Which is better, PCL sand making machine or VSI sand making machine?

19/06/2021

With our country’s familiarity with artificial sand technology, the current sand making machine technology has been developed from the PCL impact crusher to the fifth and sixth generations of VSI sand making machines. Compared with the traditional PCL sand making machine, which aspects of the new VSI sand making machine have been improved, and what is the effect? Let’s take a look!

1. Different feeding methods
PCL is the central feed. VSI has two types: complete central feed and central feed with annular waterfall feed. VSI5X (fifth generation sand making machine) uses a bulk tray device, which can quickly realize central feed and waterfall The conversion of falling feed reduces downtime adjustment time and improves efficiency. VSI4X (fourth generation sand making machine) adopts bulk material cone device, which can realize complete center feeding by removing the bulk material cone.

In addition to two feeding methods for VSI sand making machine: complete center feeding and center feeding with waterfall feeding, there are also two crushing methods: “stone hitting stone” and “stone hitting iron”. “Stone hitting stone” is suitable for plastic surgery, and “stone hitting iron” is suitable for sand making.

2. The wear resistance of wearing parts is different
The single feeding method of the PCL sand making machine determines its short life of wearing parts, while the VSI is different:

1) With its two-phase feeding method, the wearing parts have a longer working life and higher economic benefits;

2) The optimized arrangement design of its wear-resistant materials increases the service life by more than 40% and reduces the cost by more than 40%;

3) During the production process, the stone can form a protective bottom layer, the machine body is also less worn and durable.

3. Different lubrication system

PCL uses a dry oil lubrication system, which has a poor heat dissipation function, which greatly reduces the service life of the spindle bearing and increases the maintenance cost. The VSI sand making machine adopts a light oil lubrication system, which can effectively dissipate heat during the operation of the spindle bearing, ensuring that the temperature rise is within 25°C and extending the service life of the bearing. The light oil system can effectively lubricate and reduce bearing friction during the working process, and increase the bearing speed, thereby greatly improving work efficiency.

4. The production process is different
PCL uses a profile welding process, which is simple to produce and select materials and has poor structural strength. VSI uses a steel plate bending hot rivet process. The appearance of the machine body is more environmentally friendly, enhances the structural strength and toughness of the equipment, and ensures the smooth operation of the equipment. Make the quality rise to a whole new level.

5. Different product grain types
With the gradual development of machine-made sand technology, the VSI sand making machine is less affected by the moisture content of the material, up to 8%, and its product has excellent grain shape, cubic shape, extremely low needle flake content, high bulk density, and low iron pollution , It is suitable for aggregate shaping, artificial sand making and high-grade highway aggregate production. The sand produced has reached the national standard sand standard in terms of gradation and fineness modulus.

6. Different environmental protection effects
The traditional PCL sand making machine does not consider too many environmental factors. In recent years, with the expansion of the scope of environmental protection supervision and the strengthening of environmental pollution penalties, the VSI sand making machine is designed to better meet the current market requirements. Because it belongs to the broken cavity, there is little dust pollution and low working noise.

In the current market, traditional PCL sand making machines are favored by users due to their low price and large production capacity. However, in summary, we can see that compared with traditional PCL sand making machines, advanced VSI sand making machines are environmentally friendly and energy-saving. , Long service life, low maintenance cost and high production efficiency. With increasing environmental protection efforts, VSI sand making machines have become mainstream products in the domestic machine-made sand field, promoting green production.

One thing to note is that the PCL series mentioned in this article is a traditional sand making machine product. It has been widely used from 1990 to 2007. At present, there are also manufacturers who develop new sand making equipment on the original basis. PCL is still used. The series are named and must be distinguished.
