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.

In-pit crushing with Lokotrack LT160 the largest mobile

Apr 15, 2014 Only the large rock that needs to be crushed passes through the jaw crusher, which is capable of processing rocks up to one meter in size. In this way, energy isn’t wasted on passing small material through the crusher. Crushed rock is then transported to the fixed, in-pit belt conveyor via two mobile Lokolink conveyors.

Sep 02, 2019 Jaw crushers operate according to the principle of pressure crushing. The raw feed is crushed in the wedge-shaped pit created between the fixed crusher jaw, and the crusher jaw articulated on an eccentric shaft. The feed material is crushed by the elliptic course of movement and transported downwards.

Crusher Wikipedia

A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber.

Ball Screws Kaman Automation, Control & Energy

Ball screws are mechanical devices that convert rotational motion to linear motion with a minimal amount of friction. There are several components to a ball screw including a nut and a screw with helical grooves and balls that roll between the nut, the screw and the grooves, while the screw or nut is rotating. Balls are routed into the ball return system of the nut and travel in a continuous

How to Size and Select Ball Screws: An Engineer's Guide

Aug 24, 2012 Because ball screws are a bearing system, they’ll need some type of lubrication to avoid metal-to-metal contact of the balls in the raceway. While the lubrication choice can be either oil or grease, it’s advisable to avoid solid additives (such as graphite) as they will clog the recirculation system.

Lead screws are available with leads as coarse as 50 millimeters, and as fine as 0.25 millimeters. Finer thread pitches offer increased resolution, but do so at the expense of top speed. The 2 basic types of lead screws are friction screws and ball screws. In a friction screw, the nut operates by sliding friction along the lead screw.
