Aug 06, 2015 The spiral classifier such as the Akins classifier consists of a semi-cylindrical trough (a trough that is semicircular in cross-section) inclined to the horizontal. The trough is provided with a slow-rotating spiral conveyor and a liquid overflow at the lower end. The spiral conveyor moves the solids which settle to the bottom upward toward the top of the trough

Spiral Classifier. The Spiral classifier is widely used in ore dressing plant and ball mill to form closed-circuit circulation and separate ore sand, or in gravity ore dressing plant to classify ore sand and fine mud, in metal ore dressing process to carry out particle size classification of ore pulp, and in ore washing operation to desliming, dehydration and other operations
Spiral Classifier. Spiral Classifier is a traditional type of classification equipment, mainly for metal mineral processing for the slurry density and particle size on the wet grade, mining operations could also be used in the flow desliming. Model: Submerged series and High Weir series. Spiral Diameter: 300-3000mm. Sink Length: 3000-14300mm
The spiral classifier mechanically classifies through the mechanism of different sedimentation speed of solid particle in liquid due to different size and different specific gravity: the fine ore grain floats in water for overflowing; and the coarse one sediments onto tank bottom and then is pushed upwards by spiral for discharging
Spiral classifier main technical parameters Note: 1. Calculation of production capacity is based on the proportion of ore 2.7, overflow size 0.15mm (for high squat type) or 0.074mm (for submerged type). 2. Angle of inclination α = 14 ~ 18 30 by the user according to the installation needs to customize
Mineral processing spiral classifiers are used to classify the ore sand and the graininess of ore pulp in metal beneficiation and desliming, dewatering and other processes in ore-washing operations. This classifier can be used with a ball powder mill and it is a great choice for use in beneficiation plants

Spiral classifier is a type of classifying equipment which realizes mechanical classification under the principle that materials settle in the liquid at different speeds due to different grain sizes and weighs: Fine grains float in the water and move out in case of overflow while coarse grains sinks to the bottom of tank which are then pushed
Spiral classifier is also known as mineral processing spiral classifier, which is a kind of mechanical grading equipment. It is developed based on the difference of solid particle sizes, proportion and settling velocity in liquids of ores, so that the floated fine particles will flow away; the coarse particles will sink to the bottom and then discharged after being pushing by the spiral
Sep 29, 2017 It is evident that no linear classifier will be able to do a good job classifying spiral data where the boundary between two classes is a curve. A simple two layer network with RELU activation on the hidden layer automatically learns the decision boundaries and achieves a 99% classification accuracy on such a data set
The basic structure, classification principle and low efficiency of the traditional spiral classifier were analyzed. The trial industrial comparative experiment was carried out by using φ300 4500 spiral classifier with the two-sided overflow and the port side overflow at the same parameter. The experimental results showed that, the qualified fine materials could overflow with the
Sep 23, 2019 The spiral classifier is one of the important mineral processing equipment, whose working principle is to classify the materials by using the difference in the settling speed of solid particles in the liquid. The classifying effect of the spiral classifier will directly affect the content of the qualified product in the returned sand, thus affecting the grinding efficiency of the
The parameters of the linear classifier consist of a weight matrix W and a bias vector b for each class. Lets first initialize these parameters to be random numbers: # initialize parameters randomly W = 0.01 * np. random. randn ... Neural Network classifier crushes the spiral dataset

Technical parameters Product introduction Spiral classifier is widely used in mineral processing and forms one closed circulation with grinding equipment. It is applied for the per-classification, fine-grained mineral mud off, dehydration, washing, grading and so on. It can efficiently control mineral particle size, improve the grinding
Spiral classifiers. A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough (Burt, 1984). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral
