Abstract

A grinder for a coffee machine includes a first grinding disc disposed in a housing. A drive moves the first grinding disc about a rotational axis. A second grinding disc is disposed in the housing. There is a threaded part in which the second grinding disc is attached. The threaded part is screwable into the housing. A drive wheel is disposed coaxially with respect to the threaded part and rotates the threaded part with respect to the housing. A grinding gap between the two grinding discs is thereby able to be set. A setting wheel co-operates with the drive wheel, the setting wheel being attached to the housing. A supply opening is disposed in the housing for supply of coffee beans to be ground. A path guide opening guides away the coffee ground between the two grinding discs. A holder is adjustably attached to the housing and is fixable in any position. The setting wheel which is attached to the holder can engage the drive wheel in any desired position with respect to the housing, whereby the grinder can be inserted into different types of coffee machines.
