These auxiliary brush machines are designed for automatically trimming and flagging the brooms and brushes with flat or curved profiles. Different brushes may need different models of trimming and flagging machines. And dust suction unit is included to remove dust and waste material and keep the machine clean. Working together with the brush making machines, these trimming and flagging machines can reduce the production processes and give an extraordinary high output of finished products.

YGl-15 permanent magnet vertical ring high gradient magnetic separator
YGl-15 permanent vertical ring high gradient magnetic separator is HD technology development, production of a new intensity magnetic separation device adapted to wet grain size selected from 1 ~ 0mm weakly magnetic minerals (iron oxide ore, hematite, siderite iron ore, manganese carbonate ore, etc.), can also be used for non-metallic mineral (quartz, feldspar powder) was purified iron.
Working principle: The magnetic box of the magnetic separator is equipped with a magnetic stainless steel rod (the thickness of the magnetic stainless steel rod can be selected according to the ore particle size, sorting operation and the requirements of the sorting index). During normal production operation, the vertical ring rotates in the calibration direction. The slurry is fed to the ore mining area at the lower part of the vertical ring through the feeding tank and flows vertically downward through the magnetic medium. At this time, the magnetic medium box is in the magnetic field area, and the medium is magnetized. The magnetic medium surface forms a high gradient magnetic field, which generates a strong magnetic force. The magnetic ore particles in the slurry are adsorbed on the surface of the magnetic medium, and are brought to the top non-magnetic field area with the rotation of the vertical ring, and are reversely rushed into the fine by the concentrate washing water. The mineral tank; the gangue and the magnetic particles with extremely weak magnetic properties are not affected by the magnetic force, and flow down through the medium into the tailings trough and exit the machine, thereby completing the whole process of sorting.
The machine is equipped with a pulsation device. During normal production operation, the magnetic medium in the lower part of the vertical ring is immersed in the slurry. The tympanic membrane of the pulsating device is driven by the pulsation box to reciprocate, and the slurry in the tailings tank is reciprocated up and down. . The pulsating slurry fluid keeps the ore particles loose during the sorting process. This can greatly reduce the mechanical inclusion of non-magnetic ore particles, thereby significantly improving the grade of the magnetic concentrate, and the slurry pulsation is also very advantageous for preventing the blockage of the magnetic medium.
Equipment structure: As shown in the figure below, the magnetic separator is mainly composed of a pulsating mechanism, a rotating ring driving device, a feeding tank, a rotating ring, a frame, a magnetic system and the like.
The magnetic separator is based permanent magnetic system, the current domestic production of high-grade rare earth magnet block (titanium-iron-boron) assembled. The background magnetic induction intensity is 0.3~0.6T. The magnetic magnetic medium is a magnetic conductive stainless steel rod. The biggest feature of this machine is energy saving, and the power consumption is only less than 20% of the power consumption of the same specification electromagnetic high gradient magnetic separator.
The vertical ring operation adopts positive ore feeding, reverse flushing concentrate, and is equipped with slurry pulsating mechanism. Therefore, it has a large enrichment ratio, good sorting effect, medium is not easy to block, high operating rate, and mineral amount and concentration in production. It has the advantages of strong adaptability to fluctuations, safe and reliable work, simple operation and convenient maintenance.
