たのが実情である。 In screens that sieve materials such as ore, coal, coke, lime, etc. by particle size, relative movement is performed between the materials and the screen for a predetermined period of time, separating those that pass through the holes in the screen and those that do not. I try to separate them. By the way, when the material to be sorted moves relatively on the screen or passes through the holes in the screen, the screen is worn out due to the rubbing and scratching of the material to be sorted against the screen. It varies depending on the shape, bulk density, and fluidity of the object. Then,
Conventional screens include woven wire mesh, punched wire mesh,
Rubber screens, urethane screens, etc. have been used, but the reality is that conventional screens are susceptible to wear due to rubbing and scratching of the material to be sorted, resulting in a short lifespan.

変形によつて緩和吸収できる。 Next, the effect will be explained. When screening material such as ore, coal, coke, lime, etc. is to be sieved by particle size using the screen 1, the material to be selected is placed on the screen 1 and the screen 1 is vibrated by a vibrating device. Then, among the materials to be sorted on the screen 1, those smaller than the size of the holes 3 will fall through the holes 3, and those larger than the size of the holes 3 will remain on the screen 1 and be sorted. You can sift through things. In this case, the upper surface side of the screen 1 and the upper inner wall portion of the opening 3, which are easily worn out by rubbing or scratching by the sorted material during the sieving operation, are constituted by the first and second pieces 5 and 6 made of ceramic. As a result, the abrasion of the screen 1 is slow and the screen 1 can have a long service life, and since the material to be sorted does not easily adhere to the ceramic, the screen 1 is less likely to be clogged. Like the first one.
Since it is composed of the second pieces 5 and 6 and the base 4 made of rubber, large noises such as metallic sounds are not generated when the material to be sorted comes into contact with the screen 1.
A good work environment can be created. Furthermore, as mentioned above, since the base 4 of the screen 1 is made of rubber, the elastic deformation of the base 4 can cushion and absorb shocks caused by collisions between the material to be sorted and the screen 1 during sieving work. .

を有し、実益大である。 As described in detail above, according to the present invention, pieces made of ceramic are laid over almost the entire top surface of the base, so the screen is less likely to wear out, making it possible to extend the life of the screen. Since it does not adhere easily, the screen is less likely to become clogged. In addition, since the base is also made of rubber, there is no large metallic sound when the material to be sorted comes into contact with the screen, creating a good working environment. The elastic deformation of the base can buffer and absorb shocks caused by collisions with other objects. The present invention has the above advantages and is of great practical benefit.
