Analysis of the reasons for the unqualified discharge of mobile crushing station

For mobile crusher production process, whether it's fault, or the analysis of the causes of the decline in output, or is to solve the unreasonable phenomenon of discharge, is important in the production operation, the operation is to ensure that the production of benefit, analyzing the causes of substandard different phenomenon is caused by different reasons, here is to introduce the discharging substandard phenomenon is what causes problems.
1. The crushing ratio
Broken ratio refers to the imported raw materials and finished products after crushing particle size ratio, the greater the ratio, the more broken than, and vice versa, for the production process of crusher, broken than large needle flake content is increased, so the production, for the broken ratio adjustment is one of the important measures to guarantee the material, of course also not broken ratio is too small, which can cause the system output reduction, increase in circulation, make the crusher wear increases, so broken than need to choose appropriate;
2. Feed size
For crusher, different type or different types can be processed into the material size is different, if the feed particle size does not fit, can also cause discharge phenomenon of substandard quality, such as when the feed particle size reduced from 100 mm to 50 mm, the needle flake content in finished product fell by 38%, so feed particle size must conform to the requirements of production equipment;
3. Mobile crusher cycle load
The working process of the breaker is in a closed cycle, large discharge, increase the load cycle, stone will get better grain shape, in the whole process, due to the cyclic load increase, the wear and tear of equipment of the system increased, but when the discharging mouth up, Lord of the broken motor load can be reduced, finished product grain deformation is good, so in production, is very important for cycle load adjustment;
4. Open and closed loop
In the production of crusher, circular separate road cycle and closed-circuit circulation, the former is called screen before they are broken, the latter is called the first crushing after screen, screen before breaking refers to after primary crushing of the material after finished sieve sieve first, then enter the secondary crushing inlet are broken, so the output of finished product increases, the needle flake content also increased, broken after the first sieve is refers to the primary broken all into the secondary crusher inlet, to break into the finished product after screen for screening, the whole system is a closed system, no broken material loss, grain shape is good, but the product in the actual production of the crusher,The movable crusher can choose open circuit or closed circuit according to the requirements of production;
Crusher are mainly introduced above discharging substandard cause analysis, the analysis of the problem mainly from four aspects, the distribution is broken ratio, feed particle size and cycle load and the open and closed cycle, the above detailed analysis of the impact of these aspects for discharging, in the actual production, according to the requirement of the production should be appropriate choice of every aspect of the factors.
