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 type vacuum filter is more suitable for the treatment of fine-grained concentrate, and it is suitable when the product moisture requirement 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 other is the belt filter and the filter press. For fine aggregates with more muddy and higher viscosity, the filtration efficiency is higher than that of other types of filters, and the water content of concentrate products is also lower.
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.
Mud Pump for oil drilling
Mud pump has a longer stroke and can be operated at a lower stroke, thus improved the water supplying perfor-mance effectively and extended the lifetime of expendable parts in the fluid end greatly.
The power end uses combined lubricating system of forced lubrication and splash lubrication. Reliable to lubricate and promote the service life of power end.
This series mud pump are strictly manufactured according to API Spec 7k "the Equipment Specification of Well Drilling and Repairing", and are tested accordingly when leave factory.
Features of drilling rig mud pump
1. The pump has features of advanced structure, small volume, reliable operation, easy maintenance.
2. The cylinder is made of alloy steel forgings, and the three cylinders of each pump are interchangeable.
3. In order to enhance its corrosion resistance, the cylinder surface is processed by chemical nickel plating.
4. The design of straight-through cylinder valve structure, reduced the volume of the hydraulic cylinder and increased the volumetric efficiency.
