Cone Crusher Parts Replacement

Cone crusher crushing ratio, low energy consumption, high efficiency, and a uniform particle size, suitable for crushing and fine crushing of various ores, rocks, often used as a two and three broken broken, widely use. So, various parts of the cone crusher if damaged, how to replace it? Shanghai Sanme will introduce six parts replacement method!

(1) wall replacement cone crusher, cone crusher wall is fixed on the head with a tapered conical body and zinc alloy, new installation or replacement of a new cone crusher working 6-8 hours casting wall between the two, you should check fastening, found loose to be tightened immediately.
(2) gear, due to friction and wear of the circular plate, the impact of changes in the gear gap, to ensure the normal gear must be covered with additional pads on the bottom, the thickness should be equal to the amount of wear pads circular plate.
(3) bearings and seals, bearings when installing bowl, taking care not to damage the wire rope slinger (physical support between the rope with hardwood, etc.). When assembled, the spherical bearing should be scraping the bowl to ensure the crushing cone and outer contact each other in the inner sphere should ensure that the annular gap 0.35-0.5mm. Nail bowl around the bush with Pakistan-based alloys perfusion fixed bowl bearing shelves to prevent what bowl bearing the circumferential direction of rotation.
Bowl bearing frame and body with the key (pin) fixed, if found in the work bowl bearing frame and body clearance must be treated immediately.
(4) conical bushings, air eccentric shaft sleeve and fit to be strict, in order to prevent the injection of zinc alloy rotating sleeve, zinc alloy to be filled with all the space, due to the reason of zinc alloy thermal injection may cause deformation of the sleeve, so the new set the size of the cone of inspection, found to be incorrect promptly corrected, manufacturing spare parts shall be the actual size of the inside diameter of the eccentric formulated to maintain the original tie.
(5) of the cylindrical body of the bush and the frame for the third transition fit, in order to prevent rotation of the bush, and in the upper part of the tank into the bush zinc alloy, should be replaced with new bushings when the actual size of the frame body preparation, because the crusher after a long work and will inevitably lead to changes in handling relations with. If the gap is too great cause rupture bush.
(6) of the spring, the spring is when the crusher into the not-broken when protecting the crusher is not damaged, so the crushing force of the spring pressure and adapt crusher, crusher spring during normal operation is not moving, just fall crusher iron overload lift support sleeve when the spring is compressed phenomenon occurs in the crushing chamber.

Development History of Impact Crusher

The background of your dates back to the 1850s, The world "initial impact crusher was born in America. Before long, because of the development from the productive forces cannot meet the need of crushing the sugar cane crusher from India; therefore, individuals developed counterattack crusher on the basis of jaw crusher.

In 1924, the German initial developed the single and double rotor two varieties of impact crusher. At that time the crusher of structure is similar to the modern squirrel cage crusher. Simply because no matter from the structure or the work principle evaluation, it has the characteristics in the impact crusher.
For the reason that the material desires repeat impact, the broken might be cost-free or shine inside the process of discharging. But due to the limit of your feeding strength and impact breaker ability, the model progressively transferred into the squirrel cage crusher, applied inside the fining of medium hard.
In 1942, the German Anderson in summarized the squirrel cage crusher’s on the characteristics and working principle foundation and invented the AP series impact crusher, whose structure is comparable towards the present day impact crusher.

Advantage in the larger production effectiveness of this impact crusher and its basic in form structure, convenient to move, so, this impact crusher has created swiftly. In China, the impact crusher development began later. Only within the 1950s, our nation seriously had impact crusher. So, our crushing screening gear was mainly launched in the 50s. started early amongst the domestic impact crusher manufacturer and therefore enjoyed highly reputation in the impact crusher sector.

Routine Maintenance Of the Cone Crusher

Any equipment will be wear and tear occurs with used for a long time, cone crusher is no exception. Because of non-stop work , cone crusher wear time and the material accumulated to a certain extent , there will be some equipment wear, may result in lower yields , or the material is not an ideal situation, then you need to replace the cone crusher accessories.

