MINETEK OUTPERFORMS STANDARD FAN BY ALMOST x7

Cadia, NSW, Australia
CADIA, NSW, AUSTRALIA

Given:
Newcrest Cadia mine approached MINETEK to provide a fan suitable for extracting dust caused from the dumping and crushing process underground. MINETEK provided a custom ventilation solution for this underground crusher.

 

Challenge:
The high abrasion rates caused by the airborne dust passing through the ventilation fans has caused rapid degradation of the incumbent vane axial ventilation fans.

With the current standard operation, the 110kW Single stage axial fans in use have an operating life span of 6-12 weeks, until the impeller has degraded and worn too significantly to be operably effective.

 

Solution and Results:
MINETEK proposed a 90kW High Output (HO) axial flow fan as a more suitable option, to provide both the required duty and longevity of performance and operation.

 

“Not only have we designed a fan that outperforms the existing axial fan, but we have also supplied one that is quieter and smaller, with a unique design that allows the dust to travel through the equipment with minimal impact to the structure.”– Jeremy Sutherland, MINETEK AIR

 

The fans were tested in a side by side comparison for three (3) months.

The MINETEK fan was estimated to last almost 7 times longer than the standard fan, with the robust steel impeller design able to withstand even the toughest environments without loss of performance.

The mine site ordered five MINETEK fans in total at the completion of this trial.

GOLDFIELDS, WA, AUSTRALIA

Given:

The customer aimed to increase production and expand exploration. Debottlenecking the existing primary ventilation circuit was required to achieve their goal.

Challenge:

MINETEK were commissioned to develop a primary booster fan of a size and technology combination not seen before in Australia. The full scope also included removal of redundant equipment and installation of the new fans.

 

Solution and Results:

MINETEK staff worked around the clock to ensure project goals were achieved within the tight timeframe, and managed to remove the old equipment, install the new fans and commission them in four days. 

Due to their size, for the fans to be tested prior to shipping, approval had to be granted from the Power Supply Authorities, and all other facilities in the MINETEK complex had to be shutdown to provide enough power.

 

Key Features of the fans:

  • POD: “Performance on Demand” vane inlet controls to adjust vent flow and power usage.
  • Impulse bladed impeller equipment with an anti-stall chamber to ensure optimum fan performance.
  • 1100kW/1000V individual fan motors (all run off the renewable power station).
  • 280m³/sec @ 3700Pa for current production needs with a maximum airflow capability of 350m³/sec @ 4200kPa.

HIGH PERFORMANCE UNDERGROUND

Tritton, NSW, Australia
TRITTON, NSW AUSTRALIA

Given:

Tritton Mine continued drilling to the deposit, at a depth of up to 1,500m below the surface.

 

Challenge:
The site needed ventilation to the bottom of the drilling extension and faced a difficult and costly installation process of using traditional fans, due to the power and pressure needed to meet the required duty point.

 

Solution and Results:

MINETEK proposed one 375kW auxiliary High Output (H.O) Axial Fan that included integrated Performance on Demand (POD) system, soft starter, and programmable logic controller.

 

The single fan install prevented multiple duct runs, and had additional benefits such as faster re-entry times and power saving. This is due to the ability to ramp up or down the air pressure as needed.

AIR CAPABILITIES

Primary Ventilation Fans

MINETEK can supply the largest available fans for main fan ventilation. Innovative engineering and premier quality have resulted in world first features like MINETEK’s Performance on Demand (POD) controls. Experience power saving, durability and flexibility not achieved with traditional fans.

Secondary/Auxilliary Fans

Keep additional fan installations and mid-project shutdowns to a minimum, with MINETEK’s auxilliary fans. Compact in size , while the high pressure capability results in less fans needed for the development. Benefit from automation, syncronisation and control from the surface.

Booster Fans

Strategically optimise underground air flow with MINETEK. Use primary booster fans for both return and intake airways and benefit from all the MINETEK advantages. MINETEK’s fans can sequence with the main ventilation. The anti-stall feature makes it a reliable choice for booster ventilation.

Multiple Heading Ventilation

Use one fan instead of many, by using MINETEK for multiple heading ventilation. Reduce operating costs, decrease requirements for installation, and get MAC controlled ventilation with MINETEK’s high output fans.

Bulkhead Fans

Synchronise bulkhead fans with MINETEK’s Performance On Demand (POD) and Mine Air Control (MAC) system. Halve the amount of fans required, and stop inefficient power wastage, stalling and duct friction with MINETEK.

Long Duct Runs

The concentrated power of MINETEK’s High Output (HO) Axial Fans, makes them the ideal solution for long duct runs. With more than twice the pressure capacity of a standard bladed axial fan, less fans are needed throughout the development.

Tunnel Fans

MINETEK’s low profile fan provides additional clearance between ventilation ducts and loaded vehicles, making them the ideal solution for tunnels. Improve safety, save power, and achieve maximum performance with MINETEK.

Development Fans

Utilise MINETEK’s Pressure, Power, Performance on Demand (POD) system throughout development and reap the economic benefits. Control from the surface, and only use the air pressure and power you need at each stage of the development. MINETEK’s fans will grow with your project.

Mine Air Control (MAC)

The Mine Air Control (MAC) system, in conjunction with the fans Performance on Demand (POD) technology enables synchronization of both the primary and secondary ventilation fans to increased performance, economic benefits, and efficient use of power. Control the ventilation system remotely for ideal performance from the surface.

VISION, INNOVATION & RESULTS

MINETEK’s experience and innovative technology helps us solve difficult ventilation solutions across the world.



No other fan can compete with MINETEK’s forward-thinking technology. The steel bladed impeller, smooth functionality and seamless integration with automated features, make MINETEK a world leader in improving ventilation conditions.
