to suffer from high maintenance costs. If the content of silica of the above-mentioned values of crushing systems with a small difference in speed between the material for crushing and grinding tools must be used.

　　As the best choose the type and characteristics of the cement equipment?

　　When choosing equipment, types and specifications should pay attention to the data:

　　1. Equipment type and specification to meet the requirements of the productive capacity and adaptation of technological conditions, the conditions of work.

　　2. Coefficient of efficiency of the equipment. Coefficient of efficiency of the equipment consists of a number of technical parameters. In the selection of equipment, the efficiency of the equipment it is necessary to adapt its parameter production technology.

　　3. The reliability of the equipment. The equipment can not only produce high quality products, but also has a low failure rate. Reliable operation and stable qualified products also an important issue.

　　4. Low energy consumption and high energy saving equipment.

　　5. Safety and environmental protection. Safe and reliable equipment without the pollution of the environment is useful for the implementation of environmentally friendly products.

　　6. Set of equipment suits all device one or affiliated companies.

　　7. Maintainability. Good maintainability requires simple structure, rational combination of the parts of the equipment, a high degree of standardization, etc..

　　8. Service life of the equipment (strength). In the premises of product quality, long service life is important.

　　9. In the first purchase of equipment investment, reasonable price of the equipment should not merely be considered persecution "of cheap equipment".
