How to distinguish roller sand making machine and rod sand making machine?
For a long time, hard rock sand making, such as granite, basalt and pebbles, has been a crushing problem in the sand and stone industry. Because these rocks generally contain too much silicon and have high hardness, the traditional sand making method has too much wear cost, and the other is that the effect is not ideal. Later, Shandong Sanxiang Heavy machinery according to the actual situation has developed a roll grinding sand machine and rod grinding sand machine is a good fill in this blank.
Roller sand making machine and rod sand making machine have obvious advantages in hard rock sand making, and now they have been generally recognized by the market, so what are the similarities and differences between the two? Let's talk briefly below:
Similarities:
First: Both can be used for soft rock and hard rock sand making, but in the soft rock crushing, the company's previous research and development of the impact plate hammer sand machine has insufficient advantages, its advantages are mainly reflected in the hard rock sand making.
Second: the wear cost of the two for hard rock sand making is generally greatly reduced, and compared with the impact sand making machine, there are advantages of low energy consumption, large output and low maintenance cost.
Third: the main role of the two in the stone crusher production line is to make sand, only suitable for fine breaking work, too large material has a great impact on the efficiency of the two, so in the actual use of the process, to use the amount.
The difference:
First: They work differently. The roller mill mainly relies on the double roll extrusion pressure to break the relevant materials, and the rod sand mill uses the centrifugal force generated by the rotation of the cylinder to drive the steel rod and the material to produce friction to break, but the two have the same effect, avoiding the principle of direct impact, relatively speaking, it protects the wear degree of the wear-resistant parts of the machine.
Second: the cost of investment is different. The initial investment cost of the same production roller sand mill is relatively large, and the roller sand mill is relatively small, but it can not be used to judge the advantages and disadvantages of the two.
Third: the cost is different in the later period. The two rollers of the roller grinding sand machine are made of high chromium and other wear-resistant materials, and there is almost no maintenance cost in the later production; Rod grinding sand machine needs to fill steel rods regularly, and the replacement cost of parts is significantly less than the former.
In summary: Shandong Sanxiang Heavy Industry Co., Ltd. for the hard rock sand production of roller grinding sand machine and rod grinding sand machine between the oil similarities, and there are obvious differences, but they have a good solution to the current hard rock sand production of the old difficult problem. If you have this demand, welcome to the field inspection of the on-site production effect of two kinds of machines, Shandong Sanxiang Heavy machinery can according to your actual requirements, the nearby arrangement of old customers to visit the production site.
