CDE Asia’s pioneering Quartz Washing technology successfully installed in Rajasthan

In September 2020, CDE Asia broke new ground in quartz washing when it installed a customized Combo plant (Combo Exo) to help its client Goyal Group of Minerals achieve economies of cost and control over their quartz beneficiation and gradation process.

Since 2018, the thought of adopting a better washing, beneficiation and gradation system for their quartz plant had been playing on the minds of the owners of Goyal Group of Minerals. As one of India’s largest quartz mine owners, the cost of labour and overuse of water were failing to match up with the quality of output being produced. The rudimentary dry screening and washing system that was in place at the time was not only extremely labour intensive, but also not thorough with the washing of quartz lumps.

With no means to recycle water, wastage was at its maximum, and the abrasive quality of the lumps was routinely damaging the system, making it dysfunctional, especially during the monsoons. Reportedly, attempts to convert -5mm dust to M-Sand had also failed.

As Bijendra Goyal, CEO, Balaji Quartz, puts it, “Before our fortunate encounter with CDE Asia’s cutting-edge Combo Exo washing technology, we were struggling with issues of both cost and quality. Our installed washing system was dysfunctional on many levels and leading to extremely high running costs. We were routinely unsatisfied with the inefficient washing and removal of fines, the low TPH, high wear and tear, and overall unsatisfactory beneficiation that led to low market value of the output product.”

Bijendra Goyal was looking to enhance dust removal from quartz lumps, thus increasing their grade; segregate the output into different sizes according to industry standards, and increase the production of snow white quartz - all of which required truly innovative and customized technology.

Since it was one of CDE Asia’s early encounters with quartz washing, the company ran rigorous lab tests with different grades of quartz particles, and thereby earned his trust with a preliminary understanding of CDE’s revolutionary washing technologies, before introducing Combo Exo.

Combo Exo from CDE Asia is a superior washing and beneficiation system that keeps in mind both the quality of output and the client’s profit margins by economizing manpower, recycling water, increasing production capacity, and providing multiple grades as well as types of industry-ready products from a single, easy-to-install plant.

Commented a highly pleased Nakul Goyal, Director, Balaji Quartz, on the performance, “We have a lot of quartz stock, and with this plant, we are getting more recovery. Not only are we getting different industrial grades, but also the material that was earlier considered wastage is now being converted to M-Sand. So, this is a zero-wastage plant!”

Key benefits from the plant:

• Higher Yield: Increase in production from 70-80 TPD to 300-350 TPD
• Efficient washing: Attrition wash box which helps to liberate the dust from the surface of quartz lumps
• Size segregation: Product 1 – +25mm to -80mm; Product 2 – +5mm to -25mm; Product 3 – +0.075mm to +5mm
• Market diversification: Able to produce washed quartz (Quartz industry) as well as M-Sand (Construction industry) from the same plant
• Eco friendly: Zero effluent discharge
• Economy of cost:
• Minimizes water wastage with a water recycling system
• Fully automatic and therefore saves labour cost
• Compact plant is easy to install and takes up significantly less space
• Lesser downtime and maintenance costs due to superior build and minimum wear and tear
• Low power consumption
• Superior sludge management solution

The Combo Exo was launched on Sept 17, 2020, and soon after, handed over to Balaji Quartz. Since then, CDE Asia has received very good reviews from Balaji Quartz on the breakthrough washing technology that has resolved many of their long-standing problems, so much so that the company is keen to invest in a new plant with a little customization and a higher running capacity of 50-60TPH.

Said Niraj Goyal, “The Combo Exo from CDE Asia is the only quartz washing plant in India and so far, it has delivered on all its promises. I would recommend it to all my colleagues, partners, friends and even competitors in the industry for their material washing requirements.”

The CDE Asia team expresses its deepest gratitude to the Goyal Group of Minerals for this opportunity.
