    What Is Primary Secondary And Tertiary Crushing

    Primary crushing is the first stage of material reduction and can sometimes be the only stage needed to generate the desired product for a job. Depending on the setup, primary crushing will take the larger material that has been blasted, excavated, or reclaimed and process it through an impactor, jaw, or gyratory crusher to generate a range of product sizes.

    The gyratory crushers crush to reduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction hence, the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in size takes place. Here, the maximum reduction ratio is about 81.

    Any fluctuation in pressure means that the optimal force will not be delivered consistently so, of course, crusher performance declines. These are the two main causes of sub-optimal crushing performance, but losses in the reduction ratio can also be caused by selecting the wrong mantle or by having a poor chamber profile or design.
