Do you know the three discharge adjustment devices of the cone crusher?Date: 2019-10-25 Views:
Cone crusher is the mainstream equipment of mine crushing industry at present.In the mine production, the cone crusher is generally used for medium and fine crushing various materials.As we know, the discharge size of the cone crusher is determined by the distance between the broken wall and the rolling mortar wall.But many people don't know much about devices that adjust the distance between the two.Do you know the three discharge adjustment devices of the cone crusher?
1. Adjusting device of fixed pulley
Fixed pulley adjustment device refers to the use of rope through fixed pulley, around the rack, the end hanging on the hook, the other end with external lifting equipment pull, make the adjustment sleeve rotation, thus changing the distance between the broken wall and rolling mortar wall.In the cone crusher of the broken wall and rolling mortar wall wear serious, need to replace when also want to use this method, let the upper part of the body all wrung out, then replace two lining plate.When adjusting the cone crusher, the compression spring is to increase the discharge size of the discharge mouth, elongate the spring is to reduce the discharge size of the discharge mouth, the role of the adjustment sleeve is to stretch or compress the spring.
2. Hydraulic push hand adjustment device
The adjustment principle of the hydraulic push hand adjustment device and the fixed pulley adjustment device is the same, which is to promote the spring stretching or compression by pushing the rotation of the adjustment sleeve, so as to adjust the size of the discharge material from the discharge port of the cone crusher.But the way of adjusting the hydraulic push hand is not to use the fixed pulley, also do not need rope, only need to use two hydraulic push hand to launch the thrust, this thrust can push the adjustment sleeve rotation, so as to adjust the size of the discharge port of the cone crusher.Spring cone crusher of two kinds of discharging mouth adjusting device has certain convenience, relatively with hydraulic driving force to adjust the discharging mouth size than with crown block to adjust more convenient, but in the spring cone crusher wear parts for the replacement, namely crushing wall and rolling mortar wall with roller skating device to replace more save time, because the hydraulic driver is slow, so the user can according to their own needs, the freedom of choice.
3. Hydraulic motor adjustment device
The adjusting device of hydraulic motor consists of three parts: hydraulic power department, size gear and adjusting department.The hydraulic power station in the hydraulic power department provides the oil pressure and flow rate used by the hydraulic motor to the cone crusher, and the hydraulic motor provides power for the gears.The hydraulic system provides power to the adjusting device of the hydraulic regulating motor and the locking device. When the crushing works, the locking system locks the whole adjusting system, and the hydraulic motor does not work.When adjusting work, the locking system is released and the hydraulic motor works.Adjustment and locking are controlled by the same hydraulic station.
Hydraulic motor adjustment device has the following five advantages:
(1) during the whole adjustment process, there is no need for special personnel to operate on site;
(2) it can run continuously and run several times fast;
(3) high degree of automation;
(4) remote centralized control can be realized;
(5) reduce labor intensity and improve labor efficiency.
In the convenience of adjusting the spacing between the broken wall and the rolling mortar wall, the hydraulic motor > hydraulic push hand > fixed pulley.In addition, spring cone crusher generally choose to use hydraulic push hand or fixed pulley adjustment device, multi-cylinder hydraulic cone crusher generally choose to use hydraulic motor adjustment device.
