Coallus is a fine-grade coal dust product derived from processed anthracite coal, specifically formulated for use in ferro-casting mold applications. The material is ground to a consistent mesh size to ensure uniform dispersion in foundry sand mixtures. The product's defining characteristic is its low sulfur content, measured at below 1%, making it suitable for ductile iron casting where sulfur-induced defects must be minimized.
The coal dust is produced from aged anthracite, which naturally contains lower volatile matter and higher fixed carbon than bituminous coals. This results in a cleaner burn profile and reduced gas evolution during metal pouring. Typical particle size distribution ranges between 100 and 200 mesh, with less than 3% moisture content. These properties align with industry standards for foundry additives used in high-integrity castings, particularly where surface finish and dimensional accuracy are critical.
This product is primarily purchased by foundries producing ductile iron castings for automotive, pipe, and heavy machinery components. Buyers typically order in full metric ton quantities, with packaging in 25kg polypropylene bags or bulk flexitanks. The supplier states a minimum order of one ton, and delivery is arranged from Jakarta port. Incoterms and lead time are not specified and must be confirmed directly with the supplier.

Before ordering, verify the exact particle size distribution and sulfur content for each batch. Request a certificate of analysis showing sieve results and sulfur measurement via ASTM D4239. Confirm that the material is free from clay, silica, or organic binders, as these can interfere with casting quality. Do not accept material without batch-specific documentation, even if labeled as Coallus.
Lead time, Incoterms, and payment terms are not specified. Buyers must confirm whether the product is shipped FOB Jakarta, CIF destination, or EXW. Payment is typically via T/T in advance for first orders. Request written confirmation of delivery schedule and packaging details, including bag weight, number of bags per pallet, and container loading plan to avoid customs delays.
Upon receipt, inspect bags for moisture damage, clumping, or foreign material. Perform a moisture test using ASTM D2216 and a sieve analysis to verify particle size. Retain a sample from each batch for future quality audits. If used in critical castings, consider third-party inspection before production. Ensure the supplier provides a traceable batch number linked to the analysis report.
