Jaw crusher

What is a jaw crusher?

One of the types of crushers is the jaw crusher model, which is used in the most basic process of crushing rocks and is responsible for crushing rocks and processing minerals and sand. The jaw crusher is exposed to wear during continuous operation, and the parts and materials used in its construction are made of manganese steel, which reduces friction and wear in the crushing process and increases the life of the parts. The size of the jaw in the jaw crusher is determined by the size and rectangular shape of its upper inlet opening.
In the first stage, a jaw crusher is used for ore dressing in factories. Its function is that the rocks in this device are crushed under the pressure of two plates, one fixed and one movable, with shear and compression forces between the two plates. The capacity and size of this jaw crusher vary. This jaw crusher is used to crush up to 6,000 tons per hour for stones and materials.
Advantages of Jaw Crusher Despite its simple structure, the jaw crusher is a basic and introductory tool in various industries. This type of crusher is often used to reduce the size of rocks. The most important advantage of this machine is crushing rocks such as clinker, iron ore, quartzite, etc., which are very hard and erosive. High capacity Easy and economical maintenance Sturdy body Stable performance High strength and power Low wear Very simple lubrication system Low costs of spare parts Easy repair and maintenance High production efficiency All models of Mumtaz Crusher Company are Single toggle type. The crushing factor in this jaw crusher is the force of pressure and impact. In order to achieve high productivity, Mumtaz Crusher Company produces the wear parts of jaw crushers from wear-resistant alloys such as manganese steel, and all roller bearings are licensed by reputable European companies. How a Jaw Crusher Works
The main function of a jaw crusher is to place the stones between the two jaws in the device and subject them to pressure and impact, resulting in their crushing. It is known as a jaw crusher because of the presence of two jaws in the device. In this type of crusher, the stone is crushed with shear and pressure force. This force is formed in two jaws, one side of which is fixed and the other side is movable, one is smooth and the other is wavy, and the crushing of the stones is done in these conditions. One of the important points in a jaw crusher is the dimensions of the feed opening (inlet). At the end of the work, all the crushed materials are discharged from the device.

Types of Jaw Crushers

A jaw crusher is used to break and crush stones, and each stone reacts differently in the crushing process, depending on its hardness and other characteristics. Depending on the type of stones, the device you choose is different. This type of jaw crusher is divided into two categories regarding the function of the jaws:
Fixed jaw
Moving jaw
This jaw crusher is divided into two important jaw models as follows:
Single-arm
Double-arm
Single-arm: In this type, the jaws move up and down, forward and backward, and less pressure is applied to the stones and both jaws. It has a smaller feed opening and is suitable for hard stones.
Double-arm: The two jaws move back and forth in a coordinated and oscillating manner. It has a larger feed opening than the single-arm type and higher pressure. The main application of this type is for very hard and hard stones. The shape and continuous oscillating movement in double-arm jaws are clear. These jaws also move back and forth. The double-arm crusher is used for hard and very hard stones. The inlet opening is larger than the previous model (capable of crushing larger stones) and the pressure between its jaws is also greater.

Jaw Crusher Specifications

Like any other crusher, the jaw crusher also has its own technical specifications. These specifications are usually divided into the following categories:
Crusher weight
Crusher dimensions
Jaw crusher capacity
Of course, the mechanical specifications of the jaw crusher are a function of these specifications. That is, the power of the electric motor causes changes in the weight, capacity, and dimensions of the device. The greater the power of the motor, the more natural it will be that the crushing power of the stone will be greater, and as a result, the capacity and dimensions of the jaw crusher will increase. In the following, before we examine the weight and capacity of the jaw crusher, it is better to first familiarize yourself with its components.

Jaw crusher components

This machine consists of the following main parts:
Power transmission components
Power generator
Jaws – tension rod and spring
Body
Product size adjustment device
Fixed jaw
Movable jaw
Jaw crusher shaft
Movable jaw shaft
Crusher jaw armor
Shaft bearing
Belt or pulley wheel
Adjustment screw
Movable jaw return spring
Movable jaw arms

Jaw crusher weight and dimensions

As for weight, the greater the distance between the two jaws, the longer the jaws will be, and as a result, more materials will be used in the construction of the jaw crusher. In this case, the weight of the jaw machine will vary and is between 6,000 and 27,500 kilograms.
Another point that should be noted about the weight of the jaw crusher is that the weight of a single-arm jaw crusher is much lighter than the weight of a pair of toggle crushers. It is even said that the weight of a double-arm crusher is twice that of a single-arm jaw crusher. Basically, the higher the weight of the jaw crusher, the higher its price will be due to the materials used.

Jaw Crusher Capacity

When talking about the capacity of a crusher, it means the amount of production that is received from the machine. This production rate is calculated based on tons per hour. If you look at the picture of a jaw crusher, you will notice that there is a distance between the two jaws at the top of the machine, which decreases as we go down the machine. The distance between the upper opening and the lower distance is called the bottleneck. The capacity of a jaw crusher is a function of the distance between the opening and the bottleneck of the machine. The greater this distance, the greater the input of the machine and the greater the output capacity of the machine; but two points must be considered.
First, the capacity of the jaw crusher will increase with increasing the speed of movement of the moving jaw; but this increase in capacity is up to a certain limit, and after that, the machine will no longer be able to crush all the stones and the capacity will be constant. To increase the capacity, if we increase the speed, we need to change the distance between the jaws and the weight of the jaws so that more stone is crushed during the movement of the jaw and the pressure exerted on the stone.
The second point that is very important and vital is the throat distance, which should not be less than a minimum. Although by reducing this distance, more stone remains between the jaws and more crushing occurs; but if this minimum throat distance is less than a certain size, it will affect the performance of the jaw crusher and cause a decrease in capacity and even the possibility of breakage of the shaft and bearing of the device.
Many tables have been written in cyberspace regarding the capacity and weight of the crusher machine. Since the capacity of the crusher machine can be changed depending on the customer’s order and manufacturers can change the capacity and weight of the machine to make the jaw crusher application desirable for them; therefore, for more information about the weight and capacity of the machine, you can contact our experts so that they can better guide you with the correct information.

Jaw crusher price

The jaw crusher machine is also manufactured in Iran and different prices are offered in the market for this machine. In addition, the dollar price also fluctuates every day and the manufacture of this machine requires steel products that see high price fluctuations in the market; Therefore, a specific price cannot be stated for this machine. To inquire about the price and how to sell a jaw crusher, contact the experts at Mumtaz Stone Crusher. It is better to pay attention to the following points when inquiring about the price:

Dimensions of the machine

The difference in the dimensions of the machine will not change the way the jaw crusher works; but it will change the capacity of the machine.
Material of the parts
In the manufacture of a jaw crusher, for example, what kind of steel is the jaw shoulder made of? What is the material of the rod of the machine? Or what kind of steel is the crusher armor made of? It affects the performance and price of the jaw crusher.
