Hammer crusher - hammer negative experience
Hammer crusher or hammer mill overview
Single-stage hammer crusher broken equipment commonly used in the limestone. With than the traditional add-e crusher counterattack crusher stone crusher machine two advantages.
Hammer crusher wear and tear of large, life is short, use good material production of the hammer crusher effect is not obvious. The statistics, power 8 to 10 hours a day, each hammer (36) can use up to 10 days, this period can be broken limestone 35,000 to 4 million tons. This calculation, the monthly change at least two sets of hammers. Hammerhead annual funding for the replacement of 120 million, resulting in tremendous waste.
Technicians use their brains for technology research, hammer crusher should be made early use of upside down, that is when the hammer began to wear upside down installation, use about 4 days later, another surface wear flip installation again, the cycle Use upside down several times, a hammer can greatly extend the usage time.
After testing of raw materials plant maintenance personnel, upside down early hammer crusher used a hammer more than 60,000 tons of limestone can be broken, to extend its life nearly 1 times than before. Despite the heavy workload hammer upside down, but you can take advantage of down time during the day, which does not affect production, but can also be symmetrical each side change turned 1 / 3 of the hammer.
Now less effective because of the excessive wear and tear before hammer caused by upside down, so time to grasp the importance of hammer upside down. (Raw materials crusher).
Hammer crusher for crushing all kinds of hard and abrasive weak materials. The compressive strength of the material does not exceed 100MPa, water content less than 15%. Material to be broken coal, salt, chalk, gypsum, brick, limestone and so on. Also used broken fiber structure, strong flexibility and toughness of broken wood, paper or broken asbestos cement waste to recover asbestos fibers and so on.
Hammer Crusher is the main working parts with a hammer (also known as hammer) of the rotor. Rotor from the spindle, disk, composed of pin and hammer. Cavity in the broken rotor motor driven high-speed rotation. Material from the upper mouth to feed into the machine, by the high velocity hammer blow, impact, shear, abrasive and grinding. The lower part of the rotor, with sieve plate, crushing the material in grain size smaller than mesh size sieve discharged through the larger than coarse mesh size in the sieve retention continue to be a hammer blow on and grinding, and finally through the sieve plate from the plane.
Hammer mill is the use of high-speed impact hammer effect on the material for crushing operations in the broken and broken machinery. Articulated high-speed rotating hammer rotor, with the lower body to control the discharge grate size. First of all the materials into the crusher by the high velocity impact of the initial crushing hammer, and also gain kinetic energy, high-speed toward the wall on the case has again been broken plates and broken. Grate the material is less than the gap from the plane was larger than expected gap grate in the grate on the block again, the impact and grinding by the hammer until the gap is less than grate after discharge.
Hammer crusher with crushing ratio, discharge uniform size, less than smashing things, lower energy consumption. However, due to wear faster hammer, broken in the hard material has been limited application; also afraid of the grate block, not in the humidity with it crushing the clay-containing materials. This crusher is usually used to broken limestone, shale, coal, gypsum, chalk and other materials in the hard brittle below. The hammer crusher hammer for the steel ring ring hammer crusher, hammer crusher is a variant. It uses high-speed impact and the combined effects of low-speed rolling to broken materials, and thus obtain more fine products, mainly used for crushing coal for power plants, but can also be used for gypsum, salt, chemicals and some crushing of hard materials.
