bulk bag filling systems
Transportation balance
A bulk container system, with 40 per hour bulk bags filling must "hello" production process and system of the upper, conveys the product positioning, bagged at the same speed - product must equal the product.This can be accomplished in two ways.
Usually, the line will continue to transfer large well (50 tons of ability). Most of the preweigh bagging system and well below, if the occurrence or bagged continuous production can keep up with most bagging rate, or periodic output, the appropriate level to fill. A common arrangement is the continuous production rate and scored product unceasingly to pack line is constant volume fibc.
Weighing
Weighing subsystem design is the biggest challenge is preweigh bulk container system implementation. Like the previous article, in every hour, 40 bales of system, the cycle time of 90 seconds. 15 seconds, assigned to preweigh emptying hopper (vessels products is shooting into big bag). Cycle time - 75 seconds, can be used to measure future shot.Assuming a typical dribble feed duration of 15 seconds, the fast fill portion of the weighing cycle is 60 seconds.
Usually, 50-100 pounds weight is always shoot. Dribbling, this means that in 2000 pounds bags, increasingly pounds of product must flow to preweigh hopper 60 seconds. This is equivalent to a high transient flow, 117,000 LBS/hour.Two key factors must be considered to maintain accurate and consistent weighments:
1. Control. The device used to meter the product into the preweigh hopper must be properly selected.
2. Rate. The rate at which the product flows into the preweigh hopper must be consistent from bag to bag.
There are a number of ways to design such a weighing system according to the desired weighing accuracy and capital budget.
Note that preweigh systems can be designed to consistently maintain accuracy of +/- 2 lb.
Stability
The less the faster, most of time is filled with the bag is available for densification. Further, the stability and worry, because most of the bag filling rate increases. As the bags of 25 per hour scattered bags, beyond, stability and densification has become the main concern and almost all the products -- especially if the bag is most requirements.In a preweigh system capable of filling 40 bulk bags per hour, the filling machine must be carefully designed to ensure the filled bags are stable and safe.
In the next article we will look at when a preweigh bulk bagging system should be used
