Abstract

PT Semen Baturaja is one of the largest cement producers in Indonesia, located in South Sumatra. This company produces various types of cement to meet market needs in the Sumatra region and surrounding areas.

A hammer crusher is an important tool in the cement production process, which functions to hit the material so that it is crushed into smaller sizes. Hammer wear and productivity greatly determines the results of the cement production process. The wear that occurs in this hammer crusher is abrasion wear. In terms of hammer crusher productivity from January to July, the highest value was obtained in March, namely 680.05 tons/hour and the lowest productivity value was in February, namely 547.16 tons/hour. Regarding the efficiency of the hammer crusher, it can be seen that the hammer crusher has a very good efficiency value of 81.48%.
