VEGA is a “Global Producer” for international cement and mining companies/plants and Large Plant producers in the cement and mining industries. Level and pressure sensors have been widely used for many years at different stages of cement production from crusher monitoring up to silo level measurement.
Sensors used in the cement industry must make reliable measurement under the challenging work conditions. Solid VEGA sensors are a maintenance-free devices with a long lifecycle, developed for any stage of the production.
We especially develop and provide following special solutions;
Cyclone Blockage Monitoring with Radiometric Measurement
Ensuring full process safety and mitigation of unintended production halts
Cyclones are used in clinker production for pre-heating the raw meal. Raw-meal is pre-heated at the temperatures up to +900 °C in the cyclone before being introduced into the rotary kiln for clinker production. This steam phase created by the raw meal which cools down and condensates while moving along the cyclones clings onto the inner surface of cyclone and raw meal in the pre-heating tower. As a result, a layering is created on the inner surfaces of cyclone in time eventually leading to the blockage. Continuous control of the layer thickness ensures the process to operate seamlessly.
SOLITRAC 31 and VEGASOURCE 31 Radiometric Measurement Devices
You can monitor the blockage by carrying out Radiometric Measurement in the cyclones in order to have conclusive and correct measurement results that are independent of the process conditions, and to ensure a complete process safety via detection of the adhered materials. A high level of plant productivity is achieved thanks to contactless radiometric measurement method.
It is possible to make timely interventions thanks to the cyclone monitoring. In some plants, said monitoring is also known to be carried out using pressure measurement method.
Also, cooling tubes are used to protect sensor against high temperatures, which remove the sensor away from the process.
For devices, having maintenance-free and a long lifecycle are two criteria that are important for plant managers and maintenance teams. As part of radiometric measurement method, limit level, proportional blockage, level and density measurement can be carried out continuously.
VEGA Radar Level Measurement and Limit Level Detection Solutions – Crusher
Level measurement and limit level detection in the crusher
Using explosion method, some pieces are broken off the bedrock to obtain rock pieces with a size that can be transported. In the later stages, these rock pieces are processed to obtain basic construction materials such as ballasts, chips or sand. Large rock pieces are crushed in different sizes using jaw crushers and cylindrical crushers. As a requirement of an economic operation, it is necessary to carry out both level measurement and limit level detection in order to minimize the wearing-off rate of the crusher.
VEGAPULS 69 – Radar Limit Sensor
You can carry out a reliable measurement in the crusher without having to deal with or take into account excessive dusting and weather conditions thanks to contactless radar level measurement.It will ensure high operational productivity since it is being noise-proof and will minimize your maintenance need thanks to contactless measurement method.
VEGAMIP 61
You can carry out limit level detection in crusher via microwave barrier. As a result, you will have
– An operation that is almost maintenance-free thanks to contactless measurement,
– Reliable measurement results even in existence of the high levels of contamination or adherence,
– External measurement thanks to the sturdy plastic or ceramic viewing window.
