Double Roller Crusher Machine For Sand Making

The double roller sand-making machine, also known as a roller crusher, is a mining machinery that integrates various technologies. It performs fine crushing and sand-making operations. This machine has a reasonable structure, small size, and high efficiency, which make it popular. However, is the sand produced by the roller sand-making machine good? How do we adjust the particle size?

Double roller crusher Introduction

Material crushing is a fundamental and crucial step in the industrial field. As an essential crushing equipment, the roller crusher has become indispensable in many industries due to its excellent adaptability and crushing performance.

Working principle

The working principle of a roller crusher is like two huge rollers that rotate and generate pressure on each other, gripping, squeezing, and ultimately crushing materials. This process is similar to the ancient method of grinding stone, but the power and efficiency of the roller crusher far exceed the imagination of ancient people. The material is compressed between two rollers until it reaches the desired particle size and then discharged from the machine. The efficiency of this process benefits from the design of the roller crusher.

Features

  • The design advantage of this machine is that the roller surface of the roller crusher is customizable based on the material characteristics. Choose the roller surface of the roller crusher with different materials and patterns based on the hardness, humidity, and other characteristics of the crushed material. This customized design enables the roller crusher to handle various materials ranging from soft coal to hard ore.
  • Furthermore, the adjustment system of the roller crusher is flexible and can control the particle size of the crushed material by adjusting the distance between the rollers. Users can easily obtain products of different granularities according to their production needs. The precision of this adjustment mechanism ensures the roller crusher’s adaptability in various crushing scenarios.
  • Many crushing equipment do not work well when facing high-humidity materials, but the double-roll crusher is suitable. The unique design makes it less prone to clogging when handling wet and sticky materials. The environmental performance of roller crushers is good. The dust and noise generated during the crushing process are relatively low. It helps improve the working environment and aligns with sustainable development.

  • The performance of the roller crusher in practical application is equally outstanding. Whether coal mining enterprises need to crush a large amount of coal, the building materials industry needs to deal with hard rocks or chemical enterprises face special crushing problems, roller crushers can provide solutions. They are highly adaptable and can handle any challenge with ease. The roller crusher can effectively avoid the troubles caused by wet materials.

Is the sand produced by the roller sand making machine effective?

Yes, it is effective.

  • The final sand has uniform particle size, low over-crushing rate, low needle-like content, and no internal cracks. In addition, the particle size distribution, mud block content, stone powder content, crushing index, apparent density, bulk density, and other technical indicators meet the requirements of construction sand, and the overall effect is still good.
  • The roller sand-making machine uses two opposite rotating rollers to crush materials. It is suitable for various brittle and high-hardness materials such as river pebbles, limestone, quartz, coal gangue, etc. The feed particle size is large, and the discharge particle size is around 2-10mm, which is adjustable.

How to adjust the discharge of the roller Crusher machine?

The thickness of the discharge particle size of the roller sand-making machine equipment is adjustable by adjusting the wedge or gasket device installed between the two rollers. 

  1. The top of the wedge device is equipped with an adjusting bolt. When the adjusting bolt pulls up the wedge, the wedge pushes the moving roller away from the fixed roller, that is, the gap between the two rollers increases, and the discharge particle size increases. When the wedge is pressed downwards, the gap between the two rollers decreases under the action of the compression spring, and the particle size decreases accordingly.
  2. The particle size is adjustable by increasing or decreasing the number or thickness of washers. When the grommet grows, the gap between the two rollers becomes larger. If the washer decreases, the gap between the rollers becomes smaller, resulting in a smaller particle size discharged.

Advantages and disadvantages of roller sand making machine

Advantages
  • Through roller design, the strong pressure generated between the two rollers and the raw materials squeeze and crush into powder and granular forms, overcoming the challenges of working with both dry and wet materials.
  • Select energy-saving motors to save energy consumption under the same production capacity, integrate intelligent control technology, and achieve automated operation.
  • The roller skin’s wear cycle is long, and the roller crusher adopts a new type of high-strength and wear-resistant material for crushing high-hardness materials with low loss and long service life.
  • The work noise is low, the sealing is good, and there is a dust removal device to eliminate dust pollution, which meets environmental standards.

Disadvantages

The feed particle size cannot be too large, which may result in not eating the material. Compared to other sand-making products, it has lower processing capacity and requires uniform and continuous feeding, making it suitable for small and medium-sized enterprises.

How much is a roller sand-making machine?

Comparatively speaking, it is not high for the price of roller sand-making machines. It shows differentiation, which is affected by many factors, related to model selection, and there are many equipment manufacturers in the market, with different products in various aspects.
