Embodiment 1

[0036] Such as Figure 4-Figure 10 As shown, the present invention is an electromagnetic vibrating screening device for a ceramic raw material roller mill, which includes a trough 11 arranged outside the grinding disc 2 of the roller mill, a base 12 and a vibration generator connected between the trough and the base. Device 13, in the trough 11 is provided with an inclined upward inclined material partition 11-6, the inclined material partition 11-6 divides the material trough into upper and lower layers 11-1, 11-2, and the upper and lower layers of the inclined material partition 11-6 There are several hole positions for installing screens. In this embodiment, there are several square holes for the raw material particles to fall on the inclined material plate 11-6, and a 10-mesh screen is installed on the inclined material plate 11-6. Net 11-7, the raw material particles passing through the screen 11-7 fall to the bottom plate of the lower chamber 11-2 of the trough, move to ...

Embodiment 2

[0045] The difference between this embodiment and Embodiment 1 is that the trough is an annular trough composed of 8 sections of chute components, and each section of the trough component is in the shape of a 1 / 8 ring, and is evenly distributed along the circumference of the outer edge of the grinding disc. distributed.

[0046] It is worth noting that the material trough can also be set as a welded one-piece circular ring-shaped trough.

[0047] Compared with the prior art, the present invention has the main distinguishing technical feature that the raw material particles after roller milling are directly in the roller mill, and the screening and coarse material return to the grinding table are completed, eliminating the need for screening equipment and belt conveyors , shorten the process, reduce equipment, improve production efficiency, reduce power consumption and material consumption in the screening process, and have significant progress.

[0048] When the material laye...

Abstract

The invention discloses an electro-magnetic vibrating and screening and returning device of a ceramic raw material roller mill. The material distributing and returning device is characterized in that the material distributing and returning device comprises a material groove formed in the outer edge of an abrasive disk of the roller mill, a base and a vibration generating device connected between the material groove and the base, the material groove is internally provided with an inclined material partition plate which is spirally upwards, the inclined material partition plate partitions the material groove into an upper layer and a lower layer, the inclined material partition plate is provided with a plurality of hole locations for mounting screens and / or holes bringing convenience to blanking, a lower-layer cavity is provided with a material outlet, and sieved raw material particles fall on a bottom board of the lower-layer cavity of the material groove; the upper layer of the material groove is provided with one or more discharging inclined grooves leading to a roller milling rail, and each discharging inclined groove is provided with one or more blanking openings. Electro-magnetic force is adopted, no rotating component works, lubricating is not needed, it is convenient to adjust the feeding quantity, and automated control is achieved easily.

Description

technical field [0001] The invention relates to the technical field of ceramic machinery, in particular to a screening and returning device for roller mill equipment used for processing ceramic raw materials. Background technique [0002] In the production process of ceramic products, the preparation of raw materials is a very important link. The traditional process is: such as figure 1 As shown, the coarse and hard sand and gravel are processed into coarse materials with a particle size of less than 15mm by a jaw crusher, and then sent to a ball mill for grinding through a feeder. The ball milling time is as long as 12-16 hours. Stone, ball lining and other materials consume a lot. In recent years, roller mills have been widely used in cement, coal, mining and other industries. Because of their high grinding efficiency, energy saving and consumption reduction, they have been used in the ceramic industry. The new process is: as figure 2 As shown, the coarse and hard sand...
