The so-called zero pressure surface (or zero interface), which is the pressure interface formed by the point where the gas flow pressure in the system is zero (gauge pressure). There are two zero-facets in the loop airflow system, one in the blower, the airflow changes from negative pressure to positive pressure, and the wind pressure of the blower is fundamentally constant. Another zero interface is in the raymond mill, and the airflow changes from positive pressure to negative pressure.

The zero pressure surface is further divided into a full pressure zero pressure surface and a static pressure zero pressure surface. The so-called full-pressure zero-pressure surface is a surface composed of points where the total pressure is equal to zero; and the surface composed of points where the static pressure is equal to zero is called a static pressure zero-pressure surface.

In the loop system, there is a necessary interval between the full pressure zero pressure surface and the static pressure zero pressure surface, and the resistance in this interval is equal to the pressure difference between the full pressure zero pressure surface and the static pressure zero pressure surface. The concept of using full-pressure zero-pressure surface is for the purpose of accounting, and the concept of using static pressure zero-pressure surface is to facilitate the investigation of the situation of powder blowing (winding) or leaking (human) wind in order to control the operation.

However, in the calculation of the moving zero pressure surface, it is necessary to apply the concept of full pressure and full pressure zero pressure surface. The full-pressure zero-pressure surface and the static-pressure zero-pressure surface are always presented in pairs. If a zero-pressure surface is moved, another zero-pressure surface will follow. The resistance of the residual air duct determines the position of the full pressure zero pressure surface. When the residual air duct resistance is not large, the zero pressure surface is below the feeding port during operation, and the zero pressure surface is not required to be moved normally. During production, the flow rate of the controlled residual air duct (tempered residual air duct gate) shall be such that the full pressure zero pressure surface is constant at the suspension roller and the grinding ring (steel ring); when the air volume of the residual air duct is controlled in Table 3-4 When the number is limited, the resistance is not greater than the values ​​listed in Table 3-1, and the zero pressure surface may not be moved; when the residual air duct adopts a large dust collector, or because the dust removal requirement is high, the entire wind loop is required. In the case of the negative pressure mode, the full pressure zero pressure surface is moved from the raymond mill to the vicinity of the blower outlet, and even moved into the blower.

After the user purchases the cone crusher, in order to ensure the production life and the efficiency of the operation, the equipment is tested at intervals. So what are the testing tasks of the cone crusher?

The general inspection time is started after the equipment is finished, and it is cooled for five or six hours. The inspector firstly checks the flatness of the conical surface to see if there is any unevenness. If so, inform the technician to make the transformation. It is found that unqualified parts or parts with deviations should be replaced in time.

The counterweight of the large bevel gear of the cone crusher is to eliminate the inertial force and moment of inertia of the direction change caused by the crushing cone. Due to the limitation of the size of the crusher, the inertial force of the crushing cone cannot be completely eliminated. Therefore, when the crushing cone rotates, a large unbalanced inertial force is generated. This unbalanced inertial force is caused by the crusher frame and the basic vibration. Disturbance. That is, the disturbance of the crusher is the unbalanced inertial force generated when the crusher's crushing cone rotates around the central axis.

The cone crusher is an important ore dressing equipment with relatively large body shape. During its operation, the wear of the parts will seriously affect the vibration stability of the crusher, and at the same time, the machine will be in a state of forced vibration for a long time, which will seriously affect the crushing. The safe operation of the machine. The study found that the disturbance is an important factor affecting the forced vibration of the crusher. Let us analyze it here.

For the operation of the empty machine with a cone crusher, before starting the machine, check whether the equipment is installed well. Everything is normal before it can be turned on. During the empty operation, it is necessary to check the sealing, jamming, friction, and impact of the equipment. . During the trial rotation, check whether the cylinder body has obvious sway, whether there is too much noise, ensure that the cylinder sway does not exceed 0.5mm, and the noise is controlled within 85db. After the cone is broken and put into formal work, the staff needs to insert the special thermometer for the rolling bearing into the oil control of the bearing seat, and measure it once every hour, knowing that the temperature is stable.

We only know that the sand making machine can also be used in the sand and gravel production line to make the sand and gravel production line better. So how does the sand making machine work in the sand and gravel production line to assist the sandstone production line? We don't seem to be very clear. Today, let's take a look at how the sand making machine performs in the sandstone production line. Is it really as good as people's legends?

