Abstract


PT Solusi Bangun Andalas Tbk is a company engaged in cement production. Cement production does not only depend on the combustion operation in the rotary kiln but is also determined by the initial heating that occurs in the suspension preheater. The suspension preheater at PT Solusi Bangun Andalas Tbk is composed of four cyclones coated with castable. For the continuity of production, it is necessary to evaluate cyclone performance, problems in operation, influencing factors, and maintenance. The method used in this study is direct observation, interviews, and data in the form of documents, references, and routine reports. Based on the initial inspection, it was found that the castable damage was quite severe on Cyclone 4A, requiring repair. The process of separating raw materials from suspended streams in hot gas occurs due to the centrifugal force experienced by the raw materials so that the raw material particles tend to be thrown against the cyclone wall. Repairs carried out included: Installation of Scaffolding, Cleaning of Damaged Castables, Making Access to Castings, Welding Anchors, Installing Silica Boards, Installing Moldings, and Casting.
