In underground engineering operations such as pile foundation construction, shield tunneling, and non excavation pipe jacking, mud carries a large amount of solid impurities such as sand and gravel. If directly recycled, it is highly prone to wear and tear on pump bodies, pipelines, and drilling tools, greatly shortening the service life of equipment and causing engineering hazards such as mud performance imbalance and construction collapse. The Desander, also commonly known as the mud sand remover, is a core specialized equipment in the mud purification treatment system. It can quickly separate solid particles of coarse and fine sand from the mud, purify and recover usable mud, achieve mud recycling and centralized discharge of waste residue, and is an indispensable supporting equipment for geotechnical engineering construction.
The core of the Desander relies on a dual process of hydraulic cyclone classification and multi-layer vibration screening to achieve solid-liquid separation: the slurry is pressurized by a slurry pump and sent to the cyclone, where high-density sand particles settle and are discharged downwards under centrifugal force, and lightweight slurry flows back upwards; The residual mixed sand mud enters the upper fine screen, lower coarse screen, and back screen multi-stage polyurethane vibrating screen, screening and intercepting different particle sizes of sand and gravel layer by layer, and the clean mud is re circulated in the mud pit for reuse. The entire equipment is integrated with a swirl device, vibration motor, feed slurry pump, and slurry storage box, with a compact structure that can be flexibly transported and installed on the construction site. It operates automatically and continuously without the need for manual cleaning of soil, greatly reducing on-site labor costs.
SINOVO GROUP is deeply engaged in the research and manufacturing of engineering mud purification equipment, with multiple standardized Desander products that can adapt to different construction volumes and mud processing requirements. The four main models have complete technical parameters, covering the entire scene of long-distance excavation from small and medium-sized pile foundations to large shield tunnels. The models include SD-100/30, SD-200/60, SD-250/60-20, SD-500/60-20.
Our entire range of Desander screening screens are made of wear-resistant polyurethane material, which has a longer service life for vulnerable parts; The vibration motor and slurry pump are equipped with mature power configurations, suitable for 380V industrial general power supply, with low equipment failure rate and simple operation and maintenance. The use of a Desander can not only reduce the procurement cost of raw materials for the preparation of new mud, but also greatly improve the recycling rate of mud. The centralized transportation of waste soil can also reduce environmental dust and mud discharge problems on site, balancing construction economy and green construction requirements.
Nowadays, mud purification has become a standardized requirement for engineering construction. Different construction scales correspond to the selection of exclusive models of Desanders. SINOVO’s full range of models fully covers various construction conditions and can provide one-stop mud solid-liquid separation solutions for geotechnical engineering customers at home and abroad.
