What factors will affect the normal operation of the feeder
First, the working principle
Belt and weightlessness feeder is today the most used two kinds of weighing feeder type , but because they work differently and makes them their feeding accuracy factors
are not the same .
The weighing belt feeding process, when the sand vibrating screen material into the feeder , the material can form a substantially uniform material bed , and then is conveyed through a shear
gate ; when a thin layer of material quickly through the weighing section , feeder to detect the weight of the stone screening machine material ; according to the detected
Weight, belt speed can be adjusted continuously and automatically , so that the weight of material discharged can always controllable state. In contrast, in weightlessness
feeding method , the entire feeder, hopper and discharge of materials material continuously being weighed , so that the feeder
The output rate ( loss of weight of the feed rate of the system ) to be accurately controlled to achieve the desired feed rate .
Second, the feed material
Typically , the material determine the required feeder type. For those difficult to handle , it will overflow the flow of materials or difficult materials , it is best to
use weight loss feeder , which is characterized according to the specific materials are properly configured ; while not required for the free flow of feed material
Machine using any special configuration , use the belt feeder is the best choice .
Of course , this is just a general principle. For example, in plastics processing , due to feeding and handling of materials encountered in handling characteristics vary
widely , requires plastics processors should determine feeder technical specifications and selection stage , we should give full attention to the material properties of the
assessment
Evaluation. In order to give the material feeder with the correct match , plastics processors should feeder supplier in close consultation with the number of necessary
laboratory tests to confirm for selection .
Third, the weighing system
Whether you choose to or choose weight loss belt feeder , feeding must be accurate in order to ensure accurate weighing. The feed to the weighing belt , for a given
operating range , the required feed rate regardless of how much weight to be measured are relatively small and almost
Constant. Therefore , the belt of the weighing system the feed line loss of the process as so important.
Since the weighing belt feeding process is generally not required to configure the metering station on the operating range of the sensor is applied to measure the load ,
so the weight of the material requirements of the resolution to be lower. However, weigh belt feeder belt detection accuracy for any change in weight was
Are extremely sensitive , regardless of whether the change is caused by the material adhering to the belt caused by or due to the weight sensor zero drift caused . Impact
crusher feeding process requirements weightlessness weighing system has a wide operating range , excellent linearity , able to accurately determine the total system
Weight high enough resolution and in addition to the process for rapid measurements are required for high level of responsiveness. In addition, the low rate feed applications,
weight loss , if the detected total weight compared to the weight loss between the time very small, the measurement resolution of the
Level is especially important . This is because the process of weight loss not weighing the feed belt feeding processes that rely on stable zeros, which is the focus of the
weight changes , rather than an absolute measure of the weight values.
Fourth, the mechanical system
Because weight loss feeder mechanical structure is simple , people rarely worry about feeding accuracy problems . However, the belt feeder applications , feeding accuracy
may be affected by the impact of the weighing station dislocation . Specifically, it is directly in the weighing station upstream of the feed table with fixed
Weighing station itself, feed rate misalignment will cause unexpected increase or decrease. Additionally, any of the belt traction tension or cleanliness factors related to the
feed rate will result in an error . Therefore, in the equipment selection process and in the preparation of any maintenance program , they should
The operation of the system reliability and effectiveness assessed.
V. Control
Any feeder, whether it is a belt feeder , or weight loss feeder will configure a controller to perform the basic functions of equipment operation . In general , reliable
control function often depends on the accuracy of strengthening, while providing enhanced functionality is to create a
These conditions or to meet certain requirements. Compound crusher m weigh belt feeder process required enhancements include transportation lag delay , automatic belt weighing,
sprinkle overflow detection and many other items ; while weightless feeding process controls needed enhancements are included in order to solve environmental interference impact
Take the weight signal filtering, and the complexity of the feeder in order to add material stage to maintain volume measurement accuracy coupled with material provided by the
array control technology.
Six , environmental factors
Concerned about the operating environment of the feeder will often reveal to ensure reliable operation of the feeder method . Factors such as when the vibration is when
the measures will be taken with other devices feeder to isolate. These measures typically include the use of flexible joints as well as import and export of equipment
Damping device installed . Moreover, whenever possible, you should avoid high temperature , humidity, wind and other environmental factors on the impact of the feeder .
Seven , maintenance
Without a certain level of maintenance , it is impossible to expect precision equipment will work accurately . Therefore, proper maintenance is still very necessary.
Including: regular cleaning weigh belt feeder inside to avoid the build-up caused by the material feed error ; inspection
Belts for wear and adhesion of material on the belt , if necessary, to be replaced ; checks associated with the belt mechanical system is running correctly ; regularly inspect
all flexible joints , ensure a solid connection. If the connector is not tight , it will affect weight loss feeder weight measurement
Amount of accuracy.
