We can see that it is the most economical and thorough way to process waste by cement rotary kilns. What's more, because the new type of dry process cement production line has replaced the vertical kiln cement production line, it has provided better opportunity for this method. In addition, America and Europe refer to waste as the secondary fuel. It is because the flammable waste can replace some fuels to decrease the fuel demand in cement industry, which saves the primary fuel and decreases the discharging of some waste air like CO2.
As far as its replacement function concerned, using rotary kilns to burn waste is a comprehensive project to protect environment and resource.

The whole production process of cement can be summarized as 'two grinding one burn', the' burn' refers to that the raw materials after ground and well confected will be firing to clinker under high temperature of the rotary kiln. Henan hongxing will tell the details of the feeding procedure of cement rotary kiln:
Tell the site inspector stop the kiln slow rotating and separate the kiln from slow turning clutch, set the kiln at a speed of 0.4 ~ 0.5rpm and then start the kiln motor;The Rotary kiln as one of the main drying equipment, its usage is very wide: building material, metallurgy, chemical, environmental protection and many other production industry。 It is also widely used for turning round of solid materials machinery, physical or chemical processing。 The rotary kiln can be used to burn the cement forging outside, it can still be used to forge the clay, limestone and slag drying, etc。

 Barite can be used as a white pigment ( commonly known as Lithopone), also can be used in chemical industry, paper making, textile packing, and in glass production in it can serve as a flux, to increase the brightness of glass. However, its most important role is used as aggravating agent used in drilling industry and barium refining.
To heal broken fracture, doctors usually use stainless steel nut, bolt, splint and borer to fix up the broken bones. This must be process two operations, first to implant these stainless steel materials, and then take them out. Dutch scientists have invested a kind of plastic, which can be self decompose and become carbon dioxide and water after implant into the human body for two years. Extended quartz also includes high-temperature quartz (b-quartz). Quartz, also called silica, mainly is the raw material of quartz sand (also called silica sand) production, also quartz refractory material and fire ferrosilicon materials. In addition, "quartz" is a common person name.

According to the characteristics and the status of China's iron and steel and mining enterprises, small and medium-sized chain grate machine - rotary kiln production line teams get rapid development because it's advanced and practical in techque, low in investment and it can be built in a very short time and quickly put into production and the benefits are good.
Rotary kiln pelletizing technology is a kind of pellet process which makes use of chain grate machine dry and preheat raw pellet, rotary kiln consolidates and burns pellet in rotary kiln and uses annular cooling machine to cool finished pellet. Pallet produced by this technology is a high-quality blast furnace feed. It has such commercialization advantages as high-grade iron content, good metallurgy capability and being suitable for longtime storage and long-distance transportation. And if used together with sinter, it can effectively decrease coke rate and promote furnace productivity. Its process is advanced and the secondary energy utilization is full and it is environmentally clean. The pallet quality is high and energy consumption is low, and it has good economic and environmental benefits. While the shaft furnace palletizing technology is difficult to be used for large-scale production, because of the the non-uniforminity of pellet quality and poor adaptability to raw materials.

Wet and Dry Magnetic Separator Process Differently
The Magnetic Separator can separate raw materials with different magnetic rigidities. The machine works under the magnetic force and machine force.

The Rotary kiln under the action of raw materials in the friction with the wall together rises slowly, when it was turned to a certain height。 The horizon of raw material surface layer is equal to the viewpoint of the formation of the accumulation of raw material, the raw materials particles falls because of gravity, it slides along the material layer。 Because the rotary kiln have certain gradient, and raw materials particles rolling, the biggest direction along the slope down, so it moves forward a certain distance。 When raw materials in the stove move, the raw material of particle movement way is cyclical change, or buried in material layer inside and kiln movement together, or to the material on the surface layer and came down。 But only in the raw material along the surface layer of particles landing in the process, it can grow along the kiln direction。
Rotary kiln generally falls into the cylinder body lie place, which can be turned movable are called the rotary kiln; Another type of kiln cylinder which is made not for rotating is called shaft kiln.

Rotary kiln is usually known as rotatory dryer,handling by carrying it into direct contact with a heated gas. The dryer is made from a huge, rotating cylindrical tube.

Capabilities of rotary kiln

Since the 16th century, United Kingdom applied the first set of fixed screen to the coal industry, many kinds of screening equipment has appeared in the world, such as cylinder screen, shaking screen, roller screen, resonance vibration sieve, etc. And the vibrating screen possesses absolute advantage in all screening equipment with its simple structure, large capacity, work reliably, its footprint is about 95%. After the 1970s, with the advancement of screening technology, the emergence of new screening machines revolved around the development of vibrating screen, such as enhanced vibration parameters, equipment of large scale, machine parts and components of three, popularization and application of self-synchronous technology, etc. While others such as roller screen, drum sieve, shake the screen gradually being phased out.

Screening is a separation process carried out according to the material particle size, which means the process separating the smaller particle size from the larger particle size with screen. The handling and processing of materials often need screening operation, so its use range is very wide, including mining, metallurgy, foundry, chemicals, fertilizers, seeds, powder, food, medicine, feed, paper and other industrial sectors. Although these areas all need screening operations, the material nature and process conditions are different from each other, as well as the various requirements for screening equipment. So, we only provide the information on screening equipment for mine.

Cone crusher is an ideal crushing equipment used in many fields. It is widely applied in metallurgical, construction, road building, chemical and phosphatic industry Genuine spare parts. Cone crusher is suitable for hard and mid-hard rocks and ores, such as iron ores, copper ores, limestone, quartz, granite, gritstone, etc.
Grid Plates (also known as locator plates, tooling plates)--customizable grid patterned locator system. Red Star grid plate is manufactured with advanced techniques and excellent wear resistance materials. Our company offers various grid plates according to the certain requirements of our customers.

A spring cone crusher is used for rocks of medium-to-hard hardness levels, and has a variable-sized crushing chamber. A sand-maker crushing rocks, including metal ores, into extremely fine aggregates, while a drying hammer crusher is a floor-to-ceiling machine that specializes in soft or moist raw materials. Finally, a ring hammer crusher specializes in both moist and dry aggregates, and pounds them down to size with a series of hammers. Aggregate crushing is a long, laborious process, involving a number of stages and several pieces of heavy machinery. Regardless, crushed aggregate is a necessary component of almost any construction project.
Mobile crusher is mainly used for metallurgy, chemical industry, building materials, water and electricity often required removal of materials processing operations, especially for highways, railways, water works and so on. Mobile crusher can be divided into tire type mobile crusher and crawler type mobile crusher. Red Star can offer you many types mobile crusher:jaw mobile crusher, cone mobile crusher, impact mobile crusher, multi-crushing mobile crusher and crawler type mobile crusher etc.If you have the cone crusher with high energy, it is no longer the difficult problem in the processing of steel slag.
