The single-roll crusher has a tip speed of 400-450 ft/min while the 6- x 7-ft teethed roll crusher has a normal, no-load, surfaces speed of just under 3500 ft/min. It can be readily appreciated that this high velocity induces an extremely violent crushing action, in conjunction with the 3- to 4-in. knobs which protrude from the roll surfaces.
The speed of rolls varies from 50 to 300 rev/min. Crushing rolls are secondary crushers accepting feed 12 to 75 mm in size and yielding products -12 mm to about 20 mesh. Roll crusher diagram These machines are characterized by …

Maximum Feed Size [mm] Rotor Size D x W [mm] Weight [kg] HRC 0505 : 200 : 250 x 530 : 225 : 520 x 510 : 3.750 : HRC 0507 ... Roll Crusher operation is based on the principle of continuous pressure generated between two counter-rotating rolls; allowing uninterrupted crushing, in contrast to the intermittent action of jaw crushers. ...
A pair of rolls is to take a feed equivalent to spheres of 3 cm in diameter and crush them to spheres having 1 cm diameter. If the coefficient of friction is 0.29, what would be the diameter of rolls? Calculations: The following formula relates the coefficient of friction (μ), radius of rolls (r), radius of product (d), and radius of feed (R):
Rotor speed: Adjustable. Possible speeds include: 31, 66 and 84 rpm. Housing material: Painted mild steel. Roll shaft material: Sverker 21 steel, hardened to 58 HRC. Particle size (input): 50-300 mm. Particle size (output): 10-60 mm. Material flow: Depends on material and rotor speed.

As the feed moves towards the drive end of the cone crusher, its size decreases (due to the crushing action), and ever smaller pieces move towards the drive end of the crusher. After passing through the crusher, the product -now at a much-reduced size- is discharged through an opening in the bottom shell.
The Essa RC3000 Rolls Crusher is a dependable and sturdy mid-range secondary crusher that has a maximum feed size of 40 mm. It is designed with contra-rotating rolls to produce material with a tight size envelope containing minimum of fines. This gives you consistent quality, accurate size distribution, and very little dust.
Your workers will appreciate the contra-rotating rolls, fitted feed hopper, easily accessible aluminium sample draw, mesh guarding, and dust extraction point. Specifications. Capable in …

When meter fed to produce granulated product with few fines, the roll gap should be only slightly wider than the desired average particle size. Operating the rolls at equal speed helps minimize fines. For maximum size reduction, as when …
Roll teeth are all designed to grab the feed material and reduce it to desired product size with minimum fines; Pre-screen as standard to ensure maximum scalping capability maximizing …
The single roll crusher reduces large size particles in the feed to a medium size while producing a considerably lower percentage of fines than other crushers. ... Capacities shown are based upon standard roll speed crushing material with a bulk density of …
The throughput rate and motor power depend on the feed material, feed size, granulometric composition and required product size. The given data are intended as a guide for medium-hard limestone (fines content of 50% in the feed material) and are based on a crushing ratio of 5:1.
When larger feed sizes require up to a 6:1 ratio of reduction to achieve the final product, a Triple Roll Crusher should be chosen due to the inherent design, which allows the larger feed sizes to be readily grabbed in the large throat opening between the top (primary) roll and crushing plate.
Primary crusher feeds usually fall under the "graded" category, and reduction crusher feeds under the "sized." Graded feeds may or may not have the under-size removed, depending upon the nature of the operation and of the material. Sized feed for reduction crushers is generally a screened feed which has definite maximum and minimum limits.
When selecting the proper Roll Crusher for an application, you must fully consider all the components of the crushing process. There are numerous factors to be considered, such as: Material to be crushed; Feed size; Product size; Ratio of reduction; Capacity; Compressive …

All data should be used as a guide only and are not guaranteed. They depend on the feed material characteristics and the actual crusher configuration. B A D E C 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.
The low speed design also reduces the amount of wear and tear on the crusher. Uniform product size: Tooth roll crushers produce a uniform product size, which is important for many industries, including construction, mining, and chemical processing. The adjustable gap between rolls allows for precise size control, ensuring a consistent product size.
