Abstract

Vibrating equipment is provided with a vibrating body supported on a frame. The vibrating body is vibrated by at least one first vibrating device, wherein a vibrating deck of the vibrating body moves in a vertical direction and in a machine direction. The vibrating equipment additionally includes at least one second vibrating device arranged to vibrate the vibrating deck in a lateral direction. Further, a method of processing a material is disclosed.

First claim

The invention claimed is:

1. Vibrating equipment for processing a material, comprising:
a frame;
at least one vibrating body supported on the frame vertically by spring elements;
at least one vibrating deck arranged in the vibrating body, the at least one vibrating deck having a feed end and a discharge end, wherein a machine direction of the vibrating equipment, which is determined by a direction of the feed end and the discharge end, corresponds to a direction of motion of the material to be processed;
at least one first vibrating device for vibrating the vibrating body and causing the vibrating deck to move in a vertical direction and in the machine direction; and
at least one independent second vibrating device causing the vibrating body to vibrate in a lateral direction relative to an xy-plane,
wherein the at least one first and second vibrating devices are configured to vibrate the deck in the machine, vertical and lateral directions simultaneously.

2. The vibrating equipment as claimed in claim 1 , wherein the at least one second vibrating device is physically and functionally independent of the at least one first vibrating device.

3. The vibrating equipment as claimed in claim 1 , wherein the vibrating body includes side plates, which are in the machine direction and delimit the vibrating body in the lateral direction, the at least one second vibrating device being mounted to a side plate of the at least one vibrating body, whereby the at least one second vibrating device vibrates the at least one vibrating body and the vibrating deck in the lateral direction.

4. The vibrating equipment as claimed in claim 1 , wherein the at least one second vibrating device is arranged at a center of gravity of the vibrating equipment.

5. The vibrating equipment as claimed in claim 1 , further comprising two second vibrating devices, the second vibrating devices being arranged at a center of gravity and on opposite sides of the at least one vibrating body.

6. The vibrating equipment as claimed in claim 1 , further comprising at least two second vibrating devices arranged at a distance from each other and at an equal distance from the center of gravity.

7. The vibrating equipment as claimed in claim 1 , further comprising two second vibrating devices arranged at a center of gravity, each second vibrating device including a rotating device and at least one unbalance weight, which is rotated by the rotating device.

8. The vibrating equipment as claimed in claim 7 , wherein a pair of second vibrating devices is arranged at least on one side of the at least one vibrating body, the pair of second vibrating devices being arranged at the center of gravity.

9. The vibrating equipment as claimed in claim 7 , wherein rotation directions of the two second vibrating devices are transverse to each other.

10. The vibrating equipment as claimed in claim 1 , wherein at least two second vibrating devices are arranged in the at least one vibrating body at a different vertical height from a center of gravity, whereby a torque around a machine direction axis is generated in the at least one vibrating body; and a reciprocating turning motion relative to the machine direction axis is generated in the vibrating deck during operation.

11. The vibrating equipment as claimed in claim 10 , wherein a position of the at least two second vibrating devices is adjustable.

12. The vibrating equipment as claimed in claim 1 , wherein the vibrating equipment is a vibrating screen provided with at least one vibrating screen deck, the vibrating screen deck including several screening apertures.

13. The vibrating equipment as claimed in claim 12 , further comprising at least two vibrating decks arranged one above the other and provided with a mutually different aperture size.

14. The vibrating equipment as claimed in claim 1 , wherein the vibrating equipment is a vibrating feeder provided with a blind vibrating deck.

15. A method of processing a material, the method comprising the steps of:
using vibrating equipment including a frame, a vibrating body positioned above the frame, spring means between the frame and the body, and at least one vibrating deck having a feed end and a discharge end;
feeding the material on the at least one vibrating deck at the feed end;
vibrating the vibrating body using at least one first vibrating device and allowing the at least one vibrating deck to move in a vertical direction and in a machine direction of the vibrating equipment;
moving the material on the at least one vibrating deck towards the discharge end in the machine direction;
discharging the material at the discharge end;
vibrating the vibrating body using at least one second vibrating device, wherein the vibrating body vibrates in a lateral movement relative to an xy-plane; and
generating the lateral movement independently of the vertical movement and the machine direction movement,
wherein the at least one first and second vibrating devices are configured to vibrate the deck in the machine, vertical and lateral directions simultaneously.
