A cone crusher is generally used as a secondary crusher in a crushing circuit.
At present, 10 billion tons of industrial solid waste heap stock, which was used only about 50%, but also the remaining half of the solid waste of less than timely processing and utilization. Solid waste rate of 1 billion tons per year, polluting the ecological environment, affect the health of people’s lives, so the comprehensive utilization of industrial solid waste is imminent.
With the accelerated industrialization and urbanization process in China, industrial solid wastes produced upward trend year after year. The same time stimulate the further increase of the industrial areas of resource consumption; the supply of resources is increasingly tense.
The body of inertia cone crusher is located in the vibration isolation system. Set the shear elastic of vibration isolation system as K. the total mass of material in the crusher is M. the inertia force in any direction can be simplified as spring mass system by horizontal circular system. Because there is always hinder in the real vibration system, the free vibration force will decay with time growing, and the crusher is basically vibrate according to the vibrating regular of the second part.
The amplitude of crusher is infinity, which is known as resonance. When we choose vibration isolation system, we must make the natural frequency away from the frequency of inertial force to avoid the occurrence of resonance. The smaller the frequency the less force passed to the foundation. So, we should keep the frequency as small as necessary. With the certain mass of material in the crusher, we must use the spring with small shear elastic as vibration isolation elements.
Therefore, the aeration pulp during the flotation is called triphase system. While flotating, each mineral particle’s adhesive selectivity for the bubbles as well as their flotation behavior are determined by the physical and chemical property among the triphase boundary composed of mineral particle, water and bubbles. Among them, the wettability of the mineral surface is much more important. For instance, dropping a drop of water on a smooth and clean quartz surface, then the water drop expands quickly, that is to say the quartz can be wetted, it is hydrophilic; and again dropping the water drop on paraffin, the water drop remains a ball shape instead of spreading about, viz, paraffin is not that easy to be wetted by the water, so it is hydropobic. That is called wetting phenomenon. In order to increase the flotation machinery efficiency, the development of the new type machine has generally gained much more attention, especially in the recent decade, this machine is developing quite fast.

Jaw crusher is a very important machine
that is used for crushing large stones and rocks. It is the basic tool used in stone quarries, limestone mining areas and even construction sites. It has made mining of stones and basalts so easy and faster today unlike when the mining activity was still done manually using simple and archaic tools. The equipment crushes large rocks into smaller ones and can be used further to grind small particles into finer material. Stone and limestone mining industries are known for the emission of large clouds of dusts and loud noises produced by machines which have negative effect on both the workers and people living near such areas. However, this nuisance has been greatly solved by the introduction of jaw crusher which is worker and environment friendly and produces less dust and low noise. The machine also has large feeding or carrying capacity that allows crushing large quantities of stones at a faster rate.
As well known to all, South Africa is rich with gold ore. Gold is a kind of decoration and the value do not easily devalue. To make best use of the gold ore, it will need the gold mining machine to eliminate the undesired impurities from gold ore. Small mobile ball mills for gold mining is the vital machine in the whole mining process.
Gold mining process:
The raw materials is mined using explosives and quarrying. Large boulders are transported to big crushers that crush the rock material into smaller grain size. Various sizes of crushers, both stationary and mobile, are used at mines. Among the types used are primary gyratory crushers, impact crushers, gyratory crushers, cone crushers and jaw crushers. The material to be crushed is fed into the crusher either via a conveyor.
After crushing, the rock material is ground in small mobile ball mill for gold mining. There are a variety of different grinding mills, including rod and ball mills. In the grinding mills, the impact of the minerals grinding against each other and against the steel balls in the mill breaks down the size of the minerals even further. The mining process also includes a vibrating screen that sorts the crushed material into desired grain sizes. Rock material is extremely hard and thus it wears down the crushers and grinders. Therefore the wear parts, like the various blades and rotors and the liners of grinding mills, must be replaced regularly.
In the mineral process valuable minerals are concentrated by removing unnecessary substances from the excavated gold ores. The first phase of the process involves reducing the size of the mineral. This is done in crushers and grinding mills where the ore is broken down into smaller pieces. When the fragments of ore are small enough, the pieces containing the most valuable minerals are separated from those containing mostly unneeded minerals. The separation process involves leaching, emission, gravity methods and magnetic separation. Emission chambers and pipes, coils and magnetic separation equipment are used in the separation process. Water must also be extracted from the concentrated product. Coils, filters, thickeners, sedimentation basins and dryers are used to do this.
