Problems solved by technology

[0003] However, this known prior art has the disadvantage that on the one hand it does not meet the currently required production volumes of bulk materials, which are classified in the device
Furthermore, the device is complex to operate, since the device must be in vibrating motion and the air must also be conveyed through the two vibrating tables
This makes the device more complex in terms of construction, so that the plant is not cost-effective in terms of processing and operation

Embodiment Construction

[0077] exist figure 1 The device 1 for classifying bulk material is shown in perspective view in . The device 1 has a housing 10 which is suspended on a frame 9 by means of rods 25 .

[0078] The housing 10 has a door 8 which can be opened to provide access to the housing interior, in which a sieve or a sieve pack (not shown here) for classifying the bulk material can be accommodated. The housing 10 has two inlets 13 through which the bulk material can be conveyed into the housing 10 and then classified in the housing 10 by means of a sieve or sieve stack not shown. Mounted on the housing 10 is the drive mechanism formed by the electric motor 6 and the coupling mechanism formed by the coupling shaft 21 .

[0079] During operation, the device 1 is set in an oscillating motion by the drive of the electric motor 6 via the coupling shaft 21 . This is achieved by driving vibrating masses (not shown here), which are located in the top or bottom of the housing 10 and are connected...

Abstract

A method for classifying bulk material comprises the steps of conveying bulk material to at least one sieve of a device (1) comprising at least one housing (10) having a room. The housing (10) has at least one inlet (13) for conveying bulk material and at least one outlet (14) for discharging at least one fraction of the bulk material. The housing (10) has a top cover (15) and a bottom (16), wherein at least each vibration mass (17) is arranged on the top cover and the bottom. The device (1) has at least one mechanical coupling mechanism, wherein the vibrating masses are coupled and driven to each other by means of a mechanical coupling mechanism (21) arranged outside the inner chamber. The device (1) has a drive for driving a mechanical coupling. The method also includes the step of setting the housing (10) in vibratory motion by means of a driven vibrating mass. In a further method step, the bulk material is classified by means of a sieve. At least one fraction of the bulk material is then discharged from the housing through the outlet.

Description

technical field [0001] The invention relates to a method and a device for classifying bulk materials, the use of a classifying device and a method of retrofitting and / or equipping a classifying device as described in the preambles of the independent claims. Background technique [0002] From EP 0 182 831 B1 a device is known for sorting heavy objects, in particular stones or the like, from grain and other bulk materials. This device has two vibrating tables located one above the other at an angle, which are circulated by the same air. The upper vibrating table has a product inlet and a discharge point aligned with the middle part of the lower vibrating table, wherein the lower vibrating table is designed as a stone selection platform, that is, a sieve. Both vibrating tables have a common drive. The upper vibrating table is designed as a layering table, which has only at its lower end a place for the grain layers to fall. [0003] However, this known prior art has the disa...
