The clay green sand treatment system consists of old sand treatment (crushing, magnetic separation, screening, drying, cooling, regeneration), storage and transportation systems; New sand treatment (drying, screening), storage, and conveying system; Additive storage and transportation system; Sand mixing (including quantitative addition of various materials) and conveying system; Online monitoring and control system for molding sand quality; Mechanized transportation electrical interlocking control system, etc

Sand treatment mainly includes the preparation of raw materials, the treatment and reuse of old sand, as well as the preparation of molding sand and sand cores. If new sand is mixed with impurities or has a high water content during transportation, it needs to be dried or screened. The old sand after falling out contains impurities such as hard sand balls, core blocks, crushed iron, and broken pouring and riser. The increase of dry sand and dust results in uneven composition, moisture, and temperature. Therefore, it is necessary to crush, screen, and magnetic separation and cooling the old sand to separate various impurities and homogenize its performance.

The preparation of molding sand and sand cores is the central link in the sand treatment system. The molding sand configured according to a certain composition is mixed in a sand mixer to meet the quality requirements, and then sent to the molding and core making department for use. To complete the above tasks, it is necessary to have many processes for processing raw materials, old sand, and molding sand, as well as various transportation equipment and auxiliary devices to connect the process equipment to form a sand treatment system.

The sand treatment system has a complex process, a large amount of processing and transportation workload, a wide variety of equipment, easy to generate dust, and poor labor conditions. Therefore, achieving automation of the sand treatment system, coupled with the control and management of the processing process, can not only provide qualified molding sand and core sand to improve the quality of castings, improve labor productivity, save energy and resources, but also protect the environment and improve labor conditions.

The basic raw materials for sand mold manufacturing are casting sand and molding sand binder*** The commonly used casting sand is siliceous sand. When the high-temperature performance of silica sand cannot meet the usage requirements, special sand such as zircon sand, chrome iron ore sand, and corundum sand are used. To ensure that the sand mold and core produced have a certain strength and do not deform or damage during transportation, molding, and pouring of liquid metal, it is generally necessary to add sand binder in the casting to bond loose sand particles into sand. The sand binder used is clay, and various dry or semi dry oils, water-soluble silicates or phosphates, and various synthetic resins can also be used as sand binders. The external sand molds used in sand casting are divided into clay wet sand molds based on the different binders used in the molding sand and the way they establish strength.

Clay wet sand mold uses clay and an appropriate amount of water as the main binder for molding sand. After making the sand mold, it is directly molded and poured in the wet state. Wet mold casting has a long history and is widely used. The strength of green sand depends on the clay slurry formed by mixing clay and water in a certain proportion. Once mixed, the molding sand has a certain strength, and after being compacted into a sand mold, it can meet the requirements of molding and pouring. Therefore, the amount of clay and moisture in the molding sand are very important process factors. Customized equipment configuration.

Sand grinding machine, sand mixing machine, coated sand production line, clay sand regeneration equipment, resin sand regeneration equipment, drying equipment, water glass is regeneration, clay sand production line, resin sand production line, double arm sand mixer, mobile sand mixer, belt conveyor, bucket elevator, ring chain bucket elevator, plate chain bucket elevator, vibration sand falling machine, sand falling drum, vibration conveyor, rotor regeneration machine, dust collector, shot blasting machine, regeneration equipment

The clay sand production line is an important part of casting production, and its task is to provide qualified molding sand and sand cores for the molding and core making department. The quality of mold (core) sand preparation directly affects the improvement of casting production quality and output, as well as the reduction of * * *.

The significance of clay sand regeneration

1. In terms of molding sand: effectively remove micro particles such as dead clay in the molding sand; Reduce the amount of moisture added to the molding sand; Make the distribution and particle size distribution of molding sand more uniform; Reduce the pollution of new sand on molding sand and control the total amount of ceramic coating;

Reduce the amount of new sand added; The temperature of the molding sand is reduced;

2. In terms of casting quality: improving surface smoothness; Reduce scrap rate;

The sand treatment system mainly consists of sand falling, screening and cooling, old sand storage and regeneration, sand mixing unit, lifting and conveying, dust removal system, and electrical control system.
