The terms 'zaranda' and 'criba' refer to vibrating screens, essential equipment in the mining and processing industries used for separating bulk materials by particle size. In regions like Peru, Colombia, and Argentina, 'zaranda' is the prevalent term, encompassing various types like 'zaranda vibratoria' for vibrating screens and 'zaranda para clasificacion' specifically for classification purposes. The term 'malla de zaranda' refers to the screen mesh or media employed in these operations. In contrast, in Mexico and Spain, 'criba' is the equivalent term, which can include 'criba vibratoria' and 'criba de alta frecuencia' when discussing high-frequency screens. This terminology is crucial for effective communication within the industry, ensuring that professionals across different regions understand the specific type of equipment being referenced.
In formal engineering contexts, the universal term 'tamiz vibratorio' is often used, which adds a layer of technical clarity. Variants of these terms include 'harnero' in Chile, derived from the French 'harnereau', and 'cedazo', which is a more generic term for sieve or screen but is less commonly used in industrial applications. The choice of terminology may influence SEO strategies when targeting different markets, with 'zaranda vibratoria' attracting traffic from Peru, Colombia, and Argentina, while 'criba vibratoria' is more relevant for Mexican and Spanish audiences.
The physical components of a vibrating screen often utilize rubber and polyurethane materials for durability and performance. Rubber screen panels made from natural rubber (NR) or Styrene-Butadiene rubber (SBR) are designed for coarse screening applications, especially where heavy impacts are expected. On the other hand, polyurethane screen panels, typically rated at 85-95 Shore A hardness, are utilized for fine screening tasks, offering a service life that can be 3 to 5 times longer than traditional wire mesh options. Additionally, rubber isolation mounts play a vital role in supporting the screen deck and isolating vibrations from the surrounding structures, improving operational efficiency and reducing wear on the equipment.
