Product Introduction:
The process is a common processing technology for wet process glass sand.firstly, Quartz fall under the hopper,quartz stone is broken into the coarse material after primary crushing, and be transported by belt conveyor for further crushing to the second crushing machine, then the smaller stone will be taken into the vibrating screen for screening out two type size quartz stones, exceed size stone will be returned to crushing machine again.
Sieved material into the rod milling machine, Materials from the rod milling machine to classify through the cylinder screen. in the sieve to return to the rod milling machine, Sieved material to eliminate the tramp iron by high intensity magnetic separator, and then into the Vertical Ring High Gradient Magnetic Separator to remove the residual mechanical iron and associated iron , usually after two procedures of separating, quartz sand iron content can down to below 0.07%,
Finally ,the qualified pulp through the hydraulic desliming slot to take off the mud, and then dehydrated to become the qualified quartz sand products. In the production line, Rod mill and the High Gradient Magnetic Separator is one of the core equipment, this production line is a high degree of automation, low operation cost, high crushing efficiency, energy saving, large output, less pollution, easy maintenance, the final quartz sand has the uniform size, good grain shape and reasonable size distribution ,which can meet the national standards of construction machine-made sand.
Application scope:
Quartz, feldspar, beryl, etc
Advantages:
1. Mature technology, energy conservation and environmental protection! High purity without pollution. Adopting reasonable technological equipment, it can save power consumption and realize zero discharge of sewage and dust.
2. The equipment is simple to operate and highly automatic. The production line is elaborately designed with advanced circuit control system, which not only saves manpower but also lowers the operating threshold of the production line.
3. Large output, uniform product particle size and higher sand forming rate, the whole production process is graded by cylinder screen, blocking and classifier for many times, which not only improves the efficiency of the production line, but also reduces the loss of raw ore and controls the content of tail powder.
4.High quality products can effectively reduce the content of quartz sand iron. We have rich experience in quartz sand production line. The whole process is not only equipped with advanced iron removal equipment, but also controlled at the source to reduce sand pollution in the process as much as possible.
Working principle:
General process flow is: Raw ore -- coarse crushing -- medium crushing -- pre-screening -- grinding -- desliming -- coarse grain classification -- desliming -- plate type magnetic separator -- high gradient vertical ring magnetic separator -- fine grain classification – dehydration. The process of wet quartz fine sand production.
The forklift truck feeds the raw ore into the hopper, and a conveyor is placed at the end of the silo. The raw ore from the tail is distributed to the jaw crusher (rough breaking) directly below through the conveyor and the vibration feeder, for preliminary crushing. After that, the crude material produced is transported from the conveyor to the fine crushing machine for further crushing. The fine stone material is put into the vibrating screen, and two kinds of stones and stones of different sizes are screened out. The material under the screen enters the rod mill. The material from the rod mill is sorted by the cylinder screen and returned to the rod mill on the screen. Material under the screen enters the hindered sedimentation machine and hydraulic classifier for classification. The finished product is removed by high field strength plate magnetic separator and high gradient vertical ring strong magnetic separator. The refined sand after iron removal is driven into the fine sand bank after dewatering by the dredge bucket.
