Minerals Coarse Crusher

What is Minerals Coarse Crusher?

Minerals Coarse Crusher is a special equipment for preliminary crushing of mineral raw materials. It is mainly used to crush large pieces of mineral raw materials after mining into medium particle size, laying the foundation for subsequent fine crushing, grinding and other processes. It can crush minerals with an initial particle size of less than 1600 mm, depending on the equipment model. For example, the jaw coarse crusher can process ores with a side length of 800-1200 mm. In terms of output, a single machine can reach 50-1000 tons per hour, which is suitable for large-scale production scenarios such as mining and mineral processing. The discharge particle size is usually controlled at 20-150 mm, and the particle size can be flexibly adjusted by adjusting the gap of the crushing chamber. Its core function is to efficiently reduce the particle size of mineral raw materials, reduce the load of subsequent processing equipment, and improve the comprehensive processing efficiency of minerals. It is widely used in the rough processing of minerals such as metal ores, non-metallic ores, and building stones.

What types of ores can be crushed by Minerals Coarse Crusher?

Minerals Coarse Crusher can be used to crush high-hardness, medium-low-hardness and high-mud content minerals with a particle size of ≤1600mm.

For high-hardness ores (Mohs hardness ≥7): such as granite, basalt, iron ore, and quartzite, it is recommended to use a jaw crusher or a gyratory crusher.

For medium-low-hardness ores (Mohs hardness 3-6): such as limestone, gypsum, coal gangue, and phosphate rock, a heavy hammer crusher or an impact crusher can be selected.

For ores with high mud content: such as clay minerals, an anti-blocking jaw crusher or a grateless heavy hammer crusher is required.

What types of Minerals Coarse Crusher are there?

Crusher type	Applicable minerals	Feed size	Discharge size	Capacity range	Advantages
Jaw crusher (jaw crusher)	High hardness ore (granite, iron ore, copper ore, etc.)	≤1200mm	100-350mm (adjustable)	60-1160 tons/hour	Simple structure, easy maintenance, wear resistance, especially suitable for coarse crushing of high-hardness ores.
Gyratory crusher	Large-scale mines (iron ore, gold ore, limestone, etc.)	≤1525mm	150-300mm	2000-10000 tons/hour	Continuous crushing, high production capacity, low power consumption, suitable for large-scale ore dressing plants.
Heavy hammer crusher	Medium and low hardness ores (limestone, coal gangue, gypsum, etc.)	≤1000mm	30-80mm (adjustable)	60-3000 tons/hour	Large crushing ratio, one machine for multiple uses, suitable for small and medium-sized production lines.

What are the advantages of Minerals Coarse Crusher?

Minerals Coarse Crusher has significant technical and cost advantages: in terms of crushing efficiency, the jaw crusher has a deep cavity design to enhance the feeding capacity, the gyratory crusher has a large-angle crushing cavity to improve the crushing efficiency, and the heavy hammer crusher uses impact crushing to reduce over-crushing and improve the yield rate; in terms of intelligence, modern equipment is equipped with an Internet of Things monitoring system, which optimizes operating parameters in real time through temperature and vibration sensors, effectively reducing the equipment failure rate; in terms of operating costs, the power consumption per ton of the gyratory crusher is 0.8-1.2kW・h lower than that of the jaw crusher, saving more than 1.5 million yuan in electricity bills annually. The life of the gyratory crusher liner of some brands (such as Metso) has been increased by 3 times, saving up to 6.25 million yuan in annual maintenance costs, taking into account both efficient production and economic and environmental protection.

What is the principle of Minerals Coarse Crusher?

The working principle of Minerals Coarse Crusher is mainly divided into: Extrusion crushing (jaw crusher, gyratory crusher): crushing ore by the extrusion of the moving jaw/moving cone and the fixed liner; Impact crushing (heavy hammer crusher, impact crusher): using high-speed rotating hammer to impact ore, suitable for brittle minerals
