Abstract
The particle size distribution of dust in the air of the work area has been determined for some cement plant shops. An experimental study has been conducted to explore the effects of microclimate parameters on the dust particle size distribution on the shop floor in the cement milling shop and cement packing shop, and regression equations have been obtained. A mathematical model has been developed to forecast the dust particle size distribution in the air of work areas of cement plants.
Highlights
The main sources of dust emission in the process shops of cement production facilities are mills, kilns, belt, scraper or tray conveyors transporting dusty materials, as well as cement screening and packing machines
The dust situation in the work area is largely determined by the microclimate parameters; there has been a lack of attention to the effects of temperature, humidity and mobility of the air in work area on the content of particulate matter in the cement production process [3]
To determine the particle size distribution of cement dust emitted by the Sebryakovcement plant in Mikhailovka, Volgograd Region, an experimental study was conducted focused on the distribution of dust particles in the air of the cement milling shops, near the mill feeder, in the rotary kiln operator's work area, and in the cement packing shop in the packing machine operator's work area
Summary
The main sources of dust emission in the process shops of cement production facilities are mills, kilns, belt, scraper or tray conveyors transporting dusty materials, as well as cement screening and packing machines. The dust levels in various work areas of cement plants may be tenfold the rated parameters or even greater [1]. The leading causes of shop air contamination with dust are: insufficient equipment containment, incorrect sizing and design of local exhausts, low efficiency of dust aspiration systems, open transportation of dusty materials. The dust situation in the work area is largely determined by the microclimate parameters; there has been a lack of attention to the effects of temperature, humidity and mobility of the air in work area on the content of particulate matter in the cement production process [3]
