With the continuous development of national infrastructure construction and the depletion of natural sand resources, old-fashioned sand making machinery can no longer keep up with production needs. The market urgently needs a new type of sand making machine to meet the increasingly tight supply of sand and gravel materials. In this context, our company's research personnel have studied for many years, referring to the working principles of fine crushers at home and abroad, and based on feedback from users, combined with their advantages, designed a new type of limestone sand making machine (sanding machine).

Limestone sand making machine

The new generation of limestone sand making machine has been successfully developed by integrating the strengths of hammer crushers and impact crushers, due to its unique crushing process. Most other types of sand making machines use metal components to break rocks, while limestone sand making machines use the rocks thrown into the crusher to collide with each other and self break. Its performance plays an irreplaceable role in various ore crushing equipment and is currently an effective, practical, and reliable crushing machine. Limestone sand making machines are widely used in various industries such as ores, cement, refractory materials, bauxite clinker, diamond sand, glass raw materials, machine-made construction sand, stone materials, and various metallurgical slag.

Advantages of limestone sand making machine products

This equipment has a high crushing ratio and output, which is 1.4 times higher than similar products in China. It has the ability to crush hard materials such as shale, glass, ceramics, river pebbles, granite, basalt, iron ore, bluestone, and metal ores, especially in the crushing application of machine-made sand and gravel and metal ores. The vulnerable parts are made of high hardness, high toughness, and multi-element alloy wear-resistant materials, which increase the service life by 2-3 times; The gap between the hammer head and the counterattack plate can be adjusted to meet the crushing requirements of various materials.

1. The heavy-duty vertical sand making machine has a high crushing ratio and no screening strip, making it less prone to clogging when crushing materials with high moisture and mud content.

2. The bearings are arranged horizontally, have a long service life, and can crush materials with high temperatures (such as cement clinker).

3. Adopting an elastic adjustment mechanism, unbreakable materials can be automatically discharged without causing equipment damage.

4. The rotor structure of this machine is unique, and it hardly wears out when crushing materials. And the rear chamber is equipped with a screw or hydraulic opening mechanism, making it easy to replace vulnerable parts without starting the main equipment.

Working principle of limestone sand making machine

When the sand making machine is working, the rotor rotates at high speed under the drive of the electric motor, and the material enters the crushing chamber and collides with the plate hammer of the rotor for crushing, and then enters the second crushing chamber for crushing. During the crushing process, not only is there an impact crushing between the material and the plate hammer and lining plate, but also the stone shaping between each plate hammer and the crushing chamber is completed, and then discharged from the discharge port.
