Abstract

The invention discloses an abrasive material recycling method. The abrasive material recycling method comprises the following steps of: (1) collecting, cleaning a work site, collecting all the garbage, and storing the garbage in a dry storeroom; (2) removing a binding agent, namely soaking the garbage containing brown aluminium oxide, the binding agent and finely ground iron scrap in a container with clear water, hydrolyzing dried binding agent, placing papescent matter after being hydrolyzed into the container, adding water and stirring, dumping water containing the binding agent after the binding agent is fully diluted, and repeatedly flushing for several times until the binding agent is cleaned; (3) drying and carrying out roughing separation, namely uniformly spraying the mixture of cleaned brown aluminium oxide or white corundum iron scrap and sundries on the ground, drying in the sun, and removing major sundries by adopting a sieve after drying; (4) carrying out magnetic separation, namely separating the iron scrap by adopting a magnetic separation machine while only the brown aluminium oxide or white corundum is remained; and (5) carrying out granularity separation, namely screening the brown aluminium oxide or white corundum with nonuniform granularity, dividing into standard granularities and respectively packaging. The abrasive material recycling method disclosed by the invention is simple in operation, safe and reliable, investment and cost are low, and the recycled product is good in quality and can be repeatedly used and repeatedly recycled.

Description

A kind of recovery method of abrasive material

Technical field

The invention belongs to the recovery method of Industry Waste rejected material, specifically a kind of recovery method of abrasive material.

Technical background

In the prior art, a lot of hardware enterprise uses brown corundum, white fused alumina to grind material as polishing in a large number, generally, uses gelatin or waterglass (flower bulb alkali) as adhesive, brown corundum or white fused alumina is bonded at cloth takes turns, and carries out polishing.In polishing process, most of brown corundum or white fused alumina particle are not done manual work, do not contact workpiece, but because adhesive is insecure, split away off on the cloth wheel with bulk, become industrial refuse, only have a small amount of brown corundum or white fused alumina particle in polishing process, with Work piece high-speed friction, shock, self fragmentation, become less particle and become rubbish, be not recovered utilization all the time.

Summary of the invention

Purpose of the present invention is to overcome the deficiencies in the prior art part, and a kind of recovery method of abrasive material is provided, and it can reclaim abrasive material well, and input re-uses, and has solved the waste problem of abrasive material, for processing enterprise saves cost.

For achieving the above object, the present invention takes following technical scheme: the recovery method of a kind of abrasive material of the present invention is taked following steps:

1. collect, the work-yard is cleaned, collect all rubbish, leave in dry storehouse;

2. remove adhesive, the rubbish that will contain brown corundum, adhesive, iron filings in small, broken bits is put into container and is soaked with clear water, dry adhesive hydrolysis, atherosclerotic thing after hydrolysis is put into container, add water and stir, after adhesive is fully diluted, outwell the water that contains adhesive, so rinse for several times, till cleaning adhesive;

Dry, roughly select, brown corundum or white fused alumina bushel iron bits and foreign material mixture with wash clean all spill on the ground, dry get final product, Sai does afterwards and removes larger foreign material with sieve;

4. magnetic separation is separated iron filings with magnetic separator, only remaining brown corundum or white fused alumina;

5. size sorting, the brown corundum that granularity is inhomogeneous or white fused alumina are divided into standard particle size by screening, and packing gets final product respectively.

The present invention takes technique scheme, has following beneficial effect: the recovery method of a kind of abrasive material of the present invention, and simple to operate, safe and reliable, drop into lowly, cost is low, and the good product quality of recovery is reusable, repeats to reclaim.

The specific embodiment

Below in conjunction with embodiment, the present invention is described in detail.

Embodiment

1. collect, the work-yard is cleaned, collect all rubbish, leave in dry storehouse Guard against damp in;

2. remove adhesive, the rubbish that will contain brown corundum, adhesive, iron filings in small, broken bits is put into cement pit or other larger container, add clear water to soak more than 12 hours, make dry adhesive hydrolysis, the atherosclerotic thing after hydrolysis is put into less container, add water and stir, after adhesive is fully diluted, outwell the water that contains adhesive, so rinse for several times, till cleaning adhesive;

Dry, roughly select, the brown corundum of wash clean or white fused alumina bushel iron bits and foreign material mixture, all be sprinkled upon on the cement flooring, dry and get final product, The faster the better for dry speed, the variable color in case iron filings get rusty, Sai does and removes larger foreign material with sieve afterwards;

4. magnetic separation, after with magnetic separator, iron filings being separated, only remaining brown corundum or white fused alumina;

5. size sorting, inhomogeneous by the brown corundum after magnetic separation or white fused alumina granularity, by screening, is divided into standard particle size, respectively packing.

Claims

1. the recovery method of an abrasive material, it is characterized in that it takes following steps: collect (1), and the work-yard is cleaned, and collects all rubbish, leaves in dry storehouse; (2) remove adhesive, the rubbish that will contain brown corundum, adhesive, iron filings in small, broken bits is put into container and is soaked with clear water, dry adhesive hydrolysis, atherosclerotic thing after hydrolysis is put into container, add water and stir, after adhesive is fully diluted, outwell the water that contains adhesive, so rinse for several times, till cleaning adhesive; (3) dry, roughly select, brown corundum or white fused alumina bushel iron bits and foreign material mixture with wash clean all spill on the ground, dry get final product, Sai does afterwards and removes larger foreign material with sieve; (4) magnetic separation is separated iron filings with magnetic separator, only remaining brown corundum or white fused alumina; (5) size sorting, the brown corundum that granularity is inhomogeneous or white fused alumina are divided into standard particle size by screening, and packing gets final product respectively.
