It is important to note that the products of the two classes of crusher (low-speed and high-speed) cannot be compared directly upon the basis of their respective open-side and close- side settings. Nor, can the products of any two types in the high-speed class be compared upon this basis, unless it is known that their speeds, throws, and general shape of crushing chamber are similar.

The size of a jaw crusher is usually described by the gape and the width, expressed as gape × width. The common crusher types, sizes and their performance are summarised in Table 4.1.Currently, the dimensions of the largest Blake-type jaw crusher in use are

Essentially, the gyratory crusher consists of a heavy cast-iron, or steel, frame which includes in its lower part an actuating mechanism (eccentric and driving gears), and in its upper part a cone-shaped crushing chamber, lined with wear-resisting plates (concaves).Spanning the crushing chamber across its top is a steady-rest (spider), containing a machined journal which fixes the position of

one crushing zone. The speed at which the crusher would have the theoretical maximum capacity is known as the critical speed. High speed cone crushers are operated at super-critical speed, in the portion of the speed vs capacity curve where the capacity is dropping as the speed is increasing (see Figure 1). Note that the shape and

2015-06-20· If 75 percent of critical speed is considered desirable for efficient grinding in a 2.4 meter (8 foot) diameter mill, then the same will be true for a 5.0 meter (15½ foot) diameter mill. At least

The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison, rod mills would operate between 50% to 95% of the critical speed. The faster the mill speed, the greater the wear on the rods and liners. So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the

In Mineral Processing Design and Operations (Second Edition), 2016. 5.1 Introduction. Gyratory crushers were invented by Charles Brown in 1877 and developed by Gates around 1881 and were referred to as a Gates crusher [1].The smaller form is described as a cone crusher. The larger crushers are normally known as primary crushers as they are designed to receive run-on-mine (ROM) rocks directly

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.

The percent of critical speed is the ratio (expressed as a percentage) of the actual mill speed and the Theoretical Critical Speed of that mill. Design, Construction and Performance Analysis of a 5 KgLaboratory (85 microns) is less than P80 (100 microns) used in the design of the ball mill. Keywords: laboratory ball mill, bond's equation, shaft
