Production line of CA grinding material

Abstract

The invention discloses a production line of a CA grinding material. The production line comprises a belt mold, a transmission device, a slurry coating mechanism, a slurry scraping mechanism, a dryingmechanism, a material falling mechanism, a sweeping mechanism and a release agent coating mechanism, wherein the belt mold is provided with a cavity, the transmission device is used for driving the belt mold to run, the slurry coating mechanism is used for coating the surface of the belt mold and the inner part of the mold cavity with slurry, the slurry scraping mechanism is used for scraping theslurry coated on the surface of the belt mold into the cavity, the drying mechanism is used for drying the belt mold to enable the slurry to be dried and solidified to form grinding particles, the material falling mechanism is arranged below the drying mechanism and used for falling the abrasive particles in the belt mold cavity in an vibrating mode, the sweeping mechanism is used for sweeping slurry fragments of the belt mold after the material falls, and the release agent coating mechanism is used for spraying a release agent in a covering mode to the swept belt mold. According to the production line, six procedures such as the slurry coating, slurry scraping, drying, material falling, sweeping and release agent spraying are sequentially carried out, so that a set of circulating production line is formed, and the high automation of CA grinding particles production is realized.

Description

technical field [0001] The disclosure belongs to the technical field of abrasive production, and in particular relates to a CA abrasive production line. Background technique [0002] Ceramic corundum abrasive is a high-purity corundum abrasive with fine crystal structure synthesized by unique ceramic technology. There are two types of typical manufacturing processes, one is to use sol-gel process (that is, sol-gel process) to synthesize and manufacture through sintering. The specific method is: first make the raw material into a hydrosol, then gelatinize, then dry, pre-crumble, granulate, and sieve to form a certain particle shape and size, and finally make it into a high-quality product through calcination and sintering. Abrasives of toughness and hardness. The raw material can be boehmite or other aluminum media, and Fe can be added during the manufacturing process 2 o 3 and other nucleating substances to promote the formation of crystal nuclei and reduce the crystal t...

AI Technical Summary

Problems solved by technology

[0020] This method can obtain abrasives of various shapes, and the production efficiency is high, but the cost of laser cutting is high; the ceramic precursor material is broken along the score line to obtain abrasives, which will cause rough edges and poor integrity of the abrasives; Enables ceramic precursor material layers to be dried to the point that cracks (eg similar in appearance to mud cracks) begin to form at the peripheral area of ​​the layer, high operational difficulty; laser cutting replaces belt mold production, which provides ultrasonic vibration, threshing bars There is no specific structure for the combination of mechanisms or mechanisms such as blades, scrapers, etc., and the quality of blanking cannot be guaranteed
