With the continuous advancement of infrastructure construction, the quality requirements for sand and gravel, as core building materials, are steadily increasing. Sand and gravel with excessive mud content or impurities can seriously affect the strength of concrete, thereby threatening the quality of construction projects. Therefore, efficient and stable sand washing equipment has become an indispensable key part of the sand and gravel processing process. Today, let's take an in-depth look at a highly favored sand washing tool in the industry—the LSX series spiral sand washing machine.

LSX Series Spiral Sand Washer: Analysis of Core Working Principle

The LSX series spiral sand washer achieves efficient cleaning of sand and gravel through the combined action of gravity and water flow. The equipment mainly consists of core components such as a motor, gearbox, spiral shaft, water tank, and frame. During operation, the motor drives the spiral shaft to rotate slowly through the gearbox, and the raw sand and gravel enter the water tank through the feeding port. Under the pushing action of the spiral shaft, the sand and gravel fully mix and rub with the water in the tank, and impurities such as soil and dust on the surface of the sand are washed away by the water flow. At the same time, lighter impurities (such as soil particles and dust) are discharged from the overflow port with the water, while the cleaned sand and gravel are pushed out from the discharge port by the spiral shaft, completing the entire sand washing process.

Compared with traditional sand washing equipment, the LSX series uses a spiral structure design, allowing the sand and gravel to move more efficiently during the cleaning process, ensuring more thorough contact with water, achieving a more uniform cleaning effect, and also reducing sand and gravel loss.

What are the core advantages of the LSX series spiral sand washing

 machine, and why has it become the industry's preferred choice?

1. Energy-efficient, enhancing production efficiency

The LSX series spiral sand washing machine adopts an optimized motor matching and transmission structure, resulting in higher power transmission efficiency and a greater amount of sand washed per unit of time. Take the commonly used LSX-915 model as an example; it can process 50-120 tons per hour, meeting the production needs of sand and gravel plants of different scales. At the same time, the equipment consumes relatively low energy during operation. Compared to traditional equipment of the same type, it has a significant energy-saving effect, and long-term use can greatly reduce production energy costs.

2. Good cleaning effect, high-quality finished product

The equipment features a multi-stage spiral blade design, with blade angles precisely calculated to ensure that sand and gravel are thoroughly tumbled and rubbed in the water tank, effectively removing impurities such as mud and dust from the surface. Sand and gravel cleaned by this equipment can have a mud content controlled below 1%, meeting national standards for construction sand. The finished sand and gravel have uniform particle size and high cleanliness, making them suitable for direct use in high-end engineering projects such as concrete mixing and road paving, thereby enhancing the market competitiveness of the sand and gravel products.

3. Stable structure, highly durable

The LSX series spiral sand washing machine's key components, such as the spiral shaft and blades, are made of high-strength, wear-resistant steel. After quenching and wear-resistant treatment, they have high hardness and strong wear resistance, making them suitable for harsh working environments in mines and sand and gravel plants, effectively reducing component wear and extending equipment service life. At the same time, the machine's frame adopts a welded reinforced structure, providing strong stability, low vibration, and low noise during operation, which reduces the frequency of equipment maintenance.

4. Easy to operate and convenient to maintain

The equipment features an intelligent operation design and is equipped with a clear control panel, allowing staff to operate it proficiently after minimal training. At the same time, the equipment has a well-arranged structural layout, with key components that are easy to disassemble and replace. Routine maintenance (such as lubrication, cleaning, and component inspection) is convenient and efficient, reducing equipment downtime and enhancing production continuity. In addition, the equipment is equipped with an overload protection device, which automatically shuts down the machine in case of material jams, overloads, or other abnormal situations, preventing damage to core components such as the motor and minimizing failure-related losses.

5. Wide applicability and strong compatibility

The LSX series spiral sand washing machine is not only suitable for cleaning various sand and stone raw materials such as river sand, mountain sand, quartz sand, and pebbles, but can also be used for cleaning and purifying materials like construction aggregates, mine tailings, and chemical raw materials. Whether for a stationary sand and stone processing plant or a mobile crushing and sand washing production line, it can be flexibly adapted to meet production needs in different scenarios.

Applicable Scenarios for the LSX Series Spiral Sand Washing Machine

Mining and Quarrying Sector: Used for cleaning raw sand and gravel from mines, removing impurities such as soil and rock debris mixed in during the mining process, and improving the quality of mined sand and gravel;

Sand and Gravel Processing Sector: Serves as the core cleaning equipment in sand and gravel processing production lines, enabling full-process cleaning from raw material crushing to finished product, and producing construction sand that meets standards;

Infrastructure Construction Sector: Used on-site for cleaning sand and gravel materials in road, bridge, tunnel, and real estate construction projects, ensuring the quality of construction sand;

Chemical and Building Materials Sector: Used for cleaning and purifying chemical raw materials such as quartz sand and feldspar sand, as well as ceramic raw materials, enhancing raw material purity and ensuring product quality.

Key Points for the Use and Maintenance of LSX Series Spiral Sand Washer

1. Daily Use Precautions

Before starting the machine, check the connections of all parts of the equipment to ensure bolts are tightened and there is sufficient lubricating oil; it is strictly forbidden to operate the equipment without water to avoid dry friction between the screw blades and the water tank, which could cause parts damage; during feeding, feed evenly to prevent excessive material from overloading the equipment and causing jamming; regularly check if the overflow outlet is clear to prevent debris buildup and blockage that could affect cleaning performance.

2. Regular maintenance

Inspect key components of the equipment such as the screw shaft, blades, and bearings weekly to check for wear, deformation, or other issues, and replace them promptly if necessary; perform a thorough lubrication of the equipment once a month, adding the appropriate type of lubricating oil to ensure smooth operation of the transmission components; regularly clean the sediment in the water tank to prevent the accumulation of impurities from affecting the equipment's operational efficiency; when the equipment is not in use for an extended period, drain any accumulated water, remove remaining sand and gravel, and apply anti-rust treatment to parts prone to corrosion to prevent rusting.

Summary: Choosing the right sand washing equipment helps promote high-quality development in the industry
