Terex Cedarapids jaw crushers are known for durable construction, high productivity and as a greater value for investment. And now, the new JS Series jaw crushers are built even more rugged and easy to use. We have taken our jaw crushers to a new level of reliability and convenience. The new quick-change jaw die and quick-adjust
functioning Jaw crusher. Most of these components are discussed below. Moveable jaw stock The moveable jaw stock is the main moving part in a jaw crusher. It forms the moving side of the jaw, while the stationary or fixed jaw forms the other. It achieves its movement through the eccentric movement of the crusher main shaft. It is the back and
Dec 25, 2014 The working principle of the jaw crushers is very simple. Powered by a diesel or gas motor, the jaw crusher brakes materials in a crushing chamber. The materials are pushed inside the chamber from the top opening and when crushed they are released through the bottom opening. The crushing power of the jaw crushers depends on the size of the chamber.
Jun 23, 2021 1. Jaw Crusher. Jaw crusher has the characteristics of simple structure, reliable work, easy manufacture and convenient maintenance. It is the most commonly used coarse crushing equipment in mineral processing. 2. Cone Crusher. The cone crusher can be divided into three types: coarse crushing, medium crushing and fine crushing according to its ...
May 13, 2019 Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor.
The jaw crushers are available in 8 different sizes: BB 50, BB 100, BB 200, BB 300 and the bigger models BB 250, BB 400, BB 500 and BB 600. Throughput and final fineness depend on the crusher type, selected gap width and breaking properties of the sample material. Feed sizes range from 40 mm to 350 mm, depending on the model.
In the Jaw crushers, the material particles are broken down by the compressive and shear strains between the fixed and moving jaws. The grain size of the crushed material is determined by the gap between the jaws in the lower part (the discharge slot) and the physical properties of the material.
From Eqs. (1), (2) and (4), the volumetric capacity of a jaw crusher can be written as: Vh = 60N x w(S+T)/2 DT/[G-(S+T)] (5) at low speeds, and Vh = 60N x w(S+T)/2 450 g/N2 (6) = 2.645 x 105 (S+T/2)/N
When the jaw crusher crushes materials, the force exerted by the crushing board in the crushing chamber on the crushed object is called crushing force. The maximum value of crushing force when full load crushing is called the maximum crushing force. Crushing force is the primary data of strength and stiffness of each part of jaw crusher.
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.
Jan 01, 2019 The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8% weight for both crushing mechanisms.
