It is one of the key suppliers of the ongoing Bullet Train and Surat Metro Rail Projects. The Mumbai – Ahmedabad High-Speed Rail (MAHSR Bullet Train) project is a 508.17 km High-Speed Rail line planned to connect Mumbai (Maharashtra) with Ahmedabad (Gujarat) through 12 stations.
Surat Metro with 2 lines and 37 stations is a mass rapid transit system (MRTS) built to serve Surat, the second largest city in Gujarat, by the Gujarat Metro Rail Corporation (GMRC).
Wanting to transition from the earlier installed air classifier, Patel Aggregates decided to go with CDE Asia’s patented technology, which has a legacy of providing high quality, washed Manufactured Sand and is a pioneer in comprehensive sand solutions for more than 15 years.
Understandably, both projects required a huge and consistent supply of M-Sand of Zone II grade. Being a decade-old CDE Asia customer, Patel Aggregates was aware of CDE Asia’s advanced equipment technology which assures superior M-Sand delivery with operational economy. Patel Aggregates approached the company with its requirement of a high feed capacity sand-washing plant that would be tailor-made to meet the demands of the two ongoing projects.

CDE Asia’s Combo X150: Powered by advanced European technology
After a series of detailed discussions and developing an understanding of the client’s specific requirements, the CDE Asia officials introduced their latest innovation in the Combo line of sand washing equipment – the Combo X150 (150 TPH) for producing the finest quality M-Sand.
Combo X150 is equipped for feeding, grading, dewatering, water recycling, conveying, and sludge handling. The plant can produce consistently graded M-sand with a high silt removal capacity of 15%. It has an impressive feed capacity of 150 TPH, 95% water recycling capacity, and up to 30% energy conservation capabilities. Combo X150 can operate for more than 18 hours a day and has a compact design requiring a significantly lesser geographical area to install. The plant is an ideal solution for saving the overall cement consumption in construction.
Powered by advanced European technology – Combo X150 can efficiently process the VSI dust from crushing operations to produce quality concrete M-Sand (Zone II), thereby adding to the client’s top-line profits. Along with a low energy requirement per ton of feed and a dust-free system, Combo X150 has a total noise output below 80db.
Witnessing and examining one of the existing CDE plants in action in Chikhli further cemented Patel Aggregates’ faith in the high-end technology and quality of the sand output of CDE Asia. The Combo X150 plant was finally commissioned on April 2022 and has continued to perform as a high-functioning system, producing an abundant amount of consistent quality sand for the client’s upcoming projects in Gujarat.

Reciprocating the accolades, Nitin Dubey, Chief Revenue Officer, CDE Asia, said, “We are constantly reinventing ourselves to renew the trust and faith that clients like Patel Aggregates LLP have placed in us over the years. Installing one of our latest innovations – the Combo X150 - was a welcome opportunity to put to test its comprehensive potential to manage a high volume of feed and produce quality output, while maintaining a low carbon footprint and optimizing profit for the client in terms of operation and energy costs. We are proud that the Combo line of products continues to live up to expectations.”
To date, the plant has run for more than 800 hours and produced a total of 80,000 MT of sand.
