Cone crusher routine maintenance 1, to full production, there would be too coarse granularity. 2, the production line of broken than allocated to a reasonable amount of money Raymond mill, so as to maximize the efficiency of the crusher. 3, to have iron device to prevent the crushing chamber through iron, iron if too frequently, it may cause broken shaft accident. 4, the spring pressure is not too tight, too much pressure will be broken shaft accident occurred Raymond mill model, the pressure is too small springs frequently beat Raymond mill, impact crusher work, and coarse granularity. Hammer crusher with crushing ratio, high production capacity, uniform particle size and other characteristics, the crusher is metallurgy, building materials, chemicals and utilities and other industrial sectors crushing limestone, coal or other major equipment of medium hardness of less brittle materials One. Hammer crusher is the use of high-speed impact of hammerhead role of materials broken machinery broken and minor operations. Hammerhead hinged on the high-speed rotation of the rotor, the lower part of the body to control the grate nesting size. Material into the crusher by high-speed movement of the first impact of the initial hammerhead broken, and also get the momentum Raymond mill manufacturer, high speed toward the inner wall of the chassis and broken plate again been broken. Less than grate gap material is discharged outside the machine, more than grate gap slug impact on the grate and grind hammer again, until less than grate of the gap after being discharged. Raymond mill manufacturer, Raymond mill, the machine is provided by Lei Lei Machinery Co., Ltd. Zhengzhou. Zhengzhou Lei Machinery Co., Ltd. (www.hnzljx.net) (www.hnzljx.net) strong, credible, in Zhengzhou, Henan crushing grinding equipment industry has accumulated a large number of loyal customers.
