jaw crusher eccentricity calculated

function of eccentric jaw crusher. jaw crusher eccentricity calculated. Function Of Eccentric Jaw Crusher. Jaw crusher, jaw crusher manufacturers in india, jaw,jaw crusher is consists of many parts, like eccentric draft, frame, large belt wheel mobile jaw crusher, flying wheel, toggle jaw plates, gap adjustment screw and so on the main function of jaw crusher is to crush large rocks into

• What is the eccentric throw? — SRP - SRP — Home

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&rsquo;t stay in the center of the chamber &ndash; it sweeps around moving closer and further away from the concave. This is what creates the crushing action. At a given point on the concave, material is

Sep 15, 2014 Sep 15, 2014 It must be at least 36 in. wide for an 18 x 36 jaw crusher. So a 4-ft by 8-ft screen would be acceptable. The 1-in. screen is a second deck for the 38 tph from the jaw crusher, so the deck correction factor is 0.90 and that screen capacity is 2.1 x 0.9 = 1.89 tph/sq ft. The screen area needed under the jaw crusher is 38/1.89 = 20.1 sq ft

JAW CRUSHER. Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher’s two jaw; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to

Jaw-crusher Construction. Jaw crushers are heavy-duty machines and hence must be robustly constructed. The main frame is often made from cast iron or steel, connected with tie-bolts. It is commonly made in sections so that it can be transported underground for installation. Modern jaw crushers may have a main frame of welded mild steel plate
