A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
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.

Double row, spherical roller bearings used on all models.
shape, increased reduction ratio, higher throughput and a reduced wear factor. The 1200TC features a 440Hp (328Kw) 6 cyclinder engine, a 1200mm wide cone crusher unit with hydraulic closed side setting ''on the fly'' and metal detection system on feed belt to protect from uncrushables.
Sep 19, 2012 · Jaw crushers offer reduction ratios of up to about 6:1, while cone crushers can reduce material size up to a maximum of 8:1 ratio. The finer the crushing, the smaller the reduction ratio. As a basic rule, jaw crushers are the primary crusher taking the mined aggregate and reducing it to a size that a cone crusher can accept.
A Cone Crusher will deliver a 4:1 to 6:1 reduction ratio. As we set the closed side setting tighter to create a finer output, we also reduce the volume or throughput capacity of the machine. Generally speaking, multiplying the closed side setting by two is a good guide to the top size
All crushers have a limited reduction ratio m eaning that size reduction will take place in stages. 3.2 Operation stages: The operating stages in minerals process ing have remained the same for
The operation is similar to the standard cone crushers, except that the size reduction is caused more by attrition than by impact . The reduction ratio is around 8:1 and as the product size is relatively small the feed size is limited to less than 50 mm with a nip angle between 25° and 30°. The Gyradisc crushers have head diameters from
