Mineral Crushing Machines

The minerals and ores we process most often fall into two practical categories for crusher selection: softer, less abrasive material like alumina hydrate, borax, sodium silicate, and magnesite, and harder, more abrasive material like iron ore, chrome ore, fluorspar ore, and tungsten ore. Softer minerals generally run well through our cage mills and pulverizers, which use selective impact across multiple rows to hit a fine, controlled particle size without excess wear. Harder, more abrasive ores put more stress on wear parts, which is why our horizontal shaft impactors and vertical shaft impactor are built with replaceable wear components suited to sustained abrasive duty. If you're processing a mineral not listed here, from bauxite and feldspar to trona ore and vermiculite ore, we can tell you which crusher type fits based on hardness, moisture content, and your target output size.

We manufacture three core equipment types for mineral and ore crushing, each suited to a different combination of material hardness, feed size, and finished product requirement.

• Horizontal Shaft Impactors for Primary and Secondary Reduction: Our Mega Slam HSI is our horizontal shaft impactor built for high-capacity primary reduction, and our Grand Slam HSI is our secondary impact crusher built to handle a wide range of materials in a smaller footprint. Both use horizontal shaft impact to strike material rather than compress it, which works well across the range of ores and minerals we process, from bauxite to barite ore.
• Vertical Shaft Impactor for Coarse-to-Fine Crushing: Our V-Slam Impactor VSI handles coarse-to-fine reduction using a vertical shaft design, which gives us a different impact geometry than our horizontal shaft machines. We use the V-Slam when a mineral or ore needs to move from a coarser feed size down to a finer product in fewer stages than a horizontal impactor would require.
• Cage Mills and Pulverizers for Fine, Controlled Particle Size: Our cage mills and pulverizers use multiple rows of spinning cages to reduce minerals through selective impact, producing a controlled fine particle size on materials like gypsum, talc, and agricultural limestone. We cover the full cage mill lineup, including single-row and multi-row configurations, on our dedicated cage mills and pulverizers page.
