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 …

A primary jaw crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. It is used in many industries, including mining, construction, and demolition, to crush materials such as rocks, coal, and ores. A primary jaw crusher consists of two plates, one stationary and one movable, which form a V …

Vibrating Grizzly Feeders reduce the amount of material going into the crusher by scalping out the product size ahead of the crusher. This reduces the size of the primary crusher required. The Vibrating Grizzly Feeder provides a continuous feed rate under a variety of loading and material conditions.

Control the feed rate to ensure the crusher is not overloaded or underloaded. Both situations can result in decreased efficiency.

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 overarching principle guiding jaw crushers is a compression action. A V-shaped alignment houses the fixed jaw, serving as the immovable surface that facilitates the initial breakage. Simultaneously, the movable jaw, in a swinging motion, exerts force on the incoming material, compelling it against the unyielding surface of the fixed jaw.

Converts the rotation of the drive motor to the reciprocating motion of the swing jaw. Made from high-strength steel; positioned to create an angle for effective crushing action. Provides support to the bottom of the movable jaw. Acts as a safety device. Breaks under extreme load, protecting the crusher from damage.

The entire fleet of crushers operated and hired out by K&B Crushers is modern, immaculately maintained, and always ready to go. At K&B Crushers, we have a variety of crusher sizes and work rates, ranging from 60 to 90 tonnes per hour. We have crusher types suited to different materials, processes and situations. Read on to find out more.

Jaw crushers are typically used as primary crushers because they can take large and variable sized feed material, so the original feed won't have to be blasted down to a fine size. Powerscreen jaws are designed to be significantly more reliable and have lower wear rates, maximizing production and minimizing wear parts.

Feed Opening: 32x55" / 820x1400 mm: CSS Range: 3.5-9 ... The JS Series jaw crushers are built even more rugged and are easier to use. We have taken our jaw crushers to a new level of reliability and convenience. Learn More about JS4552;

Tons per hour rate needing to be crushed Desired size of discharge material needed Operating hours per day. F100 is the maximum gape opening on a Jaw Crusher. F80 is the feed size to the Jaw Crusher, calculated by taking 80 times the gape opening divided by 100. P80 is the percent passing the closed side setting in tph.

Jaw Crushers and Gyratories do not like excessive fines in the feed, so pre-screening with a Vibrating Grizzly Feeder, Wobbler Feeder or scalping screen of some sort is a must. Jaw Crushers and Gyratory Crushers tend to create fines, so they lend themselves well to applications such as gold where the valuable material is located …

It is the heaviest jaw in the industry. This 44" x 27" hydraulic jaw doesn't cut corners so that you can feed bigger pieces. A 10% deeper jaw box gives you more crushing action. Don't Get Stuck. Reverse Crushing Keeps You Crushing. Crush difficult materials or unblock your crusher with ease.

That is why it needs to be monitored throughout the crusher's lifecycle. As excessive wear can cause a 10–20% reduction in production, it is important to find the optimal time for the jaw turn or change in terms of cost and benefit.
