How to chose the concrete crusher

The choice of concrete crusher needs to be based on a comprehensive consideration of the specific scenario and requirements. Below is an analysis of the characteristics and applicable scenarios of different types of equipment:

1、Selection by Material Characteristics
High-hardness concrete (including reinforcing steel)

Recommended equipment: Jaw crusher, cone crusher, mobile crushing station (with rebar shearing device).

Features:
Jaw Crusher: As a coarse crushing device, it has a deep crushing chamber with no dead zones, large feed particle size (e.g., 600-1500mm), and uniform output, suitable for processing large concrete blocks. Its wear-resistant materials and low-noise design are suitable for long-term operation, and it comes in various models with a wide capacity range.
Cone Crusher: Utilizes the principle of layered crushing, with strong crushing force, suitable for medium-hard to ultra-hard materials (such as high-strength concrete). It produces a high cubic content in the finished product, reducing irregular materials and improving quality. Maintenance is convenient, and parts can be directly disassembled.
Mobile Crushing Station: Integrates crushing, screening, and conveying functions, equipped with a rebar shearing device to protect the main unit from rebar damage and reduce production costs. Suitable for mobile operations (such as building demolition and mining).

Low-hardness concrete

Recommended equipment: Impact crusher, hammer crusher.

Features:
Impact crusher: Utilizes impact principle for crushing, producing regular (cubic) particle shape, less stone powder, high wear resistance, and low operating costs. Suitable for medium and fine crushing stages, such as highways and high-rise buildings where material requirements are strict.

Hammer crusher: One-time crushing, producing uniform particle size and intact particles, resulting in high-quality finished products. Suitable for foundation projects with less stringent particle shape requirements (such as road filling and site leveling).

2、Selection based on production scale

Small projects (e.g., building renovation)

Recommended equipment: Small jaw crusher, hammer crusher, single mobile crushing station.

Features: Low output requirements, flexible equipment, and lower costs.

Large projects (e.g., stone quarries, building aggregate bases)

Recommended equipment: Multi-unit combined production line (e.g., jaw crusher + cone crusher + impact crusher).

Features: Large processing capacity, high output, meeting large-scale production needs. For example, a 3600-ton-per-hour aggregate project in Jiangxi Province uses four E-HSI798 crushers, each with a capacity of 900-1000 tons per hour.

3、Selection Based on Finished Product Requirements

High-quality aggregate (e.g., highways, high-rise buildings)

Recommended equipment: Impact crusher, cone crusher.

Features: Uniform particle size and regular shape, meeting strict engineering standards.

Foundation engineering (e.g., road filling, site leveling)

Recommended equipment: Hammer crusher.

Features: One-time molding, economical, meets basic requirements.

4、 Selection Based on Site Conditions

Confined space or frequent relocation

Recommended equipment: Mobile crushing plant (wheel-mounted or tracked).

Features: High mobility, rapid deployment, adaptable to complex terrain (e.g., building demolition, mine face relocation).

Large fixed production sites

Recommended equipment: Fixed crushing equipment (e.g., jaw crusher + cone crusher combination).

Features: Production line designed according to site layout, high efficiency, low cost.

5、Selection Based on Cost Budget

Limited Budget
Recommended Equipment: Jaw Crusher, Hammer Crusher.

Features: Low purchase cost, simple operation and maintenance, suitable for short-term or small-scale projects.

Long-Term Operation
Recommended Equipment: Cone Crusher, Mobile Crushing Station.

Features: Although the initial investment is higher, it has strong wear resistance, convenient maintenance, low long-term operating costs, and significant economic benefits.

6、 Typical Application Scenarios

Construction Waste Recycling
Recommended Equipment: Mobile Crushing Station (with rebar shearing device).

Case Study: Wuhan Qianzishan Circular Economy Industrial Park uses the E-HSI679 crusher to efficiently process construction waste and achieve resource utilization.

Mining
Recommended Equipment: Jaw Crusher + Cone Crusher combination.

Case Study: Huaxin Cement project uses the HC798 crusher to process dolomite, and the E-HSI6118 crusher is used in the Jinghong aggregate project, verifying its adaptability in the mining industry.

Highway Construction
Recommended Equipment: Impact Crusher.

Features: The finished product has a regular particle shape, which meets the requirements of highway aggregates.
