Hydraulic cone crusher has two kinds: single-cylinder and multi-cylinder,at present, China has been finalized for the single-cylinder’s. Single-cylinder hydraulic cone crusher, since the safety device and the adjusting device of port of discharge have made significant changes, therefore it has a quite large differences from the spring type and multi-cylinder hydraulic type on the mechanical structure, but in the crushing work principle is identical.

Present our country has manufactured several models of series of products of single-cylinder hydraulic cone crusher machine. Although it has still some problems in practice, such as oil spills caused by lax oil cylinder seal, etc. with the continuous improvement of machinery manufacturing industry, these issues can be resolved. At the same time, compared with the spring type, it has the features of small quality and volume, simple structure, convenient adjustment of discharge port, reliable over iron insurance, sensitive hydraulic system, easy to realize automatic control and so on. Therefore it has great development prospects.

The movement of movable jaw plate of jaw crusher is achieved with eccentric rod and thrust plate, which is composed of flywheel, eccentric shaft, connecting rod, front thrust plate and after the thrust plate (known as brackets). Two flywheels were installed at both ends of the eccentric shaft. Eccentric shaft supports in the bearing of rack on the wall. The upper rod mounts on the eccentric shaft, one end of the front and after the thrust plate supports on the groove of the thrust plate bearing of the lower part of both sides of the connecting rod, the other side of the front trust plate supports on the thrust plate bearing of the lower moving jaw, the other end of the after thrust plate supports on thrust plate bearing of wall rack. When the motor rotates through pulley drived by the eccentric shaft, the connecting rod moves up and down, so as to drive the thrust plate movement, and makes the formed angle of the front thrust plate and after the thrust plate change continuously and promote the moving jaw movement. To make the moving jaw plate swing back and forth around the suspension axis, thus crush ore. When the moving jaw swings forward, the horizontal bar through the spring balances the inertia force which generated by the moving jaw and thrust plate, to make the moving crusher‘sjaw and thrust plate combinat closely, not separate. When the moving jaw retreats, the spring can also assist.

According to different purposes, cone crusher can be divided into two categories:
(1) used to crusher coarse material. Currently the most widely used is the hanging shaft cone crusher, according to the different ways of discharge, this crushing machine can ben divided into the side of discharge and the center of discharge. Although the former can still be seen in some old concentrator, now it is no long manufactured, and now the most widely used is the center of discharge cone crusher.
(2) used to crushing equipment medium and fine material. According to the different shapes of crushing chamber, can be divided into standard, intermediate and short-type.
For the different purpose and structure, the cone crusher can be divided into coarse crushing, medium and fine crushing, but the working principle is basically the same. Now take the cone crusher which is used to crush coarse material for example to explain the working principle. Material enters from the upper, for the role of eccentric sleeve 4, which makes the moving cone do swing movement, close to and leave the set cone periodically. When the moving cone closes to the set cone, the effect of broken ore generates. In the left side the broken ore has been discharged from the crushing chamber. The working principle of cone crusher is similar to jaw crusher, so it can ben seen as a continuous work jaw crusher. The force of ore crusher, in addition to a crushing effect, there is bending and peel grinding effect, and work continuously, so the production capacity is much higher.

Impact crusher belong to high efficient crushing equipment which has nice features,simple structure,large crushing ratio, low energy consumption,large production capacity,particle size are all average,and the role of selective crushing, is a promising device. The crushing process of impact crusher is:the material enter the the rotor spinning counter-clockwise through the chain curtain ,after a strong impact of the hammer, fly to the first impact board according to tangent by a large speed,and after collision broken ,go back to the direction of the rotor, after a second impact by the hammer,part of the material (mostly small) fly to the first board ,some material from the crushing machine was broken several times,and finally the material achieve the requirement size is discharged from the bottom of crusher. But its biggest drawback is that board hammer and back impact plate are particularly prone to wear,especially in hard ore crushing ,abrasion is more serious and require frequent replacement.Present,because of the emergence of a number of wear-resistant materials,and in some metal ore dressing plant it has been applied.

