Processing system for kiln tail ceramsite caking materials

Abstract

The invention discloses a processing system for kiln tail ceramsite caking materials. The processing system comprises a feeding device, a material lifting device, a spiral extrusion feeder, a cage-type crusher, a first-level particle separating subsystem, a second-level crushing and separating subsystem and a dust removing subsystem which are connected in sequence. The first-level particle separating subsystem comprises three sets of separating equipment. The first swinging screen equipment is of a double-layer screen cloth structure. Second swinging screen equipment is of a double-layer screen cloth structure. The dust removing subsystem is simultaneously connected with the first-level particle separating subsystem, an impact-type crusher, the second separating equipment and third separating equipment through a pipeline. According to the processing system for the kiln tail ceramsite caking materials, the method of combining the spiral extrusion feeder with the cage-type crusher is adopted, and the proportion of bonding aggregates in the screened materials is decreased; meanwhile, pre-shaping processing is conducted on all particles, and thus the surface states of the particles are improved.

Description

technical field [0001] The invention relates to a system for crushing, separating, screening and reusing cohesive particles, and belongs to the technical field of ceramsite generating systems. Background technique [0002] With the popularization and application of oil, oil and natural gas hydraulic fracturing technology, artificial ceramsite fracturing proppants have begun to replace natural quartz sand and are widely used in the construction of low-permeability oil and gas wells. Artificial ceramsite fracturing proppant is a ceramic spherical particle with a certain strength. Its production process mainly includes process steps such as powder making, semi-finished product granulation, finished product calcination, and finished product screening. The distribution range of conventional ceramsite proppant particles is Between 0.1-1.2mm. [0003] For the sieving process of ceramic particles after sintering, it often happens that the size of a single ceramic particle is smalle...

Problems solved by technology

[0004] It is worth noting that as the size of ceramic particles decreases, the proportion of particles bonded and agglomerated during the sintering process increases, and the proportion of particles with fine powder adhered to the surface increases, which further increases the difficulty of sieving particles after sintering. Reduce the rate of qualified products, restricting the large-scale production process of products
