Sinar Tambang Arthalestariis 8,876 tons/day, in fact, in October only reached 319 tons/hour or about 4,309 tons/day is only half of the planned. Thus the need for additional feeding as much as 340 tons/hour or additional material 17 times per hour by dump truck, so that it will achieve the planned production targets. Due to the high water content of the limestone from the front of mining will often make the crusher blocked, this is one of the barriers that lead to failure to achieve the production target of PT.Sinar Tambang Arthalestari, so as to reduce those barriers should also be done blending materials upon dump truck dumping hopper with a ratio of 1:1:1:1for each mining front isSawanganWest, SawanganEast, UndipAbove, and UndipDown to get the water content that relatively lower or about 7% so that increase the production of limestones of 319 tons/hour to 340 tons/hour.
