40m3/s Mobile, Hybrid, Track Dust Collector

JMS-40-MHT. Overview.

The JMS-40-MHT (Mobile, Hybrid, Track) is a complete dust collection system mounted on a compact, track base. It features a dirty air intake, filter house, clean air box, silencer, exhaust, dust discharge system and centrifugal fan to create 40m3/s (85,000CFM) @ -3kPa.*

Efficiency. Power.
One of the key features of the JMS-40-MHT is the inclusion of a Variable Speed Drive (VSD) as part of the standard configuration. The VSD ensures the dust collector provides the required air flow using the least amount of power. If there is insufficient air flow, the air flow meter on the dust collector will turn up the Variable Speed Drive (VSD) to generate more air volume. Equally the air flow meter will turn down the VSD so the dust collector uses less kW for the same amount of volume depending on the temperature and conditions. This makes the units power efficient, and clients have reported they have been able to reduce their power consumption by up to 40%.

Investment Options. Purchase (New & Refurbished) or Rental.

We have new and refurbished units available for purchase, along with JMS-40-MHT units in our rental fleet to provide short-medium-long-term hire.

Mobility. Track Mounted.

The JMS-40-MHT is mounted on a track undercarriage to offer full mobility and better control with variable speeds between 2–4 km/h to increase the speed and efficiency of operations.

Grydale hold the patent for manufacturing the only self propelled, mobile dust collection units on the market. Our track mounted units have 4 key advantages:

  1. Units can be easily transported and operational in a very short period, with limited set-up requirements.
  2. The diesel motor powering the fan means there is no requirement for an external power supply, such as a mains connection or auxiliary power units.
  3. Units can be easily moved during operation. Moving alongside dust generating equipment, such as road headers and machines used for bench excavation and cross passages provides effective dust collection at source.
  4. Units do not require long, expensive ducting to be constructed/installed.
  5. Units offer full mobility and better control with variable speeds between 2–4 kph to increase the speed and efficiency of operations.

Power. Hybrid (Electric 415V or 1000V and T4/T5 Diesel Engine).

The JMS-40-MHT (Mobile, Hybrid, Track) uses 380-480V or 1000V electric to power the centrifugal exhaust fan, auger, rotary valve discharge system and screw compressor. The tracks are hydraulically powered by the T4F/5 diesel engine and operated via remote control. (Umbilical control is also provided as a failsafe.)
