Embodiment 1

[0016] Embodiment one: if figure 1 As shown, the Raymond machine grinding device includes a grinding ring 1 and at least two grinding rollers 2 uniformly distributed circumferentially along the axis of the grinding ring 1. The grinding rollers 2 are in the shape of a drum with a large middle and small ends. The internal cavity of 1 is a common cylindrical shape. This structure makes the grinding roller have a certain amount of pre-wear, thus improving the service life of the grinding roller.

Embodiment 2

[0017] Embodiment two: if figure 2 As shown, this embodiment is basically the same as Embodiment 1, the difference is that the drum-shaped grinding roller 2 is a split structure, including a middle roller body 21, and a drum-shaped outer surface sleeved on the middle roller body 21 The grinding sleeve 22 is provided with a fastening device 23 between the intermediate roller body 21 and the grinding sleeve 22; the fastening device 23 can adopt a conventional fastening method, such as bolt connection; the intermediate roller body 21 and the grinding sleeve 22 The cross section of the joint part can be circular or square.

Embodiment 3

[0018] Embodiment three: as image 3 As shown, the Raymond machine grinding device includes a grinding ring 1 and at least two grinding rollers 2 uniformly distributed circumferentially along the axis of the grinding ring 1, and the grinding rollers 2 are drum-shaped with a large middle and small ends; the grinding ring The inner cavity of 1 is the drum-shaped cavity corresponding to the drum-shaped grinding roller 2. In addition to the advantages of the first embodiment, this structure increases the contact area between the material, the grinding roller and the grinding ring, and improves the grinding opportunity. During the use of ordinary Raymond mills, the grinding roller 2 wears first, and then the grinding ring wears into a drum-shaped cavity. In this case, the use of the grinding roller of the present invention can prolong the service life of the grinding ring and reduce production costs , this structure is also within the protection scope of the present invention.

Abstract

The invention discloses a Raymond grinding device, which is characterized by the following: displaying drum shape of large middle and two small ends; increasing the rotary radius of grinding roll; improving the linear speed of grinding roll surface; increasing the weight and impact force of grinding roll; improving the grinding fineness and efficiency; lengthening the usage lifetime.

Description

technical field [0001] The invention relates to a Raymond machine, in particular to a grinding roller and a grinding ring of the Raymond machine. Background technique [0002] Raymond machine is also called suspension roller mill. Its grinding principle is as follows: when the machine is running, the grinding roller generates a centrifugal force and presses against the grinding ring to form a grinding force. Use this force and the grinding roller to move along the circle of the grinding ring and its own rotation to grind the material to the required particle size. as attached Figure 5 The grinding roller 2 of the Raymond machine shown is cylindrical. During the working process, the grinding roller and the grinding ring 1 are used together to grind the hard ore by extrusion and friction, and its outer surface wears quickly. After a period of use, its appearance is as attached Figure 6 As shown, the middle part of the roller surface is concave, resulting in smaller grindin...
