DSMAC is a professional mining equipment manufacturer in China, it supplies stone crushers to India, Indonesia, Ghana, Russia, South Africa and so on.

Jaw crusher details

Jaw crushers are the oldest and one of the simplest sorts of rock crushers. A jaw crusher is a machine that uses two steel plates to crush rock. It is like a giant collapsible V made out of two metal crusher jaw plates. At the bottom, the jaw plates are very close together and at the top they are further apart. One wall is held still while the other is closed against it – usually about three times a second. When it closes, the jaw crushes the rocks inside it. Because it tapers, the rocks are crushed to smaller and smaller sizes as they go down, then dropped through the bottom.

Jaw crusher types for Indonesia

DSMAC supplies two types jaw crusher types for indonesia. They are double-toggle jaw crusher and overhead eccentric jaw crusher. The double-toggle model contains a swing jaw, a stationary jaw, an offset eccentric shaft, a pivot point and a double set of toggles. The overhead eccentric style is made up of parts which include a flywheel, adjusting wedges, hydraulic rams, a pullman, a sizing gap and a crushing chamber.

Jaw crusher working principle

To use a jaw crusher, rock must first be dropped between the machine’s metal plates. The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when moving jaw moves . So the moving jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.

How to select suitable jaw crusher?

It is important to select suitable jaw crusher, it will help the users to improve working efficiency and get good products. Common factors used to determine which jaw crusher to use include the size of the crushing chamber’s opening, the dimensions of the chamber itself and the design and material of the stationary plate. In some situations, a jaw crusher will produce the kind of crushed rock desired. In these instances, less-durable jaw plates will suffice.

Two commonly used methods adjust jaw crusher discharge opening

Jaw crusher is the common equipment used in mining industry, construction, highway, cement and other industry, then how to adjust jaw crusher discharge opening? In this article, we will share two methods: shim adjustments and wedge adjustment.

Jaw crusher applications

Jaw crusher has wide range of applications, including cement, mining, road building and other industries. In order to meet different customer choices, the crusher discharge opening needs to be adjusted to achieve the required materials specifications. Here we give two commonly used adjustments on crusher discharge opening:

Two commonly used methods adjust jaw crusher discharge opening

1. Shim adjustments.

Place in a group equal to the thickness of the spacer between the plate support and rack rear wall of the rear thrust to reach slim adjustments. We can also increase or decrease the quantity of the spacer layer, so that the discharge mouth of the crusher to decrease or increase. This method can be multi-level adjustment, and compact machine structure can reduce the weight of the equipment, but the adjustment must stop. Some types of jaw crushers always adopt this method to adjust, such as PE250 × 1000, PE250 × 1200, PE300 × 1300, PE500 × 1500, PE600 × 900, PE700 × 1000, PE900 × 1200, PE1100 × 1400 and so on.

2. Wedge adjustment.

Lying on the relative movement of the two wedges between the thrust plate bearing rack rear wall to realize the mouth crusher setting adjustment. Rotation of the nut on the bolt, so that the adjustment wedge for rising or falling movement along the rear wall of the rack, driving the front wedge to move forward or backward, thereby promoting the thrust plate or the movable jaw, in order to achieve the adjusted discharge mouth purposes. This method can achieve stepless adjustment, easy to adjust, save time, without stopping to adjust, but the increase in the size and weight of the machine. For example, PE400 × 600 and PE500 × 750 jaw crushers always adopt such an adjustment device.

Why jaw crusher attracts so many customers

New type jaw crusher with hydraulic safety device, reliable and safe, and easy to troubleshoot. Crusher rod equipped with a hydraulic cylinder and piston, cylinder and rod upper connection, the piston and the thrust plate bearing convergence. Normal operating pressure when the fuel tank is full of oil, equivalent to a whole rod piston and cylinder. When crushing chamber into the non-crushing objects, connecting rod force increases rapidly, the oil pressure in the fuel tanks of a sudden increase in, pushing liquid flow valve, the pressure oil is squeezed out, release the piston and cylinder. In this case, the link cylinder, though still with the rotation of the eccentric shaft and up and down movement, but the piston rod does not move, so the thrust plate and the movable jaw does not swing and play a role in the insurance apparatus. With the continuous development of hydraulic technology, this crusher will be widely used. However, it is worth noting that link the head of the bolt or flywheel pin (key) is not enough, as the jaw crusher insurance device.
