Product Description

The main equipments of cement production line including: rotary kiln,cyclone preheater,cooling machine,crusher, vertical mill, roller press, cement mill, coal mill, dryer, dust collector, packaging machines, bulk machines, conveyors, electrical control etc.

Pre-homogenization:
Crushing: during the process of cement production, most of the raw materials need to be crushed, such as lime stone,clay,iron ore,coal etc. Limestone is the largest amount raw material for cement production, the particle size is bigger and the hardness is higher, so the limestone crushing have an important position at the material crushing of cement plant.
Raw material pre-homogenization: the pre-homogenization technology is achieving the raw material initial homogenized by scientific stacker and reclaimer technology during the storage and reclaimer process of raw materials, to ensure the raw material ground has the capability of storage and homogenize.
Raw materials homogenization: At the process of dry process cement production, stabilize the raw material ingredient is the premise of clinker sintering, and raw materials homogenize system is used for stabilize raw material ingredient inlet the kiln.
Preheating and decomposition: We use the preheater to finish the preheat and decomposition of cement raw materials, replace part of the capabilities of rotary kiln and reduce the length of rotary kiln. The materials finished gas exchanging heat process inside rotary kiln under the state of suspends and preheat. The raw materials and fervor gas exhausted from rotary kiln are intensive mixed, enlarges contact area of gas, heat transfer speed higher, heat exchange rate higher, production rate higher, and heat consumption of clinker sintering lower.
The material dispersion: 80% raw materials fed into the preheater pipe will exchange heat at the entrance of pipe. At the impact of high speed updraft, materials turn up with air flow, meanwhile dispersed.
The right of gas-solid separation: when the airflow with material powder get into cyclone, and were forced to do rotate flowing at the annulus space between cyclone barrel and inside barrel while doing downward movement.
Precalcining: The precalciner technology is a technological leap of cement calcination process. It is added between the preheater and calciner kiln using kiln tail rise flue, set the fuel injected device, so that the process of carbonate endothermic exothermic decomposition of the fuel combustion process and raw materials, in the decomposition furnace to the suspended or fluidized state quickly, so that the decomposition rate of kiln feed is increased to 90%. The original task decomposition of carbonate in the rotary kiln, and moved to the decomposition furnace; fuel from the calciner to join the majority, joined by a small part of the kiln, reducing the heat load of the kiln firing zone, extending the liner material life, in favor of large-scale production; due to the mixing of fuel and raw materials, timely delivery of fuel combustion heat to the material, combustion, heat transfer and carbonate decomposition process can be optimized. So it has a series of excellent performance and features of high-quality, high efficiency, low power consumption.
Sintering: After preheat and predecomposition completion of raw material in the cyclone preheater, next process carried out is clinker firing in the kiln. The carbonate rapidly resolved and occur a series of solid-phase reaction in rotary kiln to bring the mineral into being. As the material temperature close, the liquid will become minerals dissolved in the liquid phase reaction and generates a large number (clinker). After the clinker burning, the temperature began to decrease. Finally, the cement clinker cooler unloading the kiln clinker cooler temperatures to the downstream transport, storage libraries and cement mill can withstand temperatures of hot clinker while recovering sensible heat, improving system thermal efficiency and clinker quality.
