The spiral classifier is widely used to pregrading and inspection grading in closed circuits when used in the production flow of metal processing. According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 1.5mm-0.03mm are classified. Classification equipment---the spiral of overflow end is completely immersed below liquid level.
Its principle is to use the difference in the settling speed of solid particles in the liquid to classify materials. The classification effect of the spiral classifier will directly affect the content of qualified products in the returned …
The spiral classifier is a cornerstone in mineral processing, offering a reliable and cost-effective method for particle separation. Its simple design, versatility, and efficiency make it an essential piece of equipment for various applications, …
Common spiral classifiers can be classified according to the overflow height, that is, the position of the spiral in the water tank is different from the height of the pulp surface. The spiral classifier can be divided into three …
Spiral classifiers classify particles based on their size, ensuring that the desired particle size range is achieved in downstream processes. It is essential in ore grinding and beneficiation processes, where the particle size …
Spiral classifier is suitable for the flow ore sand in the beneficiation plant, the particle size classification of the ore pulp in the metal beneficiation process, and the desliming and dewatering operations in the ore washing operation. It is especially suitable for washing, grading, impurity removal, and fine-grained and coarse-grained material washing in water, electricity, …
Common spiral classifiers include high type and submerged type. The high type is usually used for coarse-grain classification, and the diameter of the overflow particle size of the classification is generally greater than 0.15mm. The submerged type is suitable for fine particle classification, and the overflow particl…
Spiral classifiers can be categorized into different types based on the design of the spiral blade and the trough. Each type is suited to specific applications: 3.1 High Dam Spiral Classifier. Design: The spiral blade extends above the slurry surface. Application: Ideal for separating coarse particles and used in rough grinding stages.
When gravity separates fluorite ore and scheelite, the difference in specific gravity between the two minerals must be considered. Fluorite has a relatively low specific gravity of about 3.2-3.3, while scheelite has a higher specific gravity of 5.9 to 6.1.
Fluorite ore beneficiation is a complex process involving various stages of extracting the fluorspar mineral from its original form. The process typically involves crushing, grinding and flotation methods to separate valuable fluorspar from other impurities. An interesting aspect of fluorspar ore beneficiation is the use of advanced technologies, such as gravity …
3. Limonite Flotation process. Limonite has a complex structure consisting of hydrated iron oxides. The flotation method is unique in its ability to selectively separate the desired minerals from the unwanted gangue material using surfactants, thereby improving the overall efficiency of ore processing. Flotation involves the addition of reagents to render …
This is a complete 15TPH fluorite flotation plant designed for a Pakistani customer. The main equipment and process details are as follows: Jaw crusher— Vibrating screen— Electromagnetic vibrating feeder— Ball mill— Spiral classifier— Conditioning tank— Flotation machine— Thickener— Slurry pump— Vacuum disk filter
1. Fluorite ore beneficiation. Fluorite ore beneficiation mainly adopts the flotation method and gravity separation method. The flotation method deals with fine-grained dissemination and low-grade fluorite ore. Flotation is one of …
The spiral classifier here uses double spirals by 1.5meters diameter, also can use single spiral by 2 meters diameter to match 2.4×4.5m ball mill. 3. The qualified materials from the spiral classifier go to a material mixing tank, there are 5 chemical mixing tanks and 5 chemical storage tanks next to it.
According to the height of overflow dam (the relative position of spiral in tank and slurry surface), spiral classifier can be divided into high dam spiral classifier, low dam spiral classifier and submerged spiral classifier.
In some areas, fluorite rich veins may be weathered to depths of as much as 75 m. Such weathered ore, a mixture of clay and fragments of fluorite and detached wall rock, may be mined open pit with draglines, scrapers, or power shovels to depths of as much as 50 m.
In addition, spiral classifier in the production process of sand and gravel plant, building materials plant, is also commonly used in sand and gravel, slurry cleaning and grading. 04 Suggestions for equipment selection
In mineral processing, the spiral classifier is widely used in the ore dressing plant to divert the ore, or to be used in the gravity ore dressing plant to classify the ore and fine mud, the slurry in the metal beneficiation process, and to remove …
And the coarse particles sinks to the bottom of tank, then it is conveyed by spiral to the discharge port. Usually the spiral classifier and the mill form a closed circuit, and the coarse sand is returned to the mill for regrind. (2) Merits. Simple structure and convenient operation. Small impact of the feeding capacity fluctuation.
The function of the ball mill and spiral classifier is to grind the materials into fine powder to release as much Fe3O4 as possible from the hematite ore to obtain a 100-mesh to 200-mesh slurry. 3. Gravity separation system. The slurry is first sent into the tank, and then pumped into the spiral chute to concentrate the
It increases an automatic sand-return device at the sand-return part. Lift ore sand that discharged at tank bottom to a proper position at tank wall, to adapt the configuration of ball mill cancelled big spoon head.
Our Spiral Classifier is available with spiral diameters up to 120″. These classifiers are built in three models with , 125% and 150% spiral submergence with straight side tanks or modified flared or full flared tanks.
This spiral classifier is widely used to separate mineral sand with closed circuit ball mill. This product can be used for grading sand and fine mud in the gravity separation, classifying mineral size in metal ore beneficiation, mud removal and dehydration in ore beneficiation.
