How to realize the sieving of sand and gravel impurities in bentonite grinding mill

How to realize the screening of sand and gravel impurities in bentonite mill? You may be like me, that industrial grinding equipment is mainly used for powder processing, the removal of impurities on the sand and gravel should choose a vibrating screen and other screening devices are more appropriate, how it is possible to realize the sieving of sand and gravel. In fact, in the bentonite grinding process is sand and gravel decontamination can be achieved, but in the original mill mechanism to make changes, and here also to remind you to consult the grinding plant manufacturers to modify carefully.

Bentonite is a non-metallic mineral with montmorillonite as the main mineral composition, due to the presence of many cations in the layered structure, and unstable, with good ion exchange, so the application is very broad, the current production areas have accounted for 24 areas of industrial and agricultural production more than 100 departments, processing products have more than 300 kinds of products, and therefore often referred to as the "all-purpose soil ". But the quality of bentonite directly affect the quality of the product, bentonite sand content, in the grinding production must pay attention to sand and gravel in addition to impurities, impurities including potassium feldspar, calcium feldspar, silica sand and other montmorillonite other than all the substances, due to the specific gravity of sand and gravel is larger, in the bentonite mill processing process by the rotation of the wind in the gravitational sedimentation to achieve the sieving process. Specific sand discharge method can refer to the following two points:

1. can change the base structure of the bentonite Raymond mill, open small openings at the edge of its bottom, when the equipment is running, the material in high-speed operation due to gravity will form sand separation, than the major gravel at the bottom of the material in the top, the finished material after grinding is taken away with the wind by the analyzer, while the gravel in the centrifugal force is thrown to the edge, with the edge of the natural fall of the lower openings, discharged outside the grinding chamber At this point, the sand and stone separation will be a big success, but there is a point is to pay attention to the handling of impurities discharged sand, can be connected to a belt conveyor at the lower end of the opening of the mill host, discharged sand and stone transported to the correct location for storage and use.

2. In the bentonite mill structure can also be used in another way to improve the realization of the sand function, in the base of the edge of the welded diameter of about 10CM pipe, the port connected to a small cyclone collector, the collector of the upper mouth with a hose connected to the equipment of the blower inlet, the lower mouth for sand discharge. Grinding equipment under normal operating conditions, the mill discharged coarse sand and gravel (sand and gravel mixed with a small portion of bentonite) into a small collector, than the large sand and gravel will fall out of the lower port, the specific gravity of the light fine bentonite will be sucked away from the upper port to be recycled, and the first method of discharging the sand compared to the biggest advantage is that it is the efficient use of resources to achieve a small amount of sand and gravel impurities in the recycling of bentonite materials.

OCP mill applicable material is far more than a bentonite, the use of performance changes need to be based on different materials, to achieve the bentonite sand and gravel impurities screening is not difficult, the nature of the material is different in the grinding will need to make appropriate adjustments to the grinding equipment, such as coal mill, limestone mill, we will be customized for the user's material conditions for you to select the type.
