Sand making machine is an essential sand making equipment in the sand and gravel industry. A sand making machine is analyzed based on the structure from top to bottom and from inside to outside. It is mainly composed of eight parts: hopper, distributor, eddy current crushing chamber, impeller, spindle assembly, base, transmission device and lubrication system. The following is a detailed introduction to these eight important components. 1. Feed hopper

The feed structure of the sand making machine is in the form of an inverted frustum, and a wear-resistant ring is set at the feed port. Materials enter the interior of the sand making machine through the feed hopper. 2. Distributor

The distributor is installed on the upper part of the eddy current crushing cavity of the sand making machine. The distributor is used to directly enter the impeller through the central feed pipe and gradually accelerate to a higher speed to be thrown out without Increase power consumption, increase production capacity and improve crushing efficiency. 3. Eddy current crushing chamber

The eddy current crushing chamber of the sand making machine is an annular space composed of upper and lower cylinders. The material can reside in the eddy current crushing chamber to form a material lining. The material is The crushing work is carried out in the eddy current crushing chamber. The crushing layer and the crushing cavity wall are separated by a material lining, so the crushing effect is limited to the material and acts as a self-lining. 4. Impeller

The impeller structure of the sand making machine is a hollow cylinder made of special materials. It is installed at the end of the main shaft assembly and performs high-speed rotation in the vortex chamber. The torque is transmitted by a tapered sleeve and a key link. The high-speed rotating impeller is a key component of the sand making machine. The material enters the center of the impeller from the central feed tube of the feeder part on the intermediate wheel, and the material is evenly distributed to each discharge channel of the impeller through the distribution cone in the center of the impeller. 5. Spindle assembly

The spindle assembly is installed on the base of the sand making machine, and the V-belt transmits the power provided by the motor to support rotation. The main shaft assembly of the sand making machine mainly consists of the main shaft, bearings and bearing seats. 6. Base

The base is a structure used to make parts. For example, the motor, eddy current crushing chamber, spindle assembly, and transmission device are all installed on the base. 7. Transmission device

The transmission device is a belt transmission mechanism driven by dual motors. The two motors are installed on both sides of the spindle assembly and connected with the spindle belt to balance the forces on both sides of the spindle. Produce extra torque. 8. Lubrication system

The lubrication system of the sand making machine adopts Mobil Auto Lubrication Super Centralized Lubrication or 3# lithium-based grease. In order to facilitate lubrication, the oil pipe is led to the outside of the machine so that the oil pump can be filled with oil regularly.
