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.
In this study an analytical perspective is used to develop a fundamental model of a jaw crusher. Previously jaw crushers were modelled in regard to certain aspects for example energy.
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.
Crusher wear studies by Columbia Steel take the guesswork out of cone liner jaw plate and gyratory wear part choices benefiting your operation with better production and less downtime. Crusher OEMs generally offer a limited choice of wear part designs and these are usually based on average conditions.
Jan 17 2016 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 is possible when all conditions are favourable to.

Feb 16 2018 Safety on a crusher starts with the person feeding the plant. The person feeding the plant needs to be trained on best practices specific to the crusher they are working with. An operator may have years of experience operating and loading a cone crusher but that doesnt translate into experience loading and operating a jaw crusher.
In crushers like C105 and C3055 the jaw die design on the ends is different. The lock-ing wedges on these crushers are located behind the jaw dies rather than at the top of the jaw die. Jaw dies can be allowed to wear until the thickness is 60 to 65 mm thick or the teeth are worn flat. On other crushers the ends of the jaw dies are much thinner.
All aspects of the QMS jaw crusher have been specifically assessed with attention to even the smallest of details resulting in the highest possible reliability and functionality. All QMS jaw crushers are 100 manufactured and built in-house at QMS.
