Raymond mill, or raymond grinder is a kind of grinding machine which is widely used to grind non-flammable and non-explosive materials like barite, calcite, potash feldspar, dolomite, gypsum, talcum, mica, marble, limestone, kaolin, clay, coal etc. The raw materials should be below scale 7 Moth’s hardness. The fineness of the finished product can be adjusted from 100 to 425 mesh (35micron) according to requirements.
In the Raymond grinding plant, the stuff for grinding is loaded into the grinding chamber of the main frame evenly and continuously. The stuff is grinded when roller rolls. The rough powder will be put back to grinder for regrinding. The fine powder flows into the product cyclone collector together with airflow and is expelled from the powder output pipe as product.
Marampa Haematite Iron Ore Mine
The Marampa mine is a brownfield haematite iron ore mine located approximately 150km north-east of Freetown in Sierra Leone, West Africa.
During the mining and processing process, a two-phase high intensity magnetic separation process will result in 65.5% iron with 2.5% SiO2 and 2.9% Al2O3 from approximately 3t of tailings.
Raymond mill is widely used in the iron ore milling circuit to grind the crushed iron ore. The coarse grinding mill can handle with bulk iron ore minerals and grind the iron ore down to 1mm.

Porgera Gold Mine
The Porgera gold mine is located in Enga Province, about 600km north west of Port Moresby in Papua New Guinea.
Low-grade stockpile and open pit ore are crushed using a gyratory crusher. Coarse ore is conveyed from the stockpile to two parallel SAG mills. The discharge is pumped to three clusters of cyclones in closed circuit with three raymond mills. Coarse SAG mill discharge is crushed in two cone crushers and returned to the SAG feed. The slurry is then pumped to the flotation circuit.
