In the field of infrastructure construction such as buildings, roads, and bridges, high-quality sand is an indispensable and important material. To process high-quality sand that meets the standards, a set of scientific and reasonable equipment combinations is required. The following is a detailed introduction to the key equipment and its functions.

Crushing equipment: laying the foundation for sand and gravel

Jaw crusher-pioneer of coarse crushing

Function: It is mainly used for the preliminary crushing of large pieces of stone, breaking large ores or rocks into smaller pieces, and providing suitable material particle size for subsequent crushing and sand making processes.

Features: It has the advantages of large crushing ratio, simple structure, reliable operation, and convenient maintenance. Its crushing chamber is deep and has no dead zone, which improves the feeding capacity and output; the use of high-quality wear-resistant materials prolongs the service life of the equipment.

Applicable scenarios: It is suitable for coarse crushing of ores and rocks of various hardness, such as granite, basalt, limestone, etc., and is often used as a primary crushing equipment in sand and gravel production lines.

Cone Crusher/Impact Crusher - Medium and Fine Crushing Tool

Cone Crusher

Function: Medium and fine crushing of materials after jaw crusher, further reducing the particle size of materials to make them closer to the particle size range required for sand making.

Features: Adopting the principle of lamination crushing, it has high crushing efficiency, low energy consumption, uniform product particle size and low needle-like content. Its hydraulic protection and hydraulic cavity clearing system can realize automatic overload protection and cavity clearing, reducing downtime.

Applicable scenarios: Suitable for crushing high-hardness materials such as iron ore, copper ore, granite, etc., and is often used in large-scale sand and gravel production lines and mining enterprises.

Impact Crusher

Function: Also used for medium and fine crushing, but more suitable for crushing medium and low hardness materials, crushing the materials through the impact of the plate hammer, and at the same time having a certain shaping effect on the materials.

Features: Large crushing ratio, good product particle shape, cubic, no tension and cracks; compact structure, strong machine rigidity, and large moment of inertia of the rotor, which improves production efficiency and crushing effect.

Applicable scenarios: commonly used for crushing limestone, gangue, shale and other medium and low hardness materials, and also widely used in construction waste treatment, machine-made sand production and other fields.

Sand making equipment: shaping high-quality sand shape

Impact sand making machine - core sand making equipment

Function: further processing the crushed materials into machine-made sand that meets the requirements, it is the key equipment for producing high-quality sand. It uses the two crushing principles of "stone hitting stone" and "stone hitting iron" to make the materials collide and rub against each other in the high-speed rotating impeller to crush, thereby obtaining machine-made sand with good particle shape and reasonable grading.

Features: high crushing efficiency and low energy consumption; the product has uniform particle size and rounded particle shape, which meets the national construction sand standards; the use of thin oil lubrication system can realize automatic maintenance and maintenance, reducing the operating cost and maintenance difficulty of the equipment.

Applicable scenarios: Widely used in fine and coarse grinding of various ores, cement, refractory materials, bauxite clinker, corundum, glass raw materials, machine-made building sand, stone and various metallurgical slags, especially for high-hardness, extra-hardness and abrasion-resistant materials such as silicon carbide, corundum, sintered bauxite, and fine sand. The output efficiency is higher than other types of crushers.

Screening equipment: Control the particle size of sand and gravel

Vibrating screen-precision classification expert

Function: Screen the materials after crushing and sand making, separate sand and gravel of different particle sizes, and ensure that the particle size of the final product meets the requirements. Through multi-layer screens, multiple specifications of products can be screened at the same time.

Features: high screening efficiency and large processing capacity; simple structure and easy maintenance; using advanced vibration motors or exciters, stable vibration and low noise.

Applicable scenarios: Suitable for screening operations of various materials, such as sand, gravel, ore, coal, etc., which plays a vital role in sand and gravel production lines. Vibrating screens of different layers and specifications can be selected according to different production needs.

Sand washing equipment: improve the quality of sand and gravel

Wheel bucket sand washing machine/screw sand washing machine-cleaning guard

Wheel bucket sand washing machine

Function: mainly used to clean soil, dust and other impurities in machine-made sand to improve the cleanliness and quality of sand and gravel. Through the rotation of the wheel bucket, the sand and gravel are brought into the water for mixing and washing, and then the washed sand and gravel are dehydrated and discharged through the dewatering screen.

Features: simple structure, stable operation; high cleaning degree, large processing capacity; low energy consumption, obvious water saving effect.

Applicable scenarios: suitable for cleaning machine-made sand of various particle sizes, widely used in small and medium-sized sand and gravel plants and construction sites.

Spiral sand washing machine

Function: Similar to the wheel bucket sand washing machine, it is also used to clean sand and gravel, but it has stronger cleaning ability, especially suitable for processing sand and gravel with large mud content and coarse particle size.

Features: good sealing performance, the transmission device adopts bearing and steel frame structure, long service life; large processing capacity and good cleaning effect.

Applicable scenarios: Commonly used for sand and gravel cleaning operations in large sand and gravel plants, mines, building materials and other industries.

To process high-quality sand, it is necessary to reasonably select and configure crushing, sand making, screening and sand washing equipment according to the nature of the material, production scale and product quality requirements to form a complete sand making production line.
