Performance characteristics

1. Higher yield

Increasing the passing capacity of the rotor increases the material density in the crushing chamber, resulting in higher crushing efficiency and improved product shape.

2. More cost saving

Developing deep cavity rotor technology, extending the service life of wear parts and installing throwing heads, greatly reducing downtime caused by replacing wear parts.

3. Reduce energy consumption

Reduce motor power, save energy, reduce the operating cost of wear parts by 50% per ton of product, and improve the efficiency of crusher operation with less maintenance time.

4. Professional crushing of hard rock

This sand making machine can crush various materials, especially hard and highly abrasive rocks.

5. Using techniques of stone to stone and stone to iron

It can produce various product gradations such as 0-5mm for fine-grained products, and has the functions of crushing and grinding. It can process all hard, highly abrasive, and brittle materials.

6. The bearings adopt high-precision international brands to ensure a low failure rate of the system.

7. Equipped with German original thin oil lubrication station to solve the heating problem of bearings in old models.

8. Equipped with a hydraulic opening device, the internal maintenance and replacement of the crushing chamber are convenient and fast.

Working principle

The sand making machine is mainly composed of an electric motor, an impulse device, a main shaft, an impeller, a feeding hopper, a powder feeder, a crushing chamber, a base, a lubrication device, and other parts. The following is an introduction to the structure of the sand making machine:

1. Feed hopper: The feed hopper is the inlet for materials to enter the crushing chamber.

2. Distributor: The material entering the crushing chamber is divided into two parts by the distributor, with one part entering the high-speed rotating impeller through the gaps of the distributor.

3. Impeller: The material is rapidly accelerated inside the impeller and ejected from the flow channel of the impeller at a speed of 60-70 meters/second, colliding with other materials to break them, and then impacting the material lining layer inside the vortex support chamber together.
