Improvement of cone crusher
Cone Crusher has over 20 years of production in our country's history. In order to improve the productive capacity and operation of medium and fine crushing cone Crusher reliability in recent years, according to production practices of its argument, structures had a greater improvement. Eliminates low spring pressure of the old series, was badly damaged and a series of mechanical problems. Crusher is more complete, and production capacity increased 20-30% of the Crusher.
Recent practical experience based on multi-cylinder hydraulic cone crusher, and hydraulic adjustment of multi-cylinder hydraulic cone crusher, hydraulic locking devices, transplantation into line with the spring cone Crusher. In this way, the current production of spring cone Crusher of hunger, are essentially hydraulic adjustment, hydraulic locking, spring cone Crusher insurance.
Improvement of Crusher specification
Specifications for the crushers originated in the Imperial, past production, 2,100, 1200, 900, cone crusher is the inch size 7 feet, 5 '/: feet, 4 feet and 3 foot of evolution. Of 7 feet and 5 inch '/: feet equivalent and 2,135, 2,100. 1650 than English has reduced and overall dimensions are similar to the inch, so the machine space utilization are not reasonable. In addition, production capacity and fixed cone of the Crusher gang at the end of a diameter of 0 to 2, 5 power relationships grow, so the original capacity of 2,100, is small. More unreasonable is that original useful diameter of 1650 1650, and the lower body due to the internal structure of the limit and had to adopt 1750, it is clear that is a waste. The light of the foregoing, Lieutenant in the new series, 2,100 to 2,200 and 1750 respectively. In the case of shape is essentially the same, more efficient use of the machine's internal space, thereby enhancing the productive capacity of the Crusher.
Improvement of spring pressure
Experience proved that productive capacity of impact crusher, not their discharge capacity, but pressure of insurance of fixed cone spring capacity. The above, the first happens when the crushing hard ore, increased spring pressure than increasing the fixed cone bottom diameter and increase the number of oscillations, but also improve the productive capacity of the Crusher.
Structure and fine crushing cone Crusher insurance spring (also known as lock Springs) is caused by normal crushing force of the necessary equipment and protection when crusher in the iron, unruly; damage to the safety device. Therefore, it is normal when broken, there should be no beating, and iron, it should be flexible.
And fine crushing cone crusher, crushing ore crushing force required, crushing strength formula of the theory of exact ore sought is extremely difficult, so the average is determined according to Crusher practical work experience spring pressure. Spring pressure determine right or wrong, use of crusher and manufacturing costs are directly related. Spring pressure is too small will result in Crusher does not work (low yields, size through the thick and mechanical damage to critical). Instead, spring pressure is too large will result in higher manufacturing costs (improved materials and increased machine). As ore strength varied greatly, preferably one for ore, define a suitable spring pressure.
