بيت /silica content wear on crushing plants
Plant–herbivore interactions are hypothesized to drive vole population cycles through the grazinginduced production of phytoliths in leaves. Phytoliths act as mechanical defences because they deter herbivory and lower growth rates in mammals. However, how phytoliths impair herbivore performance is still unknown. Here, we tested whether the amount of phytoliths changes tooth wear patterns.

Crushers or rock crushers are machines used to reduce the size of rocks and stones in aggregates production, construction material recycling applications, and in mining operations. Every crushing plant and crushing process has its own requirements and demands. has designed, engineered and manufactured crushers for more than 100 years.

Even though it is poorly soluble, silica occurs in many plants. Plant materials with high silica phytolith content appear to be of importance to grazing animals, from chewing insects to ungulates . Silica accelerates tooth wear, and high levels of silica in plants frequently eaten by herbivores may have developed as a defense mechanism against predation.

Silica Rule. Thanks to the decade of work by the Silica/Asphalt Milling Machine Partnership, use of OSHAapproved engineering control technologies can ensure compliance with the rule for roadway milling activities; however, other road construction and asphalt production activities may trigger the Silica Rule's monitoring and mitigation requirements.
