For the problem outlined, this formula sets up as follows: T= 100/ (1-0.3) = 142.9 tons. Thus, whereas we are dealing with only 100 tons of original feed, we must for the closed-circuit operation, set up crushing capacity for at least 142.9 tons, or 42.9% circulating load.

This one involves both SECONDARY and TERTIARY crushing. This circuit is employed where either the tonnage or the work index of the ore is high enough to require that the crushing be done in stages. Again the ore will come from a Primary crusher and be scalped. The coarse material will be crushed by the secondary crusher.

It is important to match the CSS of the crusher to the top size of the product to be produced. If the circuit is being closed at 25mm (1") to produce a 25mm minus product, the crusher should be set at, near or slightly below 25mm. {{image3-a:l-w:640}} Impact crushers. An impact crusher uses mass and velocity to break down feed material.

A horizontal shaft impactor uses hammers to do the job, and is therefore better for softer materials such as limestone and phosphate. Start selling today. Browse new and used Crushing Plants For Sale near you. Find Crushing Plants by FABO, , , Powerscreen, and more on MyLittleSalesman.

Figure 6.4 is a typical set-up where ores crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in an open circuit followed by finer size reduction in a closed circuit by a roll crusher. Such circuits are chosen as the feed size to standard roll crushers normally does not exceed 50 mm.

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:
