Borgers Jaw crushers Typical solution is to start with manganese steel linings to run the process up to target capacity and gradation. The maximizing of chamber life takes place when the process is stable. Several low alloys of quenched and tempered steel as well as tool steel and chromium iron are available for specific applications. Jaw Plates for Jaw Crushers The crushing chamber is composed of a Stationary /Fixed Jaw (frame side) and a Movable/ Swing Jaw (pittman side), and they may be one piece or more, depending on the crusher size and design. Its longitudinal profiles are designed taking into account the best combination of the nip angle, differentiated wear profiles between stationary/swing, therefore maximizing the crusher productivity, as well as providing the best exploitation of the wear material. There is a wide variety of transversal tooth profiles to ensure your productivity and operational costs to be optimized for each application type. It is important to have similar transversal profiles for the used pairs (stationary and swing jaws) so that we may obtain the correct combination to avoid any harmful effort to the equipment, as well as to achieve the best product quality. Following, you many find charts of the main transversal profiles and their corresponding features. C Crusher product Line Standard Profile – Suitable for both rock and gravel crushing, – Well balanced wear life, power requirements and crushing stresses, – Typical factory installation       Recycling Profile – Suitable for concrete crushing, – Fine material flows easily through the cavity along the large grooves.         Quarry Profile – Suitable for blasted rock crushing in quarries, – The flat teeth have a better performance with abrasive materials (more wearable tooth material), – Causes high stresses and increases power requirements.           Super Teeth Profile – Suitable for general use and especially a good choice for gravel crushing, – Large mass and special design of the teeth provide long wear life and make fine material flow down through the cavity along the grooves without wearing the teeth.   Note: Not all profiles are available for all crusher models.
