Abstract (AI)
In wheat milling, it is particularly necessary that the grist particle size-distribution entering and exiting each plansifter compartment of the wheat mill to be determined so that the appropriate geometrical characteristics of flutes, grinding rolls and their functional parameters can be chosen and the characteristics of the sieves braids to be established to optimize flour, middling, and semolina yield and quality of them. The paper presents the particle size-distribution of wheat going through each break, in a five-break roller mill system with a capacity of 4.2 t/h and equipped with a semolina sorting compartment (divisor). The particle size distribution data where fit to the Rosin-Rammler distribution equation.
Key Findings
1
Particle-size distributions are characterized for wheat material passing through each break of the milling system.
2
The investigated roller mill system has five breaks, a 4.2 t/h capacity, and includes a semolina-sorting compartment (divisor).
3
The measured particle-size distribution data are fitted using the Rosin–Rammler distribution equation.
4
The study determines wheat grist particle-size distributions entering and exiting each plansifter compartment in a five-break roller mill system.
5
These distributions provide a basis for selecting roll flute geometry, grinding parameters, and sieve-braid characteristics to optimize flour, middlings, and semolina yield and quality.
