HPGR or highpressure grinding rolls have made broad advances into nonferrous metal mining The technology is now widely viewed as a primary milling alternative and there arc a number of large installations commissioned in recent years After these developments an HPGR based circuit configuration would often be the base case for certain ore types such as very hard abrasive ores
Our products sell well all over the world,and have advanced technology in the field of crushing sand grinding powder.
High frequency screen is also called high frequency vibrating screen, which is a kind of separating equipment in ore dressing plants. It separates materials according to their particle sizes.
High efficiency concentrator is suitable for dewatering treatment of concentrate and tailings on ore dressing plants, which can increase the 20-30% slurry to about 40-70%.
Calcium carbonate is the main raw material to make cement, lime and calcium carbide, and it is an indispensable flux limestone in metallurgical industry.
Fine crusher is also known as tertiary crusher, which is widely used for the fine crushing of granite, basalt, limestone, pebble, cement clinker, quartz, iron ore, bauxite and other minerals.
Basalt and diabase have higher hardness and silicon content, which belong to materials that are hard to crush in actual crushing operations or have higher crushing costs. More generally, basalt and diabase are hard and tough materials.
Mobile impact crusher or portable impact crusher adopts the latest manufacturing technology, which uses high-quality chromium plate hammer and wear-resisting lining.
