Liming Heavy Industry LM Vertical Mill cement production line

LM Vertical Mill more and more widely used in cement production lines, the new cement production line, coal, raw materials used LM Vertical grinding Mill grinding accounted for more than 90%, cement clinker and slag grinding using Li -type milling machines are more and more, so in modern cement plants, LM Vertical Mill has become an important plant processes and equipment, which is a series of fine character of its decisions, some which are purely mechanical technology, the other part of the is a process. LM Vertical Mill is developed from l906 onwards, and so far has been the continuous improvement of the past century has gone through a roller mill by centrifugal force to exert pressure to use spring pressure, and now with the hydraulic pressure pneumatic spring system. By grinding material from the most soft-coal-to moderate hardness of cement raw materials to brittle cement clinker and slag. For the cement industry, the new dry-process technology, the invention calciner, rotary kiln production doubled, and large-scale, making vertical roller mill structure has been continuously improved and large, to meet a kiln with ~ grinding requirements.

In order to meet the cement grinding process production line of coal, grinding cement raw materials, grinding of cement clinker and slag requirements of countries in the world of cement machinery manufacturers have developed their own brand of LM Vertical Mill. According to this demand and to address the industrial mill output and lower energy consumption and higher technical problems, absorbing advanced technology combined with European Liming Heavy Industry for many years design and manufacture of advanced mill concept and market demand, after years of concentrated design improvements, Liming Heavy Industry introduction of LM Series Vertical Grinder Mill, the LM Vertical Mill with a reasonable and reliable structural design, with advanced technological process, set drying, grinding, classifying, upgrade in one, in particular, grinding process in a large, fully meet the customer demand, the main technical, economic indicators have reached international advanced level.

LM Vertical Mill from the main structure of separators, roller devices, disc devices, pressure devices, reducer, motor, shell and other components. Separator thickness is to determine the degree of milling products are important components, which can speed the transmission from the device, rotor, fan-oriented, shell, tapered bucket meal blanking out draft etc., is an efficient, energy-saving and fast classifier device. Roller is a material for rolling mill main components. It was installed in the mill of the bend arm, in the role of external forces, the pressed material in the disc, in the disc's lead, turning roller followed, so that has been crushed and the crushed material. Disc fixed to the reducer output shaft, the upper part of the disc material bed, bed material circular groove, the material is in the ring tank was roller milled. Pressure device is to provide the pressure roller milling parts, which consists of high-pressure filling stations, hydraulic cylinder rod, accumulator etc., able to exert enough pressure roller to crush material. Reducer is the main power transmission components, disc rotation speed is the speed reducer output shaft.

LM Series Vertical Grinding Mill for the new cement production line, in the grinding and classifier space meal has a high circulation rate, so that powder in the grinding process of selection has a very high drying efficiency. Adjustment of the wind through the best guide ring, so that very uniform air containing dust through, so that air consumption (mill resistance) to minimize the same time, maximum output of grinding to achieve the minimum total energy consumption, there is no need to reduce air volume and external recyclable materials to reduce energy consumption. Addition Vertical Grinder also has a line of low cost, construction of low cost, easy operation and reliable drying capability and so on. Vertical mill using gas transportation of materials, in the grinding of materials for large water inlet temperature can be controlled so that products reach the final moisture in the LM Vertical Mill can be drying moisture of up to 12 ~ 15% of the material, even if the is a drying ball mill, drying only water for 3 to 4% of the material. Product quality is stable, uniform particle size distribution. Material stays in the grinding time is short, easy-to-particle size and chemical composition of the product testing and control, product quality is stable. Easy maintenance, through the maintenance of tanks, turn rotating arm, roller sets, lining can be replaced in a very short period of time. Environmental protection, energy saving; little vibration, low noise, low dust, operating a clean environment to meet the environmental requirements.

Car Trouble?

Ok I don't know if it's all in my head but when I apply the breaks I hear this weird noise coming from the back. It sounds like a bucket full of water knocking over (i'm not making this up). I have nothing in the trunk but a box and the spare tire. Can it be the back back rotors perhaps or something underneath?

Depending on your car make you should have drum brakes in the back. Sometimes on older cars water can leak into the drums and will make a swishing sound at times, but this is rare.

Another thing is you may have a hole somewhere where rain water or when you go to the car wash water is getting in the body somewhere. If you do have a place in the trunk for a spare. Check this place out and make sure it isnt full of water where your trunk might have leaked.

Also dont only notice the sound when you stop. Also try feeling to see if your car acts different when this sound occurs. Like does it grind or pull to the right or left. Does it hesitate to stop or stop to suddenly.

Another thing you could try is find a good size hill. Park your car up the hill get out and see if you see any water coming from the rear. Also park it down the hill and do the same thing. You can as well place your hands ontop the trunk over each shock and press down hard 2 or 3 times and see what you hear or how the car acts.
