why choke fed cone crusher

A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer's data indicated that the nearest size of gyratory crusher would be 1370 mm × 1880 mm with a cone angle of 18°.

The product from crushers of the standard gyratory type, or the older reduction types, as well as all types of jaw crushers, will be affected to some extent by the method of feeding; that is, whether the machine is choke-fed or not. The choke-fed crusher produces more fines, due to attritional grinding between particles in the crowded …

The choke level is a function of the liner design, eccentric speed, stroke and CSS. It has been reported that cone crushers work best when choke fed (Bearman and Briggs, 1998, Jacobson et al., 2010, Santos et al., 2020) and that operating under these conditions extends the durability of both the liners and the equipment. 2.6.4.

For instance, a jaw crusher with a choke-fed chamber performs best and maximizes production capacity while producing uniformly broken particles. As such, a choke-fed chamber increases your crusher capacity and efficiency. ... and cone crusher are popular secondary crushers. Still, note that you may use a jaw crusher as a secondary crusher …

Its unique crushing action provides excellent capacity, high reduction, and good product cubicity for the production of high-quality aggregate and sub-base materials. A level probe over the feed ring regulates the feed belt to ensure the cone chamber is choke fed, essential for maximum reduction, manganese life, and optimal product shape.

Type of Crusher: Different types of crushers are used for crushing stones, such as jaw crushers, cone crushers, impact crushers, and more. ... Why choke fed cone crusher? Oct 16, 2023

It is critical that a cone-type crusher be choke fed to produce the best product shape and quality. It is not as important in a jaw, as material is not generally stockpiled after the jaw. Because the cone is …

The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the …

These crushers are always operated in choke feed conditions. ... The cone crusher (Fig. 13.12) is very similar to the gyratory type, except that it has a much shorter spindle with a larger-diameter crushing surface relative to its vertical dimension. The spindle is not suspended as in the gyratory crusher.

Cone crushers are specialized machines used to crush and grind rocks and ores into smaller particles. ... Why choke fed cone crusher? Oct 16, 2023

• Stroke adjustment enables choke fed condition for different feed rates. Choke feed maximizes capacity, shape and reduction ratio. • Short stroke lowers power draw and piston pressure and helps the crusher to reach tighter CSS. Typically best product shape and size fraction share is achieved around the CSS.

Cone Crusher Function. A cone crusher has an annular crushing chamber. The CSS runs around the chamber so the action is basically rotational. Raw material enters the chamber on the OSS and is crushed one. h alf revol uti on l at er b y th e CSS. This cycle takes place in most cone crushers 5 to 6 times per second.

The optimal arrangement for a cone crusher is to choke feed it with a non-segregated feed. This will help the crusher run more smoothly by lowering both power and pressure …

A cone crusher must always be choke-fed in order to maintain the highest levels of capacity, gradation, and cubical output. A surge bin (or hopper) and feeder that are placed before the crusher work best to maintain a choke-feed to the cone crusher. Without a hopper and feeder, it is nearly impossible to achieve choke-feeding.

Most cone crushers have a feed opening size of 5-14", so material that's larger than the maximum size allowable will need a first stage of crushing before they can be fed into a cone crusher. Final Product Isn't Uniform. Cone crushers do an excellent job of providing finished material that's relatively homogenous.
