Uzbekistan customer officially signed a cement production line of 1000TPD with CHAENG

Due to the central Asian region is under the influence of "One Belt and One Road" policy, they started to develop the infrastructure construction, will undoubtedly increase the demand for cement. After a multinational investigation contrast, Uzbekistan customer officially signed a cement production line of 1000TPD with CHAENG (Xinxiang Great Wall Machinery) on March 16, 2016.

This cooperation only lasted for less than 10 days from investigation to sign the contract. It’s the technical strength and good reputation in the industry of CHAENG to let customer to make a firm choice. It marks that CHAENG achieves new breakthrough on exploiting central Asia market again.

Project Advantages

For the new type cement production line, Chaeng adopts the advanced energy saving technology in the crushing and calcining process, the waste hot air generated from the rotary kiln can be recycled for raw material drying and pre-heat pyrolysing to achieve the energy saving , environmental friendly purpose.

Powerful crushing,scientific stockpiling

The limestone crushing use single-section hammer crusher that feeding size is 800mm, production capacity is 180 t/h, and grinding by advanced vertical raw mill- GRMR22.31. Scientific material piling and taking technology, to achieve the initial raw material homogenization.

New vertical mill grinding process, Low energy consumption in grinding

The energy consumption in cement grinding process accounts for more than 60% of the whole production line, therefore, it has great significance in ensuring product quality and reducing energy consumption by using high efficiency and energy saving GRM series vertical roller mill to deal with raw material, coal, clinker.

Preheating before calcination , High efficiency and energy saving

Raw materials are sent into φ3.2x50m rotary kiln to be calcined after preheating and precalcining in the cyclone preheater . That is conducive to improve the production efficiency of kiln system, shorten rotary kiln length, and reduce the heat consumption of clinker calcining.

Low Investment ,Environment Friendly

Vertical mill grinding system operate in negative pressure, low dust pollution; System equipment layout is compact, low area occupying, low investment in civil construction; Environmental protection in recycling kiln exhaust gas.

Study on grinding process

It has been the consensus that vertical mill has advantages in the cement production, especially in the clinker grinding stage from the survey. Vertical mill has the feature of low electricity consumption, high production capacity, high cement quality, thus, it is the trend that vertical mill replace the ball mill.

Since the first ball mill produced in 1968, the company has produced more than 2600 sets of mills and rotary kilns in various specifications, and the products are sold to each provinces of China, and exported to America, Russia, Japan, Brazil, India, South Korea, Vietnam, Kenya, Iran and others, enjoys high market reputation.
