Concrete batching fpr Sieving Machine

Concrete batching fpr sieving machineis a kind of equipment used to screen and batch raw materials (such as sand, gravel and other aggregates) in the concrete production process. Its main function is to screen concrete raw materials (such as sand and gravel) to ensure that their particle size meets the standard. It plays a key role in concrete mixing plants or production lines, ensuring that aggregates are separated and supplied according to specific particle sizes and proportions, thereby ensuring the quality and performance of concrete.

Working principle of concrete batching fpr sieving machine

The working principle of concrete batching fpr sieving machine usually involves the following steps:

①Feeding: Put the concrete aggregate to be screened into the feed port of the screening machine.

②Screening: The aggregate is graded according to the particle size through the screen. The design of the screen usually has sieve holes of different sizes to ensure that aggregates of different sizes can be effectively separated.

③Collection: The screened aggregates are collected in different containers for subsequent use.

What types of concrete batching fpr sieving machines are there?

Vibrating screen type: high screening efficiency and high precision, can effectively separate materials of different particle sizes, suitable for concrete production of various scales.

Drum screen type: simple structure, stable operation, large processing capacity, often used in large concrete mixing plants and sand and gravel yards.

Spiral screen type: combines the functions of spiral conveying and screening, can grade and screen materials, and is widely used in some specific concrete batching scenarios.

Functions of concrete batching fpr sieving machine

1. Screening: Aggregates of different particle sizes are separated through vibrating screens or other screening devices to remove impurities or materials that do not meet specifications.

2. Batching: Accurately measure the amount of various aggregates according to the concrete mix ratio requirements, usually used in conjunction with an electronic weighing system.

3. Automation: Modern concrete batching fpr sieving machines are mostly equipped with automated control systems to improve production efficiency and reduce manual operation errors.

What are the advantages of concrete batching fpr sieving machine?

Solve the problem of too many impurities in raw materials: the raw materials may contain impurities such as mud, leaves, plastic, etc., which will reduce the quality of concrete. Concrete batching fpr sieving machine can effectively remove impurities during the screening process to ensure the purity of the raw materials.

Solve the problem of uneven raw material particle size: the particle size distribution of raw materials such as natural sand and gravel is often uneven. Concrete batching fpr sieving machine separates the raw materials according to the particle size through screens of different specifications to ensure that the particle size distribution is within the required range.

Solve the problem of excessive raw material humidity: raw materials with excessive humidity are prone to adhesion, resulting in reduced screening efficiency and even clogging the screen. Concrete batching fpr sieving machine adopts a special screen design and vibration method to reduce material adhesion.

Solve the problem of insufficient large material processing capacity: when processing large materials, the screening machine may have problems such as blockage and overload. Concrete batching fpr sieving machines usually use larger feed ports and spacious screening channels to allow large materials to enter and pass through the screening machine smoothly.

Application of concrete batching fpr sieving machine

1. Commercial concrete mixing station: Concrete batching fpr sieving machine will classify the sand and gravel raw materials transported from the quarry (such as 0-5mm sand, 5-20mm crushed stone, 20-40mm large stones) and remove oversized particles or impurities (such as soil and branches).

2. On-site mixing station in highway construction: Concrete batching fpr sieving machine screens the crushed stone raw materials mined or transported on-site into specific particle sizes (such as 3-10mm, 10-20mm), removes powder or fine particles, and avoids loose base. According to the designed ratio (such as cement: sand: crushed stone = 1:2:3), it is automatically measured and transported to the mixer. .

3. Large-scale water conservancy projects (such as dam construction): Strictly control the aggregate particle size and gradation to ensure the density of concrete. For example, fine powder <0.15mm is screened out to reduce shrinkage cracks.

4. Urban subway tunnel shield construction: Concrete batching fpr sieving machine screens out fine aggregate with a particle size of <10mm and removes oversized particles to prevent the sprayer from clogging. Accurately measure sand, cement and additives (such as accelerators) to ensure that the sprayed concrete solidifies quickly and has strong adhesion.

5. Rural small prefabricated component factory: Concrete batching fpr sieving machine processes river sand and crushed stone, removes soil and oversized stones, and ensures a smooth surface of prefabricated parts. Small batch batching, meeting simple proportions (such as 1:2:4), suitable for manual or semi-automatic production.

Concrete batching fpr sieving machine is one of the indispensable equipment in concrete production. It provides a strong guarantee for concrete batching through efficient and accurate screening operations.
