ИСПОЛЬЗОВАНИЕ РАБОЧИХ ОРГАНОВ С ДИСКРЕТНЫМИ ПОКРЫТИЯМИ ДЛЯ ПОВЫШЕНИЯ ЭФФЕКТИВНОСТИ ДРОБЛЕНИЯ ЗЕРНА

The article discusses the influence of the working surface of crushing elements with a coating of a discrete structure having a relief in the form of hemispheres located on a plane on the destruction and grinding of grain raw materials during its free impact. It is shown that the working surface of crushing elements coated with a discrete structure with a hemispherical relief, not yielding to a plane in a direct impact, can be much more effective in grinding grain raw materials if the angle of incidence of grain is increased. The theoretical justification and experimental results are given for grinding wheat grain by crushing elements with a working surface with discrete structure coatings.
