Nanjing Jiangning District Country Garden Phase VI site, Liugong CLG948E hydraulic excavator is working in an orderly manner. Mr. Cao, the owner of the machine, said that Liugong 948E, 950E and other six Liugong excavators have been serving on the construction site for half a year, mainly responsible for the earthwork and crushing work on the construction site. Due to the stable and powerful performance, everything was smooth during the construction period and was highly recognized by Country Garden. What type of condition requires crushing 1, mountain, quarrying 2, secondary crushing 3, the road is broken 4. Municipal demolition Liugong, which carries many praises, has gathered the research and development achievements of hundreds of experts from Japan, Germany, Britain and the United States in the background of the weak decline of the domestic construction machinery market. After many years, it has carefully built high-end positioning, leading domestic and international. The first-class Liugong fifth-generation E-series excavator. The Liugong CLG948E crawler hydraulic excavator has top-level configuration and application of new technology. The product quality and technical level have reached the first-class level in the industry, and it has outstanding performance in terms of crushing. In-depth study of heavy engineering users such as mines and quarrying Users of heavy engineering are generally involved in the construction and maintenance of roads, water conservancy, railways and urban railway systems, and military, and there is a greater demand for medium and large horsepower excavators. The users involved in quarrying and concrete engineering are the collection of building materials, marble or granite blocks. They need high-reliability, high-efficiency, strong service and spare parts support capabilities, and medium-horsepower excavators equipped with crushing tools. The hydraulic hammer is a hitting tool that is installed at the front end of a hydraulic excavator (loader) to convert hydraulic energy into mechanical energy. It is used to strike large, hard and brittle objects. Compared with general construction conditions, crushing operations are more demanding on excavators. The special nature of the working conditions requires the anti-wear and corrosion resistance of the products to the utmost. The group characteristics of the crushing operation are also characterized by “main operating equipment, heavy-duty operations, unit users (outsourcing to retail investors), and large demandâ€. Their demand for equipment is: high reliability, operation High efficiency, strong service and accessories support, and high horsepower. Engine and hydraulic system The hydraulic system of Liugong 948E excavator adopts the mature Kawasaki hydraulic parts to optimize the working speed of the working device, reduce the unnecessary throttling loss of the hydraulic system and improve the working efficiency. At the same time, the engine and the main pump match the control technology to fully utilize the engine power. Rational use of diesel engine fuel economy. Liugong's advanced IPC control system, 6 operating modes, 12 throttle positions for operator selection, one button can be directly cut into the breaker mode. The United States imported Cummins QSM11 engine Liugong and Cummins have a long history of cooperation. In particular, at the end of 2011, the two parties established a joint venture company with a ratio of 5:5. In June 2012, the foundation of the joint venture company was laid. This cooperation undoubtedly injected strong and high-end resources into the power system of Liugong excavator. In order to enhance the reliability of the diesel engine system, the 948E excavator uses the original imported Cummins QSM11 excavator engine. QSM's Quantum electronic control system optimizes engine performance, enhances engine protection, provides complete programming options, and is superior in engine. Fuel economy. Cummins is the world's largest independent diesel engine manufacturer with an annual output of more than 900,000 diesel engines to meet global emission regulations. The QSM11 engine is a specially developed model that optimizes the matching of engines and excavators according to actual working conditions. Reduce fuel consumption. And because of Cummins' strong service network, it also provides guarantee for engine maintenance services. It is also worth mentioning that the engine damper adopts a new structure, and the damper protection device increases the limit function of the bowl protector. After the failure of the rubber length, the important components such as the fan and the oil sump are also protected. Component enhancement reliability The special work of crushing determines the high reliability of the equipment, so its components must also be highly durable. The 948E measures the thickening of the key parts of the working device and the strengthening of the reinforcing plate to ensure the firmness and durability of the working device and the X-shaped walking frame. The anti-collision rotary platform is completely suitable for working in harsh working conditions; the enhanced crawler And the roller; excellent large cooling system. Cab: protects the operator when the machine is tipped over For the user, the security of the device is crucial. The 948E excavator has a tubular framed cab, all of which pass the rigorous and stringent safety performance test and are CE certified. The loading is carried out from the lateral, longitudinal and vertical directions of the cab, so that the operator can be protected even if the excavator is tipped over. In addition, the cab's large space and low noise processing also enhance the user experience in different aspects. The structure with high safety, high durability and high wear resistance not only excels in the crushing work, but also performs well under special working conditions such as mines.

The STL water-jacketed gold concentrator is a kind of gravity separation equipment. It was developed by Changchun Gold Research Institute Co., Ltd. in 1985 and entered the market. At present, it has been used in many domestic and foreign companies. It is suitable for the recovery of single gold in placer gold, vein gold mines and polymetallic mines, instead of mercury plate operations. The addition of large single gold particles in the collected ore before flotation can further increase the recovery rate of gold mines, and it can also be used from gold-bearing mines. Separate single gold from flotation gold-copper concentrate and flotation gold concentrate.
The main indicators of this series of equipment basically reach the level of similar international products (such as Nielsen gold selectors, etc.). Compared with similar equipment at home and abroad, this series of equipment has the advantages of high cost performance, easy operation, and low maintenance costs.
