The difference between the ordinary jaw break and the European version of the jaw break, 6 aspects of comparison make you clear!
Common jaw break and European jaw break belong to a kind of compound pendulum jaw break, the former was developed earlier, in the domestic market, because of its simple structure, relatively low price and widely used. The latter is popular because of easy operation and maintenance, high efficiency, energy saving and environmental protection. Today we’re going to focus on the structural differences.
1, crushing cavity shape ordinary jaw: half V-shaped crushing chamber/European jaw: V-shaped crushing chamber.
The V-shaped cavity structure makes the actual inlet width consistent with the nominal inlet width, and it is easier to discharge the material, relatively easy to block the material phenomenon, easy to jump, deeper crushing chamber, no dead zone, and higher crushing efficiency.
2, lubrication device common jaw: manual lubrication/European jaw: concentrated hydraulic lubrication.
The centralized hydraulic lubrication device is the standard configuration of the European version of the jaw break, which can make the bearing lubrication more convenient and efficient.
3, adjustment mode Ordinary jaw break: gasket adjustment/European jaw break: wedge adjustment.
A group of gaskets of equal thickness are placed between the adjusting seat and the rear wall of the frame, and the discharge port of the crusher is reduced or increased by increasing or reducing the number of gasket layers. This method can be multi-stage adjustment, the machine structure is relatively compact, reduce the weight of the equipment, but it must be stopped when adjusting.
The European version of the jaw break adopts wedge adjustment, and realizes the adjustment of the crusher discharge port by means of the relative movement of the two wedges between the adjustment seat and the rear wall of the frame. The front wedge can move forward and backward, and is integrated with the bracket to form the adjusting seat; The rear wedge is a adjusting wedge, which can move up and down, and the bevel of the two wedges is inclined to fit, and the size of the discharge port is adjusted by the screw to move the rear wedge up and down.
This method can achieve stepless adjustment, easy adjustment, save time, no need to stop, simple, safe, convenient, intelligent, high efficiency.
4. Fixing method of bearing seat
Common jaw break: welding, the bearing seat and the frame are welded, and the service life is short.
The whole cast steel structure of the bolt and bearing seat is linked with the bolt of the frame to ensure the complete cooperation of the two, which greatly enhances the radial strength of the bearing seat and extends the service life.
5, jaw plate structure for large jaw breaks (such as 900*1200 and above), the movable jaw plate is divided into three pieces, and the jaw plate of small and medium-sized jaw breaks usually only one piece. The size of the jaw plate, the middle one is smaller, the upper and lower two are larger, and there is also a wedge on it, which is called a fixed wedge or fixed iron. The jaw plate is bolted to the middle jaw plate and the press iron. For common jaw plates and European jaw plates, the integral or segmented jaw plates can be selectively used according to the size of the equipment model.
Advantages of the three-stage jaw plate:
1) If the large broken jaw plate is a whole block, it is large and heavy, and it is relatively convenient to combine and install it into three sections;
2) The jaw plate is divided into three sections, which is relatively convenient when disassembling;
3) Key benefits: The design of the three-segment jaw plate is smaller in the middle and the two ends are the same size. If the bottom end of the jaw plate wear is more serious, you can adjust the position with the upper end of the jaw plate, continue to use, save costs.
6. Shape of jaw plate and guard plate
Common jaw: flat/European jaw: tooth shape.
The common jaw breaking guard plate (above the jaw plate) is flat, and the European version uses tooth shaped guard plate, which can also participate in crushing when crushing materials, compared with the flat type guard plate, which increases the effective length of the jaw plate and improves the crushing efficiency. The toothed jaw plate can give the material more crushing force direction, which is conducive to the faster crushing of the material, the higher crushing efficiency, and the control of the product particle shape.
