Indonesia's industrial mineral power mill plant from china
on the island of belitung indonesia known for its white sand beaches and tin mining history a new industry is emerging centered around the processing of local granite and andesite. a high-pressure suspension grinding mill with a capacity of 8 tons per hour is the centerpiece of this operation. it grinds the hard volcanic rock down to a specific fineness of 300 microns. this coarse yet consistent powder is not for construction in the traditional sense but is destined for use as a high-quality base material for roads and a raw material in the production of asphalt.
the andesite rock is incredibly hard and durable making it ideal for applications requiring high wear resistance. the grinding mill uses a unique principle where high-pressure springs exert tremendous force on the grinding rollers allowing them to crush the extremely hard material efficiently. the 300 micron output is a carefully chosen specification.
it is coarse enough to provide structural strength as a road base but fine enough to bind perfectly with bitumen in asphalt mixes. this processed material is shipped to infrastructure projects across the archipelago including the new capital city in kalimantan. by utilizing local stone and processing it with this 8 ton per hour mill indonesia is reducing its reliance on imported construction materials and building its future on a foundation of its own natural resources.