In the gravel production line, the bulk raw ore through silo is reasonably sent to the jaw crusher for coarse crushing by the vibrating feeder; the coarsely crushed stone is sent to the sand making machine by a belt conveyor or other conveyor for further processing. Broken, that is, finely crushed; the finely crushed stone is sent to the vibrating screen by a belt conveyor for screening, and several stones of different specifications are screened: the stone that meets the particle size requirement is sent by the finished belt conveyor to the finished material pile; The required stones are returned to the sand making machine by the belt conveyor for re-crushing, thereby forming a closed circuit multiple cycles. The finished product size can be combined and graded according to requirements. In addition, in order to protect the environment, an auxiliary dust removal device can also be provided.

Why is the sand making machine working well in the sandstone production line? This is definitely an advantage in some aspects.

The following items should be noted when installing the Jaw crusher: (1) Since the jaw crusher has a large vibration during operation, the machine should be installed on the concrete foundation to reduce vibration, noise and influence on the foundation of nearby buildings and structures. A hardwood mat, rubber band or other shock absorbing material is placed between the crusher and the concrete foundation. Therefore its installation has a lot to do with the crusher. The crusher is a kind of gravel equipment mainly composed of a feeding hopper, a distributor, a vortex breaking chamber, an impeller, a main shaft, a base, a transmission device and a bracket. During the installation, the crusher should be leveled so that its main axis is perpendicular to the horizontal plane. Appropriate space should be left above and on both sides of the crusher for hoisting and maintenance. Stone Jaw crusher crushing equipment installation and commissioning attention to problems Stone crushing equipment installation and commissioning attention. (2) The basic drainage tank shall be laid with a layer of metal plate and have sufficient inclination angle (depending on the fluidity of the material to be determined by the cement mill, not less than 50 & deg;), so as not to hinder the smooth discharge of the broken product. The location of the stone crushing equipment installation will vary depending on the location of the crushing site. When adjusting, loosen the T-row bolt and tension spring. (3) The size of the discharge opening should be adjusted according to the required product size. Thereafter, adjust the spring preload to ensure that the thrust plate is in close contact with the thrust plate pad when the machine is in operation. Use the top bolt to open the adjusting seat, insert or withdraw the gasket of the corresponding thickness, and then return the lifting bolt. Adjust the entire production line of the cement production line under the action of the weight of the moving body, and close it to the ear seat of the rack. The film sets are pressed together.

The world's vertical roller mill was developed in Germany in the 1900s. It is said that its grinding principle is similar to that of the ancient mill grinding grain. It uses the bed grinding principle to grind the material, overcomes many defects of the ball mill grinding mechanism, has high grinding efficiency, low power consumption, and drying ability. Large, allowing the grinding material to have a large particle size. Moreover, the grinding process is simple, the floor space is small, the civil construction cost is low, the noise is low, the wear is small, the service life is long, and the operation is easy. These features have made the vertical roller mill more and more attention. So, do you know the static blades of the vertical roller mill?

The role of static blades of vertical roller mills:

The high-speed motor drives the drive shaft to rotate through the transmission device, and the material enters the powder selection chamber, and then falls between the upper and lower cones and the powder passage pipe on the discharge tray. The spreading disc rotates with the vertical transmission shaft, and the material is evenly sprinkled around under the action of inertial centrifugal force. The dispersed material is connected to the fan through the air inlet. Under the action of high-speed airflow, the coarse and heavy particles in the material are subjected to the action of inertial centrifugal force and are collided toward the inner wall surface of the powder separation chamber and then slide down the wall surface, falling into the coarse powder collecting cone, and the remaining particles are rolled up by the rotating rising airflow. . When passing through the action zone of the large wind blade, under the impact of the big wind blade, a part of the coarse powder particles are thrown to the inner wall surface of the powder selection chamber, and after the collision, slide down the wall surface to the coarse powder collecting cone. After passing the large wind blade, the medium coarse powder and fine powder continue to rise through the vertical guide vane under the action of the ascending airflow, entering the secondary particle selection zone, and the strong and stable plane vortex formed by the dusty airflow makes the medium coarse powder It is thrown to the vertical guide vane under the action of centrifugal force, and then falls into the medium coarse powder collecting cone. The fine powder that meets the requirements is discharged through the medium-thick powder tube and enters the interior through the cage rotor, and enters the high-efficiency and low-resistance cyclone separator with the circulating wind, and then slides into the fine powder collecting cone to become the finished product.

It is clear that the role of product components is critical to understanding a product. This will help us to better select the products we need and let the products work for us. Although the stationary blade is a very small part, it has a very important position in the process of selecting the powder in the vertical roller mill.
