Pulp and Paper Machine Technical Audits

As part of the drive to increase production, lower costs or improve products, Sandwell is often asked to participate in audits of pulp or paper machines. Such reviews are an essential first step in defining the scope and cost of a capital project.

The Objectives

Technical audits may be undertaken to:

  • assess the condition of a machine and its auxiliary systems
  • locate and solve a problem
  • identify speed, efficiency and product range limitations
  • prepare a capital investment plan
  • re-evaluate the product line.
