Mining equipment industry continues to develop, Henan Yu made what in such a competitive market to survive until now it? Of course, we have our own conduct fundamental. Henan Yu hair beginning to end, a customer-centric, from the customer s point of view to production and manufacturing equipment, our equipment conscience to speak, even in the mining industry, give birth to a low ebb in the case, we still have customers to vendors talk! Which is is the reason for it, because our equipment reassuring, service reassuring, used after not regret it.
Separator is used in the re-use powdered iron removal mitochondria, etc., magnetic separator is widely used in recycling, timber, mining, ceramic, ch emical, food, and other workshops for particle size less than 3mm magnetic iron ore, pyrrhotite, roasted ore, ilmenite and other materials wet magnetic separation, but also for coal, non-metallic minerals, building materials and other materials, iron work, is the industry s most widely used, high versatility One aircraft. Below you about magnetic separation equipment manufacturers to motor common mechanical faults and maintenance description:
magnetic drum separator
1 stator and rotor core troubleshooting: stator and rotor are made of silicon insulated from each other quartet built, is part of the magnetic circuit of the motor. Stator and rotor core damage and deformation mainly caused by the following aspects.
① excessive bearing wear or defective assembly, resulting in the stator and rotor rubs, surface damage to the core, silicon steel and cause short-circuit, the motor iron loss increa ses, the motor temperature is too high. Then the application filing and other fine deburring tool to remove silicon short, clean up after applying varnish and heated drying.
suspension magnet
② Remove the old winding when the force is too large, so Pirates slot skew and flared. At this point the application needle nose pliers, wooden hammer and other tools to be trimmed so bad tooth reset, and there is a gap in the bad reset of silicon added between green shell paper, plastic, wood and rigid insulation material.
③ due to damp and other causes of iron surface rust. Time required sanding clean, clean up after applying varnish.
④ heat generated around the burning core group of grounding or bad teeth. Available tools such as a chisel or scraper clean and remove sediments will melt, coated with insulating paint drying.
⑤ bonding between the core and bas e loose, original screws can be tightened. If the screws fail, the base unit can be re-positioning holes drilled and tapped, tighten the screws.
2 Bearing Troubleshooting: shaft through the bearing support rotation is the heaviest part of the load, and is easy to wear parts.
① Troubleshooting
Operation check: Rolling starvation, you will hear "Gulugulu" sound; If you hear no continuous "Terrier Terrier" sound, may be bearing rims rupture. Bearing mixed with sand and other debris or bearing parts with mild wear, it will produce a slight murmur.
INSPECTION AFTER REMOVAL: first look at the rolling element bearings, inner and outer rims for damage, corrosion, scars, etc., and then hand pinch the bearing inner ring, and to settle bearing in one hand by pushing just outside the circle, if the bearing good and outer rims should be smooth rotation, vibration and rotation without obvious catching phenomenon, stalling t he outer rim without setbacks. Otherwise Description bearings are no longer usable. Left hand jammed outer ring, right hand and hold inside rims, forced to push in all directions, and if felt very loose when pushed, is badly worn.
② troubleshooting: Bearing outer surface rust can erase 00 sandpaper, and then into gasoline for cleaning; or bearing cracks, excessive bearing inner and outer rings chipped or worn, replace with new bearings. Replaced with new bearings, to use the same model with the original bearings.
3 shaft TroubleshootingMagnetic Head Pulley
① shaft bending: bending if not, can be polished journal, slip ring method of repair; when bending over 0.2mm, the shaft can be put in the press, the pressure in the film bends correction after correction shaft polished surface with a lathe cutting; if bent too big, you need to put another one axis.
