Raymond Mill Afterwind Origin and Elimination Methods

We can know that the wind capacity in the system will increase. However, the volume of the system is limited, if the added wind is not eliminated, the system air pressure will increase. On the one hand, it will infect equipment capacity and product fineness, on the other hand, it may cause air and powder leaking. The afterwind pipe can be applied to remove extra wind.

AFTERWIND ORIGIN

1. The Raymond mill feeding port, maintenance gate and cyclone classifier of the air circulation is under negative pressure, if these parts are not well sealed, some air might be draw in the system.

2. When feeding friable material, some air may be draw in with the material.

3. In Raymond mill operation, the heat will raise the temperature of the system for about 10-30℃. For this, the moisture in the material will be dried into vapour.

4. For the rising temperature, the flowing air will have volume expansion.

AFTERWIND ELIMINATION

We can know from the article above that the wind capacity in the system will increase. However, the volume of the system is limited, if the added wind is not eliminated, the system air pressure will increase. On the one hand, it will infect equipment capacity and product fineness, on the other hand, it may cause air and powder leaking. The afterwind pipe can be applied to remove extra wind.

The afterwid pipe should not be set between blower and classifier, because it may draw in large sum of material. The best place to set the afterwind pipe is the exit of blower.

What Problems May Exist in Run-in Period of Raymond Mill?

No matter traditional R Series Mill, or the latest HC1700, HC2000 Grinding Mill, the new machine need a run-in period for the parts.

No matter traditional R Series Mill, or the latest HC1700, HC2000 Grinding Mill, the new machine need a run-in period for the parts.

The run-in period of Raymond mill is about 60 hours, the period is an important step to ensure normally operating, reduce failure rate and increase service life. But, some users ignored the special technical requirement during run-in period. Now, Guilin Hongcheng will introduce you about the problems in run-in period.

1.Fast wearing
For the processing, installing and adjusting of new grinding mill parts, the friction surface is rough. When operating, the fallen metal fragment will be ground with other material, which will cause more serious wearing. So, grinding mills are easier wore during run-in period.

2.Bad lubrication
The new installed parts have smaller fit clearance, for this, lubricating oil cannot form the oil slick on the friction surface. Lower lubrication efficiency will increase early stage wear. In some serious situations, it may also cause surface tear or occlusion.

3.Parts looseness
Newly produced and installed parts may have deviation in shape and size. During run-in period, the parts are easy affected by shock, vibration and heat, the fastened parts might become loosen.

4.Leaking
For the effect of looseness, vibration and heating, there will be leaking phenomenon in the sealing surface and joints.
