An evolution in comminution

When it comes to grinding, our HPGR is the right choice for energy-efficient comminution technology to meet the challenges of complex ores.

Whether it’s a new unit or an upgrade, let us take your grinding operations to the next level. 

Improving efficiency, reliability, and sustainability is on ongoing challenge in the mining industry. This is particularly so in the grinding circuit, where traditional solutions consume significant quantities of energy, water, and grinding media. 

 

In contrast, HGPR have long proved themselves to be the most energy-efficient form of comminution. And as a dry process that relies on compression between two counter-rotating rollers to crush the feed material, no water or grinding media are required.


These benefits have now been extended with the HGPR Pro, which offers up to 20% more throughput for up to 15% lower energy consumption. We have also extended roller life by up to 30% to create an ore grinding solution that is not only more economical than ever but is – quite simply – the best performing machine in its class.

Adding HPGR Pro to our comminution offerings

We are very excited to add the HPGR Pro to our comminution product portfolio. HGPR Pro incorporates a range of cutting-edge engineering and digital solutions that provide the basis for enhanced performance. Based on our experience in the field and conversations with numerous clients, these improvements represent unique advances to high-pressure grinding in the mining and minerals processing sector.  FLSmidth will not only be well positioned to supply the HPGR Pro, but also to service these machines, and others, over the life of the product.

Productive, sustainable comminution

Grinding even the most complex ores has never been easier; the benefits of high-pressure grinding, never more pronounced. HGPR Pro enables improved productivity, reliability, and product quality, at lower cost. This cutting-edge machine also comes with advanced digital functionality that enables continued process optimization and predictive maintenance. 

These benefits are available whatever your grinding needs. Whether it’s a new machine or upgrade, for an existing application or opening-up new uses for our tried-and-tested technology, we have the expertise to supply the right solution for you. 
 

Achieving best-in-class grinding performance

HGPR Pro incorporates a range of cutting-edge engineering and digital solutions that provide the basis for enhanced performance. Our new technology informs the operator of machine status and enables continual process optimization and predictive maintenance.

Rotating side-plates for a uniform pressure profile and improved even roll wear

Rotating side-plates are the key to the enhanced performance delivered by HGPR Pro. By improving material flow into the rollers, this innovative feature can improve throughput by up to 20%, reduces energy consumption by up to 15%, lowers maintenance requirements, and extends roll service life.

 Wear segments on the side-plates can be removed or adjusted without removing the rollers. This simplifies – and therefore speeds up – maintenance to reduce non-productive time.

Controlled skew limitation through mechanical locking device

This unique feature of the HGPR Pro comprises a mechanical locking device to limit misalignment of the moveable roller. It allows the rollers to adjust to feed conditions and maintain uniform pressure, while ensuring critical limits are not exceeded and protecting the rotating side-plates. The result is higher-quality product with fewer machine outages and downtime.

Lubrication with oil Instead of grease

Bearings are lubricated with a constant stream of conditioned oil. This enables higher machine loads to be achieved, as well as lowering bearing temperature. Oil is conditioned in a closed-loop circuit to remove impurities. This reduces lubricant consumption and maximizes service life of the bearings.

  • Longer-lasting bearings
  • Lower environmental impact
  • Reduced operating costs by decreased lubricant consumption
