Trantec also offers Gravimetric feeder systems. These are sometimes known as ‘Loss in Weight’ feeders. These consist of a weight system and a control scheme.
The main purpose of a Gravimetric screw feeder system is to discharge process material a controlled weight-based rate and must also meet three main requirements.
1. Material Handling
A Gravimetric Feeder’s main purpose is to weigh material to achieve a required feed rate.
Trantec are specialists when it comes to providing solutions for many industries within bulk solids handling. We are a leading screw feeder manufacturer and have contributed towards this by introducing specialist Powder Feeders.
This article will reveal exactly what is meant by a this type of feeder and how it can help many industries process materials.
There are different names associated with this type of feeder. However, despite this, it is important to focus on the main benefits that are associated with this feeder. Since the main function of a Gravimetric feeder is batch size then one must also understand that this type of feeder is a closed loop. The latter controls the speed of device to control the feeder’s accuracy. In addition, Gravimetric feeders use real-time devices that focus on meter rate at a constant weight per unit of time. This weight is usually measured using a load cell.
The most popular type of Gravimetric feeder is the loss-in-weight feeder. This usually consists of a hopper and a feeder. As the material is discharged the system weight is reduced. The loss-in-weight controller controls the speed of the feeder. These feeders are useful for materials that vary in physical characteristics and the meter and control the rate of discharge regardless if the material changes or not.
Having an efficient material handling system is crucial in the solids and bulk handling industry. To achieve efficiency and accuracy, Trantec design and manufacture loss-in-weight feeders that meet the needs of our customers.
Therefore, it is imperative that accuracy and control are at the forefront and that the feeders provide the ultimate solution when it comes to conveying materials. This article will examine the impact of loss-in-weight feeders and how they work. It will explore the popularity of loss-in-weight feeders and why they remain to be the most preferred choice amongst many different industries.
One of the critical requirements in today’s advanced technological environment is reliability and accuracy. The beauty of Trantec loss-in-weight feeders is that they are highly reliable and are, therefore, able to achieve accuracy of +1% to 2% typically. This is a reflection on the development and work gone towards the feeder in ensuring that it is equipped with robust, durable features.
Trantec offers a range of different rates for the diverse range of loss-in-weight feeder systems.
The beauty of Trantec feeders is that they are able to tackle a big issue in the food and pharmaceutical sector – product contamination. These feeders are equipped with features that avoid this and lend themselves for such applications.
These powder feeders can be utilised in many ways: continuous metering with control, wild flow and a batching feeder. These type of powder feeders are usually divided into two categories – continuous and batch. Furthermore, feed accuracies vary.
