Limonite magnetic separator roughing and useful to be necessary conditions, magnetic separator drum absence of exceptional circumstances, generally do not need maintenance, but it should be normal maintenance (small
, Medium, Large and maintenance). We know that magnetic separator equipment in the work of the magnetic drum is prone to wear and tear, severe magnetic roller sleeve worn leather will appear the phenomenon, grinding
After breaking the magnetic roller pulp will enter, which would adsorbed on the surface of the magnetic system, which has led tube between the skin and the magnetic locking system, or slurry into the bearing lead to bearing damage
Bad, to make the whole damage does not work.
Beijing General Research Drawer magnets Institute of Mining and Metallurgy Luo Jiake, Luo Zhongyi other magnetic separator equipment expert since 1976, through a lot of research work, magnetic separator technical experts to develop
Selective (magnetic) flocculation to remove mud new technology, without organic polymer flocculant, can achieve fine-grained iron ore and iron silicate basin separation. The process applies not only to
Sorting SiO2 containing up to 16% of the poor aegirine-type oxide ore, but also for sorting fluorine fluorite up to 13% of the ore dilution test. Separator technical staff to analyze the work
Art is characterized by fine-grained magnetite as a reunion with the medium, sodium hydroxide and sodium silicate (pH = 9.5 - 11.5) in the medium, through several off the mud, you can get high-quality
Iron ore, separation indexes quite satisfactory.
In order to investigate the suspension magnets magnetic selective flocculation method Baotou mine Desliming scope, select the type aegirine, fluorite type and mixed type three kinds of oxide ore poor conduct verification tests.
The results (Table 5-20) shows that although the three ore containing F, SiO2, and ferrous oxide containing relatively large changes, but after adjusting the number of agents and off the mud, can obtain satisfactory
Sorting of targets. Permanent magnetic separator is mainly used for magnetic separation of materials, the use of magnetic difference between the ore in the magnetic separation equipment, mainly for magnetite-election
Mine roughing and selected. Permanent magnet drum magnetic separator magnetic system by a strontium ferrite magnet blocks. Alternating polarity magnetic poles distributed along the circumference.
Oil separator selected iron has good sealing characteristics, in general, the device responsible for the machine bearing the entire load, so good lubrication of the bearing Shou
The length of life has a great impact, it directly affects the life of the equipment and the operation rate of the size, thus requiring the injected oil must be clean, clean, have good lubricating
Good tightness; magnetic separator rotating bearings, roller bearings, all gears, activities bearings, sliding plane and so need to have good lubrication. The oil machinery parts per eye
Classes plus a low-melting calcium-based grease. Bearing oil temperature should be controlled within a certain range, too easily lead to bearing damage. The bottom discharge activity unit
Frame plane can not have dust and other materials, always wipe the body, clear the residual mineral conveyor belt and dust, keep the equipment in good operating environment. Doing so can
Will be able to maximize the use of magnetic separator to maximum effect. Specific maintenance content is: do not disassemble and clean the cylinder body gear (or cycloid planetary gear) and the bearing, running zero
Parts and replace cooling lubricants and solutions.
Specifically: unloading all parts, inspect, repair or replace, any oil-filled electric drum of oil, should be strictly in accordance with the instructions specified in the oil types used
User shall not arbitrarily change the oil seed, to prevent motor burnout. Detach the stand, cover, cylinder, cylinder wall and the drive body cleaning, checking gear, cycloid, bearing wear
Loss situation. Check the parts of the force, keys, keyways are deformed, oil seals for wear and so on. Large-scale maintenance is: every two years.
Ash separator causes cylinder repair worn surface of the skin, the skin is a magnetic cylinder 2-4 mm thick stainless steel plate welded steel. If the skin surface of the tube
No protective layer (also called the wear layer) will not be long worn out you can not use. Affects both production and increased equipment maintenance costs. In the process of using magnetic separator, magnetic sources is
The pulp choose another important component of the magnetic material, the surface of the magnetic source is mounted 3-4mm thick tube made of a stainless steel plate skin, the skin surface is coated with a protective tube cylinder
The wear layer, when the separator drum skin surface wear layer will appear after prolonged use varying degrees of wear, if not repaired in time will lead to the skin surface of the cylinder is worn,
Seriously affect the magnetic separator smooth production.
Magnetic separator in order to safe production, must pay attention to the following points: 1, electrical equipment should always be kept dry, clean and prevent water splashes on electrical equipment. 2 posts
Workers are not allowed to change the excitation current. 3, the host running the process with iron or other non-magnetic conductor contact turntable and magnetic poles. 4, the boot should be noted that after the first water supply
To the mine, and mine shut down after the first stop should note that without water, pay attention to good order. For the separator, the adoption of effective lubrication method that can reduce the wear of the device itself
Loss.
Its separation process is: to mine the ore from the cylinder exhaust ferromagnetic minerals in advance, it will be evenly routed to the mining belt, the belt to the disc by following
Magnetic gap, the magnetic force being weakly magnetic minerals, is attracted to the disk on the tines, and with the rotation of the disc to the belt with the sides where the magnetic field strength due to a sharp decline
And then under the action of gravity and centrifugal force, falls on both sides of the belt trough magnetic products, the non-magnetic product shipped to the tailing end of the belt into the non-magnetic products
The trough.
Magnetic separator is widely used in the timber industry, mining, chemical and other factories in the resource recovery, re-use powder for removal of iron in mitochondria, etc., which can be divided choose
Minerals are metallurgical manganese ore, manganese oxide, iron sands, kaolin, ilmenite, wolframite, manganese, etc., in order to prevent clogging from happening, cylinder built in the mine
There is a weak magnetic poles, which can be pre-discharge strong magnetic minerals in the feed. The main factors affecting the operation of the magnetic field strength, thickness and so on to the mine.
