Secondary crusher and tertiary crusher

Secondary crusher usually processes the products of primary crusher and it can process the particles into smaller sizes. Secondary crusher can process materials with a harder strength, such as below 350Mpa. NFLG supplies five kinds of secondary crusher: European type jaw crushing plant , PFW series impact secondary crusher, spring cone crushing plant, hydraulic cone crushing plant and CS cone crushing plant.

Tertiary crusher helps to crush stone materials into smaller particles, even as tiny as powder. It can be used in the final parts of the crushing process. Tertiary crusher, sometimes, can be used as grinding mill . NFLG designed tertiary crusher recently and won a great success: HCS90 cone crushing plant and CS cone crushing plant is well sold and widely welcomed by our customers.

Crushed stone (aggregate) Secondary crusher and conveyor

Rock leaving the primary crushed typically is 8 inches in diameter or less. This crushed rock is moved to the secondary crusher by a conveyor belt (see left). The secondary crusher is located at the large horizontal conveyor belt which separates ‘rip rap.’

At the secondary crusher the crushed stone passes over a ‘ screen ‘. Stone greater than 8 inches in diameter are separated for ‘rip rap.’ The horizontal conveyor carries the rip rap to a stock pile (see below) where it is ready for shipping. Rip rap is used for soil erosion control.

The crushed stone that passes through the 8 inch screen is crushed to smaller size in the secondary crusher known as a ‘ cone crusher .’ The cone crusher reduces the size of the crushed rock to a mixture of crushed rock sizes that are used to construct roads, offices buildings and homes, and for rail road track beds. This crushed stone is transported to the sizing plant that at this mine is located on the surface. The sizing plant separates the different sizes of crushed stone.

Secondary Crusher Benefits

The difficulties of broken clay, almost breaking it off in the secondary. Breaking and crushing coarse clay, although there are some difficulties, but has basically been resolved.Users want to shreds breaking is: a broken discharge is less than 65mm, less than two broken 15mm, yield ~ 45t / h, sodium handling, but in the country has not broken to find a suitable model.

Primary crushing roller breaking space instead of increasing the secondary crusher, but the wear is too severe, the finished product size, production can not meet the requirements. Moreover, since the crushing ratio is too large (65/1.6), must be set at least two broken, so that each of the wear and tear caused by severe and greatly increased power consumption. Increase in power consumption did not increase grain size and yield of qualified products, but increased consumption of wear and tear.

Therefore, both from an economic point of view, or from the configuration of rationality, efficiency of resource use, said a pressing need to increase the appropriate secondary clay crusher. The main secondary crushers are impact crusher (Hydraulic impact crusher, PE series impact crusher), cone crusher (CS cone crusher, Hydraulic cone crusher, Spring cone crusher) and Vertical Shaft impact crusher.

Secondary Crusher To Clay

Clay Secondary Crusher has a wide range of uses, the hardness is not high, but the clay processing, especially in deep processing, fine processing is more complex. As the clay sub-crystalline and amorphous material, water layer, generally 15 to 28% moisture content, a larger viscosity, specific gravity heap 0.8 ~ 1t/m3, thus breaking them become more difficult.

Some professional institutes, design and development of the 2PGC1250x1250, 2PGC1400x1400 Double Roll broken clay to solve the cement industry, the material requirements of 35 ~ 70mm in size, but it can not meet the requirements of crushing process.

Secondary Crusher – Classification of Secondary Crushing Machine

rock crusher , also known as ore crusher , plays a vital part in crushing various types of rocks and ores. There are two types of rock crushers in actual production, that is, primary crusher and secondary crusher. Secondary crushers mainly handle rocks of smaller particle size that have already been impacted and crushed from their original size. In recent years, with the rapid development of infrastructure projects, rock crushers have found more applications in various fields and industries, such as mining , chemical industry, road construction, metallurgy, construction and so on. In this passage, several types of commonly used secondary crushers will be listed as follows.

1. Impact Crushers

According to the nature of the materials to be crushed in actual production, impact crushers can be used for secondary crushing as well primary crushing. During operation, materials will be first fed into the crushing chamber for continuous and repeated impacting and crushing by large hammers. When the materials have been crushed to the proper particle size, they will finally be discharged from the lower part of the discharge opening. In general, impact crushers can be divided into two types, including horizontal shaft impact crusher (HSI for short), which uses hammers that swing on a rotating shaft, and vertical shaft impact crusher (VSI for short), which “throws” the material against a surface by means of the rock’s velocity to break it apart.

2. Cone Crushers

As a type of frequently used secondary crusher, cone crusher’s working principle is quite similar to that of the gyratory crusher . Nevertheless, the difference is that the crushing chamber in a cone crusher isn’t as steep as it is in a gyratory crusher and the positions of the different crushing zones are more parallel.

3. Gyratory Crushers

Gyratory crushers mainly operate by pressing between two components–an eccentrically-gyrating spindle and an enclosing concave hopper. The spindle is covered by a wear-resistant mantle, which makes the spindle more firm and durable. The materials to be crushed will be continuously compressed and impacted as they work their way down the crusher. When the particle size has reached the standard, the materials will be finally discharged from the bottom of the discharge opening.

4. Roll Crushers

The name of roll crusher properly indicates its operating mode. The rocks and ores to be crushed will be processed between two large steel wheels, which press down on the materials and then crush the materials into smaller particle sizes to meet customers’ specific requirements.
