effective utilization of resources slag magnetic separator magnetic effect

Slag magnetic separator magnetic mineral particles only after magnetic separation. Weakly magnetic minerals and the ferromagnetic minerals due to its chemical composition and crystal structure is different, it is different from the magnetization characteristics

Composed of many magnetic domains, according to market forecasts, our magnetic separator when the 2008 market size of about 11 million, in 2009, China s coal mining and washing industry, the total size of the construction

An increase of 53.1%, 84.4% of the net increase in built size, showing a strong momentum of growth. If the reduced magnetization H, J magnetization decreases compared, but not along the

The original curve, but is decreased along the curve than the original, if the magnetizing field strength H is reduced to zero, J does not drop to zero, while retaining a certain value Jr, the number of

Value is called remanence, a phenomenon known as hysteresis, J in order to reduce to zero, and needs a reverse magnetic field, the strength of the coercive force Hc is called.

According to various minerals than the susceptibility differences, and different magnetic field strength slag separator machine, generally divided into three categories. Weakly magnetic minerals than the magnetic

Coefficient of 15 - 500 * 10-6 cm 3 / g, such as hematite, limonite, and other methods using magnetic separation recovery. Strong magnetic minerals than the susceptibility greater than 3000 * 10-6

Cm 3 / g, such as magnetite, pyrrhotite, etc., with a weak magnetic separation equipment that is able to effectively separate and gangue minerals. Magnetic minerals than the susceptibility of 500 -

3000 * 10-6 cm 3 / g, such as semi-illusion hematite and ilmenite, etc., with the magnetic field magnetic separation equipment for sorting.

Slag separator Henan Yu Fa Machinery Co., Ltd. is slag beneficiation designed magnetic separation equipment, mineral processing equipment for slag traditional screening inadequate Yu licensing

Slag separator greatly improved the appearance of slag screening efficiency, improve the efficient use of resources, but also by users unanimously approved, are detailed below under the slag magnetic

Sorting machine should be noted that the use of the principles and maintenance measures:

⊙ focus associated with the magnetic machine before and after the device task conditions, especially in front of weakening, magnetic knife holders slag and other operations must be running. Timing replace oil.

⊙ dielectric plate pleaded not string is not blocked, adhere cl eaned once 20 to 30 days, regular replacement dielectric plate (for example, one year or six months depending on the condition of the tooth plate abrasion), and focus on pressure

Cover screws to tighten.

⊙ task focused oil and cooling oil temperature rise is too high to be reported to the workshop director, in order to adopt the necessary measures, such as downtime. Gearhead temperature super-

Limit should immediately report the workshop leader, parking View disposition.

⊙ focus on investigating the oil pressure gauge, pressure gauge, voltmeter, ammeter pointer whether sensitive tool holderreading ability to meet requests, identify problems and timely disposal to find relevant personnel

.

The so-called slag separator working gap, that is the spacing of the cylinder and the tank. This spacing is the size of concentrate quality factors affecting choose ano ther one. If the slag machine

The gap is too small, that tube skin and too close to the tank, the slurry flow through only did he not affect the processing capacity, and because space is too small, it will make regardless of the size of the magnetic

Particles will get ample opportunity to breathe drum skin. Mainly due to the magnetic field from the pulp is too close, the magnetic field caused by the high strength. However, to reduce tailings grade increase the recovery rate

Is good.

If the spacing is too large, can only make a strong magnetic pick up particles, weaker on the election does not come up, Wet Magnetic Separator although concentrate grade, but also increases the tailings grade

, Reducing recovery. Therefore, adjust the working gap slag machine is very important. Field production will generally need to be adjusted according to the working gap in t he range of 35-60 mm

, The working gap angle bracket can be adjusted to change the bottom gasket gap size.

