With the development of aluminium industry, the red mud all over the world at present, the annual emissions of about 70000000 tons, emissions China red mud a year more than 7000000 tons, long-term occupation of land, resulting in land alkalization, groundwater contamination, harm people's health. So many of the red mud yard not only occupy land, and red mud heap barren, easy to produce dust and landslides, destroyed the ecological environment around the aluminum plant.

With the development of stone crusher technology is improving, the yield also increased year by year, the use of advanced production technology, but a by-product of red mud in the production process of alumina -- is always a problem to be solved.Many people do not know can recovery from red mud, after recovery from red mud can be sent to the red mud treatment plant during processing.

At present, the production of alumina red mud produced did not take treatment measures properly, and the years of production, although carried out a series of recycling attempt, but are more or less problems. Now the domestic Alumina Ltd to each as an example, the red mud dump 16000000 tons of red mud have been piling into Pyramid type more than 70 meters high, causing serious pollution. How to handle and use these alkaline red mud waste, has become a hot problem concerned by society.

The normal work of the calcium carbonate equipment, should always pay attention to whether the normal working state of calcium carbonate equipment. If abnormal, should immediately stop maintenance. The device starts the normal again after the inspection of nozzles each calcium carbonate plant without clogging or fall off and the temperature of the motor and voice, always observe the exciter sound, calcium carbonate equipment four cases observation angle amplitude is consistent, the triangle belt is loose or fall off, always observe the effect of dehydration and dielectric. 

Special attention will be on a sieve material discharging end rear can stop should stop time. Observation of sieve through resonance point and other equipment are collision free parking, when found the following must immediately stop. Encounter endanger personal safety or the safety of equipment conditions, should be calm. 

When the operating personnel in operating the equipment should pay special attention to the above points, avoid the occurrence of safety problems of personal safety and equipment, as far as possible to reduce unnecessary losses. Therefore, the operator should accept the relevant skills training, with the technology level of the corresponding. In the safe use of calcium carbonate plant problem, the operating personnel must not be careless.

vertical roller mill equipment boot sequence for the good functioning of the device has a great impact, in order to help the device to work better, this article describes the boot sequence and boot device should be carried out before those operations. Ultrafine grinding equipment is an indispensable equipment in the fine powder production engineering. The installation and maintenance of the equipment is a problem that people attach great importance to, because it has a great relationship to the normal operation of the equipment. The same operation of the equipment Built on the correct boot sequence of the device, this article mainly describes the following sequence of vertical roller mill. vertical roller mill is able to process more than 400 mesh superfine powder mill, the device uses a high pressure spring setting grinding device, the grinding force in the production equipment increased a lot, which is the production efficiency of equipment The improvement is greatly helped, the equipment in the production line are generally equipped with hoist, feeder and other equipment, these equipment to complete the production process of vertical roller mill, equipment before starting a lot of precautions.

The work of trapezium mill will be affected by the environment. This article will introduce what to do in order to ensure the normal operation of the equipment in hot weather.

Most of the spring has passed. Temperatures in many areas have begun to pick up. They will quickly enter hot weather. Under such conditions, the work of trapezium mill will inevitably be affected, and if the equipment fails to work properly, then for the entire In terms of production engineering, its production efficiency will be greatly affected. How can we ensure the normal operation of trapezium mills in hot weather?

The generation of trapezium mill is that in order to meet the continuously refined production requirements, the milling industry has also been well developed since its inception, and has continuously incorporated new production technologies. However, weather and environment cause it to be generated at any time. The influence is inevitable. For example, in hot weather, ultra-fine mills produce a certain temperature when they are produced, and the outside temperature is also high, which can cause the device's own temperature to dissipate.

When using the trapezium mill, we must promptly solve the problem of the roller.  The grinding roller is a very important part of the trapezium mill, and its damage will lead to the suspension of the entire production process.  

The point is the quality problem of the ultra-fine mill itself, because the core components such as the grinding roller are wear-resistant parts during production, so in order to better extend the service life, it is necessary to choose a production material with better wear resistance. , but many manufacturers in order to obtain greater production efficiency, the material used, wear resistance did not reach, so trapezium mill roller wear resistance is low, in the production will be prone to problems, so choose a better quality Equipment is also very important.

The article mainly analyzes the problem of grinding roller wear when trapezium mill work. The main reasons for introducing the above two aspects are as follows: First, quality, and first, operation, so we need to have more mill capacity. Good performance requires good equipment selection and reasonable operation.
