13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of (−) 1.5 m size. These large-sized ores are reduced at the primary crushing stage for an output product dimension of 10–20 cm. The common primary crushers are of jaw and gyratory types.

Gyratory Crusher. A gyratory crusher consists of a concave surface and a conical head constructed from heavy steel casting. It works by using a mantle that gyrates within a concave bowl. ... Jaw Crusher. A jaw crusher also uses compressive force and the materials are allowed into a gap at the top of the equipment between two jaws. One of …

The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It …

Presently, belt life is considered to be unlimited, with minimal, largely routine, maintenance. Crushing and conveying cost is presently $. 15/ton ($ 1. 93/ton/total mining cost) as compared to $ 24/ton haulage cost alone prior to 1968. Feeder-breakers run untended, although a mechanic visits each one twice per shift.

Jaw crushers, cone crushers, gyratory crushers and roll crushers all operate on the compression principle. Impact crushers utilize the impact principle, while hammermill crushers follow the principle of …

The family of primary crushers include: Gyratory Crushers Jaw Crushers Impact Crushers; Typical rules for primary crusher selection: Rule 1: Always use a jaw crusher if you can due to lower costs. Rule 2: For low capacity applications, use jaw crusher and hydraulic hammer for oversize.

Gyratory crushers have larger capacity because the action is continuous, as compared to a similar size jaw crusher. The capacity is similar to that of a jaw crusher with the same …

Many small process plants consisted of one crusher, either jaw or gyratory rock crushers, one elevator and one screen. Recrushing, if done, was taken care of by the same machine handling the primary break. The single crusher, when of the gyratory type, might be any size from the No. 2 (6″ opening) to the No. 6 with 12-in. opening.

A robustly designed one-piece main shaft and reinforced shells are made for tough use. The one-piece spherical spider bearing offers at least 5 times longer wear life than than previous ...

Jaw crushers operate on a simple principle. A jaw crusher uses compressive force for breaking the material. This mechanical pressure is achieved by the …

Jaw gyratory crushers – design and operating principle Technical data The main characteristic of jaw gyratory crushers is their enlarged feed opening which is located on one side of the crusher only. It is normally serrated and, to- gether with the upper part of the mantle, it forms the initial crushing zone. The

jaw and gyratory crushers. Manufacturers redesigned their gyratories to reduce the feed opening, decrease the closed-side setting, and in- ... The gyratory crusher has been built in three types known respec- tively as the suspended-spindle, the supported-spindle and the fixed- spindle type. The second type, with the hydraulic piston as the sup

Gyratory crusher can work continuously, has high productivity and crushing ratio( up to 6-9.5), working performance is very stable, light vibration. Jaw crusher cannot work continuously, leading to …

Gyratory crushers often are built into a cavity in the ground to aid in the loading process, as large haul trucks can access the hopper directly. JAW CRUSHER. Jaw crushers are also compression crushers that allow stone into an opening at the top of the crusher, between two jaws. One jaw is stationary while the other is moveable.

Jaw crushers are generally defined by their opening size. For example, a 900x650 mm crusher refers to a crusher with an inlet measuring 900 mm by 650 mm. The main parts and main technical parameters of a jaw crusher are presented below. 1. Feed Chute 2. Drive Flywheel 3. V-belts 4. Electric motor

These machines come in three main types, jaw crusher, cone and gyratory crusher, and impact crusher. Jaw crushers, occasionally referred to as "toggle crushers," are the most common type …

Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32" from jaw die to jaw die at the top opening or gape opening and 54" across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.

1. The difference between gyratory crusher and jaw crusher: The gyratory crusher can perform continuous crushing operations, so productivity is relatively high. In …

The gyratory crusher can, just like a jaw crusher, accept boulder sizes close to 1.5 m (for the largest equipment). – This crusher can handle products with a Mohs hardness that is not necessarily less than 5. – As is the case for jaw crushers, there is not any mutual sliding on grinding surfaces, but simply rolling of the nut on concaves.

2 Gyratory Crushers 8 3 Jaw Crushers 12 4 Cone Crushers 20 5 Roll Crushers 23 6 Low Speed Sizers 26 7 Horizontal Shaft Impactors 29 ... many times, rotary breakers are used as primary crushers and ring granulators are used as secondary crushers. Information on construction and working of various crushers is given in the following chapters.

A scalping unit is frequently used between the feeder and the primary crusher to remove from the feed material that is smaller than the setting of the crusher. It may be a grid, grate, or screen, and it may be stationary or it may víbrate. Raw material removed from the feed is sent to finish screens and reduction crushers.

the crusher and scalp out fi nes. Primary gyratory crushers – ideally suited to all high-capacity primary hard rock crushing applications. Jaw crushers – we have more installed jaw crushers than anyone in the world. The lead-ing choice due to their high reduction ratio and heavy duty design. Cone crushers – capacities available to suit all

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°.

Gyratory breakers may be used for crushing all kinds of material for which a jaw breaker is considered suitable, with one or two rare exceptions. So far as the gradation of the product is concerned, jaw and gyratory crushers are similar, particularly when corrugated mantles and concaves are fitted in the latter machines.
