The grinding pump is customarily called a fine homogenizer in the viscose industry. The main grinding machine is a double grinding disc structure with a combination of rotor (moving tooth disc) and stator (stationary tooth disc). Each rotor and stator has 3 layers. It is composed of independent tooth discs. The multi-layer tooth discs are combined from wide gap to narrow gap and coarse to fine, from inside outside. Enable the original granule materials with different size to enter the pump cavity smoothly for layer-by-layer grinding and dispersion, fine and homogeneous. The gap between the rotor and the stator can be adjusted according to the particle size of raw medium or the technological requirements. It is divided into three series: fixed grinding pump, manual grinding pump and automatic grinding pump.
