Description

TECHNICAL FIELD

[0001] The utility model relates to a magnetic separator equipment technical field, concretely relates to a quartz stone raw material electromagnetic adsorption impurity removal device. BACKGROUND

[0002] In order to improve the grade of quartz sand, reduce the iron impurity content, quartz sand production and processing enterprises usually adopt the magnetic separation method to remove the iron impurities in quartz sand. The main mineral in quartz sand, quartz, is a diamagnetic substance and cannot be magnetized in a magnetic field. The impurity minerals containing iron in quartz sand, such as hematite, limonite, magnetite and goethite, are mostly magnetic substances and can be magnetized in a magnetic field. The magnetic separation process utilizes the magnetic difference between quartz and impurity minerals, and separates the magnetic impurities from quartz sand through the action of a magnetic field.

[0003] At present, the quartz stone raw material magnetic separation of impurities basically uses a magnetic separator. The drive roller of the conveying belt is set as a magnetic roller, so that the magnetic substances on the conveying belt are adsorbed by the magnetic roller. After reaching the end of the conveying belt, the quartz sand falls off the conveying belt due to gravity, and the adsorbed magnetic substances gradually fall to the ground due to gravity after leaving the magnetic attraction range at the bottom of the conveying belt. However, during the falling process of the magnetic substances, if the magnetic substances are in the form of small particles, the magnetic substances will scatter in the air, resulting in that the impurities after magnetic separation cannot be collected well.
