1. Feed hopper of the
shockwave machine
The structure of the feed hopper is an inverted pyramid (or cylinder), the feed inlet is provided with a wear ring, and the incoming material from the feeding equipment enters the crusher through the feed hopper.
2. Distributor of the
shockwave machine
The distributor is installed on the upper part of the vortex crushing chamber. The function of the distributor is to divert the materials from the feed hopper, so that part of the materials directly enter the impeller through the central feed pipe, and are gradually accelerated to a higher speed to be ejected, so that another part of the materials bypass into the outside of the impeller in the vortex crushing chamber from the outside of the central feed pipe, The high-speed materials ejected from the impeller are impacted and crushed, which does not increase power consumption, increase production capacity and improve crushing efficiency.
3. Vortex crushing chamber
The structural shape of the vortex crushing chamber is an annular space composed of upper and lower cylinders. The impeller rotates at high speed in the vortex crushing chamber. Materials can also reside in the vortex crushing chamber to form a material lining. The crushing process of materials occurs in the vortex crushing chamber. The material lining separates the crushing action from the vortex crushing chamber wall, so that the crushing action is limited to the materials, Play the role of wear-resistant self lining. The observation hole is used to observe the wear of the wear-resistant block at the emission port of the impeller channel and the wear of the lining plate at the top of the vortex crushing chamber. The observation hole must be tightly sealed when the crusher works. The distributor is fixed on the upper cylindrical section of the vortex crushing chamber. The impeller rotates at high speed to generate air flow, and an internal self circulation system is formed through the distributor and impeller in the vortex crushing chamber.
4. Impeller
The impeller structure is a hollow cylinder made of special materials, which is installed on the shaft head at the upper end of the main shaft assembly. The conical sleeve and key are connected to transfer the button distance and rotate at high speed. The impeller is the key component of HX vertical impact crusher. The material enters the center of the impeller through the central feed pipe of the distributor at the upper part of the impeller. The material is evenly distributed to each launching channel of the impeller by the distribution cone in the center of the impeller. At the outlet of the launching channel, a wear-resistant block made of special materials is installed, which can be replaced. The impeller accelerates the material to the speed of 60 ~ 75m / s and ejects it, impacting the material lining in the vortex crushing chamber for strong self crushing. Upper and lower flow channel plates are installed between the cone cap and the wear-resistant block to protect the impeller from wear.
5. Spindle assembly
The main shaft assembly is installed on the base to transmit the power transmitted by the motor through the V-belt and support the rotating movement of the impeller. The main shaft assembly is composed of bearing seat, main shaft, bearing, etc.
6. Base
The whirling crushing chamber, main shaft assembly, motor and transmission device are installed on the bottom seat. The structure of the base is shaped. The middle part is a quadrangular space. The center of the quadrangular space is used to install the main shaft assembly, and discharge channels are formed on both sides. The double motor is installed at both longitudinal ends of the base, and the base can be installed on the support or directly on the foundation.
7. Transmission
The belt transmission mechanism driven by single motor or double motor (above 75kW, double motor transmission) is adopted. The two motors driven by double motor are installed on both sides of the main shaft assembly respectively. The two motor pulleys are connected with the main shaft pulley by belt to balance the force on both sides of the main shaft without generating additional torque
