Cone crusher is widely used in mining industry, metallurgy industry,
construction, road building, chemistry plant and silicate industry. It is used
to break hard stone and rocks, such as iron ore, copper ore, quartz, granite,
limestone, sandstone, etc.
Cone crushers fall into coarse crushing cone
crusher, medium crushing cone crusher and fine crushing cone crusher, all of
which is available for ore rocks above middle hardness.
PY series cone
crusher
PY series cone crusher is available for ore rocks above middle
hardness. Crushing chamber shape is decided by purpose of finished ore products.
Among of them, standard crushing chamber is fit for medium crushing; Medium
chamber is fit for medium and fine crushing; Short head is suit for fine
crushing.
Points for attention in operation
1. As for PY series cone
crusher, the crushing ratio of medium and fine crushing is larger than coarse
crushing. In order to prevent crushing chamber from bogging, we should increase
discharging open and guarantee the particle size. On the other hand, we should
also increase diameter of the bottom of cone to enlarge cross section of
discharging open.
2. Since the discharging open of PY cone crusher is small,
the foreign material is likely to cause accidents. Besides, medium and fine
crushing is highly required in particle size. We must adjust discharging open
timely once liner has worn. Therefore, the cone crusher fool proof device and
adjusting device is more important than coarse crushing operation.
The basic
concept of the mineral Sizer( for sale in Brazil) , is the use of two rotors with large teeth, on
small diameter shafts, driven at a low speed by a direct high torque drive
system. This design produces three major principles which all interact when
breaking materials using Sizer Technology. The unique principles are; The
Three-Stage Breaking Action, The Rotating Screen Effect, and The Deep Scroll
Tooth Pattern.
For the most part advances in crusher(crusher for sale in
Pakistan) design have moved slowly. Jaw crushers have remained virtually
unchanged for sixty years. More reliability and higher production have been
added to basic cone crusher designs that have also remained largely unchanged.
Increases in rotating speed have provided the largest variation. For instance, a
48 inch (120 cm) cone crusher manufactured in 1960 may be able to produce 170
tons/h of crushed rock, whereas the same size crusher manufactured today may
produce 300 tons/h. These production improvements come from speed increases and
better crushing chamber designs.
