Rim cleaner advantage: Strong removal of stubborn brake powder attached to the hub.Wheel hubs that have never been cleaned and maintained can also be maintained in a short time. The room is clean and can be used on the surface of glass. Removal of stubborn stains and oxides adhering to glass surface.
As for rim&tire clean, using iron cleaner and rim cleaner , using chemical sprayer bottle or foaming sprayers to spray, together with wheel cleaning brush .
And then wheel coating and tire wax ;For coating, the accessiores included coating applicator, sudue cloth .
For tyre protect, there are two types of wax: water-base, oil-base. using wax applicator and spray bottle to work :

Iron cleaner: Reaction only with iron powder and rust, not through. Over-corroded iron powder, rust, but solid. The transformation of liquid iron into liquid iron can be thorough. Dissolved iron powder, rust, in rusty parts. Produce more obvious chemical reactions.
This was successfully developed by units such as Shenzhou in the early 1970s, similar to the Australian Waman-type flotation machine.
1. YJB rod type flotation machine structure and working principle The stirring aerator is composed of 12 inclined round rods, so it is called rod type flotation machine. The structure of the machine is shown in Figure 1.
The rod type flotation machine has two types of a DC tank and a suction tank. Main components such as hollow shaft (spindle), rod wheel, boss and curved flow plate are installed in the DC tank. The DC tank can not draw the slurry from the bottom, only the flotation, also known as the flotation tank. The suction tank is equipped with a suction wheel at the lower part of the rod wheel, which can suck the slurry from the bottom like a centrifugal pump. In the roughing, selection, and sweeping operations, the suction slot is required.
When the DC tank is working, the rotation of the inclined rod wheel below the hollow shaft causes the slurry to strongly rush toward the bottom of the groove along a certain cone angle, so that a negative pressure is formed in the lower part of the inclined rod wheel, and the outside air is passed through the hollow shaft. Inhalation. Under the action of the slanting rod wheel, the slurry is thoroughly mixed with the air, and at the same time, the air stream is cut and dispersed into fine bubbles. The boss acts as a guiding mechanism, so that the slurry gas mixture rapidly rushes toward the bottom of the groove, moves to the periphery of the groove body through the steady flow of the arc-shaped steady flow plate, and is evenly distributed in the groove, and simultaneously turns the rotating slurry gas into a flow. A mixed stream that tends to move radially in a radial motion. The steady flow of the slurry is gradually rising from the bottom of the tank to the liquid level. Thus, the slurry mixture exhibits a special w-shaped trajectory in the tank, which makes the ore surface relatively stable. The mineralized bubbles float up to the foam area and scrape out to obtain a foam product.
2. Main features The main feature of the rod flotation machine is to form a gas agitator group with a slanting rod wheel, a boss and an arc steady flow plate.
(1) Slanting rod wheel. It consists of cast iron casting together disc 12 and a conical rod evenly distributed configuration (FIG. 2A), can be rubber lined to increase the wear resistance. Each of the rods is inclined at an angle of 45 degrees from the direction opposite to the rotation of the rod wheel, and is expanded outward from the top to the bottom to a cone angle of 15 degrees. This structure makes the linear velocity of the oblique rod larger as it rotates, thereby causing a strong agitation effect, and forming a downwardly inclined gas slurry to be sprayed around the bottom of the groove, so that density and granularity can be avoided. The thicker mineral sinks at the bottom of the tank.
Since the agitator can prevent the bottom of the tank from sanding and the dead angle is small, the volume of the flotation tank can be fully utilized, and the volume utilization rate is remarkably improved. Since the pneumatic slurry has a W-shaped motion trajectory, the installation depth of the rod wheel in the groove can be reduced, which can be easily started after a long time of parking, and is also beneficial to increase the amount of inflation, reduce power consumption, and improve the technology of the flotation machine. performance.
(2) Boss and curved steady flow plate. The structure is shown in Figure 2b and their function has been as described above.
(3) Suction wheel. Also known as the lifting wheel, it consists of four curved blades with a height of 50mm and two upper and lower discs, and is connected to the main shaft through a short shaft, and is installed in the lower part of the suction rod wheel for sucking the slurry. This is a unique component of the domestic rod type flotation machine.
(4) The trough is shallow. The groove depth of the rod type flotation machine is only 2/3 of that of the XJ type flotation machine, so that the static pressure of the slurry received by the rod wheel is small, and the outlet speed of the inflated slurry is larger when the rod wheel rotates, so the flotation The suction capacity of the machine is correspondingly increased, and the power consumption is reduced.
At the same time, the flotation machine has the advantages of simple structure, convenient operation and maintenance, high bubble dispersion, many opportunities for slurry gas contact, uniform mixing, and fast flotation speed.
XJB rod flotation machine for medium and small mineral processing plant density, coarse grained metal ores, flotation can be employed in various operations, especially lead, zinc, copper, molybdenum, sulfur, and silica sand The best results are selected.
The flotation machine is mainly produced by the mining industry. The technical parameters are listed in Table 1. The mass and length of the different groove numbers are listed in Table 2, and the external dimensions are shown in Figures 3, 4 and Table 3, respectively.

BK1 flotation machine. The first tank adopts XJ flotation machine as the suction tank, and the subsequent tanks adopt the Denver DR flotation machine as the DC tank. Because of the characteristics of self-priming, inflatable and horizontal configuration, it overcomes the foam used in the return of the mine. The pump and the number of slots need to be arranged in steps and the air intake is small.
The flotation machine is produced by various mines and has a specification. The technical performance is listed in Table 4.
