Rhosonics heralds new era of slurry density measurements with SDM ECO

Rhosonics, a global leader in non-nuclear slurry density meters, has unveiled its third-generation product, the SDM ECO.

The SDM ECO is a significant advancement in slurry density measurement technology, according to the company, offering improved accuracy, reliability and user-friendliness.

The product preludes a new era of slurry density measurements, Rhosonics says.

The SDM ECO uses ultrasonic technology to measure the density of slurries in real time, without the use of hazardous radioactive materials. This makes it a safer and more cost-effective alternative to traditional radiometric density meters.

The Rhosonics density meter has a rugged design for continuous operation in harsh industrial environments. It is also ergonomic, which makes the SDM ECO easy to install and maintain, featuring a user-friendly interface and intuitive software.

The product offers multiple analogue and digital outputs. Settings can be changed remotely through a web server, without the need to install product-specific software. The use of an optional Wi-Fi module, meanwhile, allows the SDM ECO to be controlled using a mobile phone or tablet

The SDM ECO is ideal for a wide range of applications in mineral processing, dredging, tunneling and other industries. Furthermore, it can be used to monitor process stability and, when combined with a flow meter, can track the quantities of slurry being transferred to downstream processes. This, ultimately, contributes to optimising operational efficiency.

“The SDM ECO represents a significant advancement in slurry density measurement technology,” Vitor Braz, Global Sales Manager at Rhosonics, said. “With its improved accuracy, reliability, and user-friendliness, we are confident that the SDM ECO will become the new benchmark for slurry density meters in the market.”

Rhosonics to launch new non-nuclear slurry density meter next month

Rhosonics is set to launch its new non-nuclear density meter, the ‘SDM ECO’, next month as part of an online event.

Back in 2004, Rhosonics says it was pioneering the use of ultrasonics as an alternative to radiometric technologies for slurry density measurements. The first tests were done at the beginning of this millennium and resulted in the Rhosonics density meter 9600 series, introduced in 2008. Valuable field experience was gained and incorporated into the second-generation density meter that was introduced under the name ‘SDM’ in 2016. According to Rhosonics, this product has become the fastest-growing alternative to conventional radiometric density meters so far. It has taken up the task of improving the operational efficiency of many mineral processing sites worldwide reaching over 300 installations anually in recent years as stated by the company.

The SDM Slurry Density Meter, also refered to as ‘SDM-4’, will be discontinued and replaced by its successor ‘SDM ECO’. The SDM-4 will be sold until January 2024 and, after that date, Rhosonics is keeping a limited stock available for a five-year support plan.

The company said: “Measuring the slurry density is crucial in many applications in industries such as mining & metals, dredging, tunneling and other construction works, and in new segments such as battery production and metal recycling. The slurry density meter can be applied to monitor the process stability and can be combined with a flow meter to track the quantities of slurry that is being transferred to downstream processes. Additionally, the measurement data can be used to optimise the operational efficiency throughout the plant.”

Vitor Braz, Global Sales Manager at Rhosonics, added: “We are currently leading the non-nuclear slurry density meters segment and are about to launch our third generation product that incorporates the lessons learned from the last two decades. We will set a new benchmark for competitors and usher in a new era for slurry density measurements.

“The SDM ECO will become our new flagship product to help different industries achieve operational excellence without using hazardous radioactive materials. This field-proven product will offer reliable readings while having clear advantages in terms of safety and product lifetime costs compared to radiometric instruments.”

Rhosonics SDMs win plaudits at OCP Group’s Beni Amir phosphate mine

Rhosonics Slurry Density Meter (SDM) has proven its worth at the OCP Group’s Beni Amir phosphate mine and washing plant in Morocco, the Netherlands-based company said in its latest case study.

The leading phosphate miner recently evaluated nine months’ worth of test work at Beni Amir, which came out with favourable results.

OCP began operating the Beni Amir mine and washing plant in Morocco in 2015. Here, the phosphate ore at the washing plant goes through a wet treatment process to enrich the ore and increase its “Boone Phosphate of Line” content, according to Rhosonics.

Four pieces of the Rhosonics SDM, a non-nuclear density meter using sustainable ultrasonic technology, were installed at the Beni Amir plant in April 2018.

Rhosonics said: “The phosphate industry traditionally uses nuclear devices. Non-nuclear devices are still quite new to this industry and success stories are limited.”

By measuring the acoustic impedance of a slurry, the SDM calculates the density of the slurry in-line during the process, according to Rhosconics. The sensor is made of stainless steel and ceramic material. “Because of the new sensor material, the sensor has lots of better properties. By making use of ceramic material, the ultrasonic signal is more bright and powerful than before.”

Mohammed el Moudden, Chief Instrumentation of OCP Beni Amir, said: “We confirm a successful test of the SDM from April 2018 until now. A single calibration is sufficient for operation over three months. The team at the Beni Amir washing plant are satisfied with this technology.”

The Rhosonics SDMs were installed in the output of a cyclone, a mixing tank and two thickeners to improve the efficiency and fully use the production capacity of these separation processes, Rhosonics said.

Now, following this trial, the OCP Group has bought 13 additional non-nuclear Rhosonics SDMs to install at several locations at the washing plant, the company said.
