EPC means that one turnkey company is responsible for prospecting, designing, purchasing, constructing, commissioning, and other process. The working content, responsibility, tasks will be  explicitly stipulated in contract form. Internationally, project general contracting in petroleum, chemical, electric power and other industries is called as EPC. Most EPC companies would choose large project to earn money such as contracting the construction of stacker reclaimer. Sometimes, EPC companies would serve for materials handling industry such as the design and manufacturing of pipe conveyor. According to the practice at home and abroad, mature EPC companies should have following features. 
The operating income mainly comes from providing project services(including project contracting and project management) to the end user. 
The business range covers the total process of project including preliminary consultation, design, purchasing, construction, commission, EPC, PMC, PM and other services. 
The mature EPC companies have comprehensive abilities including design, purchasing, construction. Besides, they have advantages in some aspects.
The project general contracting has various types including EPC, EPCm, EPCs, EPCa, LSTK, BOT and etc.
The project control department, quality control department, designing department, purchasing department, construction department, commission department and other departments would be established to meet the developing requirements. 
There are many professionals in various fields such as language, computer, technology and etc. There are mature project managing system including institutional framework responsibility, project management procedure documents, work book of job position.

The Comparison of Portal Scraper Reclaimer and Boom Scraper Reclaimer

图片
The portal scraper reclaimer and boom scraper reclaimer are the main types. The differences are as follows: 1. The portal reclaimer has reasonable structure. The partial weight of portal frame and scrapper reclaimer is supported by the wall(blocking materials). In this way, the stress state under the central cylinder, and the running of the portal scraper could operate smoothly. And the boom scraper reclaimer's load could be transmitted to the central cylinder. In this way, the design and manufacturing difficulty is large and the stability of the equipment is bad. 2. The portal reclaimer has compact structure, and there is no need to design the balance weight. The space occupied under the portal reclaimer is small. The boom reclaimer should be designed with large balance weight. 3. The portal reclaimer need the circle track in the wall(blocking materials), and the related cost of setting circle track. The balance weight load of the boom scraper reclaimer is central under t

The Analysis Of Advantages And Disadvantages On Boom And Portal Bucket Wheel Stacker Reclaimer

图片
As we all know, the stacker reclaimer coordinates with belt conveyor to complete the handling process of materials in most conditions. The bucket wheel stacker reclaimer, as one of the mining equipment , is mainly used in handling materials. According to the structure form, there are boom bucket wheel stacker reclaimer and portal bucket wheel stacker reclaimer. The boom bucket wheel stacker reclaimer is widely used in port, coal storage yard, earthwork, coking plant, cement plant and etc for handling coals, ores, and other materials. The portal bucket wheel stacker reclaimer is mainly used in power plant. The boom bucket wheel stacker reclaimer handles materials through the rotation. So it is necessary to set the large rotating bearing, which increases the cost. The portal bucket wheel stacker reclaimer handles materials along the straight line without the large rotating bearing, which could save the cost. The boom bucket wheel stacker reclaimer could handle materials over 90 d

The Features Of Different Apron Feeder

图片
In general, the apron feeder could be divided into three types including heavy, medium, light type, which is the continuous transportation machinery widely used in mining, metallurgy, construction materials, ports, coal and industrial and mining enterprises. The apron feeder is mainly used as the storage bunker to continuously supply the materials or transfer large material to crushing machine or batching apparatus. The apron feeder is one of necessary machine for handling materials in the process of continuous production. Sometimes some EPC companies would choose stacker reclaimer, belt conveyor, stone crusher and etc to complete the transportation of materials. The light apron feeder is suitable for transporting materials under 160mm granularity in short distance. It is used for continuous feeding in mine, mill plant, chemical industry, cement, building materials. The light apron feeder could be installed horizontally or obliquely. The maximum inclination degree is 20, which is su
