classifier spiral pulp

The shape of the spiral classifier is a rectangular chute with an inclination angle of 12°- 18.5°. The bottom is semicircular, and one or two longitudinal shafts are installed in the groove. The spiral blades are continuously arranged along the shaft length, and the spiral shaft is driven to rotate by the upper end transmission mechanism.

Now, the common classifiers in mineral processing plant are mainly mechanical classifier and hydrocyclone. Among them,mechanical classifier can be divided into spiral classifier, rake classifier,tank classifier and other types.

High spiral classifier operation: the grinded pulp is fed into tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low speed rotation stirs the slurry, so that the fine particles rise, and the coarse particles sinks to the bottom of tank.

Table of Contents The size of mechanical classifier required for a particular job depends on the following factors: Tons of dry solids to be overflowed per 24 hours. This is simply a predetermined tonnage. Mesh size at which separation is to be made. The mesh size is determined by laboratory tests or is already known […]

Change the traditional discharge mode at the front end of the spiral classifier and adopt bilateral discharge, which can shorten the movement path of ore particles in the classifier, avoid pulp backflow, discharge fine particle overflow in time and shorten the settling time. Add mixing device at the lower end of the classifier.

Spiral Classifier for Mineral Processing. In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn't lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do.

Spiral classifier working principle: Fine ore pulps are fed into water tank through feeding opening located in the center of settling zone. Beneath the inclined water tank is the ore pulp classification zone where ore pulps are stirred by low-speeded impellers. Fine ore particles are lifted up and then spilled out the overflow opening; coarse ...

Spiral Classifier. In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence … See more

Classifier Slope. In general the classifier should be installed with a slope of from 3″ to 4″ in 1 ft. The steeper the slope the less the pool area of a given size classifier. The less the pool area the less the capacity. The maximum capacity for any mesh separation is obtained at a slope of about 3″ in 1 ft.

As the spiral rotates in low speed to stir the pulp and makes the light and fine particles suspend on the top and overflow to the edge to next processing step. On the other hand, the heavy and rough particles settle …

Spiral classifier (Fig. 1), a mechanical classifier, is one common equipment used for classification in most processing industries. This equipment has one or more spirals revolving slowly and freely on ... classification is to agitate the pulp and transport the Therefore, with increased spiral speed during washing, the materials do not get ...

The spiral classifier is one of the common and key equipment in flotation separating process. We should know about its structure and working principles well before use it. 1. After the turning of helicoids, begin to fill the ore pulp and …

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 types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier

The spiral classifier is one of the common and key equipment in flotation separating process. We should know about its structure and working principles well before use it. 1. …

small spiral classifier to study the effects of design variables (weir height and slope) and operating variables (feed flow rate, pulp density, and size distribution) on the performance of the classifier. The analysis of the experimental data has led to the development of a mathematical model of a spiral classifier ...

Concentrate grade improved as the feed pulp densities increased. The Spiral concentrator has performed better at feed pulp density of 30% by producing concentrate of high grade (93.5%) and with highest recoveries of 96%. The desliming of raw sand has been done using using hydrocyclone. When the deslimed feed is fed to the spiral, high

We located in the Donggang City. It covers a total area of 200,000 square meters, including 150,000 square meters of standardized workshops. There are more than 200 sets of various large and medium-sized metal processing lathes, riveting machines, welding equipment, and assembly equipment.

The spirals impede the downward slurry movement resulting in some build-up. The sides are therefore raised. Classifiers with raised sides are generally …

The spiral classifier mainly rotates at a low speed by the spiral to stir the pulp to make the fine particles suspend to the top, flow to the overflow weir and overflow, and the coarse particles sink to the bottom of the tank, and are conveyed by the screw to the discharge port as returned sand. . The hydrocyclone needs to be discharged on the ...
