ST3.8™ sand washer advantages
Efficient screening and sand washing capabilities
The Lokotrack ST3.8™ is equipped with a multi-layer vibrating screen that can efficiently screen sand and gravel of different particle sizes. It uses a unique screening system to effectively separate larger particles from fine particles to ensure the high purity of fine sand. In addition, with the high-pressure spray water system, it can fully remove impurities on the surface of sand and gravel, such as clay and soil, to improve the quality of sand and gravel. The combination of sand washing and screening functions enables it to provide stable productivity in multiple industries.
Fine sand recovery system reduces waste
The ST3.8™ is equipped with an advanced fine sand recovery system, which efficiently separates fine sand from the mixed cement slurry through rotation and centrifugal force. This can minimize the loss of fine sand and re-invest the recovered fine sand in the production process. This innovative design not only improves production efficiency, but also greatly reduces the waste of raw materials, helping companies save costs.
High flexibility and mobility
As a mobile sand washer, the Lokotrack ST3.8™ is compact in design and sturdy in structure, and can easily cope with different working environments. The equipment is equipped with a crawler chassis, which can be quickly moved and dispatched to adapt to various construction sites, especially suitable for changing site conditions. Whether it is a mountainous mining area or a construction site, ST3.8™ can be put into use quickly, greatly improving work efficiency.
Intelligent control system
Lokotrack ST3.8™ is equipped with an intelligent control system that can monitor the equipment's operating status in real time and make optimization adjustments. The system can be adjusted through remote operation, reducing manual intervention and improving the automation level of the equipment. Through real-time data collection, the operator can monitor the screening effect, sand washing process and equipment status to avoid potential failures and downtime, reduce maintenance costs and improve equipment reliability.
Low energy consumption and environmentally friendly design
Lokotrack ST3.8™ is designed with energy saving and environmental protection in mind. The equipment's efficient screening and recovery system can significantly reduce water and energy consumption. At the same time, it is equipped with an advanced dehydration device that can effectively remove moisture from sand and gravel, avoiding the waste of water resources. The working principle and function of this equipment not only improve production efficiency, but also meet modern environmental protection requirements, reduce negative impacts on the environment, and is an ideal choice for sustainable development.
Working principle of ST3.8™ sand washer
The working principle of Lokotrack ST3.8™ sand washer is based on an efficient screening and fine sand recovery system. Its core function is to screen the sand and gravel through multiple layers of screens and effectively remove impurities in them through a water washing process to ensure high quality and high purity of the product. First, the material enters the machine through a feeder and enters the screening area, where it is initially screened by a vibrating screen. The screen separates large particles and oversized sand and gravel through high-speed vibration, while fine particles pass through the pores of the screen into the next sand washing process. During the screening process, Lokotrack ST3.8™ uses a spray water system to wash the sand and gravel, and the water flow washes away the dust and impurities adhering to the surface of the sand and gravel. During the sand washing process, fine sand and water are mixed to form a slurry, which is effectively recovered through a dedicated fine sand recovery system. This system separates the fine sand from the water through rotation and centrifugal force and re-transports it to the screening area or other aggregate system, thereby minimizing the loss of fine sand. At the same time, the multi-layer screens finely screen the materials of different particle sizes to ensure the particle uniformity of the finished sand and gravel. In addition, the design of the Lokotrack ST3.8™ sand washer makes it very suitable for mobile operations and can be flexibly transferred between multiple construction sites. Its efficient dewatering function effectively removes moisture from the sand and gravel, improving the dryness of the sand and gravel, which meets the strict requirements of the modern construction industry for sand and gravel quality. In summary, the Lokotrack ST3.8™ sand washer ensures efficient cleaning and grading of sand and gravel through processes such as vibration screening, spray water washing and fine sand recovery, and is suitable for various sand and gravel processing and sand washing needs.
