Jaw Breakers is the oldest and widely used crusher type, which compresses the all-in material obtained from the riverbeds and stone between a fixed and movable two jaws. Movable jaw realizing the crush action is activated through eccentric drive bearing and hanged over the body, supported to the body of the breaker via security plate.

Movable jaw moves by drawing an ellipse on the feeding end close to a cycle and draws a narrow ellipse on the flow end close to straight line. This provides the material to be grabbed on the upper end and results in release through the speed gained on the flow end thus accordingly results in the material flow. 
Generally it is impossible to acquire the desired material dimension through a single crusher. Jawbreakers can be used as the primary crusher breaking the material roughly or they may be used as the secondary crusher to refine the material. Feeding space of the secondary jaw crushers is narrower than that of primary crushers. Determining factor in the selection of the crusher is material to be fed, desired dimension of the material, and hourly production capacity. Related graphic and tables are given in the next page. Feeding space between the jaws should be selected larger than the maximum material to be fed. Accordingly blockage to be caused by bulk stones will be eliminated, and the capacity will increase as a result of constant feeding.

In order to provide desired average capacity, crusher should be selected above the theoretical values by taking problems that can stem from feeding or other issues and loss into consideration.

FEEDING END SPACE (Al) Horizontal distance within the fixed and movable jaw plates between upper gear point of one and corresponding lower gear of the other.
OUTPUT FLOW SPACE (A2) It is the distance between the jaw plates on the far end of the crushing area measured in the same way as Al space. During this measurement jaw space should be in the most closed position.
GRAB ANGLE It is the angle between the fixed and movable jaw plates. If it is above a specific level material will be grabed in a difficult way, it will result in rebound and crushing capacity will decrease.

CRUSHER BODY(l), Complete welded manufacture from the thick sheets.
MOVABLE JAW(8), steel cast providing high durability. Beds of the bearings are processed sensitively in such a way to have the same axis. JAW PLATES, manganese alloy, corrosion durable special steel cast. Back sides of the plates processed and placed completed on movable and fixed jaw and the body. In Ç90-65, Çl 1 -85 and Çl 3-10 models fixed-moving jaw plates have two symmetric parts. Early corrosion occurs in the ends close to the flow end can be eliminated by reversing the jaws and life span can be prolonged up to 4 times.
SIDE PRIMING PLATES (12), manufactures in parts and can easily be replaced if corroded.
ECCENTRIC BEARING (14), processed from special alloy (Mi. Cr.Nİ.Mo.) pounded steel material. Dimensions of the bearing are adjusted to the adequate size and thus strength is provided.
BEDDING CONDITION (15), crushers are equipped with movable bobbin beddings to provide self axis in case of axis diversion that may occur during the force revealed during breaking process. Beddings are protected with labyrinths with small gap to eliminate entry of the dust and exit of the grease oil. Crusting bearing beds are made up of lower part welded to body sheet and upper cap mounted with a screw.
SECURITY PLATE BEDDINGS (7), made up of special steel cast and operating parts are processed.
SECURITY PLATE (6), made up of pig cast and lower plate ends are rolled through stones, accordingly it displays rolling instead of sliding. Therefore special oiling process in not required.
FLY WHEEL (13), it is heavy enough to provide correct operation even when the crusher is overloaded and made up of pig iron. On the opposite end of the flywheel there is driving frame transferring power from the engine through V belts.
CRUSHER OUTPUT ADKUSTMENTS (3), jaw space should be changed in order to adjust the dimensions of the material flowing from the crusher and increase the capacity Hydraulic jaw adjustment system provides convenience in adjusting the jaw to the desired level. Piston movement pushes the adjustment block and security plate and enables moving jaw on the pitman to reach the fixed jaw. Crushing process can only be efficiently performed at specific grab level thus so jaw output adjustment can be performed within specific limits depending on the breaker type. Output adjustment is performed through screws excluding Ç90-65, Ç11 -85 and Ç13-10 mechanisms In Ç90-65, Ç11-85, Ç13-10 jawbreakers automated central grease oiling system is available.

In Table1 hourly production capacities of several jaw breakers are given according to their jaw space. Curves of the implemented crusher type is intersected by drawing a horizontal line on the flow end, vertical lines are drawn from these points minimum and maximum capacity of the breakers are determined. For instance, production capacity of Ç90-65 jaw breaker at 120 mm jaw space is 90-130 ton/hours. In table 2 product dimension distribution is given depending on the flow end space. Curve selected depending on the flow end space is intersected through a vertical line. If it is horizontally moved to the left from this point amount of the material smaller than that product, when moved to the right g amount of the greater material will be determined.

For instance at 200 mm flow end space amount of the material smaller than 150 mm (0-150 mm) is approximately 47 %, amount of larger material (+150 mm) is 53 %. All values given in Table 1 and 2 are medium hard, 1.6 ton/m3 pile density limestone, and dents of the size and feeding type of the material fed. Please consult to TEK-EL MAKİNA for other materials.
