Die rock permanent magnet magnetic roller

Magnetic rollers, also known as magnetic pulleys, are available in two types: permanent magnets and electromagnetic ones. The diameter of the rollers with more specifications ranges from to to, and the corresponding belt conveyor width ranges from to.
.> Mainly suitable for the following purposes:
.> Rough selection of lean iron ore after coarse or medium crushing to remove surrounding rocks and other waste rocks to improve the grade and reduce the load of the next process.
.>, used in the hematite reduction closed-circuit roasting operation to sort out the raw ore that has not been fully reduced and return it to be burned again.
.>, used in the ceramic industry to remove iron mixed in porcelain clay to improve the quality of ceramic products.
.>, coal-fired mines, foundry sand, refractory materials and other industries that require iron removal operations.
.>Separation Principle
.>Series permanent magnet magnetic rollers are often used in pre-selection operations before the ore enters fine crushing or grinding to remove gangue, surrounding rock and other waste rocks mixed in the ore. The sorting principle of permanent magnet magnetic drum is shown in the figure. The magnetic drum is usually used as the driving drum of the conveyor belt. When the materials pass through the magnetic drum on the conveyor belt, they are sorted. When the magnetic materials move to the top of the drum, they are attracted and automatically fall off when they turn to the bottom. The non-magnetic materials fall directly along the horizontal parabolic trajectory. Magnetic materials and non-magnetic materials will enter different receiving hoppers respectively. According to the different wrapping angles of the magnetic system of permanent magnet magnetic rollers, they can be divided into permanent magnet pulleys and permanent magnet rollers. The magnetic wrap angle of the magnetic pulley is that the magnetic pole groups are evenly distributed around the inner circumference of the cylinder to form a full-circle magnetic system. The magnetic system and the cylinder rotate at the same speed as the belt, and the operation is stable, safe and reliable. Since its unloading principle is realized through the drag force of the belt, it is generally used for permanent magnet magnetic drums with magnetic field strengths below to reduce damage to the belt. The cross-sectional view of the magnetic system of the magnetic pulley is shown in the figure.
.>Technical Features
.>High-performance composite magnetic system. The magnetic system uses new high-performance magnetic materials, gold iron boron magnets and high-quality silver ferrite materials. Due to the improvement of the magnetic system structure, the overall magnetic field is improved. The distribution curve increases the depth of magnetic field action and the upper limit of the sortable particle size is.
.>The high-strength and high-reliability mechanical structure ensures the normal operation of the magnetic drum in various harsh environments.
.>The magnetic declination angle adjustment device is flexible and reliable, so that the circumferential position of the magnetic system in the drum can be adjusted arbitrarily, even when running at different belt speeds, so that large ores can be placed in the maximum magnetic zone, which is beneficial to sorting. .
.>Strong adaptability and wide range of applications. The permanent magnet magnetic drum has now realized dry pre-selection of iron ore. In addition, it is also widely used in many fields such as waste rock recycling in ore dressing plants, steel slag treatment in steel plants, raw material removal in cement plants, power plants, coal, ports, and building materials industries. Iron etc.
.>Development direction
.>Optimization of performance parameters of the equipment itself. By optimizing its mechanical structure through advanced optimization software, the structure itself can be made more reasonable, greatly reducing the quality of the equipment, facilitating installation, inspection and maintenance, and flexible process adjustment. In addition, with the continuous advancement of magnetic materials and the continuous efforts of scientific researchers, reasonable magnetic systems are designed for different mineral types and different particle sizes to achieve the optimal sorting effect. The new nickel iron boron magnetic material not only has high magnetic force, large magnetic field action depth, reasonable distribution of magnetic properties, is light in weight and easy to assemble, but also improves the pre-selection process indicators.
.>The enlargement of permanent magnet magnetic rollers. Large-scale mineral processing equipment is an important direction of development at present. Because large-scale equipment not only has stable and excellent separation indicators and large processing capacity, it can simplify the process configuration, but also has simple operation and convenient management. It covers a small area, saves water, saves electricity, and has low production costs. The advantages thus have broad application prospects.
.>Fine-grained dry pre-selection. Because the particle size of conventional permanent magnet magnetic rollers is relatively coarse, it cannot achieve the desired effect for the separation of fine-grained minerals, especially for powdered ores. When conventional magnetic rollers are used to separate powdered ores, fine particles are seriously included. In order to achieve a better sorting effect, it must be used. The thinning of the material layer causes the processing capacity to decrease.
.>Application scope
.>Magnetic separator is widely used in resource recovery in wood industry, mining, kiln industry, chemical, food and other factories. It is suitable for magnetite, pyrrhotite, Wet magnetic separation of roasted ore, ilmenite and other materials is also used for iron removal operations of coal, non-metallic ores, building materials and other materials. It is one of the most widely used and versatile models in the industry. Magnetic separators are widely used in the industry. One of the most widely used and versatile models in the world, the magnetic separator is used to remove iron powder from reused powdery granules. It is widely used in resource recovery wood industry, mining, kiln industry, chemical, food and other factories. The magnetic separator is suitable for wet magnetic separation of magnetite, pyrrhotite, roasted ore, ilmenite and other materials below the particle size. It is also used for iron removal of coal, non-metallic ores, building materials and other materials
. >Characteristics of permanent magnet magnetic rollers:
.>r series of mid-field strong permanent magnet rollers (divided into two magnetic structures: semi-magnetic and full magnetic) are mostly used to purify powdery, granular and small block materials. The processing or recycling of iron provides reliable protection against damage and wear in crushers, grinders and presses. It is easy to install, has strong suction power, has no energy consumption, works continuously and is simple to operate. Designed according to the belt conveyor standard, it can meet the requirements of users for high field strength and large depth iron removal. Widely used in metallurgy, ceramics, abrasives, emery sand, non-metallic ores, refractory materials, mining, food, chemicals, glass, building materials and other industries.
