Pneumatic conveying of molded sand

The basic physical and chemical properties of

sand mainly include: particle size distribution, density, water content, air permeability, strength, binder content, etc. The particle size distribution affects the fluidity and filling properties of the molded sand. Density affects the compactness and strength of the molding sand; The water content affects the cohesion and fluidity of the molding sand; Air permeability affects the casting performance of molding sand; The strength affects the reusability of the molding sand; The binder content affects the bond strength and high temperature resistance of the molding sand. Common conveying methods of molding sand include: belt conveying, spiral conveying, pneumatic conveying, vibration conveying, etc. When choosing a sand conveying method, it should take into account the characteristics of the material, the conveying needs, and whether there are other conveying needs. At present, the common sand conveying methods in the industry mainly include the following types: belt conveying is suitable for large quantities and long-distance transportation; Screw conveying is suitable for conveying viscous materials; Pneumatic conveying is suitable for occasions with long conveying distances and large conveying volumes. Vibration conveying is suitable for conveying materials with good fluidity.

1. Common conveying methods

The common transportation methods of

sand are mainly divided into mechanical conveying and pneumatic conveying. Mechanical conveying realizes the transfer of materials through the movement of mechanical components, which is a traditional conveying method and is suitable for short-distance, low-height, and small-flow scenarios. This method includes various types such as screw conveyors, bucket elevators, belt conveyors, and scraper conveyors, each with its specific principles and characteristics. Screw conveyors are suitable for conveying powdered materials, bucket elevators are suitable for vertical conveying of materials, belt conveyors are suitable for continuously conveying large quantities of materials, and scraper conveyors are suitable for conveying viscous or granular materials. Relatively speaking, pneumatic conveying uses airflow energy to transport materials in closed pipelines, which is the core technology in material processing, warehousing, and packaging, and selects the appropriate transportation method according to the characteristics of the material.

2. Can the sand be conveyed by pneumatics?

sand is very suitable for pneumatic conveying because of its fine particles, small density, good fluidity and no obvious adhesion, which is powered by compressed air or vacuum, and carries the material through the airflow in the closed pipeline and passes through the separator to achieve gas-solid separation. Pneumatic conveying can be divided into negative pressure suction type, positive pressure pressure pressure conveying type and mixed type according to the conveying pressure and power form, and usually adopts the dilute phase conveying method to ensure the rationality of gas-solid mixing concentration.

sand plastically conveying is an efficient sand conveying technology, which uses pneumatic force to transport sand from the sand treatment system to the mold making site, which has the advantages of fast conveying speed, high efficiency, small footprint, and easy operation. This technology mixes the molded sand and air into a pneumatic flow through a pneumatic conveying device, transports it to the destination by pipeline, and then separates the sand and air through a separator to achieve continuous and uniform transportation of molded sand, which is widely used in the sand treatment and transportation link of the foundry industry.
