Basalt, with its high silicon content, hard texture, and excellent compressive strength, is a high-quality raw material for sand and gravel aggregate and an ideal natural high-performance material for the construction industry. Basalt sand and gravel processing requires a comprehensive process of geological survey, blasting, grading, and environmentally friendly sand production, achieving both efficient processing and ecological restoration.

Basalt is a highly hard stone that is difficult to crush, placing high demands on machine rigidity. Improper equipment selection can lead to severe wear of vulnerable parts and poor processing performance. Therefore, when configuring a basalt sand Making production line, consider using crushing equipment that utilizes a laminated principle to minimize production losses.

 

1. Raw Material Preparation

 

Basalt ore undergoes preliminary screening to remove impurities such as dirt and debris to ensure raw material purity.

 

A vibrating feeder is used to evenly transport the raw material to the primary crushing equipment to prevent clogging.

 

2. Primary Crushing Stage

 

A jaw crusher is used to crush lumps with a particle size of 300 mm or more to less than 50 mm. Jaw crushers offer high throughput and efficiency, making them suitable for high-hardness materials, achieving a crushing ratio of 4-6x.

 

3. Secondary and fine crushing stage

 

Basalt is very hard and difficult to crush. For secondary and fine crushing, hydraulic cone crushers using the laminated crushing principle are often used. This utilizes the inter-material crushing action to reduce impact and wear on machine components.

 

A dual-stage cone crusher, combining a single-cylinder hydraulic cone crusher with a multi-cylinder hydraulic cone crusher, can be used to reduce machine wear, optimize the stone particle shape, and achieve higher production output.

 

4. Sand making and shaping stage

 

If the stone is to be further crushed into manufactured sand, a vertical impact crusher can be used for sand making and shaping. This equipment can produce and shape the stone, resulting in fine-grained, uniform sand particles, meeting the sand requirements of most construction industries.
