Description
Technical Field
The utility model relates to a mineral magnetic separation field especially relates to a magnetism, strong magnetism magnetic separator ore discharging device in wet-type cylinder.
Background
The wet type cylinder magnetic separator is divided into weak magnetic separators according to the magnetic field intensity, and the working magnetic induction intensity of the weak magnetic separators is below 250 mT; the working magnetic induction intensity of the medium magnetic separator is between 250mT and 600 mT; the working magnetic induction intensity of the strong magnetic separator is over 600 mT.
The working magnetic induction intensity is different, the corresponding application fields are also different, wherein the weak magnetic separator is mainly applied to the magnetic separation of strong magnetic minerals such as magnetite, and the ore unloading mode is mainly that an induction roller is matched with washing water. The principle is that the induction roller is magnetized in a magnetic field to generate an induction magnetic field, the induction roller is provided with a protruded tip part, the magnetic induction intensity at the tip part is obviously enhanced, in the competition of the magnetic field formed by the magnetic system of the magnetic separator for magnetic mineral particles, the magnetic field force of the mineral particles is stronger due to higher gradient of the magnetic field, the magnetic mineral particles can be adsorbed, then the magnetic field is far away from the magnetic system magnetic field area under the driving action of a motor, the induction magnetic field is rapidly reduced after the magnetic field area is separated, and the magnetic particles adsorbed on the magnetic field are desorbed under the dual action of gravity and washing water, so that the ore unloading of the magnetic mineral particles is realized. The induction roller is distributed around the protruding tip, and the continuous operation of magnetic ore discharging is realized by repeating the action repeatedly under the drive of the motor.
The medium-magnetism and strong-magnetism magnetic separator is mainly applied to the separation of weakly magnetic ores, such as artificial hematite, ilmenite and garnet. The medium-magnetism and strong-magnetism magnetic separators mainly adopt water flushing forced unloading, and three reasons for unloading by using induction rollers are as follows: firstly, because the decay speed of the surface magnetic field intensity of the cylinder of the medium-magnetism and strong-magnetism magnetic separators in the radial direction is higher, the magnetic induction intensity of the tips of the induction rollers at different positions in the magnetic field is larger, the magnetic induction intensity of the tips is higher as the induction rollers are closer to the surface of the magnetic cylinder, if the induction rollers are required to effectively adsorb magnetic particles, the distance between the tips of the induction rollers and the cylinder surface cannot exceed 1.5mm, and the requirements on the processing precision and the installation precision of the cylinder of the magnetic separators are higher, so that the ore unloading efficiency of the induction rollers adopted in the medium-magnetism and strong-magnetism magnetic separators is not high; secondly, because the surface magnetic field intensity of the cylinder of the medium-magnetic and strong-magnetic separator is high, the adsorption force to the induction roller is large, the running resistance is greatly increased, and the induction roller is easy to stick to the cylinder surface in the running process so as to cause danger; and the coarse magnetic ore particles (more than 2 mm) are easy to scrape the induction roller and the cylinder surface and damage equipment.
In conclusion, the medium-magnetic and strong-magnetic drum type magnetic separator is not suitable for an induction roller discharging mode. In addition, minerals are usually required to be deironized in advance by a weak magnetic separator before entering, magnetite or mechanical iron mixed in ore pulp is removed in advance, but strong magnetic substances are often mixed by about 2% in actual production, the strong magnetic substances can cause difficulty in ore unloading in subsequent medium-magnetism and strong-magnetism operations and rub with a cylinder surface along with the rotation of the cylinder surface, the service life of the cylinder is shortened, the discharge hole of the magnetic separator can be blocked, the yield of the magnetic substances is reduced, water spraying or a scraper blade is difficult to remove the magnetic substances in time, and a manual unloading mode is usually adopted in actual production.
