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.
In 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).
Cleaning 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.
