You cannot exceed the maximum allowable feed size for the cone crusher model. The feed size will depend on factors such as the closed side setting, eccentric throw, and head diameter. Exceeding the max feed size will lead to premature crusher failure. Use the minimum CSS and throw to determine the largest feed material allowable.

The maximum equivalent feed particle size d A,max can be derived from the following geometric relationship which is obtained from the triangle ABC in Fig. 1: (5) cos α 2 = R W + s 2 R W + d A 2 With the radius R W of the roll, the gap s between the rolls, the particle size d A, the trigonometric relation (6) and R W = D W / 2 with D W as the ...
I have made a number of general remarks regarding the character of product delivered by crushers of various types, and under different conditions of operation. Generalities are of value only if we have some standard to which comparisons may be referred; therefore, we should like to present more specific information on the kind of …
Marcy® Gy-Roll Cone Crushers reduce 10 mm (1/2'') feed to 2mm (10 mesh) final size, depending on material type. They are well suited for medium hard to hard materials, such as aggregate and mineral ores. These crushers are powerful and tough enough for continuous demands of pilot plant or small production applications.
Table 3 shows that the ratio between d100 i.e. Maximum product size and discharge setting is highest for roll crusher. ... View in full-text Get access to 30 million figures
Roll Crushers. Similar to Sizers, Roll Crushers can be used for the primary crushing of soft to medium hard material that can be slightly abrasive, dry, or wet and sticky. They are typically used in heavy mining applications and have a typical ratio of reduction of 4:1. Primary Roll Crushers are available in several designs:
Increase productivity with a revolutionary roll crusher The ERC 22-20 is a revolution in primary crushing that ... hardness UCS, feed particle size distribution, moisture content), the desired product size and the selected machine settings (e.g. gap setting CSS). 2. Height h = maximum dimension between jaw liners and roll liners. 3. Standard ...
The tables also show that for a comparable maximum size of feed and setting, a gyratory crusher has a much greater capacity than a jaw crusher. The gyratory crusher obtains this advantage only at the cost of greater power to drive the crusher. ... Typical Capacities of Twin-Roll Crushers (tons/hr) Crusher Size (in.) Power Required …
Single Roll Crushers. Single Roll Crushers are typically used as primary crushers that provide a crushing ratio of up to 6:1. They crush materials such as ROM coal, mine refuse, shale, slate, gypsum, bauxite, salt, soft shale, etc., while producing minimal fines.Designed with intermeshing roll teeth and a curved crushing plate, they are extremely effective in …
Crusher Feed Size and Roll Diameter. The diagram in Figure #3 shows the method used in calculating maximum feed size for any diameter of rolls; the accompanying table gives …
A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54".
1) Crusher capacity calculated based on a typical run-of-mine feed material with an average raw density 2.8 t/m³ and max. feed size ≤ 80 % of crusher feed opening. Actual values …
The Single Roll Crusher, with its 6:1 ratio of reduction, is ideal for reducing large feed lumps to a medium product size while producing a considerably lower percentage of fines. Products; Solutions. Industries. Aggregates; …
Roll diameters and widths are dictated by the feed size, product size and capacity. The rule of thumb for the Double Roll Crusher's ratio of reduction is 4:1. The simplified design gives these units excellent reliability and requires very little maintenance.
Features of Sledging Roll Crushers. A dumped load of feed experiences vigorous agitation, immediately sifting smaller pieces down into the crushing chamber. ... Maximum feed size for non-friable material should not exceed that which can be nipped, except that breakage of long slabs can and does take place on top of the roll by beam …
