Understanding your new crushing and screening plant project criteria is very much a process and a collaborative exercise.  It is very common within a client’s organization to struggle while trying to achieve consensus and/or delineate common goals.  Optimizing capital cost and performance or plant output is the eternal challenge in today’s rock and mineral processing world. Our many decades of experience and ability to collaborate with your many stakeholders will help to ensure your goals are developed optimally and then achieved.

The 4 secrets to successfully expanding or building a crushing and screening plant with low unit operating costs are; 1) process flow sheet, 2) equipment selection, 3) design details, and 4) project management.  All four are equally important.

  1. Process flow sheet; impacting plant performance and product quality.
    Our partners have had decades of hands-on experience. We typically work closely with the crusher and vibrating screen manufacturers to ensure the process will achieve your plant performance goals.
  2. Equipment selection; also impacting plant performance goals and product quality.
    We are pleased to offer our opinions, but are more than happy to have you free-issue the main equipment components such as crushers and vibrating screens.
  3. Engineering: Design details; impacting mechanical availability and safety.
    The “devil is in the details”. Whitwick’s 30 years of experience in designing and engineering crushing & screening plants ensures that your plant unit operating costs will be the lowest possible.  Plant or mechanical availability is not only a function of operating and maintenance practices, but also of design!  For example, transfer points are key.  Well-designed points ensure reduced maintenance costs, less labor requirements, and they help to ensure a safe working environment.  We cannot emphasize the importance of design details enough.
  4. Project management; impacting capital costs, construction safety and schedules.
    Execution!  Both internal and site project management are equally important and will significantly impact the success of your project.  Once again, Whitwick’s many years of experience in building numerous types of plants and systems helps us to ensure schedules and budgets are achieved.  Their site managers are devoted to safety and schedules.
