Sinoma International Engineering Co., Ltd, as general contractor for the new 10 000 tpd cement plant, has contracted HAZEMAG & EPR GmbH to supply a crushing plant.
PT Cemindo Gemilang will receive the following from Hazemag: a large apron feeder, a wobbler feeder for pre-screening and an impact crusher with rotor diameter of 2.5 m and rotor width of 3.0 m. This is the largest impact crusher in the Hazemag product range. A second, small apron feeder will enable the plant to process two different raw materials at the same time.
In addition to the main component of limestone, two different types of clay are crushed. All three materials have been previously tested in detail in the Hazemag pilot plant. On the basis of this investigation, the system concept was determined. The mixture of limestone and clay definitely requires the use of a wobbler, which screens out the fine fractions of the materials before the crusher. In order to perform the screening in an effective way, the wobbler was carried out in three stages, as it comes at every stage to a tumbling of the material and detachment of fines.
Due to the very compact appearance of the limestone with large feed sizes, it was decided to use a heavy impact crusher, wherein the maximum of impact energy can be used for the crushing process. Thus, a high degree of size reduction is achieved. The crusher is, of course, equipped with the well-known, robust GSK-rotor and the proven hydraulic impact apron support system HAZtronic®, which allows easy adjustment of the impact aprons and provides a very high level of operational safety. The total plant capacity is 2500 tph. This makes the installation one of the most powerful crushing plants in the global cement industry.
Delivery of the plant is scheduled for the end of 2014.
