Breaking efficiency and high-speed rotation of the water drop type feed hammer mill
- Jan 03, 2019 -

When the rotor of the water drop type feed hammer mill rotates at a high speed, the hammer becomes radial (for the rotor of the suspended hammer) due to the centrifugal force. The rubber material enters the machine after being rolled by the feeding roller, and is immediately broken into particles by the impulse and tearing action of the hammer. The granule glue is discharged from the sieve hole in the bottom of the machine. Block, leaving the hammer to impact again until it passes through the mesh. The hammer mill does not rely on the full energy of the rotor components to break the rubber, but mainly relies on the work of the kinetic energy of the hammer to complete the crushing of the rubber.

The drip-type feed hammer mill has the same kinetic energy of the hammer when the number of hammers is constant. The more the hammer will be hammered per unit time, the higher the crushing efficiency. The finer the particles, but the higher the rotational speed, the higher the load on the motor, the vibration and noise of the machine, and the higher the strength of the machine parts and the balance of the rotor.

In the case of the water drop type feed hammer mill with the same total area of the discharge screen, the opening ratio is related to the aperture size of the opening, the number of holes, the hole spacing and the arrangement of the holes. As the opening rate of the discharge screen increases, the discharge capacity of the screen increases. It should be pointed out that the opening rate of the discharge screen must ensure that the discharge amount is greater than (minimum should be equal to) the feed amount, otherwise the machine will be clogged, and once blocked, the rubber particles that are not discharged from the machine will roll into a large rubber ball, the motor will be overloaded and burned.
