Product Introduction

Product Introduction:

Hydrocyclone is used for separating and removing heavy mud and sand of coarse particles and sometimes for dehydration of slurry. The Hydrocyclone separator has two types of pressure type and gravity type made up of either cylindrical structure or metal pipe. Slurry is fed through the top of the structure (or metal pipe) by means of pressure or gravity along the tangent line. Coarse and thick particulate matters are thrown to the wall, rotated down and discharged together with the concentrated liquid formed under the action of centrifugal force. Small particulate matters are discharged together with secondary upward vortex after rotated to some extent. Hydrocyclone / cyclone filter is mainly used for classification, separation, concentration and desliming in the mineral mining industry. When the hydrocyclone is used as a classifier, it is mainly used to form a grinding and classification system with a mill; when it is used as a deslimer, it can be used for desliming in a gravity concentrator; when it is used as a concentrating and dewatering device, it can be used to concentrate ore dressing tailings and send them to fill underground mining tunnels. The hydrocyclone sand separator has no moving parts, simple structure, large capacity per unit volume, small area, high classification efficiency (up to 80% ~ 90%), fine classification granularity, low cost, and low material consumption.

Material

Three different material types for choices:

1). All casted polyurethane (PU) 2), All casted carbon steel lined with PU.

3), All casted carbon steel lined with ceramic.

Material Features

Eastman adopt the high quality polyurethane, the shore hardness is 75-85. Very high strength, high abrasion resistance and is extremely resistant to oil. good resilience and aging resistance.

Applications:

1.Closed circuit grading, desliming
2.Mineral Classification
3.Concentrate or Tailing Thickening, Dewatering
4.Tailing damming and filling cyclone also can be used for pre-selection or rough selection of ore.

The working principle of the cyclone is mainly centrifugal sedimentation. When the two-phase (or three-phase) mixture to be separated enters the cyclone at a certain pressure from the feeding port of the cyclone, a strong three-dimensional elliptical strong rotating shear is generated. Cut turbulent motion. Due to the different density of the particles, the centrifugal force, centripetal buoyancy, and fluid drag force are different. Due to centrifugal sedimentation, most of the coarse particles (or heavy phases) are discharged through the swirler bottom outlet, and most of the fine particles ( Or light phase) discharged from the overflow pipe to achieve separation and classification.

1 The 3-dimension snail-shaped feeding structure makes it possible to feed minerals in circumferential and axial directions. This design can tremendously improve classification efficiency in three ways------first of all, after entering the hydraulic cyclone, minerals avert from being disturbed by turbulent flows occurring near overflow pipes; secondly, the speed of coarse ore cyclone is accelerated towards underflow outlet; thirdly, minerals avoid swift rotating.

2 The square pipe-type feeding model enables ores to get closer to the inner wall of hydraulic cyclone, which contributes to the lightest abrasion of feeding ores and the strongest divergent forces of ores. Consequently, abrasion of feeding box is reduced to the lowest level.

3 The unique adjustment device of wedge-shaped feeding opening can quickly adjust the feeding size, so classification efficiency is hugely raised.

4 The wedge-shaped adjusting valve constitutes a replaceable part for the inlet pipe, so there is no need to change the whole liner of hydraulic cyclone.

5 The premium abrasion performance of liner made from Xinhai abrasion-resistant rubber can considerably reduce using cost, and maintain the inner dimension and shape of hydraulic cyclone, so the stable classification efficiency is achievable.

6 Our company can also provide molding abrasion-resistant rubber liner and cold bonding abrasion-resistant rubber liner, the service life of which is extraordinarily long.

7 The appropriative software helps to choose the right mode accurately and quickly.