② journal wear: journal wear little, it would be a layer of chrome plating on the journal and then grinding to the desired size; wear more, can be carried in the journal surfacing, cutting lathe and then polished; If the journal wear is too large, the journal also turning 2-3mm, then car a sleeve, hot sleeve in the journal, and then turning to the desired size
The past two years, followed by a new high gradient magnetic separator and new efficient anti-flotation reagent successful development of high intensity magnetic separation - reverse flotation - roasting joint brown iron ore sorting technology has made significant progress, that is, first through the magnetic - obtain a low impurity content reverse flotation of iron ore, and then through the ordinary roasting or mixed with magnetite concentrate produced pellets of iron can significantly improve product quality, but still high-quality iron materials. We Jiangxi pit iron ore limonite, etc. Experimental resu lts show that the anti-flotation concentrate iron grade can be reached 5% 57, SiO2 content is reduced to about 5%, after the iron grade calcined product may reach 64% or more, and roasting, magnetic separation, reverse flotation combined process analogy, production costs dropped substantially, so that the type of economic exploitation of the value of iron ore, and in 2005 will be put into production. Industrial production over the past practice has a strong magnetic beneficiation process, strong magnetic separation - positive flotation, but because of the nature by limonite (extremely muddy), high intensity magnetic separation device (right-20μm iron minerals recovery than Poor) and flotation reagent constraints, sorting index is poor, while reducing magnetic roasting - weak magnetic beneficiation process cost is high, so the class of basic iron ore has not been effectively utilized. Limonite ore magnetic separator magnetic roasting processes are restored - the weak magne tic separation, high intensity magnetic separation, re-election, flotation and joint processes. In order to improve the recovery of fine-grained iron minerals, was conducted using lignite as a reductant and fuel kiln roasting technique semi-industrial tests, flocculation - intensity magnetic separation technology industries, such as testing, have achieved good results.
Widespread market separator device is Yu Fa Machinery gravity respected products, gathered in the existing high-tech products in the market, you want to become an overnight success is very difficult thing, but only determined to create will win a sunny day . Yu Fa Machinery separator is designed for mining beneficiation industry design of a mineral processing equipment, it is mainly used in addition to iron work or mix different types of mineral resources among the beneficiation process systematization, which has been incorporated into a mine irreplaceable Among the mineral processing industry, beca use it has a foundation conquering beneficiation conditions:
Magnetic system used in all high-performance NdFeB rare earth materials and making high-quality ferrite materials, a cleverly open magnetic circuit design, drum table of maximum magnetic induction constituency more than 0.8T, the magnetic field strength is a conventional machine 3 -5 times, sub-district of electromagnetic field strength can reach the level of intensity magnetic separator. Durable stainless steel cylinder by sorting refined.
Mineral separator equipment sorting through vibrating feeder evenly into the separation tube to the upper part of the rotation of the cylinder barrel stripped non-magnetic materials, magnetic materials subject to strong magnetic force attracted to the cylinder, with the sub-ore board easily and accurately the magnetic, non-magnetic material separation. Beneficiation process professional, rational, efficient, high-quality performance.
High quality magnetic separator device is a highly coordinated operation equipment, which appeared in a number of specialized processing production line process among the available refractory materials, chemical materials, grain and oil machinery, abrasives, ceramics, metallurgy, cement , powder metallurgy, rubber, minerals and other materials in addition to (elect) iron work to use, and with Raymond mill, grinder, supporting the use of a ball mill, and magnetic separation - flotation, magnetic separation - re-election is nearly Some years, the mainstream dressing mix process, the effect has been made mining beneficiation industry recognition, and many have been successfully applied experience.
Because limonite rich water of crystallization, so using physical beneficiation of iron ore grade is difficult to reach 60%, but after roasting larger and substantial progress due to burning of iron concentrate grade. Moreover, because the crushing grinding limonite easily in the proce ss of clay, it is difficult to obtain a higher metal recoveries.
Brown iron ore pit we were selective flocculation - intensity magnetic separation technology industry test results show that iron metal recovery can be increased by 10 percentage points or more, but because of selective flocculation flocculation process equipment and control of the premise of not pass without energy industry.
