XY series high-efficiency composite fine crusher
The high-efficiency composite fine crusher is a new type of pre grinding equipment independently developed by our engineering and technical personnel
Product details
The high-efficiency composite fine crusher is a new type of pre grinding equipment independently developed by our engineering and technical personnel after years of research and practice. It has the advantages of high efficiency, detailed crushing effect, wear-resistant materials, and energy saving, and is widely used in fields such as refractory materials in cement mines. The pre crushing effect for cement clinker is more ideal. The unique structure and composite roller pressing make it at the advanced level in China.
Obvious advantages:
1.The crushing effect reaches and approaches the level of imported roller presses.
2.The price is 10% to 20% of the roller press (very cheap).
3.Each ton of clinker only consumes about 0.3 RMB (exceeding the international advanced level).
4.The failure rate and maintenance volume are reduced by about 80% compared to roller presses (no professional technicians are required for use and maintenance, this machine is a foolproof model).
5.The power consumption is only about 10% to 20% of that of a roller press.
6. 3—4Recovering all equipment investment in about a month.

1、 Project Background:
Cement is the fundamental raw material of the national economy. Since the reform and opening up, China's cement industry has developed rapidly, with significantly improved overall quality and production ranking first in the world for many years. In order to save energy and reduce pollution, the cement industry is gradually moving towards scale, with daily production increasing2500The production lines with a capacity of over 10000 tons have been increasing year by year, and even production lines with a daily output of 10000 tons have gradually been built. The cement industry is a high energy consuming industry, and how to adopt advanced processes and equipment to reduce energy consumption and increase production is the most concerned issue for cement enterprises. The key process to reduce energy consumption lies in the pre crushing of clinker before grinding.
At present, pre crushing before grinding both domestically and internationally mainly uses roller presses, hammer presses, or jaw presses, as well as counterattack presses. The disadvantages of roller presses are mainly manifested in the following aspects:
Firstly, the energy consumption is high. Although the particle size of the grinding machine is greatly reduced and the energy consumption of the grinder is reduced, the roller press itself has a high power consumption;
Secondly, the overall price is expensive;
Thirdly, complex maintenance and delayed production;
Fourthly, maintenance costs are high.
The disadvantages of hammering or scratching are:
Firstly, the discharge particle size is too large to meet the requirement of reducing the energy consumption of the mill;
Secondly, the hammer head is prone to wear and tear, resulting in high replacement costs. Although counterattack breaking has some advantages over hammer breaking, the particle size of the discharged material is still large, and the effect of reducing consumption and increasing production is not significant.
2、 Project Introduction:
After years of practice, our factory has independently developed and researchedXYSeries composite clinker fine crusher，Adopting a composite form of no hammer breaking and roller pressing, the main engine is divided into three parts, with the upper part being the feeding and air circulation assembly, with a novel and unique structure. There is a stacking pool in the feeding section to prevent the wear of the feeding drum during stacking. The vortex type internal circulation air creates negative pressure at the feeding port to prevent dust. The middle part is first level broken. The high kinetic energy impeller throws the material onto the counterattack plate, causing it to collide and break into pieces, forming a material flow that causes the materials to collide and rub against each other until they are finely crushed. There is a screening system inside the crushing chamber, and fine powder flows into the discharge port through the sieve plate under the action of wind. The lower part is the rolling zone, where the coarse and fine materials have been separated through a first level of fine crushing. After the fine materials are removed The coarse material flows into the roller pressing chamber, and under the action of the driving roller, it is squeezed and crushed for secondary crushing. The final material is discharged through the discharge chute. The internal circulation composite crushing structure ensures the fine particle size of the material. High energy impeller throwing replaces hammer type cutting and crushing, thus saving wear-resistant materials.
This unique composite structure has the following advantages:
1Power saving
1）Adopting a hammer free crushing and rolling method.
2）Composite crushing. Avoiding large chunks of cement clinker from directly entering the roller press, the roller press consumes less electricity and has a significant energy-saving effect.
2Long service life of grinding body
1）The use of hammer free impact crushing greatly reduces the consumption of grinding materials.
2）The key parts of the small lining plate are embedded with hard alloy, which extends the service life.
3）Diameter of clinker entering the powder mill95%The above is less than5mmReduce the consumption of wear-resistant materials in the powder mill60%The above.
3Low fault
The diameter of the clinker entering the roller press after being crushed in a hammer free form95%The above is less than12mmAnd there are50-60%less than5mmThe material has been diverted by the powder selection device inside the machine and no longer enters the roller press, so the failure rate is very low.
4The powder mill increases production in30%~50%左右
1）After being processed by a fine crusher, it enters a powder mill with a diameter smaller than5mmThe material is95%Left and right, significant energy saving and consumption reduction.
2）Each ton of cement grinding processing cost can save6~10About yuan.

Lei Qianzhi, President of the China Cement Association, has visited our factory several times and inscribed: "Adhere to independent innovation and create high-quality domestic products
With the development of China's economy, a conservation oriented society and sustainable development have become a consensus among the people. As one of the pillar industries of the national economy, the development of the cement industry will inevitably enter the path of energy conservation and consumption reduction. According to professional statistics from the China Cement Association,2008The cement industry will take energy conservation and consumption reduction to a higher level in the coming year, and the pre crushing market will also reach a new level.
