Client: PCS Potash, Cory Division, Saskatoon,
ENGCOMP was commissioned by the Potash Corporation
of Saskatchewan - Cory Division (PCS Cory) to provide cost estimating,
scheduling, and detailed engineering services for the installation
of a new screen in their existing Loadout facility. This new screen
was to replace their existing classification system for the sizing
of their prill and granular products. A more efficient system
would lead to an increased capacity for loading product, less
horsepower usage, and the opportunity for future expansion.

This project provided both engineering and logistical
challenges. ENGCOMP provided support in assisting the client in
selecting a suitable screen and then proceeded to provide engineering
services for the installation of this screen. The installation
involved demolishing existing structural steel and mechanical
components in the area and installing new structural steel and
mechanical components within the existing area to support the
ENGCOMP worked closely with the client and the
screen manufacturer in order to produce a suitable design that
satisfied current demands as well as provide an opportunity for
the client to expand this area of their operation in the future.
- PCS Cory was using a classifier and single-deck
screen arrangement to size prill and granular product being
reclaimed from the warehouses at a maximum rate of 400 MTPH
- This system existed in their Loadout Dispatch
facility and took up a substantial amount of space. There were
two classifiers, and each one was approximately 25 feet in diameter
and 22 feet tall. For each classifier there were additional
components including blowers, quad cyclone packs, hoppers, and
- The ductwork that went into and came out
of the classifiers had been packed with material over time such
that the classifiers were not operating efficiently.
- The client planned to install a new high-capacity
screening machine within their existing Loadout Dispatch facility
to take the place of the existing two-classifier system for
cleaning Prill and Granular products being reclaimed from warehouse
- The new screen will increase the efficiency
of product separating, increase the overall capacity of the
system, and decrease the amount of horsepower needed to power
that particular area of the plant.
- The removal of the classifiers and related
equipment will also open up the area for future expansion and
better access for maintenance.
- The design process included the use of 3D
parametric CAD modeling to determine a suitable location among
all the existing steel and equipment for the screen and the
location of all structural steel and mechanical components necessary
for the new addition.
- Increase the speed of the current sizing
process from 400 MTPH (metric tonnes per hour) to 600 MTPH.
- Design new chutes that are "gravity
fed" for which no additional mechanical conveyance is required
to move the product streams.
- Design new structural steel and mechanical
equipment to be installed in an existing area of the plant.
- Ensure that all new components interact safely
and efficiently with existing components in the area.
- $2.4 million
- Project was awarded to ENGCOMP in February
- Project is scheduled for completion in January
- PCS Cory is satisfied with the progression
of this project.
- ENGCOMP continues to work closely with the
client to ensure a successful installation.
