Example Embodiment

[0031] In order to make it easy to understand the technical means, the new features, the purpose and the effect achieved by the present invention, the present invention will be further explained below in conjunction with specific drawings.

[0032] A method for sorting and magnetic separation according to the particle size of quartz sand includes the following steps: first crushing the quartz stone; then using a screen to classify the quartz sand. The size of the primary screen is 60 mesh, and the size of the secondary screen is 60 mesh. The size is 180 mesh; then the three types of quartz sand with different particle sizes after grading and screening are input into three sets of magnetic separators for magnetic separation. The three sets of magnetic separators are all magnetic separators with two magnetic cylinders. The surface magnetic field intensity of the two magnetic cylinders corresponding to the quartz sand on the upper part of the screen after screening is 0.53T and 0.89T...

Abstract

The invention discloses a method for carrying out classification magnetic separation according to the particle sizes of quartz sand, and a magnetic separator thereof, and relates to the technical field of quartz sand treatment. The method is characterized by comprising the following steps: crushing quartz stone at first; then carrying out grading screening by virtue of sieve screens, wherein the size of the first-stage sieve screen is 50-70 meshes, and the size of the second-stage sieve screen is 170-190 meshes; and then inputting the quartz sand subjected to the grading screening into the magnetic separator separately and carrying out magnetic separation. The magnetic separator comprises a screening device and a magnetic separator body, wherein the screening device is arranged at the upper side of the magnetic separator; a charge port is formed in the upper part of the screening device; the screening device comprises the first-stage sieve screen and the second-stage sieve screen; the second-stage sieve screen is arranged at the lower side of the first-stage sieve screen; charge channels connected to the magnetic separator body are formed in the screening layers of the first-stage sieve screen and the second-stage sieve screen; and the magnetic separator body comprises a rack, a first magnetic drum, a second magnetic drum and a transmission motor. The iron removal efficiency of the magnetic separation method and the magnetic separator is greatly increased.

Description

[0001] Technical field: [0002] The invention relates to the technical field of quartz sand treatment, in particular to a method for classifying magnetic separation according to the size of the quartz sand grain size and a magnetic separator thereof. [0003] Background technique: [0004] At present, there are many types of magnetic separators at home and abroad. The cost of a single large-scale magnetic separator is too high for local small and medium-sized enterprises to bear, and the iron removal effect of small magnetic separators is difficult to meet the requirements. In this context, it is necessary to develop a new type of magnetic separation equipment that can effectively reduce the content of iron impurities in quartz sand. [0005] The study found that the iron content in quartz sand with different particle sizes varies greatly, such as figure 2 (a), wherein, the iron content in the 30-50 mesh and 180-300 mesh quartz sand is significantly higher than that in the 60...
