Ningxiang, ruled in the Three Kingdoms, Jianxian in the Northern Song Dynasty. It is located in the golden triangle of Hunan's “Middle Five Regions and One Corridor†in the northeast of Hunan Province. It is the key to Changsha to Xiangzhong and Xiangbei. It has good location advantages and convenient traffic conditions. It is located in Chang (Sha) (E) (Xiang) The three major tourist circles of the Tan Golden Triangle, Wulingyuan and Dongting Lake are connected to the east, the ancient city of Changsha, the Xiping Zhangjiajie National Forest Park, the south to the hometown of Lushan celebrities, and the north to the vast 800-meter Dongting. â€
Yin Bo, a customer of Ningxiang, Hunan Province, is an authentic individual earthwork contractor. In the industry, there are many years of civil engineering experience, and there is considerable influence in the local area, a large group of friends engaged in earth contracting projects.
From the rental of excavators, Yin Boss has now turned into a self-use excavator and began to develop into various types of infrastructure construction, such as repairing rural roads, highways, hydropower stations, reservoir construction, and high-speed railway foundation construction. This year, Yin Conghui’s civil engineering projects have reached three: the civil engineering of Ningxiang Food Company, the civil engineering of Xiangya Affiliated Hospital of Hunan Province and the civil engineering project of Ningxiang New Airport.
Because of the schedule requirements, the frequency of use of the machine is very high, many excavators are full-load work, and the performance requirements of the machine are very high.
In September 2016, he listened to a friend who said that Liebherr's products are fast and fuel-efficient, and that there are few faults. The accessories are good to buy and the after-sales service is also in place. Then we purchased a R920 device from our Hunan agent. At present, the average working time of this machine is more than 8 hours per day, about 60 hours a week, and it has been working for more than 200 hours.
After using the device, Yin Boss praised the machine:
The loading speed of the machine is very fast (the last 8 rounds always like to wait in line for him to wait)
Strong strength (some other 20-ton machines do not work hard, the R920 is always competent)
Fuel saving (15-16 liters / hour)
Comfortable operation (hands are open)
Only personal experience has the right to speak. Yin Boss has also made a fine account in private: Liebherr's excavator has many advantages in such a working environment. On the one hand, it is fuel-saving, the same working conditions, compared with other brand products, the product fuel saving rate can reach 10%-15% or more, and the fuel cost is about 100,000 yuan in one year. The second aspect is less maintenance costs. The machine rarely has problems and is mechanically skinned. Even if there is a malfunction, the price of the accessory is competitive compared to the same grade excavator. The most important maintenance personnel come in time to deal with the fault quickly and not delay the construction period.
Since the selection of the R920, Yin Boss decided to phase out the other 20 tons of excavators in the future, all replaced with Liebherr equipment. The superior performance of this equipment also attracted the interest and attention of other bosses on the site. In addition to bringing real economic benefits to the boss, Liebherr equipment has made him face in front of his friends, proving that his original choice was right - Liebherr equipment is indeed trustworthy! Made in Germany is well-deserved!
The Trommel Screen , also known as rotary screen,compost sieve or drum screen, is an essential unit which is used mainly in the mineral and solid waste processing industries. It consists of a motor, reduction unit, cylindrical drum, screen frame and sealing cover, which is normally elevated at an angle at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized material smaller than the screen apertures passes through the screen, while the oversized material exits at the other end of the drum.
Trommel screen can be used in a variety of applications such as classification of solid waste and recovery of valuable minerals from raw materials. Trommels come in many designs such as concentric screens, series or parallel arrangement and each component has a few configurations. However depending on the application required, trommels have several advantages and limitations over other screening processes.
