The hammer crusher(hammer mill) crushes by the collisions between high-speed hammer and materiasl, and the hammer crusher(hammer mill) features are in its simple structure, high reduction ration, high efficiency, etc. The PC hammer crusher(hammer mill) were developed for both dry and wet crushing of brittle, medium-hard materials for the mining, cement, coal, metallurgic, construction material, road building, and petroleum & chemical industries.

Operating principle of Hammer Crusher

T he motor drives the rotor rotate of the hammer crusher at a high speed through the belt, and on the rotor there are series hammers. When the materials get into the working area of hammers, they are crushed by the rotating hammers of the hammer crusher with high rotation speed, the products which are crushed to meet the required size can be discharged by the outlet and become the final products, the large size products are brought back to the crushed area by the hammers of the hammer crusher for being recrushed until they reached the required size.

Working Principle Of Hammer Crusher

The electric motor drives the rotor, and the rotor moves and makes the hammer board rotate faster. The materials are crushed in the crusher by the rotated hammer board. The end products come out via the strips of the screen under the machine. The size of the granularity can be adjusted by changing the distances among the screen strips.

Features Of The Hammer Crusher

1.simple in operating
2. high in productivity
3.very low investment cost.

Filed under: Uncategorized — Tags: , , , , — sbmzhcn @ 11:10 am

Ball Mill  is an efficient tool for grinding many materials into fine powder. Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry way and the wet way. It can be divided into tabular type and flowing type according to different expelling mine. To use the Ball Mill, the material to be ground is loaded into the Neoprene barrel that contains grinding media. As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours.
Quite simply, the longer the Ball Mill runs, the finer the powder will be. Ultimate particle size depends entirely on how hard the material you’re grinding is, and the time how long the Ball Mill runs. Our Ball Mills have been used to grind glass, powder food products, create custom varnishes, make ceramic glaze, powder various chemicals, and make Black Powder.

crusher machine and stone crusher

Lithotripter(crusher )is the exclusive compound content of particles larger than 3 mm of the total emission rate 50% or more of the crushing machine. Operations often broken by feeding and nesting into coarse grain size of the broken, the broken and petty. Gravel equipment commonly used jaw crusher, jaw crusher, impact crusher, impact crusher, compound crusher, single-stage hammer crusher, vertical crusher, gyratory crusher, cone crusher machine, roll crusher, double roll crusher, combo breaker, a molding machine broken several.

Jaw Crusher jaw plate on the use of two materials extrusion and bending and breaking all kinds of coarse broken or hardness of the material in the crushing machine. The broken body from the fixed jaw plate and movable jaw plates, jaw plates close to the time when the two materials Jibei broken jaw plate away when the two nesting population is less than block from the bottom of the discharged material. It’s crushing action is carried out intermittently. This crusher due to simple structure, reliable and can be broken advantages of hard materials are widely used in mineral processing, construction materials, silicate and ceramics industries.

80 to 20 of the 20th century, 800 tons of material per hour, breaking a large jaw crusher to a particle size has reached approximately 1,800 mm. Commonly used jaw crusher with elbow board and two single brackets. The former moving jaw at work only a simple swing arc, so called simple swing jaw crusher; the latter for the swing arc to move up and down also, so called complex swing jaw crusher. Jaw Crusher widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and other sectors, breaking strength no more than 320 MPa of various materials.

Single-plate jaw broken elbow mobile jaw plate up and down movement to promote the role of nesting, and its level of travel is greater than the upper part of the lower part of bulk materials easily broken, so the broken above the elbow plate efficiency. The disadvantage is that jaw plate wear faster, and the materials have been smashing the spontaneous increase in energy consumption. In order to protect the important parts of the machine is not damaged due to overload, and often the shape of the small size of the brackets designed for weak links, overload the machine when it first deformation or fracture.

In addition, to meet the requirements of different marker size and compensation jaw plate wear and tear, but also the addition of nesting population adjustment device, usually in brackets after the frame between the seat and adjust the pads or radiotherapy, wedge. However, in order to avoid damage to replace broken parts to affect production, but also can be used hydraulic equipment to achieve security and adjustment. Some jaw crusher also has a direct hydraulic drive to drive fixed jaw plate, to complete the materials in the crushing action. These two types of hydraulic transmission equipment jaw crusher, often referred to as hydraulic jaw crusher.

Gyrating crusher cone crusher is used in the shell cavity of the cycle within the cone movement of materials generated extrusion, splitting and bending and hardness of coarse broken all kinds of large-scale ore or rock crushing machinery. Broken cone axis with the upper bearing bush in the middle of the beam, the lower end of the eccentric sleeve is placed in the hole. Sleeve rotates around the broken cone axis for eccentric cycle exercise machine of its crushing action is continuous, and therefore the efficiency of higher than jaw crusher. To the early 70s, large gyratory crusher has been able to handle material per hour, 5,000 tons, the largest feeding up to 2,000 mm diameter.

