Abstract:
Crushing plant is one of the processing unit that consist of many tools which continue cycle and it aims to reduce small materials, that process is the beginning step and most important things of comminution process. Peformence Analysis of Crushing Plan A with heavy equipment productivity which some actual fact are aims to know between work peformence of heavy equipment with production target. Productivity of crushing plan can be worse when some troble in crushing plan are happen at a time, the biggest impact of that trouble is The production does not according with target planned. For example, company set target production at 5805 ton/day but the actual fact just 5506,312 ton/day. The result calculation at Primary Crushing step: Mechanical Avability (MA)= 98,21 %, Physical Avability (PA) = 82,32 %, Use of Avability (UA)= 82,06%, Effective of Utilization (EU)= 80,85%, Production rate Index (PRI)= 89,335%,Overal Equipment Effectiveness (OEE)= 87,736 %. The result calculation at Secondary Crushing step: Mechanical Avability (MA)= 98,33%, Physical Avability (PA) = 80,92%, Use of Avability (UA)= 98,64%, Effective of Utilization (EU)= 80,85%, Production rate Index (PRI)= 88,206%,Overal Equipment Effectiveness (OEE)= 86,88%. The result Calculation at Tertiery Crushing step: Mechanical Avability (MA)= 98,33%, Physical Avability (PA) = 80,92%, Use of Avability (UA)= 98,64%, Effective of Utilization (EU)= 80,85%, Production rate Index (PRI)= 79,315%,Overal Equipment Effectiveness (OEE)= 80,52%.
