Jaw crusher is commonly known as jaw break, also known as tiger mouth. The crusher is composed of two jaw plates, the moving jaw and the static jaw, which simulate the movement of the animals'jaws and complete the material crushing operation. Widely used in mining, building materials, highways, railways, water conservancy and chemical industries in a variety of ore and bulk material crushing. The maximum compressive strength of crushed material is 320Mpa. But the jaw crusher occasionally has the problem of discharging, so do you know how to solve it? Let's take a look at it. Although

jaw crusher equipment has two types of simple swing and complex swing, but their working principle is basically similar, but the moving trajectory is quite different.


simple swing hull crusher, driven hull is suspended on the supporting shaft, so when the moving hull is reciprocating movement, the moving hull of the upper points of the trajectory is a circular arc, and in the horizontal range small and large, and the bottom of the moving hull (at the mouth of the mine) is the largest. As the ore falling into the crushing chamber, the upper part of the ore are all large blocks, so often can not reach the required compression of ore crushing, so the upper large ore, need to be repeatedly crushed many times before it can be broken. As we all know, the outlet (discharge port) of the frontal crusher can be adjusted according to the user's needs to obtain qualified product material size.


First of all, we must be clear that the jaw rock breaker thrust plate, also known as the elbow plate, in addition to transmitting power to make the moving plate swing back and forth, but also has a safety and insurance role, changing its length can also play a role in regulating the discharge port.


When the crushing chamber of the Ordos crusher enters the non-crushing objects (such as iron balls, iron blocks, etc.), the rear thrust plate is used as the safety part of the crusher to protect the main parts of the equipment from damage. The rear thrust plate is generally cast in cast iron, with a slot or a number of holes in the middle to reduce its cross-sectional strength can also be cast into two pieces, and then connected with screws (or rivets) to form a composite thrust plate.


When the unbreakable material enters the crushing chamber, the equipment is overloaded, and the huge crushing force is transmitted to the thrust plate, which causes the thrust plate to break or the screw of the combined thrust plate to cut off, and the machine stops working, thus playing an insurance role. The lining plate of


crusher will wear and tear continuously with the increase of service time, which makes the discharge port bigger and the product size coarser. Therefore, in order to obtain the required size, it is necessary to adjust the size of the discharge port (i.e. the discharge port). There are two main methods to adjust:


, gasket adjustment, that is, the rear thrust. A set of gaskets is placed between the back of the support seat of the plate and the back wall of the frame, and the number of gaskets is increased or reduced or the thickness of gaskets is changed, so that the purpose of regulating the discharge outlet can be achieved. This method is compact in structure and reliable in regulation. This method of adjustment is used in large and medium-sized crusher.

2, wedge adjustment, is placed between the back seat of the thrust plate and the frame of the two wedge adjustment, suitable for small crusher. Above

is the solution to the discharge problem of

jaw crusher, hope to help everyone. Eight hundred and eighty-eight thousand one hundred and elevenUHBTDHJ2hS0=
