Cone crusher is widely applied in metallurgical, construction, road building, chemical and phosphatic industry. Cone crusher is suitable for hard and mid-hard rocks and ores, such as iron ores, copper ores, limestone, quartz, granite, gritstone, etc.the following is features and advantages of sand making machine about cone crusher.
1) along the inner surface of the weakest material crushing, generally ore mainly exist in nature with irregular crystals form, vibrating cone crusher of these crystals along the interface or internal defects broken, effectively eliminating the defects, the maximum to maintain the original shape of the crystal. River sand for building use can not meet this requirement, artificial sand solve the shortage of natural sand, impact crushers are used in the past. Generally eccentric cone crusher, rod mill can not remove defects of sand, and some even can not guarantee the basic shape, and to use vibrating crusher, and strictly control the size of its crushing force, can produce multi-grain level, isometric, and small defect particles significantly increased the building strength; Crushing ratio can be more than 30, it is adjustable in the range of 4 to 30, and can reduce the material to be over crushed.
(2) When the discharge gap increases (such as hammer lining wear and tear) will not increase the average particle size of broken products;It can start and stop with a load.
(3) When the foreign body can not be broken into the crushing chamber, the drive will not cause overload or damage;It can reduce the number of broken segments: simplify processes, reduce the number of auxiliary equipment.
(4) Without dosing unit to the crusher feed;It do not need heavy foundation structures, can reduce the construction investment of 20 to 30%.
(5) It can be more dynamic hammer beat frequency, increase production and break ratio.;Using a reference oscillator quality, eccentric plasmid, much resonance, consisting of flexible system can achieve sub-resonance, near resonance, much resonance to design the vibration mode shapes of different cone crusher.
(6)It has no inertia cone crusher spherical plain bearings, so that manufacturing becomes very simple, the same size with lower price;Crusher is easy to adjust. Crusher operation for some time, such as nesting size changes, and perhaps adjust the marker size, adjust the angle between the main and eccentric block, when a = 0 °, the breaking force can be maximum.
Pay More Attention to Installation of Ball Mill
The installation of ball mill was finished and passing test, it can do operation without loading materials. The test operation of ball mill shall be responsible by skilled operator and strictly abide by safety operation specification of ball mill.
Pay more attention to the following cases:
1. The continuous running time of energy saving ball mill should not less than 12-24 hours and also timely solve the problem that was funded in operation process. If the running without loading materials is normal, just then, it may do loading running. The loading running should do in different stage. Feeding should on the basis of the discharging situation in the process of loading running, avoiding unnecessary wear down and damage.
2. Add appropriate materials and 1/3 of steel ball, then, do test operation for 12-24 hours.
3. Do test operation for 24-48 hours with 2/3 of steel ball.
According to the discharging situation of energy saving ball mill, the output of accepted products and the number of actual steel ball should refer to the similar beneficiation factory, thus, make reasonably steel ball of this ball mill sure and do test running for more than 72 hours.
As far as the increase of loading capacity and time of test running, it was can be determined according to the situation(temperature, noise, gear surface contact, etc) of the different size gear and reduction gear. The touch between gears didn’t meet design requirement, under the circumstances, it can’t do loading running test.
What’s more, it is should be ensured that cooling system, lubrication system can work normally, and the temperature of main bearing, driving bearing, reduction gear should normal in the test running of energy saving ball mill.