Safety device is a safety gear when the crushing chamber of jaw crusher enters non-breaking material (eg. Iron, etc), in order to make the main components of the machine from being damaged. The most common is to use the latter thrust plate as the safety device of the crusher. The latter thrust plate is made of ordinary cast iron in general, and in which opens a tank or a number of holes in order to reduce the strength of its cross section; or by a combination thrust plate. When the crushing chamber falls in non-breaking material, the machine excesses the normal load, the latter thrust plate is damged and makes the crusher stop working, so that the main components of the crusher machine are not damaged.

During operation, jaw crusher mining machine must pay attention to be regular maintenance and repair. In the crushing equipment plant, the working conditions of jaw crusher mining machine is very poor. But the excessive wear of machine parts, or even fracture, are often due to the incorrect operation and ill repair. Therefore, the correct operation and careful maintenance is the important way to extend the using life of the machine and increase the running ratio of the equipment. In routine maintenance work, the operator should be able to correctly judge the equipment failure and accurately analyze the causes, so quickly to elimination.

Whether the machinery equipment can often keep good condition or not, in addition to the proper operation, it first depends on maintenance, and second on repair. And equipment maintenance is the basis for equipment repair. In use, it is necessary to properly maintain and inspect the equipment, but also should master the wear cycle of the parts, to early find the defects of the equipment parts, timely repair and replacement, so that the crusher can not reach the point that the equipment are scrapped for not being repaired. So the timely repair of equipment is the important link to ensure normal production.

A jaw crusher is a type of primary crusher used in mines and ore processing plants. It works by crushing rocks and ore between two jaws, one of which is stationary and the other moving. The moving jaw is pivoted at the top and moves back and forth, while the stationary jaw is fixed.

There are several types of jaw crushers:

Blake jaw crusher: This is the most common type of jaw crusher. It has a fixed jaw and a moving jaw pivoted at the top. The crushing chamber is wider at the top and narrows towards the bottom.

Dodge jaw crusher: Similar to the Blake jaw crusher, the Dodge jaw crusher has a fixed jaw and a moving jaw pivoted at the bottom. The crushing chamber is wider at the bottom and narrower at the top.

Universal jaw crusher: This type of jaw crusher has a fixed jaw and a moving jaw pivoted in an intermediate position. It can crush materials of various hardness levels.

Overhead eccentric jaw crusher: In this type of jaw crusher, the eccentric shaft is located above the jaw and moves the moving jaw back and forth. It is used for coarse and medium crushing of hard and abrasive materials.

Double toggle jaw crusher: In this type of jaw crusher, the moving jaw is pivoted at the bottom and swings in an arc. The toggle plate and the toggle seats are positioned on opposite sides of the pitman. This crusher is used for primary crushing of hard materials.

Jaw crushers are widely used in the mining and construction industries and are known for their high efficiency and reliability.

Limonite is an ore consisting of a mixture of hydrated iron III oxide-hydroxide of varying composition. The generic formula is frequently written as FeO OH nH2O, although this is not entirely accurate as limonite often contains a varying amount of oxide compared to hydroxide.

Together with hematite, it has been mined as an ore for the production of iron. Limonite is heavy and yellowish-brown. It is a very common amorphous substance but can be tricky to find when mined with hematite and bog ore. It is never crystallized into macroscopic crystals but may have a fibrous or microcrystalline structure and commonly occurs in concretionary forms or in compact and earthy masses, sometimes mammillary, botryoidal, reniform or stalactitic. The color presents various shades of brown and yellow, and the streak is always brownish, a character which distinguishes it from hematite with a red, or from magnetite with a black streak. It is sometimes called brown hematite or brown iron ore. It is not a true mineral and is composed of a mixture of similar hydrated iron oxide minerals, mostly goethite, with lepidocrocite, jarosite, and others. Limonite forms mostly in or near oxidized iron and other metal ore deposits and as sedimentary beds. Limonite may occur as the cementing material in iron-rich sandstones. Also known as the Lemon Rock.

