Grinding head for floor grinding machine comprising at least one belt pulley, floor grinding machines and methods

The present disclosure provides a method of operating a separator () for separating particles from a particle-laden airflow. The method comprises receiving, in the controller (), a separation unit status signal from the separation unit status sensor (), deriving, in the controller (), separator status data based on the separation unit status signal, communicating, via the communication device (), the separator status data to the external unit (), receiving, via the communication device (), incoming control data from the external unit (), determining, in the controller (), based on the separator status data and based on the incoming control data, whether to initiate separating unit maintenance, and selectively initiating separating unit maintenance based on said determination. The disclosure also provides a separator for implementing the method and a system comprising two or more such separators.

Separator, separator system and methods of their operation

This document provides a method of operating a floor grinding machine. The method comprises providing a grinding machinecomprising a frame, a motorand at least one grinding element, causing the motor to drive the grinding element so as to rotate at a rotational speed, while in contact with a floor surface to grind, polish or mill the floor surface, determining an actual value of a motor operating parameter, determining a nominal value of the motor operating parameter, comparing the actual value of the motor operating parameter with the nominal value of the motor operating parameter, if a difference between the actual value of the motor operating parameter and the nominal value of the motor operating parameter exceeds a predetermined difference threshold, determining at least one grinding parameter to be adjusted, and causing the at least one grinding parameter to be adjusted.

Floor grinding machine and method of operating floor grinding machine

The present document discloses a method of operating a separator () for separating particles from a particle-laden airflow, wherein the separator comprises a flow path (F), a separation unit (), arranged in the flow path (F), an impeller (), arranged in the flow path (F), and an electric motor (), configured to drive the impeller () so as to generate the airflow in the flow path (F). The method comprises initiating a power supply to the electric motor (), measuring a pressure in the flow path using a pressure sensor (), determining a direction of the airflow based on the pressure, and if the direction of the airflow does not correspond to a desired direction of the airflow, then changing a phase sequence of the power supply to the electric motor (). The document further discloses a separator () and a system comprising a separator () and a floor grinding machine ().
