Abstract

PT. X is one of the companies engaged in andesite mining and crushing. Currently, the PT X crusher factory produces 233.3 tons/day of andesite with 2 crusher units, with a demand of 200 - 300 tons/day. The production is expected to be 468.8 tons/day if the third crusher has been built. However, market demand increased to 1100 tons/day. Therefore PT X plans to build a new crusher plant in a new location because the current location is insufficient if added to any other crusher unit. In the construction of a new crusher plant, a crusher plant design is needed to obtain what tools are needed to obtain the desired production target and to determine the setting of the crusher. The problem that occurs is that a new crusher plant design is needed for the production of 800 tons/day on the condition that the product size of -20 + 10 mm is the largest percentage of the whole, more than 28%. In designing a new crusher plant, some data is needed including material size distribution in the stockyard, effective working time, efficiency of each deck screen, and the location of the establishment of a new crusher plant.
