Gravel is a crucial component of projects like concrete and building materials, and its specifications and quality directly impact the quality of the project. To meet the needs of different projects, gravel is available in a variety of sizes and models. Furthermore, different crushing equipment plays a key role in gravel production. This article will provide a detailed introduction to common gravel sizes and models, as well as recommended crushing equipment.

1. Gravel Specifications

Gravel specifications are primarily categorized by particle size. Common construction gravel specifications are as follows:

0-5 Gravel: Sand with a particle size of 0-5mm.

5-10 Gravel: Crushed stone with a particle size of 5-10mm.

10-20 Gravel: Crushed stone with a particle size of 10-20mm.

16-31.5 Gravel: Crushed stone with a particle size of 16-31.5mm.

20-40 Gravel: Crushed stone with a particle size of 20-40mm. In addition, gravel can be categorized into continuous grading and single-grain grading based on the grading method:

Continuous grading: Gralparticle sizes vary, including various sizes, such as 5-10mm and 5-20mm. This allows for interstitial fill and improves concrete density.

Single-grain grading: Gralparticle sizes are uniform, such as 10-20mm and 20-40mm, and are suitable for concrete applications.

II. Common Crushing Equipment and Their Characteristics

The selection of crushing equipment is crucial in the gravel production process. Different equipment is suitable for crushing different types of stone. The following are several common crushing equipment and their characteristics:

1. Jaw Crusher

Feed Size: ≤1200mm

Production Capacity: 1-1000t/h

Applicable Materials: Coarse crushing of various hard, medium-hard, and soft materials

Features: Strong crushing capacity, stable operation, and simple operation. This is a commonly used primary crushing equipment in the gravel crushing process, producing finished material sizes ranging from 10-350mm.

2. Impact Crusher

Feed Size: ≤800mm

Production Capacity: 30-800t/h

Applicable Materials: Medium-to-fine crushing of medium-hard and soft materials

Features: Excellent particle shape, resulting in cubic, uniformly sized stones. This is a common secondary crushing equipment, with a particle size range of 5-60mm.

3. Cone Crusher

Feed Size: ≤560mm

Production Capacity: 12-2181t/h

Applicable Materials: Medium-to-fine crushing of hard materials such as granite, river pebbles, and marble

Features: Highly durable, suitable for crushing hard materials, with a particle size range of 3-60mm.

4. Sand Making Machine

Feed Particle Size: ≤1200mm

Production Capacity: 3-3000 t/h

Applicable Materials: Medium-to-brittle materials such as limestone, gangue, and coal

Features: Single-stage crushing and shaping, high crushing ratio, capable of crushing materials between 600-1200mm to less than 40mm.

III. Gravel Production Line Equipment Configuration Options

The configuration options for a gravel production line should be selected based on specific needs. The following are several common configuration options:

Option 1:

Equipment: Vibrating Feeder + Jaw Crusher + Cone Crusher + Sand Making Machine + Circular Vibrating Screen + Belt Conveyor

Features: High crushing ratio, fine finished particle size, high output, long equipment life, and low maintenance costs.

Option 2:

Equipment: Vibrating Feeder + Jaw Crusher + Impact Crusher + Sand Making Machine + Circular Vibrating Screen + Belt Conveyor

Features: Suitable for crushing soft materials, low initial investment cost, but high maintenance costs. Option 3:

Equipment: Mobile Crusher + Mobile Screen

Features: Flexible and removable, it can be driven directly to the crushing site, making it suitable for projects requiring high mobility.
