Hard material sand making process

 1. Feeding and coarse crushing

1. Use a vibrating feeder to evenly feed hard materials into the coarse crushing equipment.

2. Use a jaw crusher for coarse crushing. The jaw crusher is suitable for primary crushing of hard materials. Materials with a feed size of less than 1200mm can be crushed, and the processing range is wide.

2. Medium and fine crushing and screening

1. The coarsely crushed materials are transported by conveying equipment to the medium and fine crushing equipment for further crushing. For hard materials, cone crushers are usually used for secondary crushing.

2. The crushed materials are screened, and the materials that meet the requirements enter the next process, and the materials that do not meet the requirements are sent back to the crusher for re-crushing.

3. Sand making and shaping

1. Use a sand making machine to crush and shape the screened materials. For hard materials, the vertical shaft impact crusher has a better crushing effect, and the processed materials have a more uniform particle size.

2. In order to improve the sand formation rate, control the fineness modulus and stone powder content, the rotor speed of the sand making machine, the feed grading and other parameters can be adjusted.

4. Screening and sand washing

1. Use a vibrating screen to screen the finished sand after sand making, which is usually divided into coarse sand, medium sand and fine sand.

2. In order to obtain clean finished machine-made sand, a sand washing machine can be equipped for sand washing. The commonly used sand washing equipment is a wheel bucket sand washing machine, and the sand particles after washing have good shape and high quality.

5. Auxiliary equipment and dust removal

1. In the sand making process, auxiliary equipment such as belt conveyors and dust removal equipment are also required to ensure the smooth operation of the production line and environmental protection requirements.

2. Dust removal equipment can effectively reduce dust pollution and protect the environment and workers' health.

In summary, the hard material sand making process includes feeding and coarse crushing, medium and fine crushing and screening, sand making and shaping, screening and sand washing, and auxiliary equipment and dust removal.

The difference and characteristics between sea sand and river sand

 River sand is cement standard sand, which is mostly used in construction, concrete, cementitious materials, road construction materials, artificial marble, cement physical properties test materials (i.e. cement standard sand), etc. Sea sand is the main raw material for machinery and foundry sand, grinding materials (sandblasting, hard grinding paper, sandpaper, emery cloth, etc.). At present, one of the main uses of sea sand is as a filler for engineering construction, especially land reclamation projects. How to distinguish sea sand from river sand? Xingaonai will compare you from 4 aspects.

1. Compare from the specifications

The river sand used in construction has certain specifications. In the process of river sand screening, it is generally divided into river sand 4-8 mesh, river sand 8-16 mesh, river sand 10-20 mesh, river sand 20-40 mesh, river sand 40-70 mesh, river sand 50-100 mesh, etc. This refers to the number of sand particles within a one-inch circular range. Sea sand does not have such a fine and clear rule classification.

2. Difference in the feel

Grab a handful of sand and hold it in your hand and pat it off. If you find that it is sticky and you can't pat it clean, it is sea sand, which has a sticky feel. If it is not sticky, it is river sand.

3. Difference in taste

This is the simplest and stupidest way. Taste it and find that it is not salty if it is river sand, and salty if it is sea sand. At present, there are also many sea sands that have been desalinated. We can soak the sand in water for a period of time and taste the water. The salty and astringent one is sea sand.

4. Difference in ingredients

The main component of sea sand is silicon dioxide, the crystal phase is mainly quartz, the feldspar and rock debris particles are relatively small, the content of mica flakes is even less, and the roundness is also very good. The silicon content of river sand is lower, and the metal ions such as calcium and aluminum are more, and the content of mica flakes will be a lot. But this is just the overall average situation, sometimes there are exceptions, and it is difficult to have specific quantitative indicators. The Ministry of Construction pointed out in the regulations on the management of construction sand that sea sand must be purified to meet the requirements before it can be used. For reinforced concrete, the chloride ion content of sea sand should not be greater than 0.06%. However, in order to save costs, many construction units currently use sea sand that has not been desalinated. Therefore, when buying sand, you must carefully identify it to avoid being deceived.

How to choose crusher equipment correctly and effectively

 The following key factors need to be considered to correctly and effectively select crusher equipment:

Material properties:

Hardness: Different types of materials have different hardness. The greater the hardness, the higher the crushing difficulty coefficient.

Specifications and particle size: When the material specifications are large, a jaw crusher can be selected as the primary crushing; when the stone specifications are small and need to be composed of a certain grade of stone, a combined crushing and screening equipment is required.

Water content: The water content of the material will also affect the selection of the crusher. When the water content is too high, the fine-grained material will agglomerate or stick to the coarse-grained material due to the increase in humidity, thereby increasing the viscosity of the material, reducing the discharge speed, and reducing productivity.

Abrasiveness: Materials with strong abrasiveness are generally crushed, and the surface of the crushing tool is smooth; materials with weak abrasiveness are crushed by impact, impact, grinding, etc.

Tough materials are generally sheared or struck quickly, such as hammer crushers.

Powdered or muddy materials should be ground, impacted or crushed, such as ball mills.

Production requirements:

Inlet and outlet particle size: The inlet and outlet particle size is used to determine the model and crushing level of the required crushing equipment.

Output and efficiency: According to the actual needs and scale of the production line, select a crusher that can meet the requirements of output and efficiency.

Equipment performance:

Energy consumption: Under the condition of meeting the process requirements, select crusher equipment with low energy consumption.

Wear resistance: The service life of the wear-resistant parts of the crusher is particularly important, so equipment with good wear resistance should be selected.

Maintenance and maintenance: The maintenance and maintenance costs of the equipment are also factors that need to be considered. Equipment with easy maintenance and long maintenance cycles should be selected.

Price and budget:

Equipment price: Select appropriate equipment according to the budget range, but price is not the only determining factor.

Cost-effectiveness: Consider the performance, quality and price of the equipment comprehensively, and select equipment with high cost-effectiveness.

Manufacturer qualifications and brands:

Select equipment produced by manufacturers with advanced technology, reliable qualifications and excellent brands to ensure the quality and after-sales service of the equipment.

Practical inspection and testing:

Before purchasing, it is best to inspect the manufacturer and production line of the equipment on site to understand the actual operation and performance of the equipment.

If conditions permit, actual tests can be carried out to verify whether the equipment meets production requirements.

In summary, the correct and effective selection of crusher equipment requires comprehensive consideration of multiple factors such as material properties, production requirements, equipment performance, price and budget, and manufacturer qualifications and brands.
