the central kalimantan calcium carbonate project indonesia
deep in the heart of borneo island in the central kalimantan province of indonesia a transformative industrial project is bringing modern mineral processing to a region traditionally dominated by forestry and palm oil plantations. this is the central kalimantan calcium carbonate project which features a state-of-the-art stone powder grinding mill designed to process the regions abundant high-purity limestone.
the project centers on a mtw series european trapezium mill supplied by a leading chinese manufacturer with a designed capacity of 6 tons per hour. the raw limestone is extracted from a nearby hillside where geological surveys have confirmed reserves sufficient for decades of operation. the stone is crushed and fed into the grinding mill where it is pulverized to a precise fineness of 150 microns or approximately 100 mesh.
this specific particle size was chosen for its versatility across multiple industries. the primary application for this powder is as a soil conditioner for the regions vast oil palm plantations where acidic peat soils require regular liming to optimize palm oil yields. the fine powder is also supplied to local rubber plantations and to small-scale manufacturers producing animal feed supplements for the poultry industry.
the project faced significant challenges including the remote location with limited road access and the need to operate reliably in a tropical climate with high humidity and rainfall. the solution was to prefabricate major components off-site and transport them via river barges during the dry season. the grinding mill was also equipped with an enclosed material handling system and a powerful baghouse dust collector to prevent airborne dust in the sensitive rainforest environment.
the 6 tons per hour output from this stone powder grinding mill has created new economic opportunities for local communities reducing the need to transport heavy soil conditioners from distant islands and supporting the sustainable intensification of agriculture in central kalimantan.
