Quartz sand circulating crusher

Abstract

The invention provides a quartz sand circulating crusher which comprises a jaw crusher and a circulating frame, wherein the jaw crusher comprises a feeding port and a discharging port; a collecting device is arranged below the discharging port; one end of the collecting device is arranged below the discharging port, the other end is arranged at a position above the circulating frame and near the jaw crusher; the quartz sand circulating crusher further comprises a conveying pipeline; a bottom end of the conveying pipeline is inserted at one end of the bottom end of the circulating frame remotefrom the collecting device; a top end of the conveying pipeline is fixed at an upper end of the feeding port; a lifting opening is opened in a lower end of the conveying pipeline; the lifting openingfaces the bottom of the circulating frame; a spiral rod is fixedly mounted in the conveying pipeline; the bottom end of the spiral rod penetrates the circulating frame and extends to the outside of the circulating frame; the bottom end of the spiral rod is fixedly connected with a rotating motor; the rotating motor drives the spiral rod to rotate in a spiral direction. The conveying pipeline and the spiral rod are utilized to realize linkage of quartz sand crushing and transportation, thereby improving the production efficiency.

Description

technical field [0001] The invention relates to a crusher, in particular to a quartz sand circulation crusher. Background technique [0002] In the prior art, the crusher usually puts the material evenly into the crusher cavity, and the material is torn by impact and shearing to tear the material. After the crushing is completed, the crushing degree of the crusher is adjusted according to the crushing situation, and the material is put into Crushing until the material is broken to the required degree, in the whole process, the material needs to be transported many times, which prolongs the production time of the material and reduces the production efficiency. In the prior art, there is one jaw crushing followed by two or three other crushings. For example, in the process disclosed in patent CN103418479A, after the first crushing of calcite, the second crushing and screening are carried out, and the unqualified calcite is returned. To the crusher for re-crushing, the crushin...
