How to Select a Grizzly Feeder for Iron Ore 230 TPH in Mauritania

Mauritania‘s Iron Ore Renaissance: A Market Poised for Expansion

Mauritania stands as a significant player in Africa’s iron ore industry, with state-owned SNIM consistently exceeding 14 million tonnes in annual sales for three consecutive years. In 2025, SNIM sold 14.7 million tonnes of iron ore, surpassing the 14-million-tonne threshold for the third year in a row, with a 2026 target set at 15.5 million tonnes. The company operates mines in Zouerate and exports via the port of Nouadhibou to Europe and China, with products including 52% Fe lump, 58% Fe fines, and 66% Fe concentrate. Beyond SNIM‘s existing operations, Mauritania is advancing several transformative projects. The Al-Aouj iron ore project in Tiris Zemmour province, with an overall investment exceeding $2 billion, is now entering its implementation phase. The deposit hosts approximately 4.4 billion tonnes of magnetite resources, with a two-phase development plan targeting 11.3 million tonnes per year of iron ore concentrate at an average grade of 66.5% Fe over a 40-year mine life. The Atomai iron ore project, a Saudi-Mauritanian joint venture supported by $900 million in financing from the Islamic Corporation for the Development of the Private Sector, is expected to produce approximately 10 million tonnes per year of high-grade direct-reduction iron ore pellets. SNIM has also announced plans to raise annual production to 45 million tonnes by 2031. For operators processing iron ore at 230 TPH, selecting the right grizzly feeder is the critical first step in the crushing circuit.

The Critical Role of Grizzly Feeders in Iron Ore Processing

A grizzly feeder performs two essential functions in an iron ore crushing plant: uniform feeding of run-of-mine material to the primary crusher, and pre-screening to remove fines and undersized material before it enters the crusher. This dual function improves plant throughput, reduces crusher wear, and minimises the risk of clogging. For a 230 TPH iron ore operation in Mauritania, the grizzly feeder must be engineered to withstand the extreme abrasion and impact loads generated by hard, dense iron ore. Mauritanian iron ore, particularly from the Tiris Zemmour region, is characterised by high density and significant magnetite content, which places exceptional stress on feeding equipment. The feeder must also accommodate large feed sizes—typically up to 1,000 mm for run-of-mine ore from open-pit operations. As a rule of thumb, the feeder capacity should exceed the crusher capacity by 25–35% to ensure an even flow of material and prevent crusher starvation.

Key Selection Criteria for a 230 TPH Iron Ore Grizzly Feeder

Selecting the optimal grizzly feeder for a 230 TPH iron ore application requires evaluation of several critical parameters. Feed size is the starting point: the feeder‘s grizzly section must accept the maximum lump size from the mine while allowing undersized material to bypass the crusher. Grizzly bar spacing is typically set to match the closed side setting of the primary crusher, ensuring that only material requiring crushing is fed to the crusher. Feeder width and length must be matched to the throughput and the material‘s bulk density—iron ore‘s high density means that a wider, longer feeder may be required than for lighter materials at the same tonnage. Motor power and vibration amplitude must be sufficient to convey dense, heavy material without stalling, even under surge loading from haul trucks. Wear protection is paramount: the feeder trough should be lined with high-manganese steel or wear-resistant plate to withstand continuous abrasion from iron ore. Installation slope typically ranges from 5 to 10 degrees, with the optimal angle depending on material characteristics and site layout.

Model Selection: Matching Capacity to Application

For a 230 TPH iron ore application, several proven grizzly feeder models are available. The ZSW series offers models such as the ZSW-380×95, which delivers a capacity of 160–230 TPH with a maximum feed size of 500 mm and 11 kW motor power—closely matching the target throughput. Larger models in the ZSW range can accommodate higher capacities if future expansion is anticipated. The GZT series vibrating grizzly feeder is another robust option, engineered specifically for primary feeding and pre-screening in mining applications. Both series feature heavy-duty vibration motors with dust-proof and waterproof enclosures (IP55/IP65 protection), ensuring reliable operation in Mauritania‘s demanding desert conditions. When selecting a model, operators should also consider the variable frequency drive (VFD) option, which enables precise, real-time control of the feeding rate to match downstream conveyor and crusher capacity. This is particularly valuable in iron ore operations where feed characteristics can vary across different pit zones.
