the manufacture of Portland cement. Gypsum and Pozzolana are going to be used for final cement grinding with clinker produced from kiln. A few meters away from the quarry there is one FLS hammer crusher which can crush 550ton/hour. The crusher reduces 85% of the rock lumps from a 2meter size down to less than 25mm. 2. Raw Material Preparation
Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is employed.
Q = 643.3 m3/hr Product: PPC Cement with 275t/h output & 360 m2/kg Blaine As per the chute design formula, the minimum free area of chute should be calculated on the basis of Velocity 1 m/sec and Chute being 25% full for powdery material [50% in case of lumpy material] A = Q x 100 / (3600 x V x F) in m2 = 643.3 x 100 / (3600 x 1 x 25) A = 0.715 ...

Closed Circuit is defi ned as a combination of a crusher and one or more screens were all or parts of the material will pass the crusher. Over sized material will then be re-circulated to somewhere before the crusher and thereby fed to the crusher again to be re-crushed. Parts of the rock material will thereby pass the crusher more then once.
The following example demonstrates a method of selecting the components of an aggregate plant. Good component efficiency and part performance pre-evaluation is essential to a solid design. The aggregate production requires the consideration of several crushers, feeders and screens. This is not intended to be a typical situation, though it …