Plastic Additives

The main performance
The main requirements of the plastic additives are:
① Efficient: applications in plastics processing and can effectively play its proper function. Selection should be based on the additive mixing with the comprehensive

performance requirements.
② Compatibility: synthetic resin with better compatibility.
③ Persistence: in the plastic processing and application process is not volatile, non-bleeding and non-migratory and non-leaching.
④ Chemical stability: in the plastic processing and application process does not decompose with the synthetic resin and other components of the chemical reaction.
⑤ Non-toxic: no toxic effects on the human body.
⑥ low prices. Add a way to add an additive depends on: the physical form of synthetic resin and melt characteristics; additives physical form and concentration;

additive compounds, the dispersion and solubility; compounds, the ultimate physical condition. Add o clock

High-speed mixing, mixing and extrusion processes. The effect additives may be added, in addition to depending on their mechanism of action, but also depends on the

correct order of addition.
Type
Plastic additives according to their specific functions can be divided into seven categories:
① to improve the processing performance additives such as heat stabilizers, lubricants and the like.
② improve machining performance additives, such as plasticizers, toughening agents, etc.
③ additives improve the surface properties, such as an antistatic agent, a coupling agent.
④ improve optical performance additives such as coloring agents. ⑤ improve the aging properties of additives, such as antioxidants, light stabilizers.
⑥ reduce the cost of plastic additive , such as extenders, fillers and the like.
⑦ impart other specific effects of additives such as blowing agents, flame retardants, fungicides and so on.
Additive is dispersed in the molecular structure of the plastic, the plastic will not seriously affect the molecular structure, and can improve the properties or

reduce the cost of chemicals. Additive to be added, can promote improved plastic substrate processing, physical, chemical and other functions and increasing

Substrate physical and chemical properties.
According to the pvc additive to improve functional differences, there are many different titles additives.
Specifically, from the increase of the processing characteristics of the substrate, additives include: ① Liquidity: sl ip agent; ② thermal stability; ③ heat

stabilizers, antioxidants; ④ dispersion: processing aids, dispersants; ⑤ compatibility : Compatible, coupling agents; ⑥ melt strength:

Bridging agent, thickening agent.
Increasing the substrate from physical and chemical properties of the additive include: ① rigidity, strength: fillers, nucleating agents; ② shock resistance: the

impact modifier; ③ Heat resistance: fillers, nucleating agents; ④ flame Xing: flame retardants; ⑤ Weather resistance: UV stabilizer stability

Agent; ⑥ conductivity: Antistatic conductive coating filler; ⑦ Color: pigment; ⑧ Flex: plasticizers processing oil; ⑨ density: foaming agent; ⑩ Transparency:

nucleating agents, health of: antibacterial agent. Additives are mainly the following categories: 1, antioxidant

Agent (Antioxidant) unsaturated double bonds in the plastic by an oxygen atom, the invasion of heat and light, free radicals cause fracture, thereby causing a chain

reaction, the molecular chains or the formation of the crosslink, resulting in reduction in strength of plastic products or brittle. Antioxidants function

Is that the delay can be due to oxidation and decomposition of the plastic, extending the life of plastic products.
Used in the plastics industry antioxidants can be classified according to function: (1) the oxidation chain reaction inhibitors: eg alkylphenols (Alkyl phenol),

butylated toluene (Butylatedhydroxytoluene referred BHT), aromatic amines (Aromatic amines),

Phenyl-B-resistant amine (Phenyl-B-Naphthylamine), alkyl of Kun (Alkyl Quinone), an alkenyl group of bisphenol (Alkylene bisphenol), alkylphenol sulfide (Alkyl

phenolthioether), salicylate, phenyl means (Phenyl salicylate )

And so on. (2) peroxide decomposers: alcohols such as Liu acute thioether sulfur propionate (Thio propio nate ester), an organic phosphorous compound.

как можно ослабить или блокировать магнитной силы

Ослабить магнитного можете победить, жареная Кстати, его основной целью является, чтобы магнит силовые линии магнитного поля достигают хаоса ослабить роль магнетизм, если у вас есть лучше, вы можете!
