Feeding device, can effectively improve the utilization of equipment, ensure the stability of the milling process. Root feeding amount of adjustment can be changed by moving the shutter gap 5r feed grinder, or to change feed roller speed execution. Mechanical feed material level automation systems are gravity-sensing regulator. Gravity Raymond 3r level sensors can observe the barrel material according to the profit and loss position, adjust the feed or feed roller shutter speed to control the volume of feed through the lever and pneumatic actuators. Whether feeding valves or other forms of fan-shaped, is by changing the cross-section of the feed gap control the volume of feed, the downside is that a large amount of adjustment of the gradient. Raymond machine works: Raymond machine starts working when the machine casing material from the side of the hopper to join the machine to smash, to rely on the host plum hanging shelves mill rolls around the vertical axis of revolution, but it has also conducted Raymond rotation, rotation of the centrifugal force generated when Raymond 6r, swing under the action of centrifugal grinding rolls outward, pressed on the grinding ring, then the blade will automatically scoop up material will Materials sent between roller and grinding ring, rolling in the rolling mill rolls so that the materials are crushed.
