Concentrator broken ore crushing equipment often choose what type of ore crushing process in accordance with the practices and crushed product size, the broken equipment crusher and is broadly divided into two categories grinding machine. Crusher for coarse crushing stage, usually feed size product size is also larger and thicker tailings recycling machines, usually (-6mm accounted for 60% or less) 6mm or more. Their basic characteristics are not in contact between the work piece and to maintain a certain gap. According broken way, roughly divided into the following four principles: (1) jaw crushers (also known as the tiger population), it is an ancient, very broad application of broken equipment. Crushing effect is cyclical by movable jaw plate toward and away from the fixed jaw plate. The lump ore crushed between two jaws (to crush mainly) and discharged (by gravity fall), is intermittently broken. According to the movable jaw movement characteristic jaw crusher is divided into simple swing (elbows plate) and re-tilting (single bracket) two. (2) cone crushing machine, is a continuous crushing equipment. According to the mine and product size, cone crushing machine into gyratory cone crushers and the crushing cone crushing machine. According to the length of the crushing chamber is divided into parallel standard, intermediate and short head type cone crushers with B (dynamic cone and fixed cone gap between). Gyratory cone crushers and jaw crushers belong ore crushing equipment, but because of the cone crushing machine continuously, therefore, the same nature when the ore, its production capacity than the much larger jaw crushers. (3) the impact crushers, impact of which is the use of "free" crushing principle to crush ore, ore being repeatedly pad (hammer) and the back plate of the impact and interaction between the ore crushing machine the impact of complex grinding. Therefore, this crushing machine crushing ratio, high efficiency, smashing little, is a promising crushing equipment. (4) roll crushers. Ore from the upper to the two counter-rotating circular roller (smooth or glossy) rooms, by the roller surface friction material was involved crushing chamber is roll crushed ore has been crushed by gravity from between two rollers gap discharge. Mainly used in hard and brittle materials, fine. Electromagnetic vibrating feeder Operation 1, electromagnetic vibrating feeder with the ball supporting device for uniform feed to the ball mill, has the following characteristics: (1) uniform feeding of new tailings recycling machines, production is easy to adjust , easy to implement automatic control. (2) This machine does not have rotating parts, easy maintenance, no lubrication, material parabolic trough earlier jump in advance, hardly trough sliding surface, so wear tiny trough, and use no electric, small reducer tailings recycling machines, due to the above reasons, the unit fuel saving, the use of low maintenance costs. (3) can transport to 300 ° C lower than the burning material. (4) The rugged, small size, light weight, easy installation. Choose Zhengzhou mountains Heavy Industries, electromagnetic vibrating feeder, not only using a ball mill tailings recycling machines grinding equipment, and can effectively improve the efficiency of the entire production line, it is your best choice. 2, before the start electromagnetic vibrating feeder, the amplitude adjustment knob to the minimum position, are sequentially turned switchboard power and control power, and then turn the amplitude knob, gradually the amplitude reaches 7.5mm, then the current rating also reached; or according to the actual situation, adjust the amplitude and the current to the school. After use, the machine allows at rated voltage, start and stop with a load directly. 3, feeder production adjustment, the general can use the following methods: (1) adjusting the inclination of the feeder trough, but does not exceed the maximum inclination -20 °. (2) adjusting the opening of the silo or hopper gate can be uniformly continuously adjusted production. (3) changing the thyristor conduction angle, can be adjusted continuously uniform production. 4, in the feeder during operation shall observe the current stable situation, if found that the current change is greater, must be checked, causing the current reason for the change, generally have the following: (1) a top spring plate screws After long-running loose. (2) spring plate fracture. The gap size (3) between the core and the armature has changed.
