Raymond mill return air duct dust increase causes

Raymond mill return air duct dust increase is what reason, such phenomena are not common in the milling production, but each failure needs attention, as a professional manufacturer of grinding mills combined with many years of production experience, the increase in return air duct dust is likely to be due to the cyclone collector size change caused by the following we come together to analyze it.

Before understanding the increase in dust in the return air duct, we first come to understand what is the Raymond mill return air duct, what is the cyclone collector, what is the connection between them? Return air duct as the name suggests the main role is to return to the wind, connected between the cyclone collector and classification, to achieve the whole production line wind recycling, grinding process the entire process for the sealing structure has been said many times before, the air volume initiated by the fan, from the mill host snail shell inlet began to enter, during the period of time through the mill grinding chamber, analyzer, conveying pipeline, cyclone collector and other processes, the final cyclone collector and the powder separation by the return air pipe into the mill, and the powder is separated by the cyclone collector. Powder separation by the return air duct into the fan to achieve the recycling of air volume, the above is the introduction of the return air duct and the role of the details.

Below we understand the cyclone collector, cyclone collector is the main role of the collection of finished products, the lower end of the collector for the inverted cone, the upper end of the cone, when the powder with the airflow into the Raymond Mill cyclone collector is a high-speed rotating state, to be separated from the airflow and powder, the airflow with the cone wall contraction to the center of the center to move to the bottom of the cone (since the natural length of the airflow) to form a rotating upward airflow cylinder, which is separated and dropped to collect the powder. Separated from the collection. Due to the upward rotation of the core was a negative pressure state, so the lower end of the collector sealing requirements are very high, must be strictly separated from the outside air, otherwise the powder will be collected under the core of the core airflow to take away, which directly affects the yield of the whole machine, so the lower end of the collector is equipped with a powder lock. There is also an important factor is the height and diameter size of the powder locker, the size of each collector size dimensions are based on the mill model to ensure that the storage of the finished product material is qualified, when the collector pipe diameter becomes smaller or due to plant reasons to arbitrarily change the size of its height, the finished powder powder height is higher than the normal level, when the powder page is close to the mouth of the return air duct, the powder will be although the airflow into the return air duct. It can be seen that the cyclone powder collector, back to the use of the air duct has a lot to learn, in addition to give you a popularization of a little knowledge: conveying pipeline, back to the air duct are connected to the powder collector, but their caliber must pay attention to the caliber of the back to the air duct, strictly speaking, the caliber of the return air duct should be inserted into the early conveying pipeline level position a bit, these things to protect the powder to collect the powder normally does not cause the powder into the back to the air duct of the key.

From this we can according to the cause of the disease, one by one exclusion for the milling production line cure.

In short, the return air duct wind dust increase belongs to a kind of improper production phenomenon, in the Raymond mill production is not common but also expressly prohibited, if found in the production line must pay attention to this kind of problem immediately shut down to check, to be ruled out after the hidden trouble in the resumption of production. This also reminds us, in the installation of equipment, must be in accordance with the provisions of the manufacturer, the installation of illustrations, seemingly insignificant equipment structure in fact, the designer of the multi-party test data.
