Roll crusher, as one of the most economical and practical crushers, is designed to handle the first and second crushing of friable minerals and stones such as coal, clay, coal gangue, limestone, slag, cement clinkers, and shale, etc. With many improvements and upgrades, the FTM roll crusher has reached the international level and ranked among
Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing.
Crushing mechanism and model . 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
Double roll crushers help producers achieve the strict coal specifications they need to meet. Used as a primary or secondary unit, double roll crushers can be used in nearly any application with even the hardest, most abrasive material. This efficient crusher can lower power requirements for producing material and, with its unique features, can

Roll crushers, or crushing rolls, or double roller crushers, are still used in some mills, although they have been replaced in most installations by cone crushers.
When the repair is started, the crusher is started, and the roll is cut by a manual feed mechanism (conditional automatic feed mechanism can also be used). The following points should be noted when applying this method: ① The trajectory of the tool holder is parallel to the axis of the roller to avoid taper after cutting and affect the
Double roll crusher is one of the common crushing equipment in sand production line, with the characteristics of small size, low noise, simple structure, easy to maintain, etc. For the major enterprises, improving the production efficiency of the roller crusher has always been their most concern.
Figure 5.1 Schematic diagram of a crusher showingg the open- and closed-side settings. 5.1 Jaw and Gyratory Crushers. Jaw and gyratory crushers are used mostly for primary crushing. They are characterized by wide gape and narrow discharge and are designed to handle large quantities of material. The capacity of the crusher is determined by its size.
The mechanism of jaw crusher is based on the concept “crushing without rubbing”. Jaw crushers consist of two jaws. One fixed and the other reciprocating. The opening between them is largest at the top and decreases towards the bottom. The pitman moves on an eccentric shaft .