Therefore , when we use the cone crusher , to regularly carry out regular inspections of equipment, accessories , case can not be used due to cone crusher wear parts , resulting in a greater degree of damage to the machine .

Sanme remind you , cone crusher parts maintenance work is very important , can cause damage to some parts of the machine further damage , and may even unusable. For example, SMS multi-cylinder hydraulic cone crusher, hydraulic system damage if one component is not replaced in time , it may cause the entire hydraulic system is not working properly, it will affect production, but will also bring the loss of interest. In addition , such type of spring cone crusher and so on , but also do inspection, maintenance , especially after a period of time to look at the spring there is no need to replace the gasket .

Cone crusher crushing wall using new composite materials forged a cost-effective , super wear-resistant, wide applications and so on. After a new installation or a new replacement cone crusher wall work six to eight hours , you should check their retention , should be immediately found loose fastening , cone crusher to avoid unnecessary damage .

Cone crusher machine using the machine lies maintenance, so the machine will work for you longer , but your interest is to get the corresponding reward.

best options for processing minerals

There are significant opportunities for the mining and processing of banded magnetite deposits on the African continent. A natural iron-ore deposit is a single deposit with little waste rock mixed into it. With massive iron-ore deposits, the head grade can be 60% to 70%, which means fewer impurities need to be removed before processing the ore into pig iron. The most massive ore bodies consist of hematite, which are the principal and the most stable of the iron oxides. The first step in the comminuting process and liberating a mineral from the ore body begins at the mining stage, with drilling or blasting and excavation used to generate materials that are easily transportable.

Crushers are then used to produce coarse size reduction and grinding mills are used to produce finer particles. As for the crushing process, Sanme crusher is a great option!

The ore mined from massive ore bodies is suitable for use in blast furnaces, they simply need to be crushed into pieces of between 10 mm and 25 mm, and then transported as lumpy ore to iron and steel plants worldwide. The ore is first crushed to size and then passed through a dense media separation process. The dense medium, with a specific gravity of around 3.6 t/m3, is created by mixing water with finely ground ferrosilicon powder. Anything with a specific gravity of less than 3.6 t/m3, for example silica-based rock, which has a density of 2.8 t/m3, will float, while the lumps of hematite iron-ore with a density of around 5.0 t/m3 will sink. What you see coming out of this process are big rocks floating in what looks like black water.

There are several kinds of comminution. In-pit comminution includes blasting, rock breaking and continuous mining; scrubbing, which is used as a polishing agent and not primarily for size reduction; crushing, which includes gyrators, jaw crushers, impactors and mineral screening; and grinding mills, which include the most commonly used semiautogenous grinding (SAG) mills, autogenously grinding (AG) mills, ball mills and rod mills..

Crushed Aggregate for Construction

Crushed aggregate, also known as rock aggregate, refers to a crushed stone product produced in quarries. In areas where natural sand and gravel aggregate deposits are insufficient to handle local demand, larger stones are processed in an impact crusher to create crushed rock aggregate. The Upgraded Version HC Series Impact Crusher from Shanghai Sanme is a great choice for processing such kind of larger stones. The greater costs of production involved in mining and processing the stones to create crushed aggregate mean that the cost of this material is often significantly higher than that of comparable natural products.

All aggregate is divided into two types: fine and coarse. Fine crushed aggregate is broken up into smaller pieces than coarse crushed aggregate. When put through a separator or aggregate washer, coarse crushed aggregate will pass through a 3-inch (7.62-cm) sieve but will not go through a No. 4 sieve. Fine crushed aggregate will pass through a No. 4 sieve but will be stopped by a No. 200 sieve during the aggregate screening process.

The different aggregate sizes and types are appropriate for specific uses in the construction and landscaping industries. For example, although the larger, coarse crushed aggregates are more economical, this type of aggregate can present problems if used in concrete forms for upright structures. By comparison, fine aggregate is suitable for use in concrete, but it would not be a recommended choice for the creation of a roadbed or driveway.

