CDE Asia’s Integrated Mobile Washing Plant for Superior M-Sand Production
A larger version of the flagship X70 model, the Combo™ X150 cleans, grades and recycles up to 95% of water in one machine, and can produce concrete and plaster sand simultaneously.
Developed specifically for the manufactured sand (m-sand) washing market, CDE Asia’s Combo™ X150 washing system integrates all washing processes from end-to-end on a single compact mobile unit. The plant, with its patented cutting-edge technology, gives accurate control of silt cut points to deliver high-quality sand. The plant not only maximises the production of m-sand but also reduces water consumption by up to 95%. The new Combo™ X150 incorporates a water management system, making it extremely eco-friendly. The integrated water recycling and sludge management capability enable the plant to be deployed in areas where traditional sand washing systems cannot be used, as large volumes of water and land are often required to operate the equipment.
An Eco-Friendly Sand Washing System
The patented* CDE Combo™ all-in-one wet processing system only requires a small supply of fresh water in comparison to traditional systems which typically consume up to 15 times more water. Manish Bhartia, Managing Director, CDE Asia explains, "This is what makes the Combo the most eco-friendly sand washing system in the world. The other significant advantage is the low power consumption of 0.85kW per tonne of feed - at just 170 kW maximum power rating – which makes the Combo™ X150 the most power-efficient machine using clean energy. Our innovations demonstrate CDE Asia’s commitment to help customers achieve the highest sand specifications, using washing technologies, while ensuring minimum impact on our environment."
An intelligent remote monitoring platform is also on board the Combo™ X150, as an option. It enables real-time measurement of critical functions, storage of equipment-usage data for accurate diagnosis during service calls, and broadcast of user warnings for service requirement. It assists users in getting maximum plant performance with maximum equipment availability, allowing customers to meet and exceed their production targets.
Manish Bhartia continues: "The Combo™ X150, with its production capacity of 150-200 tonnes per hour, provides an attractive proposition to the maturing washed m-sand market in India, and is now available in over 10 countries in Asia. In fact, our washed m-sand is a preferred choice as it is a viable alternative to river sand. With the spurt in construction projects, larger companies are regularly demanding high capacity plants meet their sand requirement. The Combo™ X150 provides the perfect solution in meeting their need for an integrated mobile wash system that maximises water use. This also gives operators the flexibility to produce concrete or plaster sand simultaneously, from one machine."
The Modular Benefits
The Combo™ X150 all-in-one wet processing system can be applied for washing a wide range of materials including m-sand, crushed rock fines, natural sand, and gravel. Due to its modular design, the need for lengthy civil and structural work is greatly reduced, while the associated time-consuming process of dismantling and reinstalling the plant is also significantly reduced. Companies engaged in quarrying in different geographic locations can move the Combo™ X150 plant as per their requirement, while the plant itself can be commissioned on site in less than 7 days.
A feeding system puts the feed material into the washing unit, which removes more than -75 microns fraction from the feed material. The material is then forwarded to the dewatering unit, which delivers washed, dewatered, and well-graded sand products of two grades of concrete and plaster sand via an integrated stockpile of conveyors. Waste water from the system is transferred to the inbuilt recycling unit, where the solids are separated from the water. The recycled water is circulated back into the plant and the final waste silt is removed from the recycling unit in the form of concentrated sludge for easy recovery through the integrated EasySettle sludge management system. The technology to convert sludge into light-weight bricks for construction use is also provided by the CDETechCenter.
A New World of Resource
The new mobile Combo™ X150 was invented at the company’s R&D centre. CDE Asia has created this entirely new marketplace across Asia with over 300 installations spread over 10 countries. “Our eco-friendly technology of producing washed and graded manufactured sand is helping developing economies to reduce their reliance on natural sand, which is fast becoming scarce and expensive. It has benefitted construction companies by providing top quality graded construction sand and sustainable operations. By utilising normally low-value crusher fines for sand production, we can extend the life of natural resources and also add huge commercial value to our customers’ enterprises,” concludes Mr. Bhartia, Managing Director of CDE Asia.
