CRUSHING
Name the crushing force: Material breaks through natural fault lines and weak spots by colliding with hammers or ‘picks’ fixed to a spinning rotor.
Impact
Fill in the blank: Potash processing uses both ______ and ______ screening.
Wet and dry
Conditioning and flotation equipment is only used within the ______ processing stage.
Wet
The centrifuge and drying equipment removes as much ______ as possible.
Brine
TMA stands for _________ _________ ______.
Tailings Management Area
Name the crushing force: Material is squeezed between one stationary and one mobile surface.
Compression
Fill in the blank: Sizing equipment can be used to separate particles by size, shape, or _________.
Density
_________ _________ are the only conditioning and flotation equipment that use mechanical force.
Attrition scrubbers
If the temperature of potash remains too high following the dryer process, it becomes extremely hard. This is known as _________.
_________ are the first unit operation in this process and the last chance to remove KCl before tailings.
Cyclones
Name the crushing force: Material is held in place and trimmed to the right size and shape by contact with a tool or other hard surface.
Shearing
Fill in the blank: _________ press potash fines together to make a large sheet (known as flake).
Compactor/Force Feeder
Conditioning equipment used in potash processing separates the _________ from the _________.
Overflow, underflow
_________ is the force that helps material maintain its hydraulic characteristics.
Fluidization
_________ use mechanical force and gravity to clarify the brine of solids so fluid can be reused and the waste sent to tailings.
Thickeners
Name the crusher type: Rotating hammers or blow bars strike the ore and throw it against the impact aprons, breaking it into smaller pieces.
Impact crusher
Fill in the blank: A DSM (Dutch State Mines) screen is another name for a _________ _________ screen.
Sieve bend
In a conditioner drum, the particles become _________.
Hydrophobic
The _________ dryer/cooler heats and cools the product in one step.
Glazing
The ______ _________ concentrates and recycles brine solution by removing excess water.
Salt thickener
Name the crusher type: The two upper rollers break lumps or large material into smaller, uniform pieces. These pieces are then fed into the lower rollers, which crush the material to the required product size.
Flake breaker
Fill in the blank: The _________ ______ _________ contains balls that bounce around during operation to prevent ‘blinding’.
Stacked bed screen
_________ ______ separate the hydrophilic particles from the hydrophobic particles.
Flotation cells
In the centrifuge, ______ move to the bowl wall and ______ remain in the centre.
Solids, liquid
The _________ _________ clarifies brine of fine particles so fluid can be reused and waste slurry material sent to tailings.
Slimes thickener
