Complete equipment for perlite sand making production line

Abstract

The invention belongs to the field of non-metal ore sand making. Complete equipment for perlite sand making production line comprises a raw material bin, a first crusher, a rotary dryer, a second crusher, a crushing mill, a screening assembly, a finished product bin and a material returning assembly, wherein the raw material bin is correspondingly connected with the first crusher; a first conveying unit is arranged between the first crusher and the rotary dryer; a second conveying unit is arranged between the rotary dryer and the second crusher; a third conveying unit is arranged between the second crusher and the crushing mill; a fourth conveying unit is arranged between the crushing mill and the screening assembly; and the finished product bin is connected with a finished product discharging port of the screening assembly. The complete equipment has the advantages of being good in product grain shape, adjustable in product grain size and compact in structure of the production line, and being capable of guaranteeing that all procedures of the whole production line are implemented orderly, improving the working efficiency of all the procedures, and optimizing the energy efficiencystructure of the production line.

Description

technical field [0001] The invention belongs to the field of non-metallic ore sand making, and in particular relates to a complete set of equipment for a perlite sand making production line. Background technique [0002] Perlite is brittle, light in weight, and can expand rapidly under heating conditions. It has the characteristics of sound insulation, heat insulation, high temperature resistance, strong adsorption, small capacity, stable chemical properties, and acid and alkali resistance, so it is widely used. At present, my country's expanded perlite is the most widely used light-weight insulation material in China. According to the statistics of relevant departments, the current application proportion of expanded perlite in the market in my country is: about 60% for construction projects, about 30% for heat pipe insulation, and about 10% for decorative materials. [0003] The current perlite sand making process in my country mainly includes: raw ore—coarse crushing (jaw...

AI Technical Summary

Problems solved by technology

The outstanding problems of perlite sand making are: (1) The performance of perlite sand making equipment is uneven, the energy consumption is high, and there is a lack of special perlite sand making equipment; The particle size distribution cannot be adjusted; (3) The efficiency of the screening equipment is low, and the reliability of the equipment is poor; (4) The product has poor particle shape, low strength, and is easy to crush after expansion
