In the field of mining and aggregates production, coarse crushing equipment, as the first crushing machine, can break the large block of stones into small particles. Selecting a efficient and durable coarse crushing equipment not only improves the whole production efficiency, but also reduces management cost.
I. Key roles of the coarse crushing equipment in mining crushing field
Quickly processing large block of raw materials: Coarse crushing equipment can quickly break the raw stone materials (granite, limestone) into suitable particle size, better for the medium and dine crushing.
Reducing energy consumption and cost: By reducing the volume of materials in advance through the coarse crushing process, the load on medium and fine crushing equipment can be significantly reduced, the service life of the equipment can be prolonged, and energy consumption can be saved.
Guarantee the continuity of production line: A stable coarse crushing ability is the core for the efficient operation of the whole production line, to avoid the complete shutdown of the entire line due to equipment failure.
II. How to choose the suitable coarse crushing equipment?
Marital hardness and composition: The hardness, measured by its Work Index, directly dictates the type of crusher and the wear materials you’ll need. Jaw and gyratory crushers excel at handling very hard and abrasive rocks, while impact crushers are better for softer, less abrasive materials.
Production capacity requirement: Choose the matched type of crusher machine according to the processing capacity per hour.
Input Size & Output Size: The size of the material after coarse crushing should be compatible with the subsequent processes (such as secondary crushing or direct screening). The crusher’s feed opening must accommodate your largest rocks, and its design must be capable of achieving your target reduction in a single stage (primary crushing) or as part of a circuit.
Wear resistance and maintenance convenience: Key components (such as the jaw plate and rotor) are made of high-strength alloy materials, and the structural design is convenient for maintenance.
Energy consumption and environmental protection: Selecting energy-saving motors and low-noise designs conforms to the trend of green production.
III. Common types of coarse crushing equipment
Jaw crusher – The preferred choice for primary crushing of medium and high hardness materials
Luoyang Dahua jaw crusher, deep V-shaped crushing cavity, with more material intake and no clogging. Integral motor bracket, more convenient for transportation and installation; Adjustable discharge opening can be easily adjusted within 3 minutes by wedge block. The hourly output can reach 1,500 tons, with high production capacity and low failure rate.
Gyratory crusher – The preferred choice for large-scale mining projects
Luoyang Dahua gyratory crusher is a new type of coarse crushing equipment with large production capacity, high efficiency and intelligence. The main shaft control system ensures more stable particle shape. Increasing the inclination Angle of the crushing cavity and extending the crushing surface can lead to higher efficiency and lower production costs. It is applicable to the crushing of various materials of different hardness such as limestone, basalt and granite. It has a large processing capacity and is suitable for continuous operation in large-scale mines.
Heavy hammer Crusher – The king of cost performance for small and medium-sized projects
Luoyang Dahua heavy hammer crushers are widely used in numerous fields such as mining, smelting, building materials, transportation, and water conservancy. One-time molding reduces costs by about 40% compared to the same level product. It features a no-grate design, is capable of both dry and wet crushing, and has adjustable output. It does not get stuck or clogged.
Luoyang Dahua Heavy Industry is a high-tech enterprise with research & development production, sales, and service. The mobile crushing station has been successfully applied in domestic and foreign mine crushing projects. The company has a professional R & D team, a strong after-sales team, from the equipment selection, site inspection, equipment manufacturing, installation, commissioning, delivery and other aspects for your service.
