Granite Crushing&Screening Plant in Nigeria

Type: Fixed(mounted on concrete foundation)
Max Feeding Size: 150mm
Final Output Size: Stone Base, Aggregates
Capacity: 10-20TPH

At the very beginning, DELY-DAD NIG LTD purchased 2sets small jaw crusher PE250x400 in 2008, which is to produce stone base, aggregates by manually feeding stone to these 2 jaw crusher. One year later, they earned money and expanded the production line. On August 24 of 2010, they purchased bigger jaw crusher PE500x750 and PE400x600, vibrating feeder, vibrating screen and belt conveyors, which realize semi-automatic production.

Their project is located in Ibadan. The raw materials were excavated from the ground using a hook machine, and it is said that they can excavate to a depth of 7 meters. The granite underground is excavated and fed to jaw crusher PE250x400 manually, then screened to dust, 1/4”, 1/2”, 3/4” and 1”.

They had expanded their plant from 10-20tph to 30-50tph in 2010. They are planing to expand again by using bigger jaw crusher and bigger cone crusher when exchange rate between USD and Naira is changing better.

Regarding cone crusher, we have spring type, single cylinder hydraulic type, multi-cylinder hydraulic type for choice. They have their own advantages as below:

For spring cone crusher:

1.Simple Structure: Spring cone crushers have a straightforward structure, making them easy to operate and maintain.
2.Lower Cost: They tend to be more cost-effective initially compared to hydraulic cone crushers.
3.Good for Medium-Hard Materials: Spring cone crushers are suitable for medium-hard to hard materials.

For singly cylinder hydraulic cone crusher:

1.High Efficiency: These crushers offer higher crushing efficiency and better product shape due to the hydraulic adjustment and hydraulic clearing systems.
2.Adjustability: The hydraulic adjustment system allows for easy and precise setting changes to achieve desired product sizes.
3.Less Downtime: Hydraulic clearing reduces downtime by quickly clearing out any uncrushable materials.

For multi-cylinder hydraulic cone crusher:

1.High Crushing Efficiency: Multi-cylinder cone crushers have superior crushing efficiency, especially for hard materials.
2.Greater Production Capacity: These crushers can handle larger tonnages and produce more cubic-shaped products.
3.Better Automation: Multi-cylinder crushers often come with advanced automation features for better monitoring and control.

In summary, the choice between these cone crusher types depends on factors such as the material being crushed, desired product size, efficiency requirements, initial and maintenance costs, and the available skill level for maintenance and operation.

Wish their dreams come true very soon and choose hydraulic cone crusher as secondary one in future.
