The basalt sand and gravel production line is a key facility for processing hard basalt into sand and gravel for construction. The following is a detailed introduction to its process flow, equipment configuration, environmental protection and intelligent management:

Process flow

Raw material mining and pretreatment: Large pieces of basalt ore are evenly transported by vibrating feeders to jaw crushers for coarse crushing, reducing their particle size to a processable range and reducing transportation costs.

Medium and fine crushing and screening: The coarsely crushed materials are sent to cone crushers by belt conveyors for secondary crushing to form particles below 20mm. Multi-stage vibrating screens are graded according to particle size, 0.5-5mm for sand, 5-20mm for aggregate, to improve the yield rate.

Sand making and shaping: Materials that meet the particle size requirements enter the impact sand making machine, and the stone powder is stripped by high-speed impact to produce machine-made sand. The sand and gravel shaping machine further removes needle-like particles and optimizes the sand grading.

Dust control and wastewater treatment: The pulse dust collector achieves a dust collection rate of 99%, meeting the national environmental protection emission standards. Wastewater is recycled after being filtered in the sedimentation tank to form a closed-loop circulation system to achieve zero pollution.

Intelligent control: PLC control system monitors the operating status of equipment in real time, and AI algorithm optimizes energy consumption. The Internet of Things platform supports remote control, reducing labor costs by more than 30%.

Equipment configuration

Crushing equipment: Jaw crusher is responsible for coarse crushing, cone crusher is responsible for medium and fine crushing, and vertical shaft impact crusher (sand making machine) completes sand making and shaping. The three form an efficient crushing system.

Screening equipment: Multi-stage vibrating screens use screens with different apertures to achieve particle size classification, and circular vibrating screens perform final screening of sand making products.

Auxiliary equipment: Vibrating feeder ensures uniform transportation of raw materials, belt conveyor connects various links to achieve automatic transfer, and bucket elevator assists in vertical lifting of materials.

Environmental protection equipment: Pulse dust collector and closed-loop wastewater treatment system constitute a double environmental protection barrier to ensure clean and efficient production process.

Finished product application

Road paving: As high-speed rail track ballast and highway base material, its compressive strength can meet the needs of heavy-load transportation.

Construction field: Concrete aggregate can increase strength by 20% - 30%, and curtain wall dry hanging stone shows the beauty of natural texture.

Environmentally friendly materials: Permeable bricks and ecological slope protection products have both functional and ecological benefits.
