Research on unit consumption and service life of ball mill liner

By -

 The liner is a key easily damaged part for the ball mill. The unit consumption and service life of the liner are inseparable from the working efficiency of the ball mill.

     The factors that affect the wear rate of the liner mainly include the corresponding particle size and hardness of the material to be ground, how much electricity is needed to grind each ton of material, the diameter of the mill and its speed, the structure of the liner and the wear resistance of the liner material The percentage of the weight and volume of the original lining board and the original lining board. For the current process, the metal liner is mostly low-grade ore first-stage grinding, but for most low-grade ore, the content of silica and other hard grinding and corrosive minerals are very high, but in this case In the second-stage grinding process, many concentrators will choose ball mills to use rubber liners.

     The service life of the cylinder liner is four factors: macroscopically speaking, the resistance to impact failure damage; macroscopically speaking, the resistance to fatigue failure damage; the resistance to surface cutting or cutting wear; the surface microscopic resistance to impact fatigue and wear Kind of operating conditions.

【Phosphate ore flotation】Phosphate ore beneficiation and flotation reagents

By -

Phosphorus is an important raw material for the production of phosphate fertilizer, yellow phosphorus, phosphoric acid, phosphide and other phosphate products, and is a non-renewable and alternative resource. The reserves of phosphate rock resources in my country are relatively large, but more than 70% of them are low-grade and lean ore, which cannot be industrialized only by the scrubbing process. At present, medium and low-grade phosphate rock resources are mainly used for enrichment, and the flotation effect of phosphate rock depends on the interaction between mineral particles and air bubbles in the water medium, among which flotation reagents are particularly important. Commonly used flotation processes for phosphate ore beneficiation are: positive flotation, reverse flotation, first positive then reverse flotation, first reverse then positive flotation and double reverse flotation. 1. Positive flotation process of phosphate rock The process is to grind the phosphate rock until th

Selection of spodumene flotation reagents

At present, the  beneficiation methods of spodumene  mainly include: manual separation, thermal disintegration, magnetic separation, resuspension method,  flotation method  and combined beneficiation method. Among them, the flotation method of spodumene is the most studied in the laboratory and the most widely used mineral processing method in industry. 1. Cationic collectors The cationic collectors used in the flotation of spodumene ore are mainly amine collectors, which flotate gangue minerals such as quartz, feldspar and mica under acidic conditions, and leave the spodumene at the bottom of the tank. This method is often used in the roughing of spodumene, and cannot directly obtain spodumene concentrate with higher purity, and needs to be used in conjunction with other sorting methods. In production practice, Yan Gengsheng used  the process of flotation of spodumene  with mixed soap and diesel oil under alkaline conditions after flotation of mica with phylloylamine under acidic cond

How to use inclined plate thickener for tailings dry discharge

By -

 Tailings treatment is an important part of mine production. Concentration in dry tailings discharge is an important link in achieving dry stacking. It not only directly affects the processing capacity of filter equipment, but also affects the resistance of filter cakes. The particle is resistive to the filter cake, so according to the characteristics of iron tailings, there is a new type of thickener . The flow of tailings slurry in the thickener is ideally slow. As soon as the solid particles leave the flow layer, they will be considered as sediment. This model is also called shallow sedimentation. The sedimentation occurs in the void between the inclined plates. Within the cavity, but due to the small spacing between the inclined plates, it creates favorable conditions for the formation of laminar flow. The clarified overflow water moves upward along the inclined plate space, and the solid particles settle between the two plates, and only need to settle to a small distance to fall o
