Gangue raw material processing device for insulating brick production

Abstract

The invention discloses a gangue raw material processing device for insulating brick production. The device comprises a crushing shell, wherein a feed hopper is arranged in the middle of the upper end part of the crushing shell; a demagnetizing device is arranged in the feed hopper, and consists of two crossed magnetic rods; two first-grade crushing rollers and two second-grade crushing rollers are arranged in the crushing shell from top to bottom; the first-grade crushing rollers coat first-grade roller shafts; the second-grade crushing rollers coat second-grade roller shafts; and multiple crushing projections are uniformly arranged on the first-grade crushing rollers and the second-grade crushing rollers. The device has the following beneficial effects: firstly, raw materials are magnetically separated to screen out iron-contained impurities so as to prevent a crushing device from being damaged; and the first-grade crushing rollers and the second-grade crushing rollers are arranged for selectively crushing incoming materials according to the volume size, so that the crushing efficiency is improved, and the crushing pressure is relieved.

Description

technical field [0001] The invention relates to the technical field of heat preservation brick production, in particular to a coal gangue raw material processing device for heat preservation brick production. Background technique [0002] Insulation brick is a new type of building energy-saving insulation technology with inorganic composite materials as the main raw material. It is an ideal technology to replace traditional wall insulation. Insulation bricks integrate excellent thermal insulation effect into the wall while building the wall. It has low thermal conductivity, high strength, firmness and durability, simple construction, light weight and easy loading and unloading, economical, green and environmental protection, sound insulation and fire prevention.

Problems solved by technology

[0003] Coal gangue is generally added to the raw materials for making insulation bricks. Coal gangue needs to be crushed by a hammer crusher before use. In general, the crusher crushes incoming materials regardless of their size, which increases the difficulty of crushing. At present, there is a lack of a A step-by-step crushing device; in addition, the crushed raw materials need to be screened, and additional equipment is required to complete, which increases the investment in equipment and increases the production cost; in addition, when the raw materials are mixed with iron impurities, the crushing device will Cause more serious damage, thereby reducing the service life of the device
