Crusher also can be classified according to the working principle and mechanical structure.Jaw crusher.When the movable jaw plate close to the fixed jaw plate, creates a squeezing force act on the stone.In addition, there is jagged steel on the rock material contacting surface of the fixed plate and fracture.When the movable plate apart from the fixed plate, the crushed material is discharged under the gravity force.The process of crushing is that the process of breaking large particle material into smaller size under the action of external force.In industry applications, the size reduction task mainly depends on the mechanical force.Because of the jaw crusher working principle that crushes the material by reduced space between two plates, the aggregate product often has a high content of needle shape, which is not suitable for asphalt processing road construction.Therefore, the jaw crusher is widely used as primary crusher rather than secondary crusher in the mineral processing, aggregate processing industry.
The other one is cone slag crusher, which is is ideally used for crushing slag in the secondary process after jaw crusher.The material crushed through jaw crusher will be fed into cone slag crusher.
Primary and secondary crushing as the first step of cement production line is of crucial importance, so is the selecting of cement crusher plant.There are many types of crushers that can be used for primary and secondary crushing, such as jaw crusher, impact crusher, hammer crusher and cone crusher; a specific introduction about the difference of various types of crushers is as following.
Why does this matter? lighter crushers sometimes have flexing in the frame which can lead to cracking this rarely happens with the grizzly king jaw crushers reinforced design.Big reinforcing ribs provide frame rigidity and add to the weight of the crusher, making it heavier.The stiff frame maintains good bearing alignment, which means prolonged bearing life.

Asking about the minimum setting of rock crushing equipment will give you the significant information you need about how small the crusher can break down material.For example, a primary jaw crusher will typically have a minimum setting between 4 and 6.To further break down this material, your secondary and tertiary crushers will need to have smaller minimum settings.Reduction ratios also come into play when considering how small material will be broken down between the three stages in the crushing process.Often, between primary and secondary crushing, you may expect to see an 8 to 1 reduction, which can be easily achieved with a cone crusher.From there, youll need to know how fine your final product needs to be so you can choose the right tertiary crusher.For example, fine cone tertiary crushers typically have a minimum setting of about 3/8.
Jaw crusher and impact crusher are the main crushing equipments in the ore crushing production line.Jaw crusher is mainly used for the process of high hardness materials, mainly for the coarse crushing of ore, while the impact crusher for the treatment of medium hardness and brittleness stones, mainly for the medium crushing and fine crushing of stones.
Basically, the materials of the crushed stone are limestone, traprock, granite, argillite, quartzite.Although they are huge blocks at first, after the processing of different crushing machines at a different level, itll be crushed to the desired size.In general, the crushed stone has to get through the two or three levels of crusher which means it should be reduced by the primary crusher like pe jaw crusher then the secondary crushers like cone crushers or impact rock crushers and finally the tertiary crusher.
The development of the gyratory crusher has a history of 100 years.Due to its large processing capacity, large ore size, and ability to handle hard ore, it is still important equipment for crushing various hard materials in large mines and other industrial sectors.The rotary crusher has large production capacity, low unit power consumption and stable operation.It is suitable for processing sheet materials.The crushed product has a relatively uniform particle size and can be widely used for coarse crushing and medium crushing of various hardness ores.However, compared with the jaw crusher, the structure is complicated, the price is high, the maintenance is difficult, the repair cost is high, and the capital construction cost is high.
1.Jaw crusher deep crushing cavity, which improves the feeding capacity and output; large crushing ratio, uniform product size; reliable and convenient gasket-type discharge opening adjustment device, big adjustment range, increasing the flexibility of the equipment; simple structure, reliable work, less operating costs, energy saving.A single machine can save energy by 15% ~ 30%, the system can save energy more than double; the adjustment range of the discharge port can meet the requirements of different users; low noise and less dust.2.Impact crusher the clearance between the impact plate and the hammer can be easily adjusted, effectively controlling the discharge particle size, and the shape of the discharge particles is good; the structure is compact, the machine is rigid, and the rotor has a large moment of inertia; the high chrome plate hammer has high impact resistance, wear-resistance and large impact convenient maintenance, economical and reliable; full crushing function, high productivity, low wear of machine parts, high comprehensive benefits.
