The magnetic separation process is achieved by the effect of magnetic force and mechanical force on ore particles in the magnetic field of magnetic separator. The particles with different magnetic move along different tracks, and thus two or several individual mineral processing products are separated. According to the dry and wet degree of minerals, the types of magnetic separator can be divided into dry magnetic separator and wet magnetic separator . So, how should we choose the right type of magnetic separator? 1. Application of types of magnetic separator Wet magnetic separator is suitable for the coarse separation of lean iron ore after coarse or medium crushing, raw ore separation that has not been fully restored in the closed-circuit roasting operation of hematite reduction, iron removal from petuntse in the ceramic industry, as well as other iron removals in foundry sand, refractory materials and other industries. Besides, wet magnetic separator is suitable for those areas...

Ball mill is the key equipment for material grinding in mine, cement, thermal power and other industries, how to choose the types of ball mill is very important. Selecting the types of ball mill is mainly up to the production capacity, namely processing capacity. There are many factors that are related to the processing capacity of ball mill, such mineral grindability, particle size of feeding and final product, type and size of grinding machine, shape of the lining board and size matching, shape, size and shape of grinding medium, matching proportion and its physical and mechanical properties, mill speed, medium charge ratio, slurry concentration, as well as the type of classifier and working system. As there are a lot of factors affecting the processing capacity of the ball mill, so the processing capacity of the ball mill is generally determined by an accurate experiment in the mine design. Here are some suggestions from Xinhai for selecting the types of ball mill: 1.Rod Mill It...

It is the common goal for each mining machinery manufacturer to improve the production capacity of the equipment. As to improve the production capacity of ball mill , Xinhai has its own tips. In fact, every ball mill manufacturer will put much attention to the structure of the ball mill when designing, and try best to improve the production capacity of ball mill. After all, the production capacity means competitiveness. There are many methods to improve the production capacity of ball mill, and different methods have different effects. Improve the production capacity of ball mill is also to improve the work efficiency of the grinding system. Through the long-term observation, Xinhai found that there were a few main factors that influenced the working efficiency grinding system, like circulating ventilation, air pressure, quantity of grinding medium, liner material and shape. Except for these external factors, there are some are internal factors that may have the negative effect on b...

Xinhai wet magnetic separator is mainly used for wet magnetic separation process, and it is suitable for dealing with magnetite, pyrite, calcined ore, ilmenite and other materials whose (particle size is less than 3mm). besides, it is also used in the iron removal of coal, non-metals and building materials. The magnetic system of the magnetic separator is made of high-quality ferrite material and thulium magnet. The average magnetic flux density of the drum is about 100 ~ 600mT. Here is mainly about tailings discarding by magnetic separator. This wet magnetic separator adopted a kind of newly developed Nd-Fe-B magnetic material with high permeability and magnetic energy as the magnetic source. In addition, the magnetic separator design was based on the magnetic induction of ores and actual operation analysis. so, it is widely used in the iron removal of various kinds of mines, such as manganese ore, limonite, hematite, goethite, siderite, cerium chromite, niobium, tantalum, titanium...

Raymond mill is a common grinding equipment , which is familiar to many people. After a period of time, there are always a lot of problems. Today, Xinhai will explain several reasons that cause overtemperature of Raymond mill, then give you the corresponding solutions. Overtemperature of Raymond mill includes different phenomena, like fan motor heating, overtemperature of bearing. Facing these situations, the user should firstly find out the reasons for the overtemperature, and then take the appropriate methods. 1. Check the extension pipe, oil viscosity and oil brand. 2. The feed bear of roller device shall be oiled in time, and cleaned regularly. Besides, the oil seal shall be changed according to regulation. 3. The grinding ring shall be oiled at regular intervals. 4. The indoor temperature of bear shall be less than 70℃. If the temperature is too high, the bear and various spare parts shall be cleaned at least one time. 5. Maybe the fan motor heating is caused by too high wind p...
