Caiman | Crushing | Equipment

Hammer crusher is directly set the maximum size of 600-1800 material crushing to 25 mm or 25 mm for a crusher for crushing. Hammer Crusher applied in cement, chemical, power, metallurgical industries broken medium hardness materials, such as limestone, slag, coke, coal, and other materials in pieces, minor operations. Material can be adjusted in accordance with the requirements, coarse, medium, fine, various specifications are complete; no flakes, no smooth body, multiple number of compressive strength of edges is. Particularly adapted to the highway, construction and large engineering materials. The crushers remove e-break at the beginning of process, a size material at once breaking new models, large output, high efficiency, power, saving resources, reduce the crushing cost of materials.

Hammer Crusher structure:

Box body, rotor hammer crusher, hammer and back lining, sieve plates and so on.

Hammer Crusher features:

• (1) hammer, the introduction of new technology of casting, with wear-resistant, high impact resistance.
• (2) to according to customer requirements, adjust the granularity you want.
• (3) sealed the hammer to break the body structure, solve the crushing workshop of dust pollution and body ash spill problems.
• (4) overall design appearance, compact structure, less wearing parts, convenient maintenance and so on, is the upgraded product.

Advantages of hammer crushers are: as big reduction ratio (usually 10-25, high up to 50), productivity high, uniform product, too little, low energy consumption per unit product, simple structure, equipment light weight, easy to maintain operations.

Disadvantages of hammer crushers are: broken sticky wet material, easy to plug grate slit, can easily cause downtime (water content of a material should not exceed 10%).

Also worth mentioning is the hammer Crusher hammer and grate made of high quality material, reducing the wear of a hammer and grate speed, while she was breaking on hard materials. We have a professional services team, you can reduce the time to overhaul and find balance.

Hammer Crusher working principle:

Hammer type broken machine main is by impact role to broken material of. broken process generally is such of, material entered broken machine in the, suffered to high speed rotary of Hammer of impact and broken, broken has of material, from hammer Department get kinetic energy, from high speed rushed to frame body bezel, sieve section, meanwhile material mutual impact, was repeatedly broken, is less than sieve section of gap of material, from gap in the discharge, individual larger of material, in sieve section Shang again by hammer of impact, grinding, extrusion and broken, material was hammer from gap in the extrusion. to get by required grain of of products.

Hammer Crusher maintenance

• Trouble phenomenon: the spent grain is large.
• Reasons:
• 1) Hammer wear is too large;
• 2) Screen break.
• Troubleshooting:
• 1) Replacing the hammer;
• 2) To replace the sieve.
• Trouble phenomenon: bearing overheating.
• Reasons:
• 1) Insufficient lubricating greases;
• 2) Too much grease;
• 3) To grease dirty metamorphic;
• 4) To bearing damage.
• Troubleshooting:
• 1) To raise the amount of grease
• 2) Run fat should be space in the bearing capacity of 50%.
• 3) Clean bearing grease for replace.
• 4) Replacement of bearings.
• Trouble phenomenon: elastic coupling produces rap.
• Reasons:
• 1) Pin loose;
• 2) Elastic ring wear;
• Troubleshooting:
• 1) Stopping and tighten the nuts of PIN.
• 2) Replace the elastic ring.
• Symptom: the inside of the machine producing rap.
• Reasons:
• 1) The non-breaking into the inside of the machine.
• 2) Liner fastener relaxation, hammer impacting on the liner.
• 3) Hammer or other broken parts. Import pump valve removal method
• 1) Parking, clean up crushing cavity.
• 2) Check the fastening of liner and the gaps between the hammer and screen;
• 3) replacing the broken parts.
