Mobile Jaw Crusher

What is a mobile jaw crusher

Mobile jaw crusher is the latest stone crusher machine and mainly used for metallurgy, chemical engineering, building materials and other industries which usually require moving work, especially the construction of high-speed way, railway. Customers can adopt several configurations according to different demands of raw materials, working scales and finished products.

Application area

The mobile jaw crusher plant greatly expands the application of coarse crushing, and it combines primary crusher with the secondary crusher (cone crusher or others), which has finer crushing size. The design principle of mobile jaw crusher is to stand in the customer's position, eliminate the obstacles of working sites and surroundings, and offer the facilities with the features of high efficiency and low costs.

The main equipment of mobile jaw crusher is fixed frame, jaw crusher, feeding machine, vibrating screen, conveyor, motor and control cabinet, etc. The outstanding feature of the equipment is environmental protection.

Main parts

So how can mobile jaw crushers be environmentally friendly?

From the aspect of feeding inlet--engineers found that when conveyor transferred materials to the inlet of jaw crusher, the dust will rise when materials falling. And this is the main reason for polluting working sites. 

However, the mobile jaw crusher overcame this problem by reducing the different height between the conveyor and the feeding inlet to restrain the dust flow and realize environmental protection.

From the aspect of inside structure--the dust of the material is not the main reason for environmental pollution, but the dust produced in the crushing operation is the fundamental cause.

The mobile jaw crusher optimizes and upgrades the crushing cavity of the jaw crusher, strengthening its tightness, so that the dust produced in the operation can stay in the crushing cavity and be discharged with the finished products. The dust can be discharged from the dust collector by sorting at the discharge port to realize the environmental protection of the mobile jaw crusher.

Mobile jaw crusher and fixed jaw crusher

When mentioning the jaw crusher used for the primary crushing, the insiders are very familiar with it. Thus, the mobile jaw crusher refers to the jaw crusher that is loaded by the mobile crushing plant. So compared with the fixed jaw crusher, what are the outstanding features and performances of mobile one?

It is not difficult to see through the table that the fixed jaw crusher has high requirements on the site and requires centralized feeding. Moreover, the fixed one and other crushing equipment are combined to form an integrated fixed crushing station which is a standard and upgraded working production line with complicated installation and not suitable for crushing requirements with strong mobility. But the mobile jaw crusher is relatively simple in structure, reasonable in installation, so the transportation is more flexible and convenient. In addition, mobile jaw crusher also has many other advantages and features.

Applications of mobile jaw crusher

Used for garbage

Construction waste has its characteristics as follows: diverse materials, mixed piles, different hardness, and the most important point is scattered distribution. To make full use of construction waste, a series of steps such as crushing and screening are required, and since construction waste is distributed in different places, it is better if the operations can be carried out hastily. At this time, the mobile crushing plant is the best choice for crushing construction waste!

After crushing, the construction waste is sorted, removed and crushed, and most of them can be reused as renewable resources, such as scrap steel, scrap iron wire, waste wire and various scrap steel parts. And then they are concentrated and re-heated for reproducing various kinds of steels; the bricks, stones, concrete and other scraps can be crushed and used for sand, plaster, concrete cushion, etc.

Construction waste crushing line

Used for sand making

With the advancement of technology and the increase in customer demand, mobile jaw crushers are favored by more and more customers, especially in the sand making industry with strong material mobility. Due to the large volume of the rock after mining, it is not ideal to use the secondary crushing machinery to crush it directly. Therefore, the feeder is required to feed the stone evenly into the feed port of the mobile jaw crusher for coarse crushing. And then, the larger size stones are transported by a conveyor to a sand maker for fine crushing.

There are many kinds of raw materials for sand making. Combined with the operating principle of the stone sand maker, it can be known that only when the processing raw materials are broken to the specified fineness and then crushed by the sand maker for a uniform particle size, so on the sand making line, the mobile jaw crusher will be used for primary crushing, and the produced large-sized stones are transported by the belt conveyor for deep crushing to produce high-performance sand.

Sand making line

Used for building bridges and roads

The construction of roads and bridges is the top priority of the country's infrastructure construction. The country's huge investment in the construction of roads, bridges and railways has supported the increase of the national economy. Due to the transportation distance, transportation mode, reserves and quality of natural sand and stone material are difficult to meet the requirements, more artificial sandstone materials are used. And the stone material production line technology has been developed.

The construction of road and bridge requires high-quality sand and gravel aggregates, while high-quality sandstone aggregates need to use high-quality crushers and sand maker. The stable and reliable complete crushing equipment is related to the quality and engineering effect of the whole project. The selection of equipment for the production line affects the quality of the product and the investment in the processing system. Moreover, due to the fixed site selection and long route of the road construction, the required materials are huge and inconvenient to transport, which means that the mobile crushing is the best choice for road building.

Customer cases

Considerations for selection of mobile jaw crusher

With the continuous development of science and technology, mobile jaw crusher technology in China continues to surpass the foreign technology, and the domestic market competition is fierce, and the mobile jaw crusher is much expensive. Therefore, the following matters should be paid attention when selecting the models of mobile jaw crusher.

  • 1. Have a certain understanding of the required equipment model, have a general budget for the cost, and choose a more accurate equipment model, which is more conducive to improving production efficiency and saving unnecessary expenses.

  • 2. Have a certain understanding of the raw materials of the production. Different processing of raw materials and different manufacturing materials of each part will lead to different costs. If the material quality is better, the price will certainly be more expensive.

    However, if the equipment does not match with the processing of raw material, it not only affects the production efficiency but also wastes the cost. Users about how to avoid unscientific configuration must pay attention to the strength and credibility of manufacturers.

As a Chinese manufacturer of mobile jaw crusher, HXJQ has been adhering to the responsible attitude for each product and every user and dedicated to serving users. If you want to buy a mobile jaw crusher, HXJQ will be the best choice.
