Latest Patents

Vahteri holds a patent for a "Method for regulation of grinding process in a pocket grinder." This method involves pressing a wood batch in at least one pocket against a rotating grindstone. The grinding plate is movable within the pocket, allowing for the calculation of the apparent pulp quantity produced at measuring points at fixed intervals of the grinding stroke. The method also accounts for changes in wood batch density during the grinding stroke. By comparing the calculated value with a target value for the pulp quantity, the grinding process can be regulated to achieve optimal results. Additionally, the calculated value is corrected based on the hydraulic pressure used during the grinding stroke, ensuring a consistent pulp quantity.
