Mine mineral processing is an indispensable part of modern industrial production. In the whole mineral processing process, ball mill plays a vital role as one of the key equipment. The ball mill is mainly used to crush the mined mineral raw materials to make them meet the particle size requirements required by the subsequent process. While ensuring the safe operation of production equipment, it is particularly important for the safety management of the ball mill room, including the selection and use of the door lock of the room.

A, the importance of mine concentrator ball mill room door lock

1. Ensure the safety of personnel: The ball mill will produce loud noise and vibration when working, which may be accompanied by dust flying. In order to prevent unauthorized or untrained personnel from entering the operation area and causing accidents, it is very important to set up a reliable safety door lock.

2. Protect property safety: high-quality ball mills are expensive, and their internal structure is complex, which requires regular maintenance. Reasonable installation and use of durable door locks can effectively avoid losses caused by theft and other reasons.

3. Meet regulations and standards: According to the requirements of laws, regulations and industry norms related to safety production, mining enterprises must take necessary measures to ensure that all operating environments meet safety standards. Therefore, choosing a suitable door lock system is also one of the manifestations of enterprises' legal responsibility.

Second, the door lock type and its characteristics analysis

In view of the above-mentioned demand background, before choosing specific products, we should first understand several common door lock forms in the market at present:

Mechanical locks: such as ordinary padlocks and mortise locks. The advantages of this kind of products are low cost and easy replacement; The disadvantage is that the security is relatively low (easy to be destroyed by violence) and the remote control function cannot be realized;

Electronic password lock: The device is turned on/off by inputting the combination of numbers, which has high confidentiality but also has certain risks (such as forgetting the password or leaking the password). In addition, some high-end models also support functions such as fingerprint identification to further improve the protection level;

Smart card reader: RFID technology is used to realize non-contact authentication process, which is convenient, fast and easy to manage and track records;

To sum up, it can be seen that each scheme has its own advantages and disadvantages in applicable scenarios, and the specific selection needs to be decided after comprehensive consideration of factors such as actual working conditions and budget constraints.

Third, case sharing-practical exploration of a large copper mine project

There was a serious safety accident in a subsidiary of a well-known nonferrous metal smelting group in China: at that time, a worker accidentally broke into the running ball mill workshop because of the lack of effective physical isolation measures, which caused irreparable loss of life. Afterwards, the company attached great importance to the lessons of this incident, immediately organized relevant departments to carry out rectification work, and introduced a set of solutions integrating intelligent access control system under the guidance of experts:

The scheme mainly includes the following parts:

Set up special passages for important facilities, install high-precision face comparison equipment and strictly check the access authority review process;

Add emergency evacuation indicator lights at the door of each room to guide people to evacuate the dangerous scene quickly;

Push the real-time monitoring screen by using the mobile APP to give managers the latest situation at any time, and dynamically adjust the strategy to deal with emergencies. ...

After a period of stable operation, it is proved that this new model effectively makes up for many shortcomings in the traditional mode, significantly improves the overall operational efficiency and provides valuable reference experience for other peers.

Through the in-depth discussion on the theme of the door lock of the ball mill room in the mine concentrator, it is not difficult to find that the reasonable design and implementation of a set of perfect access control management system can not only effectively protect the life and health rights of employees from infringement, but also help enterprises stand out in the fierce market competition environment and gain sustainable development momentum. I hope that more advanced technologies and ideas will emerge in the future to promote the progress of the whole industry!