Limonite has been known to form pseudomorphs after other minerals such as pyrite, meaning that the chemical weathering transforms the crystal of pyrite into limonite but keeps the external shape of the pyrite crystal. It has also been formed from other iron oxides, hematite and magnetite, the carbonate siderite, and iron-rich silicates like some garnets. It is named from the Greek word for meadow, in allusion to its occurrence as “bog-ore” in meadows and marshes.

If you want to run a limonite crushing plant, there are several necessary equipment that you may need in the production line. These include:

• Jaw crusher: This equipment is used for the primary crushing stage to crush limonite ore into small pieces.
• Cone crusher: The cone crusher is used for the secondary and tertiary crushing stages. It can crush limonite ore into smaller sizes and produce more fine particles.
• Vibrating feeder: This equipment is used to feed the limonite ore into the crushers continuously and uniformly.
• Vibrating screen: This equipment is used to screen out the different sizes of limonite ore particles after the crushing process.
• Belt conveyor: This equipment is used to transport the limonite ore from one machine to another in the production line.
• Magnetic separator: This equipment is used to separate the magnetic iron from limonite ore.
• Sand making machine: This equipment is used to produce artificial sand from limonite ore that can be used in construction.

The specific equipment needed may vary depending on the size and complexity of your limonite crushing plant.

Choosing the right crusher for your application can greatly increase efficiency and reduce cost. Here are some factors to consider when choosing a crusher:

• Type of material: Different crushers are designed to handle different types of materials. For example, a jaw crusher is suitable for crushing hard, abrasive materials, while an impact crusher is better for softer materials.
• Capacity: The size and capacity of the crusher should match the needs of your operation. If the crusher is too small, it may not be able to handle the volume of material, while if it’s too large, it may be more expensive to operate and maintain.
• Reduction ratio: This refers to the size of the material that the crusher can reduce to. A higher reduction ratio means that more of the material will be crushed, resulting in smaller particle sizes.
• Operating cost: Consider the cost of operating and maintaining the crusher over its lifetime, including energy consumption, maintenance, and repair costs.
• Mobility: If you need to move the crusher frequently, consider a mobile crusher, which can be easily transported to different locations.
• Environmental impact: Choose a crusher that minimizes environmental impact, such as by using recycled materials or reducing dust and noise pollution.

With the continuous process of urbanization, the generation of construction waste in cities is also growing rapidly. While people are enjoying the urban civilization, they are also suffering from municipal waste, including construction waste, which takes up a large proportion and accounts for 30% to 40% of the total garbage. According to some information, rough statistics on construction material waste of brick-concrete structure and frame construction reveal that in the construction process of 10,000 square meters, only construction produces 500 to 600 tons of residue. It will reach hundreds of millions of tons if architectural ornament removal and rebuilding, and construction materials are included. Therefore, dealing with and reusing an increasing amount of construction waste has become an important topic for government departments at all levels and construction waste disposal units.

A significant amount of construction waste can be reused as renewable resources after sorting, removing, or crushing. For example, scrap steel, scrap iron, scrap wire, and various steel accessories can be reprocessed into a variety of steel products after sorting, collecting, and remelting. Bamboo wood waste can be used to make man-made timber. Brick, stone, concrete, and other waste can replace sand after crushing and used for masonry mortar, plaster mortar, hit the concrete layer, etc., and can also be used to make bricks, road bricks, lattice bricks, and other building materials. Therefore, we must insist on comprehensive utilization in construction waste disposal.

In the process of urbanization, rubbish was once a burden on urban development, and many cities in the world were once besieged by rubbish. But today, rubbish is considered to be the most potential for development, an inexhaustible “urban mine,” and “misplaced resources.” This is an in-depth understanding of rubbish and also an essential requirement for urban development.

With the emphasis on environmental issues gradually increasing, energy saving and environmental protection have become the themes of national development and have begun to provide industrial development opportunities for garbage disposal. The world’s rubbish increment speed is 8.42% per year. Renewable resources have become a new starting point for resource recycling and an important component of the recycling economy. Moreover, it not only solves the shortage of resources but also reduces junk emissions during the recycling process of waste resources and waste materials, which can be described as a “double benefit.” Government leadership has begun to pay great attention to landfill construction and increased investment in it, so we can predict that there is a bright future in the waste disposal industry.
