In recent years, the national capital construction has been vigorously developed, and the aggregate of sand and gravel is in short supply. Even in some places, due to the shortage of sand and gravel, some projects have been delayed and seriously hindered the development of the local economy. Now, the development of the sand and gravel industry is strongly supported by the national policy, and the investment potential of the sand and gravel industry is very large. However, due to the adjustable discharge grain size, the sand grain size is full, the grading is reasonable, and the over-crushing rate is low, With high output and no wearing parts, it is deeply favored by users. Users who have learned about the two-roller sanding machine know that the two-roller sanding machine is divided into spring type and hydraulic type, so which one is better? Here we recommend: hydraulic roller sanding machine. Huasheng Ming has more than 20 kinds of large, medium and small roller sanding machines. Our small models are spring type, and the medium and large models are hydraulic devices.


Spring roller sander and hydraulic roller sander need to readjust the pressure after using the spring roller sander for a period of time. The specific time of adjustment depends on whether the particle size of the product meets the requirements, and manual adjustment is required (hydraulic cylinder can be used to adjust the new semi-automatic hydraulic roller sander). The hydraulic twin-roll sanding machine can automatically compensate in the subsequent stages only by determining the pressure at the initial use, without secondary adjustment.


The roller sanding machine can be divided into large, medium and small sizes according to different models. 1、250 × 250，400 × 250，400 × 400，610 × 400750x500, with an annual output of about 2-50 tons, is a small spring-type double-roller sanding machine. 2、800x600,800 × 800，800 × 1000，1000 × 800，1000 × 1000，1200 × 1000，1200 × 1200，1500x1000，1500x1200，1800x1100,2000 × 1200 and above, 50-400 tons per hour, belonging to medium and large hydraulic roller sanding machine. According to the actual situation of each customer, Gongyi Huashengming Heavy Industry Machinery Factory divides the equipment into three types: high configuration, general configuration and low configuration. Customers can ask the sales manager to recommend the product type and performance suitable for them according to their actual situation.


The investment prospect of sand and gravel aggregate is still very optimistic by many people. With the more mature sand making technology, Huashengming Heavy Industry has become more and more stable in the performance of the equipment produced by the powerful manufacturers of roller sand making machines. There are more and more investors in roller sand making machines. In such a fierce market, it is also necessary to see the relationship between supply and demand in the market. Although there are many investors, for the manufacturers of mining machinery and equipment, Peer competition will also be more intense, so although the price of sand and gravel aggregate has risen again and again, the price of production equipment has not increased significantly
