Production of montan wax
In an opencast mine brown coal with a very high content of wax is mined. From this coal raw montan wax is obtained in different process steps. The wax granulate, obtained in spray towers, is measured with the SolidFlow 2.0 in freefall in a downstream pipeline. With the continuously detected material quantity disruptions in the production process can be detected promptly.
Measurement of fine lime after a ball mill
A lime plant produces a wide range of products. Among others lime is ground in a ball mill to fine lime. The mill discharge is removed via screw conveyors and then measured in freefall by the MaxxFlow HTC. The use of the MaxxFlow HTC in different manufacturing processes simplifies the billing of processed material quantities.
Replacement of baffle plates in lime plant
In a lime plant in Poland there was a request to measure the amount of extracted lime in free fall after an air slide. Our customer had previously used impact plates, however this solution was not optimal and it always led to problems with mechanical components.
Polystyrene sheets production
In the production of polystyrene sheets the EPS granules (polystyrene granules) are delivered in pressurized containers and is then transported into silos. The ﬁlling and removal takes place via a disc conveyor. So far, the quantity was determined by the level measurement in the silo. Our customer was now looking for an optimized quantity measurement.
Production of plastic granulate
In the production of plastic granulate, it is mixed with various additives for a range of applications.The customer’s objective is to continuously measure the quantity of plastic granulate conveyed in order to optimize the admixture of additives in terms of quantity with this reference variable.
Exact measurement of flow rate
At a limestone manufacturing site, limestone is mined in a quarry and afterwards ground and transported to a silo. The material is transported into the silo via a pneumatic line. The quantity of limestone was determined on the basis of the theoretical data provided by the plant operator’s employees, however, the objective was to measure the material flow rate continuously.
Information about the quality of flow condition
Fly ash does have the tendency to create blockages in the cone of the hopper and screw feeder. Our customer was looking for a solution to provide information about the quantity of material flow behind the hopper to control the flow condition. The flow measurement will give online information that provides important conclusions about the quality of the material transport. For example, blockages in the silo cone and in the rotary valve can be detected.
