Jaw Crusher

Jaw crusher is used to reduce the sizes of different ores, which is widely used in the field of mining.

Jaw crusher is used as the primary crusher for the ores and rocks with different hardness so that people sometimes call it primary jaw crusher. Since the advantage of large crushing ratio, big crushing force, easy to maintain, low failure rate, it is a suitable choice for the mining industry.

How many types does the jaw rock crusher be divided?

Jaw crusher has been updated for three times. There are different types and series of jaw crusher. The primary serie was researched and developed as the PE jaw crusher. In order to improve the quality of the jaw crusher, Henan Fote Heavy Mining Machinery which is a jaw crusher manufacturer in China actively introduced advanced technology from German to produce another serie of jaw crusher (HD) with a larger crushing ratio and higher output capacity. HD series of jaw crusher is better than PE jaw crushers, and it is also called concrete jaw crushers. After researching from the market and the feedback from users, FTM machinery developed the European version jaw crusher(CJ).

Comparing with the HD jaw crusher, the CJ has more advantages. It is assembled by the non-welded structure, so it’s easy to disassemble and transport. Besides, a motor is installed at the end of the machine. Therefore, the CJ jaw crusher has been popular among the majority of users. Besides, we also have many types of mobile crushers and crushers plants.

How does the jaw rock crusher work efficiently?

1.Excellent casting engineering. Jaw crusher is made up with rack, seesaw, side guard, eccentric shaft and transmission. The eccentric shaft, made of high carbon steel, is the core part of the jaw crusher and has a large bending torque. The seesaw simulates the two movements of the animal to complete the material crushing operation.

2.High production capacity. We use oversized bearings and forged spindles, design a low suspension motion mechanism to achieve the larger crushing ratio. It has a deep cavity to crush efficiently.

Steep nip angle reduces wear on the jaw mold and accelerates material flow down the chamber, which reduces the operating costs. The stroke is enlarged from top to bottom, causing it to be the longest at the bottom of the cavity, which increases capacity and reduction ratio. Therefore, the jaw crusher can process the raw material highly in various operations.

3.Easy operation and low failure rate. The jaw rock crusher is designed in a modular manner and can remotely monitor and adjust the settings of feeders, crushers, and conveyors. They can be installed in a few days, saving installation costs. It was equipped with a lubrication system, so it’s easy to work and maintenance.

4.Environmental protection. Gasket type discharge adjusting device, large range of discharge adjustment, can meet various processing requirements of customers.

5.Using high wear-resistant tooth plate. Because of this high-quality crusher jaw plate, it can perfectly realize longer service life and cost-saving.

What raw materials can the jaw rock crusher process?

Jaw rock crusher is used in the first process of crushing various mineral rocks with compressive strength no higher than 320MPa, such as the river pebble, calcite, granite, aggregates, quartz, concrete, dolomite, bluestone, iron ore, limestone, construction waste, etc. Because of its different materials, the jaw crusher can be called the rock jaw crusher, concrete jaw crusher, gold jaw crusher and so on.

Different raw materials

Raw materials that the jaw crusher can process

Jaw crusher plants case1

Jaw rock crusher plant case1: Its main material is the aggregates, and the finished products of the jaw crusher machines are used for local hydropower infrastructure construction. The three-stage project includes the jaw crusher, cone crusher and sand maker to process the pebble, among which the jaw crusher is used for the primary machine. The aggregates can be crushed into the medium granularity one time.

The granite is very hard, so the requirement on the wear resistance of the machine is very high. We recommend the big jaw crusher HD125 950*1250 firstly, which can reduce the cost. Then, the cone crusher crushes further and the sand maker will shape the granite particularly and evenly. This guarantees the quality of the finished product.

How does a jaw crusher work?

When the jaw crusher is working, the movable jaws periodically reciprocate the jaws, moving up and down. When approaching, the material is crushed by crushing, splitting, and impact between the two jaws. When leaving, the broken material is discharged from the discharge port by gravity.

The maintenance of jaw rock crusher

1.Keep the jaw crusher clean. What we should note is that the impurity such as dust can’t be into the lubricant system and parts. On the one hand, the impurity can damage the lubricant film and the machine will lose the capacity of lubrication. On the other hand, the impurity itself is a kind of abrasive material and it will accelerate the consumption of the jaw crusher to shorten equipment’s life. Therefore, clean maintenance of the lubricant system is important to the jaw crusher whatever it is the large jaw crusher or small one.

2.Cleaning the filter of the lubricating oil with gasoline regularly. Then, we can use it until it is completely dry.

3.Changing the lubricant every six months. This will keep the crusher work flexibly and continuously.

Parts service

To extend the life of crushers and reduce your losses, as one of jaw crusher dealers in china, we can also provide you with the high-quality jaw crusher parts like frame part, seesaw, bracket, crusher, lubrication system, etc. Although we are one of Chinese jaw crusher manufacturers, we sale our products all over the world and the price of jaw crusher is affordable to our customers. Thanks to the great initiative of Chinese Government One Belt and One Road, we’ve gotten a lot of partners from India, Zambia, Ethiopia, Pakistan, etc.

Jaw crusher testing

We’ve had a customer ask to see some of these granite slabs run down through one of our 10 by 16 jaw crushers. It’s run from a 20 hourse electric motor, and we power with a 30 kilowatt generator. Here are the jaw plates, high maganess steel, so they work harden over time. We put hopper on top, because most of rocks we’re crushing tend to pop out. This unit weights about 6,000 pounds. We can put it on a stand for you. And he makes cut stone monuments and headstones and dies an he has a lot of cuttings and things that he needs crushed up for waste and once they’re crushed he can make a usable product out of it. These pieces are 18 inched by 15 and the thickness is about 7 or 8 inches. This one here is about 4 and a half. There is a big one over here that’s about 8 inches wide. So we are going to put these rocks though the 10 by 16 jaw crusher and make gravel.

So here is the material we crushed, this is the green granite. And we have it set at about an inch and a half discharge. You can see it makes some fines and some smaller stuff.

How much is the best jaw crusher?

To price of the jaw crusher, it depends on your model choice or your project plans. That means, the model choice is dependent on your project information like raw material, feeding size, discharging size and capacity demand. In general, if you just want to crush rocks at your home and backyard, small or mini jaw crushers would be the best choice for you because they can perfectly work at the limited spaces and cost a little. Otherwise, the big jaw stone crushers would be great, which means how much does the jaw rock crusher cost depends on customers’ various needs. At FTM company which always devotes itself to manufacture the best Chinese jaw crushers, we have small and mini jaw crushers as well as big one for sale.
