The mill is also called vertical mill. The mill is operated intermittently, and the slag is manually loaded into the iron bowl-shaped grinding disc of the planetary gearbox flender for alstom mill, and is ground by a heavy grindstone, and the slag is crushed due to the weight of the grindstone itself. At the same time, because the distance between the points on the width of the grindstone is different from the central rotating shaft, the linear velocity of each point is different, so sliding friction occurs between the grindstone and the grinding disc, causing the slurry to be crushed and disintegrated.

The advantage of the planetary gearbox flender for alstom mill is that the operation is easy and the equipment is simple. The disadvantage is that the equipment is heavy, intermittent operation, labor intensity, large floor space, and difficult to clean in the factory. Previously, the device has been used more and has been gradually reduced. The mill is an industrial equipment widely used in the selection or rough selection of various ores such as metallurgy, iron selection, molybdenum selection, strontium selection, silver selection and lead selection.

Mill application and advantages and disadvantages

The earliest grinding was spring-loaded with smaller gauges.

Hydraulic large-scale milling, which has been manufactured in recent years, is mainly used to grind raw materials in cement plants, and it accounts for an increasing proportion of raw material production.

Milling is usually carried out by hot air flow during drying. In recent years, the use of suspended preheating kiln and waste heat from the kiln outside the kiln has been mainly utilized. Since the planetary gearbox flender for alstom mill itself has a classifier or separator, the milled air stream containing the fine powder is collected by the dust collector to grind the finished product.

The DBY/DCY/DFY Hard Tooth cylinder Gear Reduction is suitable for transmissions in which the output input shaft is arranged vertically. Mainly used in belt conveyors and other transportation machinery ZDY single-stage cylindrical gear reducer drawings, can also be used in metallurgy, mining, construction, cement, light industry, energy and other general machinery transmission mechanism.

Gravity-free mixers can be roughly divided into two types: ordinary gravity-free mixers, one type of fly-knife type gravity-free mixers, and the latter mainly for one type in which the fibers are cut in the material and then mixed by the flying knife.

Performance characteristics：

The rotation speed of the shaft driven by the cycloidal drive reducer and the structure of the blade will weaken the gravity of the material. With the lack of gravity, the difference in particle size and specific gravity of each material is neglected during the mixing process. Intense mixing movement shortens the mixing time, faster and more efficient. Even if the material has a difference in specific gravity and particle size, a good mixing effect can be achieved under the rapid and vigorous tumbling of the staggered stirring blades.

The gravity-free mixer with single stage cycloidal gearbox can achieve a spray operation of less than 17%, and materials with too much viscosity after adding liquid are not suitable. It can be mixed with solid (powder)-solid (powder) (powder size 300-2000um).According to the production requirements, it is also possible to install a spray and a jacket device to make it a solid (powder)-liquid (mixing and drying equipment with a liquid content <15%).

The mixing of materials with large differences in specific gravity and particle size does not produce stratified segregation. When the solid-solid mixture is mixed at 1:1000, the standard deviation is between 30,000 and 100,000.

The bending machine with single-stage cylindrical gearbox is a kind of equipment for bending and forming a sheet by using a work roll, and can form parts of different shapes such as a cylindrical piece and a cone, and is a very important processing equipment. The working principle of the coiling machine is to make the work roll move by the action of external force such as hydraulic pressure and mechanical force, so that the sheet is bent or rolled. According to the rotation movement and position change of the work rolls of different shapes, elliptical parts, curved parts, cylindrical parts and the like can be processed.

Working principle：

The oil acts on the piston for vertical lifting movement, and the final gear of the main hard tooth surface reduction gearbox drives the two lower roller gears to engage in a rotary motion to provide torque for the rolled sheet. The flat plastic sheet of the coiling machine with cylindrical gearing arrangement passes through the three work rolls (two lower rolls and one upper roll) of the coiling machine, and the metal plate passes through multiple passes by the lower pressing of the upper roll and the rotating motion of the lower roll. Continuous bending (inner layer compression deformation, middle layer constant, outer layer tensile deformation), permanent plastic deformation, roll into the required cylinder, cone or part of them. The disadvantage of this hydraulic three-roll bending machine is that the end of the plate needs to be pre-bent by means of other equipment.

Structural features：

The automatic feeding equipment of the coiling machine is mainly composed of a sheet material trolley, an actuator, a sheet conveying mechanism and an auxiliary mechanism. The sheet trolley is used to place the sheet to be rolled. The main function of the actuator is to transport the sheet to be rolled on the sheet trolley to the feeding platform. The handling of the sheet is mainly applied to the Cartesian robot and the vacuum chuck picking device. In industrial automation systems, it is often necessary to pick and load workpieces, and vacuum chucks are widely used as suction-cup robots.

1. The rotation speed of the rotor of the three-phase asynchronous motor is lower than the rotation speed of the rotating magnetic field, and the rotor winding generates electromotive force and current due to the relative motion between the magnetic field and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to realize energy conversion.

2. Compared with single-phase asynchronous motors, three-phase asynchronous motors have good running performance and can save various materials.

3. According to the rotor structure, three-phase asynchronous motors can be divided into two types: cage type and winding type. The asynchronous motor of the cage rotor has simple structure, reliable operation, light weight and low price, and has been widely used. The main disadvantage is that the speed regulation is difficult.

4. The rotor of the wound-type three-phase asynchronous motor is also provided with a three-phase winding like a stator and is connected to an external varistor through a slip ring and a brush. Adjusting the varistor resistance improves the starting performance of the motor and regulates the speed of the motor.
