What is the eccentric throw? — Sandvik Mining and Rock Technology

The eccentric throw is one of the most important parameters in defining the job that your cone crusher does. The mantle in a cone crusher spins in conical pendulum motion. That means it doesn’t stay in the center of the chamber – it sweeps around moving closer and further away from the concave. This is what creates the crushing action.

Variable throw eccentric cone crusher and method for ...

Typically, the throw of a cone crusher is set by the degree of eccentricity of the eccentric member which transforms the rotational motion of a drive member into the gyrating motion of the head and mantle. It is possible, however, to vary the throw of the cone crusher.

CH840i Cone crusher — Sandvik Mining and Rock Technology

Each crusher has a hydraulically supported main shaft which is supported at both ends. With a robust design, adjustable eccentric throw, a constant intake opening, high performance can be achieved by proper selection of a Sandvik OEM crushing chamber. The CH840i brings you a revolution in intelligent crushing.

Symons Cone Crusher - 911Metallurgist

One of the first cone crushers had a direct drive vertical motor mounted above the spider with the drive shaft passing through the hollow bored main shaft. With relatively high speeds of 480 to 580 rpm and small eccentric throw the machine produced a uniform produce with minimum fines.

Cone Crushers for Sale

The reason why the Hydrocone crusher will produce such a uniform, cubical product is that it has a small eccentric throw with respect to the crusher setting. This means a smaller effective ratio of reduction during each crushing stroke, and therefore, the production of fewer fines and slivers.

Gyratory and Cone Crusher - ScienceDirect

Jan 01, 2016 · A secondary crusher (size 16–50) with approximate feed opening of 41 cm × 40 cm had an eccentric throw of 1.9 cm. Gyrating at 225 rpm it crushed limestone with an open setting of 3.8 cm. Calculate the percent change of power required when the open setting was altered to 9.0 cm.

Cone Crushers | McLanahan

Spiral bevel gears provide the turning force to the eccentric. The spiral gear is mounted on a sturdy countershaft of the Cone Crusher, which rides in bronze bushings. The gears are precision cut for quiet operation. Misalignment problems are eliminated. The MSP Cone Crusher features one of the largest volume displacements by a crusher head.

Geometric analysis of cone crusher liner shape: Geometric ...

Jan 01, 2021 · The eccentric throw (Fig. 19a) increases nearly linearly and strongly until contact is made between the liners. This means that the eccentric throw is not a useful quasi-invariant from a design perspective for the cone crusher as it changes strongly with the eccentric angle. Fig. 19b shows the variation of LRR with the eccentric angle. LRR is ...

eccentric throw on a cone crusher

CONE CRUSHER. A cone crusher is similar in operation to a gyratory crusher, with less steepness in the crushing chamber and more of a parallel zone between crushing zones.

Cone Crusher Configuration – How Setup Your Crusher For ...

So, comparing a crusher running on the smallest throw with a crusher running on the biggest throw you can except the crusher with the biggest throw to produce better shaped product and a higher percentage of fines. Figure 9. Crusher operated with two different eccentric throws, smallest 16 mm and biggest 44 mm.

Buyer's Guide: Crushers - Equipment & Contracting

The eccentric throw range is related to how much the crusher’s mantle veers away from its axis. This determines the rate the material will fall through the chamber. Crushers with a high eccentric thrown will allow particles to fall farther in a single revolution.

Investigation of High Speed Cone Crushing Using Laboratory ...

In a cone crusher the feed material is compressed between the walls of the mantle and concave. The mantle is eccentrically displaced allowing for a nutating motion with an amplitude corresponding to the eccentric throw. The smallest distance between the mantle and concave, termed the Close Side Setting

The Importance of Choke Feeding a Cone Crusher - Pilot Crushtec

Changes to the CSS (close side setting) as well as the crusher eccentric throw affect the volume of material in the crushing chamber. Unique to Sandvik cones, is that the crusher eccentric throw can be adjusted without replacement of any internal parts.

Cedarapids Launches New CRC320 Cone Crusher Plant

May 28, 2020 · The TG320 is a 300 hp bushing cone with large feed size that can be easily and efficiently set up to perform and deliver the best cost per ton cubicle product by selecting the optimum crushing cavity and eccentric throw to suit the application requirements.

cs cone crusher eccentric

Symons Cone Crusher - 911Metallurgist. The cavity design eccentric (head) speed and throw of the hydrocone are equivalent to the Symons Cone Crushers. The need for increased crushing capacity within the volume or space occupied by existing crushers was one of the objectives in the design of the cone crusher.

WO2000021673A1 - Variable throw eccentric cone crusher and ...

A variable throw eccentric cone crusher (10). The cone crusher (10) comprises a frame (14), a crusher head (30) supported on the frame (14) for gyration about a first axis, a bowl (54) supported on the frame (14) in spaced relation to the crusher head (30), and a mechanism on the frame (14) for varying the eccentricity of the gyration of the crusher head (30).

Blackhawk Cone Crusher | Sepro Mineral Systems

The most efficient cone crusher on the market. The Sepro Blackhawk 100 Cone Crusher is a modern, hydraulically operated cone crusher designed to be simple, rugged and effective for heavy duty mining and aggregate applications. The combination of the speed and eccentric throw of the crusher provides fine crushing capability and high capacity in ...

Raptor® Cone Crusher best in class | FLSmidth

Because of its large head diameter of 1.5 m (59.06 inches) and ideal eccentric motion, the Raptor 500 cone crusher can accept feed that is up to 25 percent larger than can be accepted by competitive cones with less throw or similar head diameter, while producing more material of desired cubicity and gradation.
