The portable jaw crusher is widely used in mining, building material, highway, railway, water conservancy and chemical industry. All kinds of ores and crushing rocks of medium size such as quartz lump ore have a good effect. Coarse crushing equipment which is often used is cone crusher and jaw crusher. In order to correctly select and rationally use the jaw crusher and cone crusher, now we should briefly analyze the differences of the two kinds of crushers.

Jaw crusher is used to the medium size crushing of all kinds of ores and large materials and widely applied in the industries of mine, smelt, building, highway, railway, water conservation and chemical engineering. The highest compressive strength of broken materials is 320MPa. The performance of it is big-broken, granularity-product, simple-construction, reliable performance, convenient maintenance and low operating costs.

Marked by high durability and excellent crushing performance, cone crushers are well adapted to meet a number of requirements. Generally speaking, a cone crusher consists of a fixed crushing jaw and a moveable jaw. Driven by a toggle plate system, the two jaws constitute a wedge-shaped crushing zone so that sand and other tiny impurities can be crushed in the zone in a centrifugal way.

No matter what you are doing, building a house or constructing a road, in order to build the base of the structure, you may need the rock's help, certainly, what you need is not the raw rock, but the processed rock with much smaller size. Why is the rock needed? Because it is strong enough to hold up the total weight of the structure. And now the problem we are facing is that how to get rock materials with much smaller size. Generally speaking, the raw rocks directly mined from the ground are always with large size, for instance, some of them may be as large as your bedroom or even larger, and in this case, in order to get suitable raw materials, we need the help of the jaw crusher.

Jaw crusher or vibration in the process of running under torque is bigger, often triggered by heavy system liability. They are commonly: the pulley and shaft head a gap caused by the axis head and the wheel wear and force of eccentric shaft bearing wear and so on.

In the use of jaw crusher appliance, we should do the pursuing actions to properly guard the appliance and to maintain the jaw crusher.

Mobile jaw crusher is entirely adjustable to all mobile crushing calls for. It arranged new assortment of company possibilities for contractors, quarry operators, recycling and mining apps.

Jaw crusher is widely used in mining, smelting, building materials, highway, railway, water conservancy and chemical industries for crushing various materials whose compressive strength less than 320 MPa.

The pendulum jaw crusher is driven by the accentric shaft and the upper part of the crusher is near to the circle. In comparison with the lower part of the pendulum jaw crusher, the upper level is approximately 1.5 times. It can reach the requirement of the upper large ores in the crushing chamber.

As one of the most common crushing equipment, jaw crusher is mainly applied in crushing the large and hard things, such as rocks and mental with the compressive strength under 320Mpa. This crusher is usually used in many applications such as mining, metallurgy, road & railway construction, water conservancy, chemical industry and so on.

Ancient crushing machinery was created one after another after the gradual promotion and perfection of the steam engine and other motive power machines. In 1858, the American people Black invented jaw crusher which is capable of breaking rocks; In 1878, the United States developed spiral crusher with continuous crushing actions, and its production efficiency is higher than the jaw crusher with interval crushing actions.

The jaw crusher effect is evident and efficient in construction and building process. Many materials can be dealt with by the machine, such as stone, rock, ore and others. With big and strong force, materials can be handled into required shapes, volume. We can say that the crushers are versatile, as it is very suitable for many applications. Some of them can be not only used for secondary stage, but also primary crushing. In sand making process, it makes great effect so that when there is a need, you are supposed to have one.

Mining crusher is also called rock crusher for mining use, which refers to the crushing machine whose discharging granularity is more than 3 mm account for more than 50% in total discharge capacity in layout. Crushing work includes rough crushing, middle crushing as well as fine crushing according to the size of the feeding and granularity. The sandstone equipments that the commonly utilized are jaw crusher, strike crusher, compound crusher, vertical crusher, spiral crusher, double roll crusher, etc.

Sand washer which works with the jaw crusher is gravel (sand, natural sand) washing equipment. Sand washer is widely used for the washing of the material in gravel pits, mine, building materials, transportation, chemical industry, water conservancy and hydropower, concrete mixing stations and other industries.

After starting, sand washer shall work with the jaw crusher should first idle for 2 ~ 3min, and then go on feeding work after conforming without abnormal phenomenon.

There are mainly following 4 kinds of rock crusher : hammer crusher, jaw crusher , impact crusher and cone crusher . We can buy rock crusher online or from slid shops. Whether we buy crushing equipment online or not, there are some notes we should put high attention to.
