Data
The sludge while turning performs a mixing which promotes
friction between particles; thus the latter will be freed from the gangue which
surrounds them during a trajectory; this movement corrupts in 3 stages:
I – The phosphate grains are joked by the longitudinal
lifting rails against the return current.
ii-They are driven by these rails in a movement against the
interior of the tumbler.
iii-And in a blade these particles fall towards the lower
part of the cylinder which causes the shock necessary for the grains to get rid
of the gangue which surrounds them.
C - Conveyor:
It is a transporter from one point to another
It is created from a mechanical bolster gathering.
There are two strands for conveyor:
1 - Lower strand.
2 - Upper strand.
D - Philippe filter:
It is located at the balance of chain 6 of the laundromat; it
is recently installed to replace the wringer. role is to separate the
phosphates from the filter under the action of a vacuum.
The Philippe filter is standard:
· A conveyor belt.
· A filter cloth.
· 4 washing ramps and a separating strip with barometric
footing.
· Driving head (coupled motor + motor).
· A tape pressure system.
· A separating strip with barometric footing.
WASHING CHAIN APPARATUS:
A - Cyclone:
A twister is a cylindrical unit in which the pulp is
injected tangentially by an injection base inside the violent wind. The pulp
takes a very rapid pivotal movement; the in addition to gros and the in
addition to dense are centrifuged and brought to the wall.
B - Sludge trap:
The first stage of phosphate washing separation is done in a
sludge trap which is a rotary drum carried and driven by standard tires.
