Crushing Plant
How should we do to improve cone crusher efficiency in crushing plant?
In order to ensure efficiency and quality in crushing and screening plants under optimum conditions, the design of crushing and screening plants, machinery and equipment should be designed by considering the geological and structural properties of the material to be crushed and produced and assembled by experts.
Crushing and Screening Plants are the facilities used for the processing of ores produced in the mining industry and for the crushed stone production (asphalt, concrete, road material etc.) in the construction industry.
It is not easy to create the necessary knowledge and experience to achieve a balance of quality and cost in material production. Because very different professional disciplines (mining, construction, geology, machinery, electricity and electronics, business, economics, etc.) must work in a team and in a coordinated manner.
In order to fulfill the needs of the construction industry, the material brought from the quarries by drilling-blasting and / or direct backhoe loaders are generally subjected to three different crushing processes.
As a result of these crushing processes, called primary (primary), secondary (secondary) and tertiary (tertiary), the material is passed through sieves and classified in desired sizes and the final stage of crushed stone (aggregate) production is completed.
Depending on the condition of the building structure, the process to be performed after that is operated by sending it to asphalt plants and reinforced concrete structures to concrete plants.
Crushed stone production can be checked to see the importance of crushing-screening machines. Crushed stone production takes place in 4 main stages. Analysis of cost ratios at this stage of production shows how important the meaning of crushing screening and therefore correct plant designs.
FACILITY DESIGN
One of the most important parameters in crushing and screening plants is the hardness degree and layer thickness of the stone. It is possible to increase the breaker clearance in hard and fragile (rigid) stones.
The fact that the stone is thin and medium layered (especially in sedimentary rocks) adversely affects the flatness index of the broken material. This helps the material to be leafy.
One of the conditions to be healthy in the crushing and screening plants is to remove the stone to be processed in accordance with the facility. In other words, drilling and blasting is done in accordance with primary breaker opening and healthy.
Dust from crushing and screening units, transportation and loading during operation damages the electrical electronic systems of the facilities, machinery and environment.
To minimize such damages, dry and wet filtration system (dust reduction systems) should be installed in crushing screening plants. In addition, the construction site and roads should be irrigated with irrigation sprinklers.
Electrical and electronic systems (panel and automation sections) should be kept away from dusty environments as much as possible. In order to increase efficiency, employees who have adopted the principles and principles of working discipline and trained should be used.
Crusher machine (primary, secondary, tertiary crushers), sieve and conveyor selection, plant and groove design, conveyor height and slope, sieve and crusher capacity (production capacity), feeder vibration, motor revolutions etc. in crushing screening plants. with the geological structure and chemical properties of the stone.
The primary parameters affecting the crushed stone (aggregate) quality are the shape of the stone’s crushing (compression crushing, crushing crushing) and the structural and physical properties of the furnace material.
These properties are determined in the laboratory environment and as a result of tests performed with certain international standards (hardness and frangibility index). Machine selection should be made according to these values.
The use of impact crushers (impacting the material to the liners and each other) for quality and cubic material production gives more suitable results.
The chemical mixture (chrome or manganese ratio) in the breakdown of the pallets and liners of the crushers in the crushing plants (primary, secondary and tertiary crushers) should be adjusted according to the chemical analysis of the material / ore and the condition of the working environment of the machine. Thus, wear on pallets and liners is minimized.
Limestone, sandstone, granite, basalt etc. Crusher parts and accessories of the same feature should not be used for different rocks. Castings produced for limestone and castings produced for basalt are different.
The manufacturing companies developing components that are suitable for the stone’s properties will decrease the cost of production by increasing the quality and efficiency of the crushing and screening plants.
