The knowledge about EPC companies and mining equipment

Many people always hear about EPC. However, does everyone know well it?
EPC means engineering, procurement and construction. EPC companies show the contract model. In other words, EPC is a kind of contract model not an enterprise. Basically, designing institutes carry out EPC contract in the domestic. Sometimes construction units do EPC contract. So if you have a clear knowing about EPC? Then let us come to the next topic-mining equipment.
Compared with the common belt conveyor, pipe conveyor has the following advantages.
(1) The pipe conveyor adopts the sealing conveying, which could leave out the cost of building gallery of common belt conveyor. At the same time, it could prevent materials from rainwater and wind blow. And the harm to environment could be avoided.
(2) The pipe line could bend in horizontal plane or vertical plane, the max angle of bending reaching 90 degrees in horizontal plane. The minimum bend radius is 300 times as long as pipe diameter.
(3) It could be designed to large inclination conveyor, the max inclination reaching 30°.
(4) The pipe conveyor could leave out related mechanism of transfer point applied in common belt conveyor, reducing the investment of equipment.
(5) Return stroke could be designed to convey materials.
(6) It is particularly suitable for long distance, steep and rough terrain, swerving terrain. The economical efficiency and practicability are its obvious features. It is widely used in the power plant, port, mining and other complicated topography areas.
(7) It is particularly suitable for conveying the materials that pollute the environment, such as coal, cement, coal ash and etc.
About stacker reclaimer, the introduction is as follows:
The stacking and reclaiming could be realized through central control room and on-machine control room under the automatic control of stacker reclaimer. When needing central control room to control the automatic operation, operating personnel press the button of automatic operation and then start button. The electric equipment of stacker reclaimer would start according to the predetermined procedure. The overall unit operation enters into normal automatic operation. On the platform of central control room, users could start or stop the complete machine system of stacker reclaimer just through pressing button. The set of equipment adopts three operating modes: automatic control, manual control, on-site control(maintenance). Each control mode is realized through change-over switch.
I am so happy sharing some knowledge with people in the world. At the same time, if my readers have new knowledge about mining equipment, please kindly let me know~

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
