iron ore Crushing Solutions

Yes.

Iron ore is hard and highly abrasive. Many concentrators struggle with fine crushing—either the equipment can’t crush it properly or the product particle size is inconsistent. Cone crushers typically produce a discharge size of 20-30mm, but the material often contains a mix of coarse particles and fines, resulting in uneven feed for the ball mill and lower grinding efficiency.

The Hua Sheng Ming 1008 roll crusher is designed specifically to address this challenge.

20mm Feed to 3mm Discharge – What Happens in Between?

Material entering between the two rolls is not smashed—it is crushed by compression. The rolls rotate in opposite directions, applying sustained compressive pressure. Iron ore fractures along mineral boundaries within the roll gap, rather than being shattered into powder by impact hammers.

The difference between compression and impact crushing is significant. Impact crushers produce more fines alongside oversized particles, resulting in a wide particle size distribution. Roll crushers produce a more concentrated particle size with minimal over-grinding.

What Feed Size Can the 1008 Handle?

20mm iron ore feed is well within the machine’s capacity. The 1008 hydraulic roll crusher accepts feed sizes up to 50mm and discharges from 1-5mm, fully covering 20mm iron ore feed requirements. It processes approximately 60 tons per hour, powered by two 45kW motors, making it suitable for small to medium-scale crushing operations.

Discharge size is controlled online through the hydraulic system, adjustable to below 3mm without stopping the machine or changing screens. Once adjusted, the material feeds directly to the ball mill, significantly reducing mill load.

How Long Does the Roll Shell Last with Iron Ore?

Iron ore’s high hardness and quartz content cause rapid wear on roll surfaces. The 1008 roll shell is manufactured using Hua Sheng Ming’s proprietary formulation and process, offering strong wear resistance for continuous iron ore processing. Service life ranges from several months to years depending on feed material characteristics.

Compared to hammer crushers that require hammer replacement every few days, the roll crusher offers much longer maintenance intervals, fewer downtime events, and more continuous production.

What Scale of Concentrator Is This Solution Suitable For?

The Hua Sheng Ming 1008 processes approximately 50-80 tons per hour, making it ideal for small to medium-scale concentrator fine crushing sections. The unit can operate independently or be integrated into existing production lines, replacing cone crushers or impact crushers without major site modifications.
