Jaw crusher specification how to represent? The largest block of feeding and its specifications are what? Jaw crusher feed size is the width B and length L to represent. For example, 900 × 1200 mm jaw crusher represents it to the mine mouth width of 900 mm and a length of 1200 mm. According jaw crusher feed opening width can be divided into large, medium and small three types. Feed opening width greater than 600 mm are large, feed opening width of 300 to 600 mm are for the medium, feeding mouth width of less than 300 mm are small-scale. Production for the jaw crusher to the ore block of maximum feed opening width B than the small 15 to 20%, the largest block of feeding the largest D = 0.85 ~ 0.8B. Structure and working principle of jaw crusher is what? Common jaw crusher, there are two: the upper and lower movable type movable type. The movable jaw crusher discharge opening width due to the constant, often occur clogging work, roll crusher, affecting the normal work. So now it has been eliminated. By moving jaw crusher concentrator with most. Jaw crusher is composed of the following main components: a fixed jaw plate is a rack of the front wall, hanging in the shaft of the movable jaw, eccentric shaft, vertical rod, brackets, flywheel drive, two jaw plates lining, rod with a spring bracket seat adjustment block. Jaw crusher working principle: the motor through a belt when the eccentric shaft is rotated upward and downward movement of the vertical rod that is, when the vertical rod upward, driven by two brackets gradually stretched flat, forcing bracket fixed to the movable jaw plate jaw forward, roll crusher, crushing chamber (that is, from the amount of the fixed jaw plate and moving composition space) ore squeezed, split, folding flexor role of fragmentation. Downward movement of the vertical rod, toggle plate and movable jaw plate by the force of the spring and the rod of the back, this time the port of discharge increases, thereby discharging the crushed ore. Visible time off jaw crusher broken ore. The eccentric shaft is only half a turn per cycle for crushing, followed by a half cycle for discharging mine. So it is compared with other continuous crushing machinery, power-hungry, low mechanical efficiency. People if long-term inactivity will lead to decline in physical function, muscle contraction, feel powerless again when you want to be active. The same is also true crusher. Crusher is a lot of our work indispensable, hammer crusher crushing machine is a high-speed rotation. Some work without it there is no way to work, so we use the time we should know know it's maintenance, Liaoyang crusher, hammer crusher is how to operate and maintain it? (1) To empty start, pay attention to the crushing chamber should be emptied before the material down. (2) to be associated with the machine on, the next step before the open parking made contact, according to the order open parking for proper operation. (3) maintaining uniform feeding, and care not to feed the metal debris. (4) regularly examine the use of hammer, liner, and so easy to wear and easy wearing parts, if they are found promptly. (5) pay attention to check the height of the expected size meets the quality requirements, such as not, should be replaced or adjusted grate grate bracket. (6) regular checks of all equipment anchor bolts, liner bolts, loose, if loose, roll crusher, should be tightened. (7) should always look at lubrication, lubrication system in good condition. Rotor bearing temperature should be kept below 60 ℃, the maximum does not exceed 70 ℃, if found overtemperature reasons should be identified, to take timely measures to eliminate.
