Mill sealing is an important basis for judging the quality of excellent

A lot of mechanical equipment sealing is an important criterion for judging the quality of the equipment, for the grinding mill equipment working principle performance of special machines is more so, good sealing performance is an important indicator of the basis of the assessment of the quality of the equipment, sealing unqualified will bring a lot of equipment failures, poor equipment performance, low productivity, the following step by step to understand the importance of sealing, sealing the main parts of the sealing, sealing measures for improvement. The following is a step-by-step guide to the importance of sealing, the main parts of sealing, sealing improvement measures.

The entire milling production line sealing have strict requirements, some parts of the requirements are more stringent, such as the mill host conveying pipeline, grinding roller assembly, unloader powder locker, etc., each part of the sealing effect is different, the impact is also very different, we one by one to understand in detail.

Mill host and conveying pipeline, host that is, the grinding room is the core of the entire production line, the main production activities are completed here, material grinding, transmission, etc., grinding room sealing requirements reasonable and accurate, sealing does not mean completely closed, such as the feed port, air inlet, etc. are connected to the outside world, the material will be carried with the amount of wind with a reasonable design, and will not appear in the discharge port back to the material is serious, the material sucked back, etc., and conveying pipeline is required to be strictly sealed. The conveying pipe is required to be strictly sealed, the sealing of the pipe is the key to ensure that the powder transportation, conveying pipe leakage phenomenon, not only will affect the production of the surrounding environment, but also cause the transmission production line positive and negative pressure imbalance, the material can not be transported, low yield settings do not powder and other phenomena.

Grinding roller assembly is a combination of grinding rollers, bearings, shafts and other accessories, grinding rollers grinding ring is the only grinding parts, the principle of action is to rely on the bearings to achieve the rotation to achieve the grinding effect, bearings are fragile and lubrication requirements are stringent, the protection of the bearings is the key to grinding rollers and other wear parts, the sealing of the grinding roller assembly can effectively eliminate the dust into the reduction of lubricant contamination, not reflected by the user in the early Raymond mill damage rate is high, mostly due to the grinding roller assembly sealing is not good, the majority of explanations Early users reflect Raymond mill damage rate is high, mostly explained by the poor sealing of the roller assembly, a large number of powder into the cause, OCP now produces all the milling equipment at least 5 sealing device, the effect is excellent, the damage rate is significantly reduced.

Unloader lock powder is the final gate in the material transfer, many people are not very concerned about this, that the powder if through the above grinding and conveying links, here must not be a problem, in fact, this key is very wrong, the reason why the finished product collector to achieve the collection of powder rely not only on the powder's own gravity, an important is to lock the powder unloader a good sealing, if the sealing is not good, the powder is prone to cause If the seal is not good, the powder is easy to cause suction, the discharge port dust and other serious consequences, the locking powder collector is to control the air into the bottom of the collector, to ensure the stability of the normal powder exclusion.

It can be seen that different grinding parts of the sealing principle and role are not the same, but the purpose is the same in order to protect the production of stable and efficient, the improvement of the sealing of the grinding machine mainly depends on the grinding plant precision and other production processes, advanced technology, which is the key to precision between the parts of the equipment with a close match in order to ensure the stability of the production of the grinding machine under the premise of improving technology, equipment structure, the sealing effect is improved to a better state, the grinding machine can be used in a variety of different ways. The effect of improving to a better state, grinding equipment sealing manufacturers accounted for most of the factors, but there is a small part of the need for the user to cooperate, often overhaul and repair for the mill, is also an important factor to protect the sealing of good.
