Nowadays cost reduction in every part of a production plant is a major key to surviving in global as well as in regional markets. Therefore, for quarries it is also necessary to review where money can be saved in order to increase profits and face challenging market prices. Considerations regarding applications, mobile crushing systems plays an important role in quarries.
The major operation of mobile crushing plants in quarries, up to and including primary crushing, can be split into drilling, blasting, loading, hauling and finally the primary crushing itself. Within these operations the blasted material is usually transported by dump trucks to the primary crushing stations, which traditionally are stationary plants. Looking back, it has become obvious that often companies have set up the plants at a more or less good starting position not thinking about the further development in the future. In a lot of cases the pit extended itself far away from the preparation plants and more and more haulage needs to be done. This is one of the most important points to be mentioned, because depending on the haulage distance and operational cost structures within the quarry, only the haulage costs themselves represent 30 to 60 percent of the whole operational costs. Therefore in countries with high fuel prices the most interested companies for mobile technology can be found. barite processing plant
In order to lower the haulage costs, there are essentially two ways to achieve this aim. The first solution is to buy bigger dump trucks and the second might be to implement conveyor belts. If you decide for the first solution you have to check if your excavation systems, haul roads, your feed hopper and, if the feed hopper is housed, if the housing fits to the bigger dump trucks. The benefit of this decision is very simple. You can produce the same mass of raw materials with fewer employees, or on the other hand increase the production. If you decide for the second possibility then you have chosen lower operating costs for transportation and in addition to this, in pit crushing as well. In pit crushing is in fact directly linked to the conveying system, because the blasted material, concerning block size, cannot be conveyed without preparation. The key to cost reduction is an in pit crushing system (IPCS), a combination of track mounted mobile crusher, with mobile and fixed conveyor belts. In the following the authors will just refer to the IPCS, due to the fact that this is the only continuous solution known for quarries. These solutions can work as well in other fields of application, e.g. civil engineering, recycling, tunnelling and many more. gold crusher
