Description

Technical Field

[0001] The utility model relates to the field of lime treatment equipment, in particular to a quicklime crushing system. Background Art

[0002] Hammer crushers are commonly used in the field of quicklime crushing, and such hammer crushers are all equipped with a sieve plate at the bottom. This sieve plate structure can ensure the discharge particle size. However, when a double-stage crusher processes quicklime blocks, the particle sizes of the quicklime blocks are relatively large during primary crushing. When the sieve holes of the primary sieve plate are relatively small, the quicklime blocks are easily blocked at the primary sieve plate after primary crushing, and the quicklime fragments accumulate at the primary sieve plate, increasing the wear of the hammers. Therefore, it is necessary to improve the structure of the primary sieve plate to reduce the accumulation. During secondary crushing, a high manganese alloy steel is often used for the secondary sieve plate, but problems such as cracks and chipping are likely to occur during the use of the high manganese alloy steel. After the quicklime is crushed, quicklime particles with a particle size of 5-15 mm are formed, and the quicklime particles can be made into slaked lime after digestion. The quicklime particles formed after crushing often need to be stored in a temporary storage bin and then sent to a digestion device for digestion. When the existing quicklime particle bin is discharged for use after temporary storage and accumulation, sometimes the discharging is not convenient, and a rubber hammer needs to be used to vigorously knock on the bin to facilitate the discharge, increasing the workload of manpower.