In the next phase, metal is extracted from the mineral. Extraction methods vary depending on the product, but the main methods are pyrometallurgy (a metal production method employing high temperatures), hydrometallurgy (producing metal by leaching the raw material and flocculating the pure metal from the solution) and electrometallurgy (a metal production method applying electricity). Electrolysis, a forced oxidation-reduction reaction achieved using electric current, is an integral part of electrometallurgy. Electrolysis can be used to produce very pure elements.
After the extraction phase, the metals still contain impurities, so they must be purified. The refining process uses heat, chemicals and electricity. Electrowinning is used in gold refining.
The cone crusher is common crushing equipment
widely used in industrial production, which is mainly used in mining, smelting, building material, high, railway, water conservancy and the chemical industry sector. The cone crusher in our country develops slowly and the efficiency of the cone crusher is very low. In order to improve the the efficiency of the crusher and achieve energy saving in crushing field, it is necessary to have a deep study on cone crusher. There are lots of factors to influence the performance of the cone crusher, including the structure of the cone crusher, the operational factors and so on. These factors have different impact on the performance of the cone crusher, such as the efficiency of the cone crusher, the particle size of the products and the energy consumption. Therefore, it is necessary to establish a multi-objectives optimization model to optimize the performance of the cone crusher. The operator must observe and note the followings to ensure the good performance of the cone crusher. First, the feeding ore must be uniform and the sizes of the products must meet the requirements. Second, pay attention to the ore discharge and the operating condition of the transport belt to avoid the clogging accident. Third, regularly check the pumps, coolers, filters, the amount and temperature of the fuel. The fuel return temperature should be less than 60℃. Forth, check the drainage. Do not operate the machine without water. Fifth, pay attention to the oil pressure of the locking cylinder. The adjustment ring only can be operated in locking status. Sixth, regularly check the wear of the liner. In particular, pay attention to the retaining bolt of the liner.
Faced with such rapid development market and gradually mature market opportunity, domestic sand and artificial building of sand booming demand, so relevant industry sand aggregate of the grain of line, yields raised very tall requirement, thus crusher, hammer apparatus, etc have higher standards and requirements.
Along with the rapid development of China’s economy, high iron the construction of a day. Especially in the specialized manufacturing technology level, its influence on the whole building industry development in our country.
Modern industrial manufacturing, high speed railway construction and operation, high speed road construction, is inseparable from the sand aggregate. And in the high speed railway construction of concrete sand aggregate grain shape, gradation out the high requirements, especially basalt (fai green rock) in the rubble needle flake. In February 2010, 6 high iron success operation of zheng west, the logo is not only the passenger structure and railway transportation present situation, the greater is the high iron along will form a gold belts.

Small crushers are usually used to crush solid samples in laboratory, but how can we choose suitable ones?
1. Crushers for High humidity solid materials
We have tested and find that hammer crusher can crush materials with moisture content less than 25%, while jaw crusher can crush materials with moisture content less than15%.
hammer crusher is more suitable to crush high humidity solid materials
2. Working Efficiency
We will use a jaw crusher and hammer crusher with the same inlet size to test, the materials we used is around 25mm, we will set the output size as 5mm.
Materials are put in the crushers by a mini belt conveyor, jaw crusher can produce 2 tons per hour while hammer crusher
can produce 500kg. Even the crushing ratio of jaw crusher is about 60%, it is more efficient than hammer crusher.
3. Evenness of final product
Crushing ratio of jaw crusher is 60% while hammer crusher is 100%. Hammer crusher is better to get evenly final product
4. Feeding size
To compare the capacity of hammer crusher and jaw crusher with same inlet size. The biggest materials jaw crusher can crush is 80mm, but hammer crusher can only crush materials smaller than 30mm.
5. Finest output size
Distance between the jaw place can not be smaller than 2mm, or else they are easy to bump each other, what is more, the big materials may block the outlet. The finest size jaw crusher can do is around 4mm.
The output size of hammer crusher is depend on the sieve plate. The finest sieve hole is 1mm. That is to say, final product bigger than 1mm can not get out of the crusher and will be recrushed.
Hammer crusher is better than jaw crusher in fine crushing.
