In addition, what should be paid attention to is the centrifugal filter, which is an efficient dewatering equipment , which is focused on research at home and abroad.
How to choose a beneficiation filter and its auxiliary equipment
Most metal ore dressing plant filter is commonly used vacuum filter, it is divided into an outer cylindrical filter type filter, the filter type cylindrical filter and a filter disc three kinds, in addition to the magnetic filter Machine, folding belt filter and filter press. The choice of filter should be determined mainly according to the nature of the material to be filtered (such as particle size characteristics, density, etc.), the amount of concentrate, the nature of the slurry and the requirements for product moisture. The internal filter is mainly used to filter concentrates containing both coarse and fine particles, especially for coarse aggregates with faster sedimentation rate. When filtering, coarse particles can be preferentially accumulated in the lowermost layer of the filter cake. The surface of the filter cloth is formed into a coarse "bed", which reduces the clogging of the stable cloth and increases the speed of the filtrate, thereby improving the productivity of the filter. Since the magnetic iron ore concentrate "magnetic reunion" phenomenon is more prevalent, the filter type filter for filtering iron ore concentrate to obtain the more common applications, magnetic vacuum filter for processing the magnetite concentrate, higher filtration efficiency The filter cake has a low moisture content. When filtering concentrates that are not pre-concentrated, an internal filter vacuum filter is also used, but must be considered for backup. The disadvantage of the internal filter is that the operation is inconvenient, and the replacement of the filter cloth is also troublesome. The external filter vacuum filter is more suitable for processing fine-grain concentrates, and it is suitable for application when the product moisture content is low. The disc filter is also suitable for filtering fine-grained materials and materials containing more shale, but the moisture content of the filter cake is slightly higher than that of the external filter. The folding belt filter and the filter press are more efficient for fine-grain concentrates with more muddy and more viscous concentrates than other types of filters, and the concentrate products have lower moisture.
