New ore crusher and its main types

2017-04-28

Although there are many types of crushing machine, but according to the different methods of force, the material crushing, extrusion, bending, impact, shear and Raymond Mill. In the crushing machine, the force situation is very complex, often there are several forces exist, of course, there is only one or two major forces in a broken machine.
Because the shape of the material particle is irregular, and the material property of the material is different, the grinding method is also different:
1 the material is placed between the two working faces, and the material is crushed by the compressive stress when the pressure is applied.
2 the material will be placed in a plane and a working surface with a sharp edge. When the working surface with a sharp edge is extruded from the material, the material will be split along the direction of the pressure line. The reason is that the tensile stress on the splitting plane reaches or exceeds the tensile strength limit of the material. The tensile strength of material is much smaller than that of compressive strength
70 percent off broken material is subjected to bending stress. Two point supported simply supported beam or multi support beam subjected to concentrated load. When the bending stress of the material reaches the bending strength of the material, it is broken and broken.
4 impact crushing material by the impact force and broken, because of its crushing force is instantaneous action, the crushing efficiency is high, Impact Crusher, energy consumption is less, the impact of the following are broken:
(1) the impact of moving objects on materials
(2) the impact of high speed moving materials to fixed working face
(3) the impact of high-speed movement of materials
(4) the high speed moving body impacts the suspended material
5 grinding (grinding)
Under certain pressure and shear forces between surfaces of material and motion, shear strength limit of the shear stress to the material, the material is crushed, or between each other, when the shear friction material and the material crushing grinding effect.
Main types of crushing machinery
1 according to the structure and the working principle of the different commonly used crusher has the following types
(1) Jaw crusher is to rely on the movable jaw plate for periodic reciprocating movement, the material into the two jaw plate crushed.
(2) the impact of the hammer crusher Material by the high-speed rotation of the hammer and the material itself to the impact of the high speed of the impact of the fixed liner.
(3) the eccentric rotation of the cone crusher (gyratory crusher) is caused by the eccentric rotation of the inner cone so that the material between the two cones is bent and crushed
(4) the impact of the crusher Material by the high-speed movement of the hammer hit, so that the impact of the material to the high-speed impact plate, as well as the collision between the material and broken.
(5) the material of the roller crusher falls on the rollers which are parallel to each other and opposite to each other (opposite direction), and the material is pulled into the rotary roller under the action of the friction force of the roller surface, and is crushed by the extrusion of the roller.

MB crusher company’s other advantages have introduced a new BF90.3 crushing bucket, the feed width of 900mm, jaw adjustment of 20 ~ 120mm. In order to provide support to users, the company also set up MB after-sales service The “With this dedicated department, our service technician can fly to any part of the world to solve all the technical problems that big users are experiencing.” In 2009, Auru launched a technology for 16 to 45t Excavators and large wheel loaders used on the D series siege bucket. The six-size sieving bucket specifications range from 15mm to 100mm. “The biggest advantage of the D-Series is that it can handle other sieving Vanguard crusher ohnson crusher The new KPI-JCI brand model is the highest in the crusher in the production capacity of the model, according to the company said that its production per hour than the traditional crusher to 25% higher.
The key to this model is the H2550’s unique hydraulic rocker system, which is equipped with heavy hydraulic cylinders that can be designed specifically for the user’s crushing requirements. This innovative hydraulic adjustment, unloading and clearance method can reduce the time of failure and prevent damage to parts. At the same time, it protects workers from the risk of injury. These hazards are generally related to the operation and maintenance of the old jaw crusher. The H2550 is a low profile design with a leg mounted on the waist of the machine. The hollow frame not only reduces the total weight of the machine, but also provides excellent strength and durability. Its inlet opening is 625mm × 1250mm, jaw template can be replaced and can be installed, equipped with a protective link with the replaceable rocker head and impact plate.
We want to let the user on the site can handle these past can not handle the material. The current economic environment requires more efficient, so A Lu to develop efficient products. Mr. Maclynn explained that the main purpose of developing the D-Series was to provide a one-stop service for the builders to enable them to process and recycle all the excavated materials on the site and reduce the use of new materials, thereby reducing the amount of waste and Reduce landfill costs. “The working principle of the D-Series is mandatory screening, which is more advantageous than gravity screening,” he continued. “Because it can sieve the wet material before the Jaw crusher, the traditional crushing system is an improvement.” With the times in 2010 for the builders, the biggest change is the industry’s manufacturers to provide Of the service increased, whether in the product or in the after-sales service. “In the past, users were only concerned about the aftermarket service,” said SimonPelletier, senior vice president of aftermarket at Metso Mines. “Now, users are very interested in long-term contracts and are tightly linked to suppliers For a full range of support from the manufacturer’s technology, application expertise and full life cycle service. “Metso Mining has launched a series of machine protection programs that allow all important components on the user’s machine Extended warranty period.

