Abstract
A conveyor grate for conveying bulk material (preferably cement clinker) in a conveying direction, which has at least two conveying means and at least one motor for advancing such conveying means in the conveying direction and for retracting the conveying means, The grate can be installed and operated at reduced costs, if a first of these conveying means is coupled via a first clutch to the motor and a second of these conveying means is coupled via a second clutch to the same motor.
Claims13
A conveyor grate configured to convey bulk material in a conveying direction, the conveyor grate comprising:
- at least two conveying means, and
- at least one motor configured to advance the at least two conveying means at the same time in the conveying direction and to retract the at least two conveying means,
- wherein a first of the at least two conveying means is selectively coupled via a first clutch to the at least one motor and a second of the at least two conveying means is selectively coupled via a second clutch to the same at least one motor,
- wherein establishing of a respective selective coupling between the at least one motor and either the first or the second of the at least two conveying means includes closing a respective clutch of the first and second clutches, and releasing of said respective selective coupling includes opening the respective clutch.
A method for conveying material with a conveyor grate with at least a first conveying means and at least a second conveying means, the method comprising:
- advancing the first and the second conveying means simultaneously,
- retracting the first and the second conveying means asynchronously, and
- effectuating at least one of (a) operating a first clutch of the conveyor grate to thereby engage or disengage the first conveying means with at least one motor of the conveying grate, and (b) operating a second clutch of the conveyor grate to thereby engage or disengage the second conveying means with the at least one motor.