Best Methods for Disposing Construction Waste

There are two methods for disposing construction waste: stationary type and mobile type.

The complete mobile equipment for disposing construction waste includes mobile crushing plant and mobile screening equipment.

The complete stationary equipment for disposing construction waste includes crusher, screening equipment, magnetic separator and necessary transportation equipment.

Process: the construction waste can be divided into two parts by the primary screening equipment. The coarse material should be crushed again, then the magnetic separator help eliminate the lump metal material. Mobile crushing plant adopts professional separation process, for example, we can take the advantage of physical strength and or wet cleaning to make the useful material stay. Such kind of factory may be equipped with sorting device. Such as the bump vibrating equipment can classify and separate the light material such as wood, plastic and paper, etc, as well as the material with light pollution. The crushed material can be divided into inorganic combined aggregate with different purpose and different grain size. For instance, Germany processes the construction waste from the stationary construction waste recycling factory into inorganic aggregate with three level: 0-32mm, 0-45mm, 0-65mm according to the requirements of German standard DIN4226. It can offer the granulate aggregate used for special situation or for special requirements. such as O～8mm, 8～16mm, 16～32mm.

How to Choose a Suitable Crusher

To choose a good and suitable crusher, you need to know what kind of materials you want to crush, size of materials and the output size of stones you want.

Jaw Crusher is widely used in mining, building materials, chemical industry, and metallurgy and so on.

Jaw Crusher Used in Stone Quarrying

Jaw Crusher

Jaw Crusher is a primary crushing machine used for coarse crushing plant in stone quarrying and mine ore mining process. It has properties of large crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, and low cost. So this kind of jaw crusher can be widely used in mining, metallurgy, iron ore, building material, highway, railway, water project, chemical industry, etc, for crushing various materials with compression strength less than 320MPa.
Jaw crushers are equipped with one fixed and one moveable crushing jaw (moving jaw), both of which support crushing plates (wearing parts) in several versions. They form a wedge-shaped crushing zone. The walls of the crushing zone are made of replaceable wearing sheets. Crushing is done between the two crushing jaws. The moving jaw of the single toggle jaw crusher moves elliptically. A pendulum motion is being carried out by the double toggle jaw crusher. Blake jaw crusher is widely used in mining and quarry.
The crushing force is produced by an eccentric shaft. Then it is transferred to the crushing zone via a toggle plate system and supported by the back wall of the housing of the machine. Spring pulling rods keep the whole system in a condition of no positive connection. Centrifugal masses on the eccentric shaft serve as compensation for heavy loads. A flywheel is provided in the form of a pulley. Due to the favorable angle of dip between the crushing jaws, the feeding material can be reduced directly after entering the machine. The final grain size distribution is influenced by both, jaw crusher is the adjustable crusher setting and the suitability of the tooth form selected for the crushing plates. For more details, consult Shanghai Sanme.

Artificial Sand, the Backbone of Construction Industry

Sand Maker

Artificial sand is vital in freeway construction, cement making. The natural sand available in the riverbed is very course and contains very much percentage of silt and clay which reduces the strength of the concrete and hold dampness.
The natural sand has several disadvantages compared to artificial sand. Pulled by the need of expanding domestic demand, infrastructure investment, such as roads, railways etc, is increasing.
Such large engineering project needs lots of high quality sand. However, natural sand is non-renewable resources, with the large-scale exploitation, is increasingly drying up. The natural river sand is the product of sedimentation. Mica, coal, fossils and other organic impurities are present in the river sand. In such a scenario, artificial sand is seen as a welcome alternative to natural sand.
In the process of sand making production, sand maker and crusher equipment is necessary. The raw materials mainly are granite, limestone, basalt, pebbles etc, through a series of crushing and screening equipment in order to reach required level.
Shanghai Sanme can offer a complete solution for sand production. We have the support of german high-tech machinery and full technology. There are two production lines known as dry sand making production line and wet sand making production line.
