Application of Lipp Silo in Coal Industry

The Application of Lipp Silo

The technology of storing coal in steel silos has been used in some power plants and coal mines. Coal storage silo usually use cement silo or steel silo, at present, there are more application of cement silo. However, cement silo take a long construction period and high investment. Lipp steel silo as the leader of steel silo, has been gradually used in grain and oil, brewing, building materials, environmental protection, chemical industry, energy and other industries, such as YIDONG GROUP, Ningbo Kangli Glass Co.,ltd, etc.

Lipp Silo is well-known by the technology invented by Germans named Mr.Xaver.Lipp. In 1960s and 1970s introduced to China. In 1980s start application in the field of cement building materials, now widely used in cement plant, grinding station, hydropower station, thermal power station, cement transfer depot, etc.

Lipp Silo Technical Performance and Features

Technical Performance

1. Good integrity and long service life. Lipp Silo in the whole process of construction using the special equipment, greatly strengthened the carrying capacity of the silo body, so the silo has high integral strength, good stability and excellent seismic performance.
2. High sealing performance, prevent rain and leakage. Lipp Silo due to it’s five layer undercut technology, so it has high sealing performance, can prevent rain and leakage. Can prevent cement, fly ash and other materials caking and hardening.
3. Short construction period, low cost.
4. Using field construction, Lipp equipment can provide a shaping speed of 3-5m per minute, So the construction period is short.  A coal silo with a high of 15m could be constructed within 8-10 days. Cost-effectiveness can be achieved for light sheets are used for the whole silo which made it just as heavy as the concrete silo.
5. Covers small area, easy to manage. Lipp Silo’s height and diameter can be arbitrarily selected within a larger range. comparably small coverage that could narrow the two silo separation distance down to 500mm for maximized space utilization.

Technical Characteristics

The construction technology of Lipp Silo is the world's most advanced steel silo construction technology. It’s construction method is unique: When construction, put The 495mm width of the coil from the decoiling machine into forming machine rolled into the desired geometry then through the bending machine. During the rolling process, the silo wall undercut a 30mm-40mm spiral convex strip, which is 5 times thicker of the material (see the picture below). Install stiffener in the silo,structurally strengthen the strength of the silo.
