Akaki, Cameroon - 3 million tons per year

Société Transatlantique Cameroun Sarl (hereinafter as Transatlantique) is mainly engaged in the production and sales of various building stones. In the akak1 area of Yaounde, the capital of Cameroon, Transatlantique has obtained the mining right of a granite mine with reserves of about 12 million tons, producing and selling 1 million tons of stone annually. Through careful calculation and construction, Meilan design team overcame all kinds of tests, and finally completed the installation, commissioning and operation of the production line on schedule, And the project meet the requirement of quality, quantity and zero accident.

First-level crushing:The rubble material is transported by the mining area, and is evenly thrown into the MJ125 jaw crusher through the rod feeder MGD1360 for coarse crushing. The coarsely crushed material enters the semi-finished product center warehouse through the belt conveyor.

Secondary crushing:The material is sent from the central warehouse of semi-finished products to the MC300Z cone crusher through the belt conveyor for secondary crushing, and sent to the primary screening through the belt conveyor (2 sets of 2MF2470 vibrating screens, the upper sieve hole 31.5mm*31.5mm, the lower layer 5mm*5mm ) Upper classification, the upper 31.5mm material enters the semi-finished product buffer storage, the bottom 0-5mm material is sent to the finished product ridge for stacking, the middle 5-31.5mm material is sent to the third screening (2 2MF2470 vibrating screens, the upper screen hole 20mm*20mm, the lower layer 10mm*10mm) is screened, and the screen is divided into 20-31.5mm, 10mm-20mm, 5mm-10mm finished product stacks.

Three-stage crushing:The material is sent from the semi-finished product buffer storehouse through the belt conveyor to the MC300X fine crushing cone crusher for three times of crushing, and the discharge enters the secondary screening 2 sets of 2MF2470 vibrating screens (the upper sieve of the vibrating screen is 31.5mm*31.5mm, and the lower is 5mm*5mm). The materials above 31.5mm in the upper layer enter the semi-finished product buffer storage to form a closed loop. The materials of 0-5mm in the bottom layer are sent to the finished ridge for stacking. The 5-31.5mm material in the middle layer is sent to the third screening (2 sets of 2MF2470 vibrating screens, the upper sieve aperture is 20mm*20mm, the lower layer is 10mm*10mm) for screening, and the sieving is divided into 20-31.5mm, 10mm-20mm, 5mm-10mm finished products Piled up.

Advantages of the production line:

1. The design of the plant area is standardized, with compact structure and easy site layout; the equipment is centralized and connected in parallel, which is convenient for maintenance;

2. Set up 4 ridges for finished products, with a large reserve of finished products;

3. The plant occupies a small area, which is convenient for the construction of green mines;

4. Equipped with automatic loading system to save labor and mechanical loss.
