Cyclone (cement) – buildup measurement | VEGA

In clinker production, cyclones are used to preheat the raw meal. Before the raw meal enters the rotary kiln it is preheated to +900 °C in the cyclone. Constant monitoring of the buildup thickness on the walls ensures a continuous process.

Clinkerization

In this way raw meal passes from top cyclone to lower cyclone (bottom cyclone but one) and enters calciner at about 800 0 C. As a whole the heat transfer process is counter current as feed moves from top to bottom and hot gases from bottom to top, however in actual the whole heat transfer takes place in co-current heat transfer mode.

[PDF] Design of High Efficiency Cyclone for Tiny Cement ...

Cyclone is considered to be cheaper having low maintenance cost. The present paper aims at designing of high efficiency cyclone by using STAIRMAND METHOD for a tiny cement plant. The efficiency achieved with this design is of the order of 91.1 %. The tiny cement plants are having a capacity of ranging from 20tpd to 50tpd.

Gamma

The Problem Blockages occurring in Cement Plant Cyclones and/or Cyclone under flow pipes can be dangerous and difficult to detect. These typically occur as follows:- Under normal conditions the cyclone under flow pipe is never full of material. Abnormal changes in the process can sometimes result in blockages in this underflow. Hence gamma type blockage […]

The cyclonic chamber used here was based on one in the Dibb and Silva (1997) paper. They used a software based on Silva''s model (Silva, 1991) to study theoretically the influence of cyclone geometry on APRT. Assuming constant inlet velocity, they observed that cyclone diameter was the most influential dimension.
