The capacity of the single-roll crushers is a function of the roll gap, the roll length, and the speed, and ranges from about 30 tons/h (27 metric tons/h) for a 24-inch-long (61 cm) roll crushing to inch (2 cm), up to approximately 1500 tons/h (1360 metric tons/h) for an 84-inch-long (213 cm) roll crushing to pass 10 inches (25 cm).
Choosing between a single roll crusher and double roll crusher depends upon the type of feed material, feed size, product size desired, and consistency of both feed and product. Both single and double roll crushers operate most efficiently with dry, friable materials.
Rolls and the maximum Roll Gap These dimensions are design decisions which depend on desired input particle size, the feed rate and maximum output particle size. The specification for is 120mm, width, W, of each roll is 150mm, and the maximum roll gap, l, is 5mm. 2.1.3 Maximum Size of the Particle that can be Fed into the Roll Crusher

Dec 16, 2015 The maximum feed size for a jaw crusher should be about 85% of the gape. Source Arthur Taggart The combination of a jaw crusher and a scalping grizzly will have 15% more capacity than a stand-alone jaw crusher. Source Ron Casson As a rule, scalping grizzlies are rarely used anymore for (large) primary crushers.
It can reduce most rock-like materials of 0.5in (13mm) feed size to minus No. 10 (2mm) at a capacity up to 8,000lbs (3,629kg) per hour. Operates at 60Hz.

Roll Crusher Roll crusher consists of two horizontally mounted rigid cylinders always moving in opposite direction but towards each other and downward. The ore particles to be crushed and nipped are pulled inward through the rolls by friction.
Factors influencing the energy consumed by crushers 1) Size of feed, 2) Size of product, 3) Capacity of machine, 4) Properties of rock or ore, 5) Percentage of idling time (the time when the crusher is not in use) etc. Roll Crusher Not widely used also

Toothed roll crushers are much more versatile then smooth roll crusher, within the limitation that they cannot handle very hard solids. Operated by compression, impact and shear. The particle size feed to these machines may be given as great as 500 mm and the capacity is 500tons/hr. Crushers Toothed Roll Crushers
Maximum feed size varies with each model, but is generally limited to around 600900mm. The output gradation of the primary HSI crusher is generally coarser than the primary breaker due to the lack of expansion above the rotor, which also affects the capacity.

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 81. Feed ROM up to 1.5 m. Product -300mm (for transport) to -200mm (for SAG mill) Feed Rate
May 06, 2020 The new hybrid models of impact crusher are engineered for maximum feed size, target output size, and total capacity. The newer models are capable of producing construction-grade aggregate, artificial sand and stone materials, run of mine material, especially for the secondary and tertiary crushing stages.
As a rule, Jaw Crushers have a 61 or 81 ratio for crushing material. Still using the 32 x 54 Jaw Crusher example, the top size of the feed entering the crushing chamber has to follow the F80 rule that 80% of the top size feed material is smaller than the gape opening.
A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 61 reduction ratio. Thus, with a 34 closed side setting, the maximum feed would be 6 x 34 or 4.5 inches. Reduction ratios of 81 may be possible in certain coarse crushing applications.
