The importance of crushing equipment in lime kilns

Crushing equipment is mainly composed of jaw crusher, impact crusher, cone crusher, compound crusher, hammer crusher, roll crusher, and rock crusher etc.
The usage range of crushing equipment is very wide, below as an introduction to the treatment process of crushing equipment in lime kiln. Limestone into the lime rotary kiln system before, the general need to crush, mix, mud and grading and other processes. Some of these processes may be handled at once in the limestone mining process, and the treated limestone raw materials can be processed directly into the lime rotary kiln for further processing. However, some limestone raw materials may need to be transported to the calcination plant after all the above process, for lime rotary kiln production line customers choose front-end equipment, it is necessary to clear the raw materials is not the need for these processes. Usually with qualified material is to enter the lime rotary kiln standard requirements of raw materials, can be directly into the production workshop.
However, in most cases, if the plant limestone crushed stone exceeds the lower limit of particle size, it is necessary to set up screening equipment. In addition, there will be a lot of scrap in the process of transportation, too much waste into the kiln will not be conducive to lime rotary kiln ventilation and kiln control. Unqualified materials into the lime production workshop will need to be broken in the workshop, screening treatment. Limestone material broken generally divided into one or more broken, according to the different particle size of limestone raw materials to choose the appropriate crushing equipment and crushing process. Generally crushing the choice of jaw crusher, screening equipment selection of double-layer screening, the sieve material can be into the lime rotary kiln calcination, sieve above the material should return to continue to break, the screen below cannot participate in the follow-up process.
In practice, the factors that should be taken into account in the selection of crushing equipment are the physical properties of the material, such as friability, viscosity, moisture content and maximum feed size. The total production and machine requirements of the finished product require the type of crushing equipment production capacity; technical and economic indicators, so that both meet the quality, quantity requirements, easy to operate, reliable, and maximize the cost savings.
