Batch Extractor System Repair Returns Material Raw Meal Sampler- Raw meal sampler is a tool that serves to pick up raw meal material and send to Poly AQC (Polysius Laborat Automatic Quality Control) by utilizing pneumatic power. Sampler takes material from 391-AS5 water slide to know the quality and chemical composition of raw material material after heating, crushing, separating and transporting from raw mill. The sampler consists of a stirring machine to homogenize raw meal material, scrapers to feed raw material material into capsules, raw material feeding capsule sending to AQC Poly in laboratory, and a batch extractor which serves to return material to a 391-BE1 bucket elevator. Return of material in batch extractor through hose channel, while hose batch extractor made from rubber material and problems that arise is leakage at hose. Leakage in the hose is caused by life time and environmental influences. The effect of leakage is a material spill which results in buildup, ie dust. The effect of dust will cause saturation on the compressor filter so that the compressor gets hot. To overcome the above problems then the solution is to make improvements by replacing the original channel from the hose into a pipe with the consideration that the vibration around the channel back low so as to enable the replacement of hose into a pipe. The pipe used is galvanized because it is cheap, powerful, and easy to use. This pipe is connected with union help so it can be easier when care and replacement. After replacing the back channel from the hose to the galvanized pipe can save the cost of Rp 6,816,800, - and the chance of leakage is small so as to make the raw raw sampler area clean from the pile of material and the compressor is safe.
