250-300 t/h Rock Crushing Production Line Solution

In the sand and gravel aggregate and mining crushing industry, the production capacity demand of 250-300 t/h usually means large production lines and high-hardness rock crushing challenges. How to configure an efficient, stable and low-energy crushing production line? This article will deeply analyze the optimal equipment combination and provide a unique production line optimization solution to help you reduce operating costs and improve return on investment.

Industry pain points and solutions

In the production of large-scale sand and gravel aggregates, production lines with a capacity of 250-300 t/h face three core challenges:

• Low hard rock crushing efficiency (high-hardness materials such as granite/basalt)

• Production capacity bottleneck caused by poor equipment matching

• High energy consumption and maintenance costs

In response to these problems, we innovatively proposed the "three-stage classification + intelligent regulation" solution, which achieves the following by optimizing the equipment combination:

1. Crushing efficiency increased by 30%

2. Energy consumption reduced by 25%

3. Equipment service life extended by 40%

Innovative process flow analysis

1. Primary crushing stage (jaw crusher-dominated)

• C100 jaw crusher adopts a "deep V-shaped" crushing chamber design, and the bite angle is optimized to 22° to achieve one-time crushing of large rocks

• Equipped with a hydraulic cavity cleaning system, the material jamming processing time is shortened by 80%

2. Secondary crushing stage (cone crusher combination)

• The dual HP300 cone crushers adopt a "1 main 1 standby" configuration to ensure continuous production

• The lamination crushing principle makes the needle-like content <10%, which is far better than the industry standard

3. Intelligent screening system

• Three 2YK2160 vibrating screens form a "two-stage screening" system:

The first stage: 50-70mm coarse screen (2 in parallel)

The second stage: 5-30mm fine screen (1)

• The screen is made of polyurethane + rubber composite material, and its life is increased by 3 times
