Importance of Hammer Crushing Capacity

Mining crusher refers to the crushing machinery whose content is   more than 50% of the total content, the row compound particle size is greater than three millimeters. It is invented by British Hengan. according to the feeding and nesting size, the crushing operations are often divided into coarse crushing, medium crushing and crushing. The commonly used equipments are impact crusher, compound crusher, single stage hammer crusher, vertical crusher, gyratory crusher, roll crusher machines, double roll crusher, combo crusher, and so on.

Working parts of H-type Universal Vertical roller press grinding is mainly composed of the spindle, trays, the upper grinding rings, grinding balls, grinding ring, pressure ring, pressure spring and the air rings and rails, etc.. The course of their work like a huge thrust bearing, a plurality of grinding balls mounted on the inner raceway ring composed by the vertical mill, grinding ring with the rotation of the spindle and rolling, upper grinding ring does not move, only to bounce up and down, and by the addition of the pressure spring to put pressure on the grinding balls. When the materials form a uniform layer of material from the center of Phan under by centrifugal force into the raceway to discharged by rolling balls crushed under grinding ring, and then be blown by the wind ring on wind hold up into the separator separation . Forming a mixture of gas and powder powder collection to collect complete milling process.

Hammer crusher use the effect of high-speed rotary hammer blow effect to carry out the crushing work . hinged hammer high speed rotary blow gives bulk materials and make the board of the Order of the strike threw the body wall in the Order of the hit board material further impact crusher, fell below the grate bars on the size qualified product discharged from the count gap operator bar materials continue to be hammerhead combat, squeezing or grinding until all seep through until the count bars. When the non-crushing materials mixed hammerhead own concessions and mixed character launched Hammerhead rotation area, so as to avoid damage to the machine, to achieve self-protection role. When the moisture content of the crushed materials is more than 1290, or containing clay, its grate bars slits is easily clogged, thereby reducing the productivity, and increases the wear of parts such as power consumption and hammer itself. Hammer crusher can adjust its product size according to the grate bars lifting mechanism and change grate gap.
