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 feed gap, or change feed roller speed execution. Mechanical feed material level automation systems are gravity-sensing regulator. Gravity Level sensor according to the profit and loss observed barrel material level, regulating feeding or feed roller shutter speed through the lever and pneumatic actuator to control the volume of feed. 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. Stress and Raymond mill grinding wear parts easy to make martensite extrusion load cracks, when the eutectic carbides along the grain boundaries into a network 4r Raymond, will promote its brittle crack propagation Raymond 6r, the presence of residual austenite at this time to prevent the extension of a good crack, to the number on Raymond often need to replace the grinding rolls. Raymond roller mill wear parts are easy to wear, so it's useful life and its environment are closely related, so Raymond roller mill machine to suit different needs, requirements for surface condition of the roller are also different. Some of the work roll surface grinding 5r Raymond, Roll Roll, Roll roll shape is cylindrical; some rolls and grinding teeth, only a rough roller surface, roll called a smooth roll, light ends of the rolls slightly taper. Raymond Raymond 6r_ Baotou _ Yuxin Senda provided by Henan new Senda Heavy Machinery Co., Ltd.. Henan new Senda Heavy Machinery Co., Ltd.
