High-temperature calcined sand raw material pretreatment method and matched integrated equipment

Abstract

The invention relates to the technical field of calcined sand, and particularly discloses a high-temperature calcined sand raw material pretreatment method and matched integrated equipment, the high-temperature calcined sand raw material pretreatment method comprises a tank body, a mounting disc is rotatably mounted on the inner wall of the tank body, a plurality of treatment mechanisms are arranged on the mounting disc, and a scattering mechanism matched with the treatment mechanisms is arranged at the bottom of the mounting disc. According to the matched integrated equipment, the fixing ring and the heating rod rotate along with the mounting disc, large hardened particles and large particles in raw materials can collide with crushing convex points on the outer wall of the heating rod at a certain frequency under the centrifugal force action of the fixing ring, and therefore it is guaranteed that the mesh number of the raw materials is within the qualified range; and generated raw material powder is removed from the raw materials under the suction effect of the dust collector, it is guaranteed that the mesh number of the raw materials is within the qualified range, meanwhile, the raw materials in the fixing rings can be heated to a certain degree through the heating rods, and the dryness of the raw materials is guaranteed.

Description

technical field [0001] The invention relates to the technical field of calcined sand, in particular to a raw material pretreatment method of high-temperature calcined sand and supporting integrated equipment. Background technique [0002] Calcined sand can be divided into the following categories: [0003] Natural sand: It is a rock particle with a particle size less than 4.75mm formed by natural weathering, water erosion, and accumulation. It is divided into river sand, sea sand, and mountain sand according to the living environment. The surface of river sand particles is smooth, relatively clean, good in texture, and widely produced. [0004] Artificial sand: It is a fine aggregate obtained by manual processing that meets the specifications. It usually refers to the clean fine aggregate obtained by removing most of the soil and fine powder by vacuum suction or other methods during rock processing, or by washing stone chips with water. material. Broadly classified, machi...

Problems solved by technology

[0006] However, in the pretreatment process of the existing corundum raw materials, various raw materials need to be stirred and mixed first, and various raw materials will produce a large amount of raw material powder after a certain frequency of collision and friction in the process of stirring and mixing. Strict requirements, the raw material powder produced will have an irreversible impact on the quality of the later corundum. Therefore, in order to solve such problems, we propose a high-temperature calcined sand raw material pretreatment method and supporting integrated equipment
