The quartz sand crusher (roller crusher) is driven by two motors to operate two rollers. The quartz sand making machine mainly crushes and grinds materials, and is mainly suitable for the medium and fine crushing of medium hard materials.
In order to obtain products with different strength, the discharge port size of the quartz sand crusher (roller crusher) must be adjustable. In order to prevent iron damage to the crusher, a safety device must be installed. The movable roller shaft of the quartz sand making machine is supported by spring pressure. Under normal working conditions, the spring force is sufficient to overcome the crushing force required for the crushed material. Different thicknesses of gaskets are placed between the frame and the movable bearing. By changing the number of gaskets, the width of the discharge port between the two rollers can be adjusted to meet the requirements of different product particle sizes. When materials that cannot be crushed enter the crushing chamber, the spring is compressed, and the movable roller retreats to increase the discharge port. After the materials are discharged, the movable roller returns to its original position under the pressure of the spring. This is the mechanical discharge port adjustment and overload protection device (safety device).

Advantages of quartz sand crusherIn recent years, quartz sand crushers (roll crushers) have been widely used to crush steel slag. The steel slag crushed by quartz sand crushers (roll crushers) greatly reduces the grinding cost of ball mills and improves the economic benefits of steel slag selection. In Zhejiang and Jiangsu stone factories, quartz sand crushers (roll crushers) are also used for sand production. If the stone you crush is relatively hard, it is recommended that you first consider using quartz sand crushers (roll crushers) for crushing, because quartz sand crushers (roll crushers) have very few vulnerable parts, except for the roll skin, there are no other vulnerable parts. However, other crushing equipment needs to replace vulnerable parts every few days when crushing materials with higher hardness, greatly increasing time and economic costs. And our company's quartz sand crusher (roller crusher) uses high manganese steel integral casting roller skin, all of which have undergone heat treatment. The roller skin produced in this way has a lifespan two to three times longer than ordinary roller skin.

1. Equipping a PDG-II roller sand making machine in the grinding system can fully utilize the production capacity of the grinding equipment, generally increasing output by 30% -40% and reducing total energy consumption by 20% -30%.
2. The quartz sand crusher (roller crusher) has a compact structure, light weight, and small volume. For grinding systems with the same production capacity requirements, equipping a PDG-II roller crusher can significantly save investment.
3. The quartz sand making machine has a simple structure, occupies a small space, and is easy to operate and maintain.
4. Internally equipped with dust-proof plates, the sealing performance is good, avoiding the splashing of small materials after crushing, reducing dust, low working noise, and greatly improving the working environment.
5. The abrasive roller body has been re optimized and designed, and the equipment does not need to replace the grinding roller body for life, while the old type of roller machine needs to be disassembled and overhauled after one year of use, and the roller body needs to be replaced.
6. The grinding roller of the quartz sand crusher is equipped with replaceable wear-resistant lining plates, which are made of advanced wear-resistant materials in China and have the advantages of long service life, low damage, and easy maintenance. The continuous service life can reach more than one year. When the wear is severe, the hood can be removed for replacement. The maintenance volume is small and the cost is low, which is incomparable to any other type of crusher in China.
7. The quartz sand making machine is equipped with a safety protection device. When unexpected metal or iron parts enter the crushing chamber, the protection device will be activated, and the iron parts will leak out and the equipment will operate normally.
8. The gap between the abrasive roller body of the quartz sand crusher can be adjusted arbitrarily between 1mm and 20mm. After adjusting the roller gap according to the requirements of the crushing particle size, the crushing particle size can be reliably controlled and discharged from below the crushing chamber at the ideal particle size.
9. The structure is simple and reasonable, with low operating costs, smooth operation, high efficiency and energy saving, high crushing efficiency, and adjustable discharge particle size.
10. The quartz sand making machine operates on the principle of low-speed and high-pressure roller extrusion. The material falls vertically into the crushing chamber from the upper part of the crusher, and is crushed by the strong pressure generated between the two rollers. Most of the material has become powder, and the remaining small portion of granular material has already produced a large number of cracks inside. In the further crushing process, the energy consumption of grinding can be greatly reduced and the output can be increased.
Note: When customers require finer fineness and higher output for crushed materials, a four roll crusher can be considered.
