Jaw crusher is widely used in metallurgy, building materials, chemicals, coal and other industrial sectors, in return for material handling prebaked anode production process. The aircraft used for a variety of materials Mohs hardness below 7 coarse, medium, fine, when used in crushing, the appropriate choice of fine jaw crusher. Jaw crusher hungry applicable materials are pyrite stone, phosphorus ore, barite, celestite, calcium carbide, coke, limestone, etc., should not be used pieces of broken ore. On the use of jaw crusher production process, should set the device to control the feed rate and pre-screening and screening checks can make uniform particle size, over crushed reduce and improve the quality of the crushed product. Jaw crusher is used for crushing medium hardness (Platts hardness factor of 4 or so) and brittle rocks lining for rib shape, the angle between the ribs for 90 ° ~ 100 °; and quite stiff when broken Hard (Platts hardness coefficient 5 ~ lO) when materials, linings for wavy edge strip; when crushing hard and very hard (Platts hardness factor of 10 to 18) of material, the liner should be widely spaced The ribs, the lining of the edge width ratio t h of the edge of the high t / h≈2 ~ 3. When you select the type of crusher, first by a maximum feed size to choose, if the production of a crushing jaw crusher can meet your needs, you should choose to use jaw crusher. Usually less than 5501 / h in production, tend to choose jaw crusher; in, fine, the same choice of jaw crusher when a small amount of production. I plant jaw crusher has the following characteristics: 1, the crushing chamber deep and no dead zone, improve the ability to feed and production. 2, the crushing ratio, uniform particle size. 3. Gasketed nesting population adjustment device, reliable and convenient, large adjustment range, increase the flexibility of the device. 4, the lubrication system is safe and reliable, easy to replace parts, equipment maintenance is simple. 5, simple structure, reliable operation and low operating costs. 6, energy-saving equipment: single energy saving of 15% to 30%, more than double the energy saving system. 7, the discharge opening adjustment range, can meet different user requirements. 7, low noise, less dust.
