Which one is better, rod mill sand making machine or vertical sand making machine?

With the depletion of natural sand resources and the increasing government control, it has become an inevitable trend for machine-made sand to replace natural sand. There are many equipment on the market that can be used to produce machine-made sand, among which rod mills and vertical sand making machines are particularly popular. , so which one is better, rod mill sand making machine or vertical sand making machine? Here are the answers for you:

Comparative introduction of rod mill sand making machine and vertical shaft sand making machine

Rod mill, also called rod mill sand making machine, is a small and medium-sized construction sand and stone production equipment with an output of 5-110 tons per hour. It crushes stones to make sand through the working principle of low-speed and high-pressure rod mill extrusion. The crushing particle size is good and the stone powder content is low. More importantly, it can also achieve sand making operations for stones containing a small amount of moisture;

The structural design of this equipment adopts a screen-less bottom discharge port. Adjusting the gap size between the two grinding rollers can ensure that the wet material can be discharged smoothly and is less likely to cause blockage. The horizontal design is mainly used for the dust-proof design of the discharge port. Configuration to reduce dust during construction and production.

Vertical impact sand making machine

Vertical sand making machine, also called vertical impact sand making machine, has an output of 40-650 tons per hour. It relies on impact energy to crush and shape materials. Especially in the construction sand making process, it can freely switch between stone-on-stone and stone-on-iron. Working mode, the stone is completely turned into sand, and the discharged material has uniform particle size and good particle shape;

In addition, compared with the old sand making machine equipment, this new type of vertical impact sand making machine adopts a deep cavity rotor and both sides + middle feeding method. The feeding amount can be increased by about 30%. The upper and lower guard plates can be turned around, which greatly improves the efficiency of the sand making machine. It improves the utilization rate, has strong wear resistance, and the whole machine has stable production and long service life.

Which one is better, rod mill sand making machine or vertical sand making machine?

It is recommended to use a vertical sand making machine! The specific reasons are as follows:

01、In terms of work losses:

Rod mill: It also needs to be shut down every year to replace the rod mill transmission pinion and reducer pinion. In the later stage, the expensive and worn supporting sliding bearings and transmission gears at both ends of the mill need to be repaired/replaced.

Vertical impact sand making machine: When processing limestone, it runs for about 2,000 hours (when processing granite, it runs for about 120-200 hours) before it is necessary to replace the impeller with 3-4 evenly arranged sandblasting machines with a single weight of 3-30 kg. The material head/up and down flow material plates can be replaced by one person in 2 hours, making operation and maintenance easy.

02、In terms of production costs:

The cost of rod mill sand making machine is 9.15 yuan/ton, and the cost of vertical impact sand making machine is 5.34 yuan/ton. Although the absolute cost has changed greatly now, the relative cost of the two has almost remained unchanged. That is, sand making from medium-hard raw materials such as granite, vertical The cost of impact sand making machine is 58.4% of the cost of rod mill sand making machine;

03、From the perspective of environmental protection:

The noise of the rod mill is less than 70 decibels, and the noise of the rod mill is more than 110 decibels. The rod mill needs to add 2-3 times more flushing water than the sand making machine.

04、In terms of price:

The price of the rod mill sand making machine is more favorable than that of the impact sand making machine. Because the output of the equipment is not high, the price is relatively cheaper; although the price of the vertical impact sand making machine is higher than that of the rod mill sand making machine, the equipment has The shaping function is more suitable for large-scale engineering, cement and other production fields.
