Pulp and Paper

 Black Rock’s team of engineers, designers and programmers are comfortable designing and programming paper’s specialized equipment and processes.

Paper Machine Specialists

We have experience with:

  • Rollers, and roller drive systems
  • Paper winder machines
  • Paper machine controls
  • Storage tanks
  • Boilers and Pressure vessels
  • Conveyance and treatment systems
  • Pumping and piping of liquids and slurries
  • Capital and operating cost estimates
  • Lifting and transportation systems
  • Design and selection of power transmission equipment such as: gearboxes, brakes, clutches, anti-friction bearings, hydrodynamic bearings, couplings, backstop, speed variator and transmissions, VFDs
Specialty Control Systems

We program most standard PLCs and HMIs, but we can also provide some very specific applications, such as the stone detector that we developed for one paper mill. It measured for changes in the ambient sound to identify stones on the conveyor entering the xxx.

Maintenance and Analysis

We provide maintenance engineering and/or analysis for paper equipment, including:

  • Preventive and predictive maintenance
  • Repair and replacement recommendations and design
  • Stress and fatigue analysis for all components listed above (FEA)
  • Vibration and noise
  • Machine safety
  • Energy
