The life circle of one project could be divided into concept, developing, implementing, controlling and ending processes. During the concept process, the main items include cost analysis, and study of project feasibility. The purpose is to make a report and receive the approval and support. In the real work, most people just have an idea or a concept and then quickly turn to the developing process. However, during the developing process, the project planning paper, budgetary cost and job plan should be prepared for carrying out the work.  Most people carry on work with a general schedule of project and then finished the job. In the implementation phase, people should have a job plan and the fixed cost estimation. In fact, most people just regarded the stage as a project. Then at the end of the project, people would lose control because of no specific "milestone". So during this time, people would discuss the lessons of each project. But for the done work, people could not

The number of mining manufacturers is increasing year by year in recent years, resulting in the violent competitive situation. Many experts predict that the mining equipment will develop in the following directions.  Environment protection: The principle of low consumption and light weight is adopted by many designers. In the course of production, some harmful materials would be avoided. Some parts could be recycled as fuels. Large scale machines: For example, the volume of ball mill is 5-8 times larger than that last ten years and the volume of autogenous mill is 15-20 times larger than before. At present, there is a lot purchasing information for large-scale mining equipment, showing the demand situation of the market. Automation: The instrumentation and sensor for monitoring feeding capacity, pulp density or other measure parameters have been prepared basically. The difficulty is grade detection of various materials. Optimization design: The advanced technology should be

The advantages of EPC model are as follows: 1. EPC contractor is responsible for the implementation process of project. This could helps the planning and collaborative operation of the overall project. And many problems could be solved. For example, the connection problem between design and construction could be solved effectively, reducing the intermediate link between purchasing and construction. In this way, the contradiction among practicability, technicality, security could be solved also. 2. The limit between working range and responsibility is clear. And the responsibility and risk during the construction period could be transferred to the general contractor. 3. The total prices and duration of the contract are fixed. This could help the control of expense and progress. 4. The advantages of project management could be showed, realizing the various objectives of project management. 5. The owner could be free from the specific affairs and the pay attention to the import

Belt conveyor is a kind of equipment transporting materials through the friction drive. Different belt conveyor design could created different types of belt conveyor. Our company mainly has the following types about belt conveyor. Downwards transportation belt conveyor, plane turning belt conveyor, coal mine belt conveyor, pipe belt conveyor( pipe conveyor ) and other conveyor components are the main products of our company. Among them, the pipe conveyor is widely used in the metallurgy, construction materials, chemical industry, thermal power, ports and etc. It is mainly applied to convey ores, coals, raw materials, waste residue, and rubbish. The materials is conveyed in the pipe, which means the materials are conveyed in the closed environment. So the materials would not scatter everywhere. At the same time, the materials will not be polluted by the outer things. The change of weather will not influence the conveying of materials, realizing pollution-free conveying and red

A s one of the EPC companies , has the strict requirements in designing. Because the most mining equipment belongs to the non-standard products, this is a big challenge  to the designers. The designers should design related products according to many factors. Our company has an advanced belt conveyor. Especially for the screw conveyor, the designing level of JULI is higher than other companies. The belt conveyor, as one of mining equipment, is the non-standard product. The belt conveyor could be designed according to the operating environment and conveying lines. The key points of belt conveyor design are as follows: 1 The working environment and operating conditions The designer should consider the operating duration, working frequency , the service life of belt conveyor, and methods of loading and unloading. For the working environment, the designer should consider the environment temperature, the environmental requirements, and the flexibility . 2 The conveying lines and

Crusher Load The crushers and ball mills applied in mining and construction use the converter to get the high efficiency. Large scale kiln load Ring kilns applied in metallurgy, construction and other major industries usually adopt direct current and commutator machine to adjust the speed. Because of the low efficiency, recently many enterprises use the converter to control the machine and get the good production. Stacker reclaimer load The stacker reclaimer is the main equipment in the coal yard, port, mining. The main function is stacking and reclaiming materials. The realization of self-motion stacking and semi-automatic reclaiming increases the equipment reliability. The equipment runs stably and it is without the impact and shaking. The relaiming process is with the rotation adjustment of 1/cosφ, increasing the efficiency of rotating reclaiming and the evenness of conveying coals. Many EPC companies would choose the converter, especially for the mining industry(i

Many users of mining equipment want to increase the efficiency of belt conveyor. The basic solution is good belt conveyor design. For example, we talk about the turning belt conveyor here. Turning belt conveyor is widely used by several industries because of its special function. The design principle of turning belt conveyor is different than the normal belt conveyor. The design thinking and principle are more complicated. Belt conveyor is mainly applied in the mining, chemical, metallurgy and other industries. In most situations, the belt conveyor is not set in the linear type, but in the conditions of certain curving. The middle of the belt conveyor may involve in mutual matching of various equipment. So we should consider the site layout of belt conveyor to complete the belt conveyor design, reaching the requirements of users. This kind of belt conveyor has the obvious advantage, that is high efficiency. For the most EPC companies, they prefer designing the turning belt c
