Background
The chrome corundum is prepared by taking alumina powder obtained by crushing alumina blocks as a main raw material, adapting to chrome oxide and the like, and smelting at a high temperature, and has higher toughness than white corundum. Alumina is a compound with high hardness, and after coarse crushing by a jaw crusher, fine crushing by a roller crusher is needed to meet the granularity requirement of the follow-up process on stones. The materials which are finely crushed by the double-roller crusher are screened out by a screening machine, the materials with different particle diameters enter the next procedure according with the requirements, and the materials which do not meet the requirements return to the last-stage crushing device to continue crushing.
Because the crushing amount of the crushing device is large, the sorting flow of the screening device cannot meet the requirement, and the intermittent shutdown of the crushing device is caused, so that the production efficiency is influenced.

Two screening machines are arranged in one feed box to increase screening flow. The blanking receiving plate is covered on the screen mesh to prevent falling materials from causing impact damage to the screen mesh, and the blanking receiving plate can relatively move with the screening machines, namely, the two screening machines are not rigidly connected, and the vibration screening effect of the screening machines is not affected.
The blanking end of each sieving machine is provided with a transverse supporting rod, and the blanking receiving plates are positioned on the two supporting rods; the blanking receiving plate is provided with a limiting device which can prevent the blanking receiving plate from vibrating and falling.
Further, the limiting device is a limiting bolt which is arranged on the left baffle and the right baffle of the screening machine; two sides of the front end and the rear end of the blanking receiving plate are provided with vertical limit baffles.
Further, a gap is reserved between the limit baffle and the limit bolt, and the blanking receiving plate can slightly move between the front limit bolt and the rear limit bolt.
The feed box is arranged on a supporting frame, and the supporting frame spans the blanking ends of two screening machines.
The two ends of the feed box are provided with supporting lugs, and the supporting lugs are arranged on the supporting frame through fixing bolts.
Compared with the prior art, the utility model has the following beneficial effects:
