This project is a basalt crushing and sand making project with an annual output of 3.4 million tons. In the actual operation of hard rocks such as basalt, high requirements are placed on equipment and production processes. The customer highly recognized SBM's rich experience and successful projects in hard rock crushing, and finally decided to cooperate with SBM. SBM designed and completed all aspects of process design, equipment installation, and plant construction.
To build a green premium mine production line, the entire project was rigorously constructed according to SBM's design concepts of "digitalization, intelligence and greenification". During the project planning and construction period, SBM engineers were stationed on site for a long time to fully research and customize solutions based on the plant terrain. A modular and intensive design process approach was adopted to significantly reduce land, belt conveyors and cable usage. The overall plant layout is scientifically reasonable, with clear zoning and orderly sparse and dense areas, ensuring the customer's goal of lean production management.
The production line adopts a three-stage crushing process, undergoing primary, secondary and fines crushing to screen out 0-3mm premium fine sand in layers, and can flexibly adjust the particle size of finished products according to market demands. The mature production line process guarantees the quality of finished aggregate to meet international aggregate standards and road aggregate standards.
The main machines selected are SBM's advanced jaw crusher, single cylinder hydraulic cone crusher, multi-cylinder hydraulic cone crusher and vertical shaft impact crusher, achieving shaping while sand making to meet customers' need for high-quality aggregate.
A dry process production model was constructed with a fully enclosed plant. Dust suppression devices were set up at dust-prone areas to effectively reduce dust, control diffusion and meet emission standards.
Intelligent control enables automatic loading, unloading and protection, with all operations centralized in the control room to significantly reduce production management and labor costs.
During installation, nearly 100 SBM service team members were stationed on site for a long time, working overtime to closely monitor project progress and fully support project construction.
SBM Industrial has been dedicated in the sandstone equipment manufacturing industry for over 30 years. It has continuously strengthened and improved materials and manufacturing processes, helping sandstone production enterprises reduce production costs.
Currently, SBM has successfully helped clients build numerous intelligent and green sandstone demonstration industrial parks across China, winning recognition from the industry and customers.
As a primary crusher, the basalt jaw crusher is suitable for coarse and medium crushing of hard basalt rocks. Its crushing cavity design matches the mutual movement trajectory of the swing jaw and fixed jaw to achieve enhanced crushing performance.
Basalt jaw crusher is engineered with durable materials to withstand the high abrasiveness of basalt rock. Their heavy-duty frames and components ensure longevity and reliability in demanding environments.
One of the key attributes of jaw crushers is their high crushing ratio. This means they can efficiently reduce large basalt blocks into smaller, more manageable sizes, making them suitable for various applications.
Basalt jaw crushers typically feature adjustable discharge settings, allowing operators to customize the size of the crushed material. This flexibility is crucial for meeting specific project requirements.
Downstream secondary and tertiary crushing duties are well-suited to reliable basalt cone crushers. The multi-cylinder hydraulic cone crusher uses advanced crushing techniques for optimizing mineral processing.
Specifically, the cone crusher adopts the laminated crushing principle to achieve simultaneous crushing and discharging. Its eccentric shaft adopts a laminated stress overload protection device to prolong service life.
The adjustable controlling system on the cone crusher enables setting changes conveniently via a hydraulic system to control discharge port size. This facilitates production of uniformly sized cubical aggregates for asphalt and concrete mixing.
Tertiary crushing of the high-hardness basalt employs the advanced spring cone crusher. It features an optimal combination of crushing speed, throw, and cavity design. The adjustable eccentric sleeve increases crushing ratio for meeting diverse downstream processing requirements.
This approach of optimized primary, secondary and tertiary crushing stages leveraging specialized basalt jaw and cone crushers ensures reliable production to meet the high capacity and exacting quality demands of this project.
In the future, SBM looks forward to cooperating with more enterprises to contribute to the development and construction of the country. Over the past three decades, it has refined materials, optimized production techniques and delivered huge benefits in cost savings for sand and gravel producers.
