Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rockThe rule of thumb for the Double Roll Crusher’s ratio of reduction is 4:1. The simplified design gives these units excellent reliability and requires very little maintenance. The crushers are designed with built-in tramp relief that McLanahan Double Roll Crushers

double roller crusher and to predict the particle size distribution of the broken products. Soni S K [3] had established a model describing the particle breaking behavior of a smooth double roller crusher for the study of product particle size distribution. Cleary P W [4] simulated the crushing model by usingDouble-roll crushers are able to crush more finely than single-roll crushers, because they are designed with teeth that mesh together rather than rotating past a smooth plate. They can reduce coal to as little as ¼ inch (0.6 cm) topsize, although they are more commonly operated close to 2 inches (5 cm).Roll Crusher an overview ScienceDirect Topics

Abstract. Since for granulation processes the crusher operation has a decisive influence on the system stability, a reliable mathematical model to represent an industrial double-roll crusher of a urea granulation circuit is provided in this work.

The machine was fabricated using locally available materials. The fabricated stone crusher was tested and the actual capacity was found to be 301 kg/h with a through-put efficiency of 75.4 %. TheThe design has been developed for a single-roll crusher with the forced supply of destroyed material into the crushing zone [].The capture of a crushed piece occurs due to the stop located on the roll (see Fig. 1); in this case, the condition for formation of a complex stress state in the crushed piece is observed, and the energy consumption is Capacity Calculations of the Crasher with Stops on a Roll

The Double Roll Crusher crushes a wide range of material types reaching compressive strengths of up to 150 MPa and even above. It is less sensitive to wet and sticky material than Roll Sizers and can take in larger feed sizes making it the optimal primary crusher for soft and medium hard rocks. PDF (2227KB) Download. FLS Double Roll CrusherToothed Double Roll Crusher is used for Secondary and Tertiary Crushing of soft to medium hard material like lignite, coal, fertilizer, gypsum, chalk, clay, limestone, coke, sinter, etc. OPERATING PRINCIPLE Due to inward opposite rotation of the rolls, the feed material is nipped between the rolls and crushed by piercing and compression.5.imimg
