SC Series Impact Crusher

The SC series impact crusher adopts the inter particle crushing principle. During the natural falling process, the materials collide with the materials accelerated by the impeller under the action of high-speed centrifugal force, resulting in high-speed impact and high-density pulverization. And it forms multiple blows, rubs, smashes, and then directly discharges from the lower part.

Vertical Impact Crusher Structural Features

Structural Features of Vertical Impact Crusher Here we introduce the structural characteristics of the vertical impact crusher. It consists of the motor, transmission, spindle assembly, impeller, feed hopper, distributor, vortex breaking chamber, base, The lubricating device is composed of several parts. In order to facilitate reading, his structure is divided into small sections to introduce:

(1) Transmission device (including motor) adopts double-motor or single-motor drive belt transmission mechanism. Two motors driven by two motors are respectively installed on both sides of the main shaft assembly. The two motor belt pulleys are connected with the main shaft pulley to make the main shaft. The sides are balanced and no additional torque is generated. The single-motor drive spindle is subjected to a single-side force to generate additional torque. When the motor power is above 55 kW (single motor power), it is recommended to use a dual-motor drive.

(2) Spindle assembly: The spindle assembly is mounted on the base to transmit the power transmitted by the V-belt from the motor and to support the rotary motion of the impeller. The spindle assembly is composed of a bearing housing, a main shaft, a bearing, and the like.

(3) Impeller: The impeller structure is a hollow cylinder, which is mounted on the upper end of the main shaft assembly. The conical sleeve and the key joint are used to transmit torque and rotate at high speed. The impeller is a key component of the PL vertical impact crusher. The mineral raw material enters the center of the impeller from the central feed pipe of the upper part of the impeller. The material is evenly distributed from the cloth cone in the center of the impeller to the respective emission streams of the impeller, and the exit of the launching channel is installed, and the wear-resistant block made of special material is installed. The wear block can be replaced after being worn, and the impeller accelerates the material to 70~ The speed of 100 m / s is thrown out, impacting the ore bed in the vortex breaking chamber, and undergoing strong self-pulverization.

(4) Feeding hopper: The structure of the feeding hopper is an inverted prismatic body, and the feeding port is provided with a wear ring, and the incoming material from the feeding device enters the crushing machine through the feeding hopper.

(5) Dispenser: The distributor is installed in the upper part of the vortex crushing chamber, and its function is to divert the material from the feeding hopper, so that a part of the material is directly accelerated into the impeller by the central feeding tube and is gradually accelerated to a higher speed to be ejected. The material is bypassed into the outer side of the impeller in the vortex crushing chamber from the outside of the central pipe, and is impacted and broken by the high-speed material ejected from the impeller, without increasing the kinetic energy consumption, increasing the production capacity and improving the crushing effect.

(6) Vortex breaking chamber: The structure of the vortex breaking chamber is an annular space composed of upper and lower cylinders, and two holes are opened in the upper and lower cover plates of the lower cylinder, the upper part is connected with the cylinder body, and the lower part is connected with the discharging port. The impeller rotates at high speed in the vortex breaking chamber, and the material in the vortex breaking chamber can also reside in the material bed layer. The crushing process of the material occurs in the vortex breaking chamber, and the crushing action and the eddy crushing chamber are formed by the ore bed. The walls are separated so that the crushing effect is limited to between the materials and acts as a wear-resistant self-lining. An observation hole is arranged on the upper cylinder cover plate to observe the wear condition of the wear block at the launching port of the impeller flow passage and the wear condition of the top lining plate of the vortex crushing chamber, and the observation hole must be tightly sealed when the crusher works. The distributor is fixed to the upper cylindrical section of the vortex breaking chamber. The airflow generated by the high-speed rotation of the impeller forms an internal airflow self-circulation system through the distributor and the impeller in the vortex crushing chamber.

(7) Base: the vortex breaking chamber, the spindle assembly, the motor and the transmission are all mounted on the base, and the middle of the base is a quadrangular space for mounting the spindle assembly and forming a discharge channel on both sides of the quadrangular space. . The dual motors are mounted on the longitudinal ends of the base, and the base can be mounted on the bracket or directly on the foundation.

(8) Bracket: According to the different working places of the crusher---open-air operation or indoor operation, the user can consider configuring the bracket or not configuring the bracket.

(9) Lubrication system: It is lubricated with molybdenum disulfide dry oil. The lubrication part is the upper bearing and the lower bearing of the main shaft assembly. In order to facilitate oil filling, the machine uses the oil pipe to lead the oil cup to the outside of the machine, and regularly refuels with a dry oil pump. A general understanding of the factors affecting the production capacity of the impact crusher. Generally speaking, there are many factors affecting the production capacity of the impact crusher. Generally speaking, there are five factors. I will describe the five factors and propose corresponding solutions.

1. Hardness of the material: The harder the material is, the more difficult it is to sand, and the more severe the wear on the equipment. Sand production is slow and low in ability. Therefore, we need to pay attention to the selection of materials.

2. The fineness of the material after crushing of the impact crusher: the fineness requirement is high, that is, the finer the material required to make the sand, the smaller the sand making ability. In this regard, specific requirements are required. If there is no special requirement, the fineness of the material is generally set to medium and fine.

Scope of application

1. Artificial sand making of river pebble, rock (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, and stone chips.

2. Production of aggregates, road fabrics, cushioning materials, asphalt concrete and cement concrete aggregates.

3. In the engineering field, water conservancy and hydropower, high-grade highways, highways, high-speed railways, passenger dedicated lines, bridges, airport runways, municipal works, high-rise buildings, sand production and stone shaping.

4. In the mining field, the fine crushing process in the front stage of grinding, materials in the building materials, metallurgy, chemical, mining, refractory materials, cement, abrasives and other industries are broken.

5. High abrasiveness and secondary disintegration and crushing, environmental protection projects such as sulfur removal, steel slag and construction waste crushing in thermal power and metallurgical industries.

6. Production of glass, quartz sand and other high purity materials.

Folding factors affecting production capacity

Generally speaking, there are many factors affecting the production capacity of the impact crusher. Generally speaking, there are five factors. I will describe the five factors and propose corresponding solutions.

1. Hardness of the material: The harder the material is, the more difficult it is to make sand, and the more severe the wear on the impact crusher. Sand production is slow and low in ability. Therefore, we need to pay attention to the selection of materials.

2. Composition of the material: The more fine powder contained in the material before the impact crusher, the more the sand is affected, because these fine powders tend to adhere and affect the transportation. Therefore, materials with a high content of fine powder should be sieved once in advance. The fine powder should be filtered out of the material as much as possible so as not to affect the normal operation of the impact crusher.

3. The fineness of the material after crushing of the impact crusher: the fineness requirement is high, that is, the finer the material required to make the sand, the smaller the sand making ability. In this regard, specific requirements are required. If there is no special requirement, the fineness of the material is generally set to medium and fine.

4. The viscosity of the material: that is, the greater the viscosity of the material, the easier it is to adhere. The material with high viscosity will adhere to the inner wall of the sand making chamber in the impact crusher. If it cannot be cleaned in time, it will affect the working efficiency of the impact crusher. In severe cases, it may affect the normal operation of the vertical crusher. Therefore, when selecting materials, it must be noted that the viscosity of the materials is not too large.

5. Humidity of material: When the moisture contained in the material is large, the material is easy to adhere in the vertical crusher, and it is easy to cause blockage during the feeding process, resulting in a reduced sand making capacity. To solve this problem, we must first strictly control the humidity of the material when selecting materials. If the humidity of the selected material is too large, we can use sunshine or air drying to reduce the percentage of moisture in the material.
