Primary Crushing. The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph

The main component of the spiral classifier is the spiral. According to its position in the tank and the level of the slurry surface, it can be divided into three types: low dam, high dam, and submerged spiral classifiers. The low dam spiral classifier is rarely used now; the high dam and submerged spiral classifiers are mainly used. 1.

9 Primary and secondary clarifiers essentially share the same primary function: to remove 10 solids from water using sedimentation. They also have similar configurations and designs. 11 However, based on the design parameters listed above, we can examine some fundamental 12 differences between primary and secondary clarifiers.

Operating the spiral classifier at a feed rate, spiral speed and washing time of 6 t, 25 rev/min, and 30 min, respectively, yielded Mn grade of 53%. A Confirmatory test …

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 Processing of Copper Ore Beneficiation. The classification equipment of copper ore beneficiation plant mainly has two types: spiral classifier and hydrocyclone: spiral classifier is mainly used for closed-circuit operation with grinding equipment, or used for washing, dewatering, desliming, etc., for coarse particles The classification effect is better.

Processes at the spiral classifier was adjusted to give final product grades ranging between 50 – 52% Mn after commissioning but recently the grade has reduced to 48 – 49% Mn. This study focused on feed tonnage into the classifier, the speed of the classifier spirals and washing time since the plant was already in operation.

10 000 mtph, depending on crusher design, characteristics of the material to be crushed and desired product. ADVANCEMENTS IN PRIMARY GYRATORY CRUSHING: 1881 – 2003 The primary crushing of rocks does not appear compatible with high tech engineering of the 21st Century. However, it has come a long way from the beginning of the 1800s …

The design of closed spiral classifier (CSC) is inspired by the open spiral separators and hydrocyclones [19], [20]. Feed slurry is passed through a closed rectangular spiral channel at sufficiently high velocity. ... The difference in the densities of the two solid systems helped to characterize the classifier better. To establish the primary ...

Linear Classifiers. Sergios Theodoridis, Konstantinos Koutroumbas, in Pattern Recognition (Fourth Edition), 2009. 3.1 Introduction. Our major concern in Chapter 2 was to design classifiers based on probability density or probability functions. In some cases, we saw that the resulting classifiers were equivalent to a set of linear discriminant functions.

Air Classifiers come into consideration for applications that need ultra-fine particle sizes. meister air classifiers distinguish themselves by their excellent classification characteristics. Utilized as stand-alone machines or in combination with a mill, as a milling and classifying system, the 7 ...
