12（10-20mm）- gravel stone:
The particle size range is roughly between 10 and 20 mm. Some people also say that 12-stone refers to gravel with a diameter of 1 cm (i.e. 10 mm) to 2 cm.
The volume is about 8 cubic centimeters (this data is an estimate, the actual volume may vary depending on the shape and density of the stone).
13 (16-31.5mm) - gravel stone:
The particle size range is roughly between 16 and 31.5 mm. Some people also say that 13-stone refers to gravel with a diameter of 1.6 cm to 3.5 cm.
The normal dosage is maintained between 2.5 and 3 tons, and the actual value depends on the type and density of the stone.
The stone particle size that the customer receives should be 12 stone (between 10-20mm), which is often used in small-scale concrete configuration and steel bar pouring; it has a better slump, higher safety, and higher fluidity.
Commonly used equipment for producing 12-stone includes jaw crusher, cone crusher (or impact crusher), vibrating screen, feeder and conveyor belt, etc.
1. Jaw crusher:
• Function: Mainly used for coarse crushing of large stones, providing suitable particle size for subsequent fine crushing equipment.
• Features: large crushing ratio, simple structure, easy maintenance, suitable for processing stones of various hardness.
2. Cone crusher or impact crusher:
• Function: Used for medium or fine crushing, further crushing the coarsely crushed stones to a particle size range close to 12-stone.
• Features: Cone crusher is suitable for processing high-hardness stones, while an impact crusher is more suitable for medium and low-hardness stones, and both can provide better particle shape control.
3. Vibrating screen:
• Function: Screen the crushed stones to separate particles that meet the particle size requirements of 12-stone.
• Features: high screening efficiency and large processing capacity. The screen can be adjusted as needed to meet different particle size requirements.
