Liming Heavy Industry Symons cone crusher Help

Cone crusher in standard type, short head type, commonly used in fine crushing on.
Standard type, are generally used for the second break, that is broken; short head type are generally used for thin-breaking, that is, the final break.
Symons cone crusher have four cavity. That special coarse type, coarse type, medium, small type. The principle of selection is to look into the nesting material particle size and particle size of the decision to enter Liaodu big, coarse granularity, the election special coarse-type or rough type, and vice versa with medium and fine type. In the calculation of the feed particle size, is the largest open-side feed port size is multiplied by 0.85 as the basis for selection into the size of material, while the average size of the product is the biggest break into the material divided by the ratio.
Symons cone crusher standard used for open-cycle, short head type is used for closed loop.
Liner in the selection, the user must generally take into account three factors: production, power consumption, the wear resistance of lining
In general accordance with the following principles: Maximum feed size; grain size changes, feed particle size distribution; material hardness; material wear resistance.
The longer the higher power liner, hard materials, selected a short liner, soft material selected long liner, in the distribution of materials, thin materials, selected a short liner, coarse material selected long-liners. Feed particle size distribution, in general, smaller than the closed side of the mouth of nesting material should not exceed 10%, if more than 10% of the increase in power consumption, the product size becomes flaky. Viscous material increase in the amount of moisture content of materials can influence the adoption of the amount of moisture on the materials is generally not more than 5%. In the use of power: standard cone crusher should reach 75% ~ 80%, short head cone crusher should reach 80% ~ 85%.
Liming Heavy Industry on the use of standard cone crusher is given the following recommendations:
1, cone break at work, feeding should be uniform, not segregation. If the feed will appear uneven and less productive, the product particle size is too large, spring moves frequently, bowl bearing pressure, power consumption increased.
2, there must be iron removal devices to prevent the crushing chamber had iron, iron if too frequent, it may be broken shaft caused the incident.
3, to full capacity, there would be too coarse granularity.
4, the broken line should be reasonable compared with the distribution, so as to maximize the efficiency of crushing machines.
5, the spring pressure can not be too tight, the pressure is too large an accident will occur off-axis, the pressure is too small spring will often beat, impact crusher work, and the product size thicker.
6, lubricating oil temperature can not be too high or too low, otherwise it will affect the machine running.
7, lubricating oil must be frequently changed, can not be too dirty, dirty gear and bowl speed up the tiles, bushings and other wear and tear, even die sleeve study.
8, the drive belt installation can not be too tight, otherwise it would cause shaft rotation is not flexible or fracture; can not be too loose, otherwise it would cause nausea car crusher.
9, feeding should not be too wet too sticky, not too fine nor too large, otherwise it would cause the stuffy car cone crusher.
10, cone crusher nesting population will also lead to nausea plot mine car.
