Abstract. The performance of a circulating air classifier has been studied systematically by conducting experiments over a range of process and design variables. It is found that while the overall induced flow rate is proportional to the speed of rotation of the wheel, the circulation pattern inside the classifier depends on the configuration ...Web

Bi-spiral steel classifiers [8], [9] are one of strategic components of the OCP plants. Altogether in three OCP production regions 29 pieces of such equipment are in operation. Their task is to separate grains in terms of size and weight in a water environment due to the gravity force action [10], [11].Classification products comprise: overflow …Web

In simulation the classifiers were used to detect different fracture types such as Oblique, Displaced, Spiral, Greenstick, Comminuted, Traverse and Linear. • Hand bone X-ray image The input image is hand bone x-ray image and after execution the bone fracture type detected is spiral. The results are presented in figure 2 to figure 11.Web

Spiral operation and partition curves of the particles. A spiral classifier is shown in Fig. 1. The spiral feed that consists of a water-slurry of ground ore enters the top of the spiral. As the slurry enters the spiral various forces (Burt, 1984) act on the particles to operate the separation between light, heavy, coarse and fine particles.Web

Thus, classifiers with a 300 mm spiral diameter revolve at about 8–20 rpm, while the 2000 mm diameter spirals rotate at about 2–5 rpm to give a sand conveying speed of 2–3.5 m/s. The raking capacity of the large classifiers is approximately 200 t/h, while smaller classifiers have raking capacities as low as 1.5 t/h.Web

the water. The classifier has two outputs: the "underflow", formed by sedimented coarse solids; and the "overflow", in the form of an ore slurry with fine suspended solids particles. For proper performance of a spiral classifier, the density of its overflow needs to be controlled by a feeding of dilution water at the input of the ...Web

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.Web
