The spiral classifier can be divided into three types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier. The high dam type spiral classifier means that the overflow dam is higher than the spiral axis of the spiral, but lower than the upper edge of the spiral at the overflow end.

Spiral Classifiers. The shape of the spiral classifier tanks is usually rectangular (Figure 13.1). The feed is introduced at a position about halfway along the length of the settling tank. The tank slopes range from 14° to 18°. The slope is adjusted such that the top end is higher than the height of the overflow weir. The spirals impede the ...

Dewatering. Spiral classifiers are designed to settle and dewater relatively coarse particles from high volume, low percent solid volume streams. Flexibility in layout and mounting positions as well as high resistance in harsh, dusty and ambient conditions are key features that our products can deliver.

The outcome of the studies is the new established operational conditions which is adhered to by the plant, producing a manganese concentrate grade ranging between 52-54%. Keywords: Design of Experiment (DOE), Spiral Classifier, Grade, Manganese Size classification equipment are designed to split a feed of product material into coarse and …

Description: Spiral classifier is one of the most common beneficiation equipment. The application of spiral classifier is very wide. It can separate the different grades products. It can separate the lighter metal mineral particles from the heavier particles. It can separate out the fine particles and liquid from the coarse particles, and can ...

Abstract. Design features of the commonly used classifiers such as the spiral, rake, cone, bowl are described. Descriptions and design of centrifugal classifiers, such as the hydrocyclone, are given in some details. The mathematical aspects of designs that are related to operation of these classifiers and the theory behind the design and ...

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. The single, double or …

Spiral Classifier. A Spiral Classifier is a machine that is primarily used to classify the slimes (fines) from a coarser, sandy sized material. It has an inclined trough with one or two spirals revolving slowly and free from touching the sides or bottom of the tank. The motion of the spiral creates Pool Hindered Settling in the bottom pool area ...

2. 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.
