Hammer Crusher. Ceramic Ball Mill. Briquette Machine. Raymond Mill ...
cost and less space required have caused operation with spiral classifiers to becomerestricted. The application range ofspiral classifiers range is 0.070 to 1 mm, depending on the material to be separated. Compared to cyclones, spiral classifiers cover a coarser separation range. Autogenous cyclones also cover a coarser range, replacing
Ghana Manganese Company (GMC) has renovated their oxide washing plant by integrating it with a spiral classifier to make a batch system operating process. Particle size of <3.35mm (Mn grade of 43-47%) obtained from the primary section of the plant served as feed to the classifier and with the plant condition (i.e. at 60 min washing time, 30 ...
Introduction. Spiral Classifier also can be called spiral separator, screw classifier or screw separator. It is widely used in the concentrator and make up a closed-loop with ball mill. We produce high weir type classifier, single and double spiral type classifier and immersed single and double spiral classifiers. Our spiral classifiers are ...
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.

Hammer Crusher. Jaw ...
This spiral classifier/dewatering screw is a multi-purpose machine. As a classifier, it separates out the smaller waste particles from the ore processor tailings. The larger …
2. Floor area. Obviously, the footprint of the hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the area of the hydrocyclone is only 1/30~1/50 of the spiral classifier. The equipment footprint requirements also limit the application of spiral classifiers to a certain extent. 3.
Spiral Classifier. Capacity: 21-1785 t/24h (over flow); 145-23300t/24h (returned sand); Up to 150% spiral submergence. Spiral diameter: 500-3000mm; Single, …
Spiral classifiers are often combined with ball mills to form a closed-circuit cycle to separate ore sands, or to classify ore sands and fine mud in mineral processing plants. It is also used for or washing clay sand, silica sand, tailings dehydration, tailings water separation, etc. It is one of the main equipment for mineral processing.
Providing you reliable Spiral Classifiers, Vibrating Screens, Screening Plants, Vibro Feeders, Log Washers, Scrubbers. About Us Durga Metal Profiles is a progressive organization engaged in the manufacture of mineral processing machinery.
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.
The overflow weir of high weir classifier is higher than the center of the spiral axis at lower end, but lower than the upper edge of the spiral blade. The length of liquid level is short, so its surface can directly get the stirring effect by the spiral blade, therefore it suitable for coarse particle classification, usually the classified ...
Introduction of Spiral Classifier. Spiral Classifiers is art of separating the solid particles in a mixture of solids and liquid into fractions according to particle size or density by methods other than screening. In general, the products resulting, a partially drained fraction containing the coarse material, called the underflow; and a fine ...