ultra fine grinding mill grinding effect

2017-04-24

The principle of ultra fine grinding mill and fine grading mainly includes the particle size, grain property and characterization method of ultrafine powder, the deformation and crushing mechanism of the fine particles, the kinetics and mathematical model of the crushing process, The material is not in the crushing method, equipment and not to the crushing conditions and crushing environment energy consumption law, crushing efficiency and energy utilization, not to the mechanical stress of the way and equipment in the case of grinding to the crushed material crystal Structural and physical and chemical properties (ie mechanics of the pulverization process), grinding aids, dispersants and the like, and the effects of the physical and chemical environment on the product’s sewing, physical and chemical properties, crushing efficiency and capacity utilization.
Ultrafine powder particle size, particle size characteristics and characterization methods, crushing process of the mechanical principle and the general powder has many and to the place.
The ultrafine pulverization process is not only a process of particle size reduction, but also when the material is pulverized by mechanical force, accompanied by the change in the grain structure and the physical and chemical properties of the material to be pulverized. This change is negligible for the relatively coarse pulverization process, but for the ultrafine pulverization process, the pulverization time is long, the crushing strength is large and the particle size of the material is pulverized to micron or less Under certain crushing processes and conditions. This change in the crystal structure and physicochemical properties of the pulverized material caused by the mechanical superfine pulverization is called the mechanical or mechanical chemical effect of the pulverization process. This mechanical and chemical effect on the performance of the material to be crushed to a certain extent, is purposefully applied to the powder material surface activation treatment.
The mechanical and chemical changes in the pulverization process include:
Activated by the rearrangement of the atomic structure of the material and heavy fiber crystal, the surface layer of spontaneous reorganization, the formation of non-quality structure.
The foreign molecules (gases, vapors, surface active parts, etc.) spontaneously carry out physical adsorption and chemical adsorption on the newly generated surface.
The chemical composition of the material being pulverized, and the interaction between the particles and the chemical reaction.
The physical properties of the material to be pulverized.
These changes are not in all the crushing operations are expected to exist, it is with the mechanical force of the way, crushing time, crushing environment and the type of material to be crushed, grain, materialized but qualitative and so on. Studies have shown that only the ultra-fine grinding or ultra-fine grinding process, the above mechanical chemical phenomenon will be significant or detected. This is the ultra-fine grinding is the unit smash the product can be a high operation, the mechanical force of the role of strength, material research time is long, the material surface area is large, the surface is high. In this regard, the following discussion of the process of ultra-crushing process of chemical phenomenon.
In the process of ultra fine grinding mill, due to the strong and lasting mechanical force, the powder material does not occur to the extent of character distortion, grain size becomes smaller, the structure of disorder, the surface of the formation of amorphous or amorphous substances, Polycrystalline conversion occurs. These changes can be detected by x-ray diffraction, infrared spectroscopy, nuclear magnetic resonance, electron paramagnetic resonance, and differential thermal apparatus.
The reactivity of the calcium hydroxide material can be enhanced by fine grinding, which is very important in the construction of the building materials. There is not enough inertia or activity to these materials for hydration. In the process of ultra fine grinding mill, when the particle size is reduced to micron level, the particles of the placard tends to be uniform, the defect is reduced, the strength and the hardness increase, the grinding difficulty is greatly increased. The ratio of surface area and surface energy increased significantly, and the tendency of the fine particles to agglomerate (to form secondary or tertiary particles) was significantly enhanced. For the wet pulverization, the lice degree of the ore was significantly increased. The mobility of the oars is significantly worse. If you do not take a certain process measures, then the crushing efficiency will be significantly reduced, the energy consumption per unit of product will be significantly improved, which is in the process of mixing crushing material must be good dispersion and in some cases the use of dispersants or grinding The background of the agent.
Abrasive is a class of chemicals that can significantly improve the efficiency of ultra fine grinding mill operations or reduce the energy consumption per unit of product. It includes organic and inorganic substances that do not state (solid, liquid and gaseous). The main purpose of adding a grinding aid is to improve the grinding of the material, to prevent the melting of micro-particles, agglomeration and adhesion in the mill liner and grinding media to improve the flow of material within the mill, thereby enhancing the product Fineness and sewing products to reduce the crushing limit and energy consumption per unit of product. Obviously, the dispersant is also a grinding aid, it is by preventing the agglomeration of particles, reducing the oars to play the role of grinding.

How to eliminate these so-called & other; Question & throughout; , small make up for this sums up the following & other; Question & throughout; :
1, work clang, lining board jitter. This phenomenon is due to the crushing cavity side plate and more loose tooth plate (,), tighten the screw loose or rupture caused by, should tighten or replace in a timely manner.
2, after knee fracture frequently. After bracket in addition to the transmission power is depend on the strength of the shortage of the insurance. In addition to the central bracket intensity is low, its strength is not enough to overcome damage due to normal crushing force produced by crushing ore, may be too tightly on the lever spring, coupled with crushing force at work overload and fracture, can adjust appropriately loose spring.
3, crusher run idle, lower metal sound. The possible causes of has the following three aspects: (1) broken mobile jaw and fixed jaw teeth board sound, is caused by row ore mouth is too small. Plate (2) the thrust bearing or gasket in adjusting device in the crash, general is due to the pull rod buffer spring elastic disappear or damaged, or rotational spring pressure is not tight. (3) it is also possible that bracket bearing slider wear serious or relaxation, the bracket head wear.
4, flywheel swing dramatically, eccentric shaft rotation is slow. The fault system as part of the pulley and the flywheel key loose or damaged, can”t synchronous wheel and axle.
5, broken product granularity coarsens, this is the result of severe wear of broken plate bottom. Tooth plate should be up and down a transfer or replace a new lining board, adjust the row ore mouth to reach the requirements of the size.
6, the flywheel Quarry Crusher does not work. Reason is due to the damage of tie rod spring and pull rod, tie rod nut tripping bracket from bearing slider pull, can also be bracket broke off, and should be replaced to install.
