[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] The utility model realizes alloy classification and discharging by setting a double-layer automatic divider and a sunken material pit, which reduces the belt equipment facilities at the back end of the original system. The material drop point occupies a small area and is isolated by a retaining wall. The finished alloy material is classified in particle size and is not easily mixed. The material is discharged quickly and conveniently by using a loader.
[0011] The utility model solves the problem of large space occupation of the original crushing system and reduces two discharging belts after alloy screening;

[0014] This utility model crushes silicon, manganese, and chromium alloy blocks into finished products. After passing through a crusher and a discharge belt (SL1), the alloy is directly passed through a double-layered distribution device to meet the customer's three-level finished product requirements. Large blocks larger than 100 mm are classified as first-level finished products, alloy blocks 10-100 mm (adjusting the upper screen to control the upper particle size limit and the lower screen to control the lower particle size limit) are classified as second-level finished products, and alloy powders 0-10 mm are classified. The automatic distributor reduces the number of discharge belts (SL2 and SL3) and screens after alloy screening. A double-layer distributor is installed at the end of the discharge belt (SL1), directly separating the finished product from the powder. The finished product is then stored in a second-level storage silo on the ground. The automatic distributor is simple, practical, convenient, and has a low failure rate. It is safe and reliable.
