It offers low dust and abrasion rates as they break the material by compressing it.
Body Structure:
The body consists of two parts, the upper and lower. The inner surface of the upper section is covered wicone crushersth concave.
Cone CrushersCone crushers, It is in the form of an inverted truncated cone. According to the size of the breaker, it is reinforced with horizontal and vertical belts.
It is made of cast iron or cast steel. In very large crushers, they are made in pieces, and the parts are added together with strong and thick bolts, and the body is formed.
The lower part of the body is a protector and carrier. The bolts to which the hammer is attached to the foundation are passed through the holes located here.
It has a structure suitable for placement of the eccentric sleeve and bevel gear in the middle part where the lower extension of the shaft enters.
This part also carries the main drive pulley and the shaft (pinion shaft) bearing. Cone crushers Like the upper compartment, it can be reinforced with vertical and horizontal belts depending on the size of the hammer.
A groove structure suitable for the broken goods to come out of the crusher is also part of this section. The upper and lower sections of the body are connected by bolts passing through their mutual flanges.
Mouth Ring and Bridge:
The upper end of the body is surrounded by a mouth ring. The bracelet also carries the bridge, which is suitable for the upper end of the hub to pass.
The mouth plate is covered with a wear plate (liner) as the material is fed to the crusher through the upper mouth of the body.
The mouth and bridge can be built in one piece.
As the bridge is important in terms of crusher blockages, it is curved upwards and with two or three legs as it is important for the bridge to close as little as possible. The top of the feet is covered with protective plates (lining) against impacts and wear.
Mouth collar lining and bridge foot lining are usually made from the same material as concave. In the middle of the feet, the egg-shaped part has a structure where the upper end of the hub shaft will enter.
Cone crushers, If the main shaft is of the type suspended from the bridge, this section has a structure according to it.
With the eccentric movement, a spherical bearing structure is noticeable here, since the shaft is constantly making a secretion.
Also included in this section is an adjustment device that allows the hub to be pulled upwards to accommodate wear and adjust the throat opening.
Hub and Main Shaft:
The main shaft is sized to withstand the forces and shocks arising from forged steel and breaking action.
The middle is more bulging, thinner towards the two ends. It passes from the upper end to the slot in the middle of the bridge and from the lower end to the eccentric sleeve in the lower body.
Cone crushers, The part of the navel that comes to the crusher zone is in the form of a cone with a wide top and a narrow diameter.
A second conical part, which passes into this conical part, carries conical hub linings on its upper surface.
Since the core movement is an eccentric secretion, there is a good felting requirement between the core and the lower body.
Such a felt is very important to prevent the fine parts and powders that will come out of the crushing process from damaging the moving parts in an oil cycle.

Crusher machine (primary, secondary, tertiary crushers), sieve and conveyor in crushing screening plants selection, plant and gutter design, conveyor height and slope, sieve and cone crusher capacity (production capacity), feeder vibration, engine revolutions etc.
With the geological structure and chemical properties of the stone should be done.
The maximum capacity and quality of the crushing screening plants, which are designed to produce the products to be produced for the construction industry (0–5mm / 5–12mm / 12–18mm / roadbase / subbase / armor), are designed for dry and clean material / ore environment.
Cone CrushersIn other words, dry and clean stone is an ideal working material for crushers. If the material / ore coming from the quarry is not homogeneous and the formation used contains geological process with crusher fractured and cracked surfaces with the effect of different structural movements, siliceous, clayey and iron oxide zones are formed with the effect of crushing, deterioration, decomposition and alteration during these discontinuities.
Since these zones are intertwined with solid stone, they negatively affect the structure and color of the material.
Especially when working in rainy weather and / or under groundwater level, this interaction increases even more.
If the material coming to the crusher is dry in such quarries, the decomposed, degraded and grounded material is easily removed from the system by eliminating it from the feeder grills before coming to the crusher.
An example flow chart is given above. From the flow chart prepared in accordance with the single product purpose, capacity information and equipment selections for each equipment can be seen easily and clearly.
However, if the material is wet and moist, bypass operation cannot be done completely;
By plastering, sticking and clumping, some of the defective material enters the production system and adversely affects the quality of the final products; as well as bunkers, etc. It adheres to the feeder edges in the primary chamber and slows the flow of material to the crusher, negatively affecting the production capacity.
In addition, wet and uncleaned material causes clogging of the gutter and sieve (especially in stone dust sieves).
Cone CrushersCleaning them is also a waste of time and work. Another negative effect of breaking wet and wet material in rainy weather is that it causes the conveyor belts to slip and skid.
Another negative aspect of crushing wet and wet materials is that the secondary and tertiary Cone Crusher blades wear more easily and quickly with the effect of water.
Since the sieves cannot handle wet and damp material well, especially 0–5mm will plaster the eyes, it will come out 5–12mm and even 12–18mm dusty. In addition, rainy weather causes an increase in the residual material in the hearth.
In other words, some of the material that can be broken under normal weather conditions is removed from the quarry as excavation material.
Cone Crushers This causes an increase in production cost. In order to operate the furnace machines in a healthy environment, the furnace water must be drained in a controlled manner.
Some of the water; It is possible to obtain healthier results by irrigating roads, dust suppression system, and by occasionally washing and breaking the dirty material in the furnace.
Thus, both the pollution rate in the material and the dust rate from the crushing screen are minimized.
