Analysis of batching accuracy to the main reason for the lower right, it can be seen proportioning system is a complicated automatic control system

In order to ensure the accuracy of the ingredients , it is necessary to carry out comprehensive analysis according to the requirements of the process and the characteristics of the required materials . Controlling the high precision of the batching system is beneficial to improving the quality of the products, which is a highlight of the strength of the enterprise.

First, the material characteristics

Mainly refers to the fluidity of the material, the moisture absorption, the uniformity of the shape of the material and the viscosity of the material. These factors directly affect the flow of the material during the formulation process , which affects the accuracy of the ingredients.

Second, the control of the amount of feed

1, Level of influence in the silo: silo material level is too low or lack of material likely to cause feeding can not reach the set value,

2 , feeding speed : feeding speed index and feeding accuracy index are contradictory , speeding up the feeding speed , can reduce the batching time

While the ingredients required to improve accuracy, it is necessary to extend the feeding time.

3, the feeder discharge port to the weighing hopper height: cutting the power feeder, to stop the feed, self-feeder to the weighing hopper an intermediate blanking air (gap) is the main error sources influence the accuracy of dosing First, the feeder discharge port to the weighing hopper greater the height, the greater the value of the drop, the more difficult to control the accuracy.

Third, weighing hopper

If the material is less prepared each time in the system, the weight of the weighing hopper will affect the choice of the weighing cell range. The stiffness of the weighing hopper also affects the force applied to the sensor. Http://
