As the "first checkpoint" of the crushing production line, the coarse crushing equipment undertakes the key task of initially crushing large raw stones into smaller particles in mining and sand and gravel aggregate production. Choosing an efficient and durable rough crushing equipment can not only improve overall production efficiency, but also reduce operating costs.

一、 The important role of coarse crushing equipment in the field of mining machinery crushing

1. Rapid processing of large raw materials: Coarse crushing equipment can quickly crush the mined raw materials (such as granite, limestone, etc.) to a suitable particle size for medium to fine crushing, laying the foundation for subsequent processes.

2. Reduce energy consumption and costs: By reducing the volume of materials in advance through the coarse crushing process, the load on the medium and fine crushing equipment can be significantly reduced, the equipment life can be extended, and energy consumption can be saved.

3. Ensure the continuity of the production line: Stable rough crushing capacity is the core of efficient operation of the production line, avoiding complete shutdown due to equipment failure.

二、 How to choose the appropriate rough crushing equipment?

First move: Clarify material characteristics and production requirements

Material hardness and composition: For high hardness ores (such as granite), equipment with high compressive strength (such as jaw crushers) should be selected; Adhesive materials require anti blocking design.

Capacity demand: Select the matching model based on the hourly processing capacity (such as 100-1500 tons) to avoid "big horses pulling small cars" or overloaded operation.

Particle size requirements for discharge: The size of the material after coarse crushing needs to be adapted to subsequent processes (such as secondary crushing or direct screening).

Second move: Pay attention to equipment performance and energy consumption

Crushing ratio: High crushing ratio equipment can reduce the number of crushing sections and save investment costs.

Wear resistance and maintenance convenience: Key components such as jaw plates and rotors are made of high-strength alloy materials, and the structural design is easy to maintain.

Energy consumption and environmental protection: Choose energy-saving motors and low-noise designs that conform to the trend of green production.

Third move: Investigate brand technology and service guarantee

Prioritize choosing brands with mature technology and good reputation to ensure stable equipment operation and after-sales support capabilities.

三、 Common types of rough equipment

Jaw crusher - preferred for coarse crushing of medium and high hardness materials

Henan Gaofeng Heavy Industry's jaw crusher demonstrates the power of primary crushing with its powerful crushing force! Deep V crushing chamber, with plenty of feed and no blockage; Integrated motor bracket, more convenient for transportation and installation; Wedge block adjustment discharge port, easily adjust the discharge particle size in 3 minutes; The hourly output can reach 1500 tons, with high production capacity and low failure rate!

Heavy hammer crusher - the king of cost-effectiveness for small and medium-sized projects

The heavy hammer crusher of Gaofeng Heavy Industry is widely used in many fields such as mining, smelting, building materials, transportation, water conservancy, etc; Breaking the top twice, forming in one go, it can reduce costs by about 40% for products of the same level; The product features a design without ribs, can be broken by dry and wet conditions, and has adjustable discharge. It does not cause machine jamming or blockage, and its performance is superior to other products of the same level, simplifying the secondary crushing process.
