This blog mainly introduces Belt conveyor and Pipe conveyor . Hope my readers could get some help from this blog.
The mining equipment could be used on the conditions of mining product marking attached. There are various mining equipment. About underground mines, there are elevating conveyor, water pump, fan, air compressor, scraper and other devices. About open-pit mines, there are drilling machine, mine-car and other equipment. Besides, there are crusher, belt conveyor, loader, excavator, ball mill, magnetic separator, classifier and other equipment. Tractive effort the belt conveyor design needs is transferred through rubbing action between driving pulley of driving device and conveyor belt. So the friction drive forms. To ensure the transmitting of acting force and traction components' no slipping on the driving wheel, the following conditions must be met. (1) The traction components should have enough tension. (2) There should be certain roughness on the contact surface of traction belt and driving pulley. (3) Traction belt should have an enough surrounding angle on the driving wheel. Pipe conveyor is a new conveyor transporting bulk materials in the state of sealing, which realizes environmental protection conveying. Pipe conveyor is suitable for complex topography, and could convey materials deviously in the three-dimensional space. Pipe conveyor could simultaneously and bilaterally convey different materials in upstream and downstream channels. The large conveying angle reduces the length of the equipment, land area and costs. For those advantages, the pipe conveyor has a bright market prospect. 处进行编辑.

Screw blade uses the design of variable pitch screw, which makes materials filling rate change from 100% to below 70%. At the same time, screw conveyor can stay the uniform acceleration motion of conveying materials, reduce the delivery resistance and prevent material from plugging and blocking. The heavy duty apron feeder is the auxiliary equipment of transportation machinery. The heavy duty apron feeder is regarded as the hopper to continuously and steadily feeding materials to primary breaker in the departments of cement, building materials and etc. Besides, it could be used to convey materials with large particle sizes and specific gravity. The heavy duty apron feeder could be installed horizontally or obliquely, with the max upward inclination of 12 degrees. To avoid the situation that materials directly hit the feeder, it is required that emptying of hopper be forbidden. Various apron feeders could be divided into right driving and left driving according to the driving modes. From the moving direction of materials, if the driving system is on the right of the equipment, this is the right driving. On the contrary, it is the left driving. 编辑. Bucket wheel reclaimer mainly consists of bucket wheel gear, hanging stick and top metal structure, boom belt conveyor(The belt conveyor design adopts the theories of high productivity, conveying capacity, low energy consumption, continuous long distance transport, stable running, low noise, low pollution, simple structure and low cost),lift and tilt mechanism, slewing mechanism, revolving platform, running mechanism, door seat frame, handler's cab, control room, trailer and other devices.
Boom bucket wheel stacker reclaimer takes out materials in rectangular stockyard through rotating bucket wheel device and three motions of running, pitching and slewing to boom mounted belt conveyor. And then the materials are unloaded as required to belt conveyor on the ground through the center system of hopper system. 处进行编辑. This blog mainly introduces some conveyors and the advantages of FIDIC clause. Hope my readers could get some help from this blog.
The first one to be introduced is belt conveyor. The belt conveyor is widely used for conveying bulk materials in metallurgy, mine, coal, ports, power plants, and building material industry. For the belt conveyor design principle, it adopts the theories of high productivity, conveying capacity, low energy consumption, continuous long distance transport, stable running, low noise, low pollution, simple structure and low cost. The second one to be introduced is screw conveyor. Screw conveyor has following characteristics: Screw blade uses the design of variable pitch screw, which makes materials filling rate change from 100% to below 70%. At the same time, screw conveyor can stay the uniform acceleration motion of conveying materials, reduce the delivery resistance and prevent material from plugging and blocking. Finally, let us come to know the advantages of FIDIC clause. There are many advantages, if adopting FIDIC clause to manage, execute and sign contracts. 1) Coherent and logical statement is one of the advantages. The risk sharing between EPC companies and clients is fair and reasonable. There are no ambiguous words, so any party cannot find the weakness to take advantage of. 2) The definite provisions on rights and obligations of EPC companies and clients, engineer's duties make a clear boundary that both parties have their own rights and obligations while the engineers have clear duties and privileges. In this way, many disputes and claim events can be avoided and both parties are restrained in the course of contract execution. 3) FIDIC clause is adopted by many countries and is familiar to most contractors in the world. At the same time, it is recommended by the World Bank and other financing institutions, which is beneficial to realize the international comparative bidding. 4) Using FIDIC clause is easy to manage contracts. It has better results for ensuring engineering quality and controlling project cost and schedule. This blog just briefly introduces some mining machines. If you have interest, please continue to read my articles. I will renew contents in next blog. Welcome to read them. 行编辑. Blending stacker reclaimer applied in the circular stockyard, one of mining equipment, is mainly used for stacking and reclaiming raw coals. It is applied in raw coal preblending stockyard in the cement production line. Blending stacker reclaimer has functions of realizing pilingherringbone and full-section reclaiming, which could finish simultaneously or respectively stacking and reclaiming operations.
The Pipe Conveyor is a special equipment on the base of troughed belt conveyor. Featuring closed conveying, this conveyor can avoid material leaking and splashing, dust cloud, foreign material mixing, as well as incursion of rain or snow. The coupler is one of conveyor components. The operating principle of fluid coupling is as follows: A certain amount of working liquid is injected into the working chamber of coupler. The pump impeller gets mechanical energy and then convert it to hydraulic energy. The hydraulic energy drives turbine to rotate, during which hydraulic energy changes into mechanical energy and the energy is output through output shaft. The machine is driven by constantly changing energy, realizing the energy transfer from prime mover to working machine back and forth. 行编辑. |
