CS symons cone crusher, PY spring cone crusher introduction
Comparing with other kinds crusher, CS Series spring cone crusher with high-efficiency (Symons cone crusher) have excellences for fine crushing, high productions and low maintenance. The long force arm designed into the Symons cone provides greater crushing force.
And the spring release system generates more opposing force than other cone crushers. So use in mine industry widely.
Symons cone crusher is a kind of high efficiency spring cone crusher, which integrate optimization of cavity-type and reasonable stoke and advanced technology, and follows the conception of laminated crushing principle of more crushing and less grinding.
Symons Cone Crusher made plaster stone and engine oil separated, assured reliable performance. The type of crushing chamber depend upon the size of feed and fineness of the crushed product. The standard type is applied to medium crushing, the medium type is applied to medium or fine crushing and the short head is applied to fine crushing. The symons cone crusher has the advantage of reliable construction, high prod activity, easy adjustment and less cost in operation. The spring release system of crusher acts an overload protection system that allows tramp to pass through the crushing chamber without damage to the crusher, use dry oil, water, two kinds of sealed formation.
PY Series Spring Cone Crusher is suitable to crush various kinds of ores and rocks of medium or above medium hardness. Compared with Jaw Crusher, PY Series Spring Cone Crusher is of stable structure, high efficiency, easy adjustment, and economical using etc. The spring safety system of crusher acts as an overloading protection system that allows metals to pass through the crushing chamber so as not to damage the Cone Crusher. The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separated to make sure reliable performance. This type of crushing chamber depends upon the size of feeding and fineness of the crushed product. The standard type (PYB) is applied to medium crushing, the medium type is applied to medium or fine crushing and the short head type is applied to fine crushing.
PY Series Spring Cone Crushercrushes materials by the working surface between the movable cone and fixed cone. So it is more advanced and efficiency than Jaw Crusher. The movable cone is supported by spherical bearing and fixed on an hanging erect shaft which is set in the eccentric sleeve, and the sleeve is set on the stopping and pushing bearing. The movable cone and erect shaft are driven by the eccentric shaft sleeve together. The eccentric shaft sleeve is driven by horizontal shaft and fimbriated gear, and the wheel of the conveyor belt is driven by motor through v-belts. The lower part of vertical shaft is installed in the eccentric sleeve. When the eccentric sleeve rotates, there is a conical surface lined out by the shaft. When the movable cone comes near the fixed cone, rocks are grinded into pieces, when the cone leaves, grinded materials is discharged from the discharge hole. The fixed cone can be ascended or descended by adjusting setting to adjust the width of discharge hole, consequently the output size is determined.

The problem is: A truncated cone is 20cm diameter at the top 30 cm height and L=32cm find the bottom diameter?
any mathematicians out there?
I assume ***L is the slant height***.
If R = radius at bottom, r = radius at top and h = height of the frustum of the right circular cone, then for the truncated cone,
Slant height: L = √[h² + (R - r)²]
32 = √[30² + (R - 10)²]
32² = 30² + (R - 10)²
(R - 10)² = 32² - 30² = 124
(R - 10) = √(124) = +/- 2√31
R = 10 +/- 11.135
R = 21.135 (as R cannot be negative)
So bottom diameter = 2 x 21.135 = 42.27 cm.
Edit:
However, if L = height of the original cone then
r/(L - h) = R/L
[the previous answer made a mistake in the denominator of the right side of the equation; if it has to be 'h' then it will be '(R - r)/h' or else 'R/L']
10/(32 - 30) = R/32
R = 160
Hence, the bottom diameter = 2 x 160 = 320 cm.
