The best equipment of ore dressing, equipment, which has, to be sorted process stabilization, is easy to control, and feed ore concentration allows variation range big, concentration ratio height,
The rate of recovery is high, the work characteristics of spiral chute be the end in slot intercept respectively essence, in, tailing, and during sorting not
Add flushing water；
It mainly contains in the concentrate that gravity treatment goes out in this step containing garnet；Mainly contain omphacite in chats, it is main in tailing
Contain the sundries such as silt, Mai Shi；
(4) concentrate is sent into spiral classifier and carries out classification gravity concentration, be carried out continuously classification gravity concentration three times, classification gravity concentration can produce
Raw rough and thin mine, what is obtained is rough, as the finished product mine containing garnet, and obtained thin mine is re-fed into spiral chute progress
Gravity treatment, gravity treatment can obtain rough and tailing, and gravity treatment is obtained rough, then sieved with high frequency vibrating fine screen, and screening can obtain
Rough and thin mine, that sieves is rough, as the finished product mine containing garnet, the thin mine discharge sieved；Gravity treatment is surplus
Under tailing discharge；
Spiral classifier is one of equipment of ore dressing, and spiral classifier is different by the specific gravity of solid particle, thus in a liquid
The different principle of the speed of precipitating carries out a kind of equipment of mechanical classification, for repeatedly being divided the concentrate containing garnet
Grade gravity treatment, guarantees the purity of finished product mine；
High frequency vibrating fine screen is to drive screen frame to move in a straight line by the opposite electrical vibrator of two directions of motion, two electrical vibrators
It is applied to center of gravity of the resultant force on screen frame by screen frame, the exciting force of each point is in the same size on screen frame, and processing capacity is big, screening is imitated
Rate is high, convenient for going out thin mine screen；Sift out it is rough can be filtered by Water filtration device for filtering, the water wherein contained is filtered out；
(5) chats is re-fed into spiral chute and carries out gravity treatment again, obtain secondary concentrate, secondary chats and secondary tailing,
After secondary concentrate is re-fed into the mixing of concentrate, classification gravity concentration is carried out by spiral classifier, secondary concentrate can directly and once
Concentrate mixing carries out gravity treatment, can also be mixed with the concentrate after a gravity treatment, then carry out gravity treatment, guarantees gravity treatment quality；
Chats is to mainly contain omphacite, and the sundries such as silt, Mai Shi are mainly contained in tailing；
Concentrate in step (4), is sent into spiral classifier and carried out by washing and screening plant efficient for above-described garnet
Classification gravity concentration three times；Step (5) mixes a chats with a concentrate in step (4) after scalping gravity treatment, then connects
Continue classification gravity concentration twice with a concentrate.
(6) tailing is discharged, the tailing that gravity treatment obtains in a tailing, secondary tailing and step (4) is arranged together
It out, is all containing sundries such as silt, Mai Shi.
The sorting that the technique whole process has water flow to participate in garnet substantially, water flow both play auxiliary raw ore and move
Dynamic, cleaning effect, it is often more important that by the effect of the gravity and centrifugal force of water flow eddy flow, Jiang Kuang is separated with sand, reaches choosing
The purpose of mine；The finished product mine containing garnet of output, it is subsequent to dry there is also certain humidity, then carry out more high-precision
The sorting of degree.
