Distinctive technology of iron ore dressing line As for iron ore drying process, we will without doubtly use dryer. In the vacuum operation can reduce wet points boiling point and material the drying temperature, steam not easy leaked out, and so, vacuum drying machine is suitable for drying of material, easy oxidation, explosive and poisonous material and wet points to the occasion of steam recovery.According to the operation method can be divided into intermittent and successive.According to dry medium can be divided into the air, black or other dry medium. Such as hot air stove, black, producer gas generator, etcAccording to sports (material mobile and dry medium flow) way can be divided into and flow, countercurrent flow and wrong.According to the heating mode, drying machine, the conduction of streaming into type, FuSheShi, dielectric type type etc. Drying equipment common sense: common type of dryer in our country are common spray dryer, and the air is dry machine, fluidized bed drier, braising drying machine, fluidized bed drier, such as spray granulation. Braising drying machine of the spray drying is drying equipment one of the most advanced equipment. At present, there are a lot of businessmen can provide this type of equipment.
Laser printers use a technology similar to that used by photocopiers. A laser printer is mainly consists of a photosensitive drum which is electro statically charged and is able to attract the ink to form a pattern that will be deposited on the sheet of paper. They operate as follows: An ionizer sheets of paper load positively. The laser supports positively drum at certain points through a rotating mirror. Thus, the ink in the form of powder (Toner), negatively charged, is deposited on parts of the toner having been previously loaded the laser. When drum rotates ink is sprayed on the paper. A heating wire (called coronary) than fix the ink on paper. Thus, the laser printer, with no mechanical head, is fast and quiet.
Some of the dressing plants will send the fine ground ore powder directly into a magnetic separating machine for magnetic separation (classifier). The mineral powders that come from the ball mill equipment are not graded and come through the magnetic separation directly, so that the particle sizes of ore powders are uneven. A distinction is made in both technologies for laser printers: "Carousel" (four passes) or "Tandem" (single pass).
Carousel: With the technology carousel, the printer makes four passes to print a document.
Tandem: A laser printer leveraging technology "tandem" file each color in one pass, toners are arranged in parallel. However, this technology has a higher cost, the mechanics is more complex. It is therefore reserved in principle for color laser printers for medium or high end.
