Time : 07/03/2025

In the modern industrial and construction fields, the demand for manufactured sand is increasing day by day. As a key equipment for producing manufactured sand, the sand - making specifications and output of impact sand - making machines have attracted much attention. Understanding these aspects is of great significance for the reasonable selection of equipment, improvement of production efficiency, and guarantee of product quality.

I. Overview of Impact Sand - Making Machines

The impact sand - making machine, also known as the impact crusher, is a high - efficiency and energy - saving gravel equipment. It has a reasonable internal design, a novel appearance, and a wide range of applications. Its performance has reached the advanced level in the country. It is currently an effective, practical, and reliable gravel machine. This equipment is especially suitable for making abrasives, refractory materials, cement, quartz sand, steel sand, slag powder, copper ore, iron ore, gold ore, concrete aggregates, asphalt aggregates and other hard and brittle materials for fine and medium crushing.

II. Sand - Making Specifications of Impact Sand - Making Machines

(I) Feed Particle Size

Different models of impact sand - making machines have different requirements for feed particle size. For example, the VSI7611 impact sand - making machine allows a feed size of less than 30mm; the maximum feed particle size of the VSI8518 impact crusher is 40mm; the 5X9532 impact sand - making machine allows a feed size of less than 40mm for low - hardness materials and less than 45mm for higher - hardness materials; the feed particle size of the DLVSI1263 impact sand - making machine should be controlled below 50mm. Users need to select the appropriate model according to the particle size of their own materials to ensure the normal operation and high - efficiency production of the equipment.

(II) Discharge Particle Size

The discharge particle size of the impact sand - making machine can usually be adjusted according to actual needs. Generally, the discharge particle size range is relatively wide. Common discharge particle sizes are 0 - 5mm, 5 - 10mm, etc. For example, the discharge particle size of the VSI7611 impact sand - making machine is 5 - 10mm, 0 - 5mm manufactured sand, and stone powder; the discharge particle size of the 5X9532 impact sand - making machine is 0 - 5mm, with a high sand - forming rate. The proportion of particles below 3mm accounts for 80 - 85%, and the discharge ratio can be adjusted according to actual needs.

III. Output of Impact Sand - Making Machines

(I) Output Differences among Different Models

There are various models of impact sand - making machines, and the output of each model is different. Taking common models as examples:

(II) Factors Affecting Output

  1. Material Characteristics
    • Hardness: The harder the material, the more compact its crushing texture structure is, which makes sand - making more difficult, slows down the sand - making speed, and causes more serious wear and tear on the equipment, thus reducing the output. For example, when processing granite with high hardness, the output may be lower than when processing limestone with lower hardness.
    • Moisture Content: When the moisture content of the material is relatively large, the material is easy to adhere inside the sand - making machine, which can easily cause blockages in the discharge and conveying, reducing the output of the sand - making machine.
    • Viscosity: Materials with high viscosity will adhere to the inner wall of the flow - channel cavity of the sand - making machine, causing blockages in the flow - channel cavity, reducing the sand - making efficiency, and may even cause damage to the sand - making machine in severe cases, affecting the output.
    • Fine Powder Content: The more fine powder the material contains, the more likely it is to adhere during the sand - making process, which in turn affects the feeding and conveying speed and reduces the sand - making output.
  2. Feeding and Discharging Conditions
    • Feeding Amount: An excessive or insufficient feeding amount will not only reduce the sand output of the sand - making machine but also increase the wear of the lining plates in the crushing cavity, shortening the replacement cycle of the accessories. When the feeding amount reaches 70% - 90% of the full load of the impeller, the sand output can reach the peak.
    • Discharge Particle Size: The finer the required discharge particle size, the stronger the material's resistance to crushing, the more difficult the sand - making process, and the lower the sand - making capacity, resulting in a decrease in the output of the sand - making machine.
  3. Operating Conditions of the Sand - Making Machine
    • Impeller Rotation Speed: Under the same material characteristics, the higher the impeller rotation speed, the greater the kinetic energy. The materials are crushed by high - speed extrusion and grinding in the vortex cavity, and the output of the sand - making machine increases. Conversely, the output of the sand - making machine is lower.
    • Parameters and Models: The model and specifications of the sand - making machine, the installed power, the adjustable range of the rotation speed, the size of the discharge port, and the structure of the crushing cavity will all directly affect the efficiency of the sand - making machine.
    • Operation and Maintenance: Standard operation and regular maintenance of the sand - making machine can ensure and improve the sand output. On the contrary, the wearing parts of the sand - making machine will wear out faster, shortening the service life and resulting in a low sand output.
    • Equipment Configuration of the Sand - Making Production Line: The output of the sand - making machine should be consistent with the output of equipment such as jaw crushers, cone crushers, and belt conveyors on the sand - making production line. In this way, the sand produced by the sand - making machine can meet the requirements. Otherwise, it will also cause a low sand output of the sand - making machine.

IV. Reasonably Selecting Impact Sand - Making Machines to Meet Sand - Making Specifications and Output Requirements

(I) Selecting According to Material Characteristics

If the material has high hardness, high moisture content, or high viscosity, a model with strong processing capacity and good wear - resistance should be selected. At the same time, for materials with a large amount of fine powder, screening treatment can be carried out in advance to improve the output of the sand - making machine.

(II) Selecting According to Output Requirements

If a high output is required, a large - sized impact sand - making machine with strong processing capacity should be selected. For example, for a production demand of more than 200 tons per hour, models such as VSI8518, 5X9532, and DLVSI1263 can be considered. However, when making a selection, factors such as the price and energy consumption of the equipment also need to be considered.

(III) Comprehensively Considering Other Factors

In addition to sand - making specifications and output, factors such as the price of the equipment, maintenance costs, and ease of operation should also be considered. Choose a manufacturer with a good reputation and perfect after - sales service to ensure the normal operation and long - term stable production of the equipment.

In conclusion, the sand - making specifications and output of impact sand - making machines are affected by various factors. In actual production, users need to reasonably select the model of the impact sand - making machine according to their own material characteristics and output requirements, and do a good job in the operation and maintenance of the equipment to improve the sand - making efficiency and product quality and meet the market demand for manufactured sand.
