LZZG track-mounted mobile sand washing & recycling plan is a mobile sand and gravel washing machine with crawler, which is widely used for washing and selecting in many industries such as sand and gravel plants, mines, building materials factories, transportation, chemical industry, water conservancy and hydropower, and concrete mixing.
LZZG series introduced products to absorb foreign advanced technology, and designed combined with sand field actual situation. It can effectively reduce the loss amounts of fine material; solve problems of end product such as relatively high fineness modulus and relatively low stone powder content. The fine material can be recycled as high as 95%, with incomparable technical and economic advantages.

The Crawler Type Wash Plant achieves mobile washing operations via its crawler chassis, offering greater operational flexibility. It is powered by diesel and electricity, allowing for either external power supply or standalone diesel operation. The double-washing process ensures excellent sand cleaning performance, effectively handling materials with high mud content. Additionally, it recycles wastewater to achieve a high resource utilization rate. The unit can be equipped with satellite positioning and lock functions, supporting various commercial sales models and cooperation forms. This mobile plant features advanced technology, intelligent monitoring, and a control system capable of wireless remote monitoring, data transmission, data analysis, and remote control.
Structures
It is primarily composed of a power system, a travel system, a hydraulic drive and steering system, a working system, and a control system. It can also be equipped with remote positioning and locking, fault monitoring, data collection, wireless remote control, and other auxiliary systems. Key components include the crawler device, hydraulic motor, planetary reducer, generator set (comprising an engine and generator), hydraulic workstation, control cabinet, frame, working device (spiral sand washing + wheel sand washing + fine sand recovery + dehydration), working platform, remote control unit, and optional satellite positioning mechanism, information monitoring, and data transmission systems.
Working Principle
Screened quality sand is fed into a spiral washing tank via a chute for primary washing. The spiral classifier rotates to tumble and grind the material, effectively removing impurities from the surface of the sand.
The washed sand is conveyed by the blades into the bucket wheel sand washer. Mud water and low-density materials are removed and pumped to a desander cyclone for recycling, then also fed back into the bucket wheel sand washer.
As the buckets rotate, the sand is cleaned in the bucket wheel sand washer. The clean sand is then discharged onto a polyurethane screen for dewatering. Simultaneously, the mixture of mud water and fine particles is extracted to a secondary desander cyclone to recover fine sand, which is subsequently fed onto the polyurethane screen for dewatering. Finally, the fully dehydrated product from the high-frequency vibrating screen is transported to the stockpile via belt conveyor.
Features
1. Dual power supply options: diesel and electric. When grid electricity is available, the unit operates on electric power; in remote locations without electricity, it runs on a diesel generator set.
2. Enhanced operational flexibility enabling rapid relocation. Unlike traditional wheeled mobile sand washing plants, this tracked system can move forward, reverse, turn, and climb slopes independently without external traction.
3. Modular design allows seamless integration with various belt conveyors and production lines, offering flexible process layout configurations.
4. User-friendly operation with track movement controlled via handheld remote. The electrical control system features interlock protection, intuitive key operations, and PLC touchscreen interface.
5. Advanced technology and stable performance. The electronic control system features fault diagnosis capabilities, utilizing electro-hydraulic proportional control technology. It offers soft frequency conversion starts and adjustable deviation. Through rational energy matching, it achieves superior energy efficiency.
6. An electro-hydraulic dual-power interface is provided to facilitate peripheral operations such as material feeding, discharge transport, lighting, and hydraulic cylinder actuation.
7. Equipped with remote positioning and locking functions, the machine ensures precise positioning, reliable locking, and a high safety factor.
8. Features include video monitoring, signal transmission, wireless remote control, and more. Data recording enables comprehensive data analysis and fault diagnostics.
9. All machines are standardly motor-driven, with an optional hydraulic motor drive configuration available.
10. Customization is available to meet specific customer requirements.
Essential Tips for the Daily Use of Filter Presses1. How should the filter press be properly selected? Answer: First, determine the solid content of the wastewater. Solid content refers to the proportion of solids present in the wastewater. Additionally, you need to establish the daily volume of wastewater generated and the required working hours. Based on these factors, calculate the necessary processing capacity for the filter press, which then allows you to specify the appropriate chamber volume and filtration area. This approach ensures the easy selection of a…

5 Common Faults of Sand Washing MachinesThe sand washing machine is an essential piece of production equipment in the manufactured sand production line. Its primary function is to remove soil and dust from the surface of the sand, ensuring that the manufactured sand meets standard construction requirements. However, prolonged use inevitably leads to potential failures. Below are five common causes of failure for sand washing machines, along with their solutions. 1. Sand Washing Machine Shaft Breakage There are two main reasons for shaft breakage in sand…
What Are the Key Factors Affecting Sand-Making Machine Vibration?The rotor is the core component of the impact sand-making machine. If the rotor vibrates for any reason, it may cause vibration throughout the entire equipment. Therefore, we first introduce the causes of rotor vibration. 1. Misalignment between the motor shaft and the rotor shaft The solution is to realign the components. After inspecting the installation, ensure that the motor shaft and the rotor shaft are concentric. 2. Damaged rotor bearing If the bearing clearance exceeds the allowable limit or…
