5) Breaker maintenance. When breaker engine off, must inspect the tie bolt whether reliable and easy to wear the part attrition degree, whether needs to replace. To pin roll breaker, but also should remove the tooth interdentally the lumber. Inspects the breaker protector, causes it maintenance good condition.

Except line service outside, but also should carries on the preventive maintenance to the breaker and the appurtenance like lubrication cooling system, for example the minor repair, repairs, the overhaul and so on.

Besides above five, to breaker installment, both must guarantee reliable, the position is correct, and must pay attention to the ant vibration request, and transfers to the adjustable spot the appropriate position. This to lengthen the breaker the life is very important!

6 Smashing technology development tendency

1) The equipment is large scale day by day, simplifies the equipment and the technical process. The steel ball grinding machine diameter has reached above 5.5 , the electric power reaches above 7000 , when Taiwan output above 300 .The cement industry use biggest tube mill is , the electrical machinery power reaches 8700 .Vertical rubs in the series the grinding pan diameter to reach above 5 , electrical machinery power above 5000 , when Taiwan output above 500 .

2) Uses pre-drying (or pre-stave) form composition drying (stave) the powder rubs the integral unit.

3) The grinding machine and the new highly effective splitter and the conveyor matches, composes each kind of new dry process close up powder to rub the system, enhances the powder to rub the efficiency, the increase powder rubs the merit the effective use.

4) Uses the electronic quota to feed the stock weighed -  fluorescence analyzer - electronic accounting machine regulator system, the control raw material ingredient, for enters the kiln crude material ingredient evenly to create the condition stably. The grinding machine system operation automation, the application automation adjustment return route and the electronic accounting machine control production, replaces the worker to operate, endeavor stabilization of production.

Presently, the powder rubs the equipment the development, mainly also in the energy conservation aspect, makes every effort to reduce the powder to rub the electricity to consume. At the same time, also is taking the positive measure to reduce the attrition as far as possible abrasion. In recent years, overseas to the superfine smashing and the graduation equipment, the craft, the tiny pellet granularity measured the grade aspect the research is extremely active, this is because compound materials, new ceramics, electronic material and so on many most advanced technique rapid development decisions. In the advanced industrialized country, the micron level superfine smashing equipment transited its invention time, but enters mature, necessary, the perfect stage; the equipment research is facing the submicron level superfine smashing and the micron level precise graduation direction develops. The smashing technology development mainly displays in the product micro refinement, the fine powder fictionalization, the equipment automation, conserves energy the new craft and the equipment and lowly pollutes high strength material aspects and so on application.

辊式破碎机、冲击式破碎机和锤式破碎机的发展概况

辊式破碎机、冲击式破碎机和锤式破碎机的应用范围非常广泛，能对各种不同硬度的、粘度和湿度都较大的物料进行粗碎、中碎和细碎。特别值得指出的是这几种破碎机的破碎效率高，能耗小。目前的辊式破碎机、冲击式破碎机和锤式破碎机在设计、制造和应用上都取得了一些新的进展。

英国Babbitless(GB)公司制造了一种破碎比高、能耗低的Dragon冲击式破碎机。该机的系列产品有：PS10.05(转子为1   0.5 )，PS10.10(1  1 )，PS12.13(1.2  1.3 )三种规格。