Gyratory Crusher two ways to achieve nesting population adjustment and overload insurance: the first is using mechanical means, the spindle nut to adjust the top, rotate adjusting nut, cone can be broken down or up, so I followed changes nesting bigger or smaller, overloaded, by cutting off the pin on the drive pulley to achieve insurance; The second way is to use hydraulic breakers hydraulic cycle, the spindle is located in the hydraulic cylinder of the plunger, the change under the plunger hydraulic oil can change the volume up and down the cone crusher location, thus changing the nesting population size. Overload, the spindle downward pressure to force the plunger into the hydraulic oil under the accumulator in the hydraulic system so broken down cone to increase the nesting along the mouth of material discharged into the crushing chamber with a non-broken materials (iron, wood, etc.) in order to achieve security.

Cone crusher crusher working principle and the same cycle, but only in the crushed or broken mechanical crushing operations. In nesting crushing operations than the general uniformity of size pieces operational requirements of the high rough, so the lower part of the crushing chamber shall be a parallel to the area, while also speeding up the cycle speed cone crusher for material in the parallel area squeezed by more than one within.

Comparison of crushing operations in the crushing operation of a large coarse broken, so broken loose of its larger volume have increased. To prevent the crushing chamber may give rise to obstruction, without increasing nesting population to ensure that the necessary premise of size marker to be broken by increasing the diameter of the bottom cone to increase the total cross section marker.

Cone Crusher nesting population smaller, mixed with a compound of the non-broken things easier cause of the accident, and because, the crushing operation on the marker size demanding to be adjusted in the liner wear in time after the nesting population, which tapered Crusher insurance and adjusting device is more necessary than the primary crushing operations.

Symons cone crusher overload the insurance, the conical shell to force the compression spring to increase their own in order to increase the nesting population, and expel non-broken material. Nesting population set to be adjusted by adjusting, turn the adjustment sleeve solid shell can be filled with the help of the cylindrical shell on the thread to bring up or down to change the nesting population size. Hydraulic Cone Crusher way of insurance and adjustment of the same Hydraulic Gyratory Crusher.

Roll crusher is to use the friction of the roll surface to bite into the broken areas of materials, so bear squeeze or split and broken machinery. When broken or needs to be increased for coarse crushing ratio, often made in the roll surface of the teeth or grooves to increase the splitting effect. Roll crusher is usually divided by the number of roller single roll, double roll and multi-roller crusher, suitable for primary crushing, breaking or crushing of coal, limestone, cement clinker and stone in the long and soft materials.

Hammer crusher is to use high-speed impact hammer effect on the material for the broken and broken mechanical crushing operations. Articulated high-speed rotating hammer rotor, the lower body with grate bars to control the size marker. First of all the materials into the crusher by the high-speed movement of the hammer impact and the initial break, and also get the kinetic energy, high-speed flying broken plate on the casing wall being broken again. Smaller than the gap of the material grate bars are from outside, is larger than expected gap grate bars in the grate bars on the block again, the impact and grinding by the hammer, until the gap is less than grate bars after being discharged.

Hammer crusher with crushing ratio, uniform particle size marker, less than smashing things, lower energy consumption. However, hammer wear faster, the hard crushing of the applications was limited; another plug because fear of grate bars, not in Congress and the humidity with it crus
hing materials with clay. This crusher is usually used for crushing limestone, shale, coal, gypsum, chalk and other materials in the brittle and soft.

The hammer crusher hammer for the steel ring of the ring coal crusher, hammer crusher is a variant. It uses high-speed impact and the combination of low-speed rolling to break material, and thus obtain more detailed product, mainly used for the crushing of coal power plants, but can also be used for gypsum, salt, chemicals and some crushing of hard materials.
Impact Crusher is the use of panels of high-speed impact hammer rebound effect and the counter plate so that the impact of material broken by repeated mechanical. Hammer solid plate installed in the high-speed rotation of the rotor, and along the crushing chamber by a number of different angles, block counter board layout.

Materials into the role of zone plate hammer by the board before the first hammer impact and the initial break, and also get the kinetic energy, high-speed counter board rushed. Plate collision with the counter material broken again, bounced back to hammer the role of board area, by the board to re-hammer impact. Is repeated until it is broken into the required size and discharged outside the machine. Compared with the hammer crusher, impact crusher broken than the larger and more fully utilize the high-speed impact energy throughout the rotor. However, as easily wear plate hammer, it shattered in the application of hard materials is restricted, often used to rough broken, in pieces or crushing limestone, coal, calcium carbide, quartz, dolomite, iron pyrites, gypsum and chemical raw materials so in the hard-brittle materials below.

Ring hammer crusher main purposes:
The series of hammer crusher is suitable for crushing all kinds of brittle materials, such as coal, coal Chin, coke, slag, shale, loose limestone. The compressive strength of materials, not more than 10MPa, the surface water is not more than 8%.
Winnowing hammer crusher used in construction materials, brick, coal, metallurgy, mining, power, light industry and other industrial sectors, for crushing coal, shale, coal, carbon, lime, cement guessed, Peng Yun-soil and in hard-brittle materials.
Described above, several gravel sand production line equipment and production line stone crusher equipment is essential.
Jaw crusher for cement, coal preparation, power generation and building materials to meet the crushing medium hard and brittle materials such as limestone and coal. Maximum compressive strength of not more than 1500kg/cm2.
