The roller sand making machine produces uniform sand, the equipment is durable, and the production cost is low. When the demand for sand and gravel is tight, it is a very popular sand making equipment to build a sand and gravel plant. The output of the roller sand making machine can be adjusted between 2-10mm, but how to adjust the size of the discharge opening? How much does a roller sand making machine cost? The following article will introduce it to you in detail.
How to adjust the size of the discharge port of the roller sand making machine
1. Change the position of the bolt: Changing the position of the bolt can increase the discharging granularity, shorten the distance between the two rollers, and reduce the discharging granularity. It is recommended to change the bolt position according to the actual situation to quickly produce materials of corresponding sizes.
2. Change the number of gaskets: The gaskets are located between the frame and the movable bearing. By placing gaskets of different thicknesses between the frame and the movable bearing, the width of the discharge opening between the two rollers can be adjusted by changing the number of gaskets. Meet the requirements of different product particle sizes. Adjust the number of gaskets according to the actual situation to ensure that the discharge particle size meets the needs.
In fact, this discharge opening size adjustment device also takes into account overload protection (safety device). When the double-roller sand making machine encounters unbreakable hard materials or metal entering the crushing chamber, the spring is compressed, the moving roller retreats, and the discharge opening increases. After unloading, under the pressure of the spring, the movable roller resets and the iron parts pass smoothly. , without causing irreparable damage to the machine itself.
Advantages of roller sand making machine
Small footprint, large crushing capacity, uniform discharge particle size, and low over-crushing rate;
Simple structure, low noise, easy maintenance, sensitive overload protection, safe and reliable;
Simplify the process and reduce investment and production costs;
How much does a roller sand making machine cost?
The roller sand making machines sold on the market have different prices depending on the model and production capacity. According to Zhengzhou Global Heavy Machinery, the price of a small roller sand making machine is around 10,000-50,000 yuan, the price of a medium-sized roller sand making machine is around 50,000-100,000 yuan, and the price of a large-scale roller sand making machine is between 100,000-350,000 yuan. between. Different roller sand making machines have different models, different production capacities, and different abilities to create profits for customers. It is normal for prices to be high or low. In addition, each manufacturer's production process and manufacturing technology will affect the production cost of the machine itself, which is also the reason why different manufacturers quote different prices.

The double-roller sand making machine can crush materials with compressive strength ≤160MPa. It is suitable for coarse and medium crushing of brittle block materials in cement, chemical industry, electric power, mining, metallurgy, building materials, refractory materials, coal mines and other industries. The granularity is adjustable. It is particularly easy to use in the coal industry. Raw coal can be directly crushed as long as iron and impurities are removed, without removing gangue. The crushed materials have uniform particle size and low crushing rate, which simplifies the coal preparation process and reduces investment and output. cost.
