With the increase in the demand for stone and the improvement of grade requirements in the industrial field, the development of the gravel area has been accelerated. In order to reduce the processing cost of gravel, many processing plants have started to process the materials with the Stone crushing plant because the total operating cost Lower, more for the enterprise to bring good returns, then the Stone crushing plant equipment which? How is the Stone crushing plant designed? For those users are most concerned about these issues, GM machine Xiaobian will do for everyone to do the following.
Stone crushing plant, also known as Stone crushing plant, is the production of construction, roads, railways and other industries with sand and stone dedicated production line. Stone crushing plant, including jaw crusher, stone crusher, impact crusher, impact crusher, vibration feeder, vibrating screen, sand washing machine, belt conveyor and so on. Our equipment has a reliable performance, reasonable design, easy operation, high efficiency and so on.
The process of Stone crushing plant is roughly: (silo) ---- feeder _ jaw crusher ---- counterattack crusher ---- vibrating screen ---- (can be finished) The The middle of the machine can be connected with the conveyor.
First, the basic process of Stone crushing plant
First, the stone material from the feeder evenly into the coarse crusher for initial crushing, and then, the resulting coarse material from the conveyor belt conveyor to the impact crusher for further crushing, crushing the stone into the vibrating screen sieve different Specifications of the stone, do not meet the requirements of the size of the stone back to the material into the impact crusher again broken. Large stone from the silo by the vibrating feeder evenly into the jaw crusher for coarse crushing, shredded stone from the tape conveyor sent to the impact crusher for further crushing; crushed stone by the tape conveyor Sent to the vibrating screen for screening, screening out several different specifications of the stone, to meet the requirements of the size of the stone from the finished product conveyor belt sent to the finished material pile; do not meet the requirements of the size of the stone from the tape conveyor back to the counterattack Crusher to break again, forming a closed loop many times. Finished particle size can be combined and graded according to the needs of users, in order to protect the environment, can be equipped with auxiliary dust removal equipment.
Second, the performance of Stone crushing plant
Stone crushing plant of high degree of automation, adjustable size of the nesting, broken rate, energy saving, production, the production of gravel uniform size, good grain shape, suitable for highway bridges and other large and medium-sized construction projects. Low operating costs, high yield, high yield, finished grain size uniform, grain shape is good, in line with national high-speed materials requirements.
The main equipment includes jaw crusher, impact crusher, circular vibrating screen and tape conveyor. The following is a brief description of the use of these equipment.
Crushed stone production line has been roughly crushed, crushed, sieved these processes, the specific process: large pieces of stone by the vibration feeder was evenly sent to the jaw crusher for primary crushing, and then by the conveyor Into the counter-crusher was broken again processing, crushed particles were sent to the circular vibrating screen was sieved grading, qualified materials were sent directly to the finished material pile to be packaged, unqualified materials were sent back to The counter-crusher continues to break, so it is recycled until all the grain sizes meet the requirements.
Analysis and Treatment of Deviation of Belt Conveyor
Belt Conveyor Belt Deviation Treatment Belt Conveyor Running Belt deviation is the most common fault. In order to solve this type of fault focus should pay attention to the installation of the dimensional accuracy and daily maintenance. There are a variety of reasons for deviation, according to different reasons to deal with differences.
1 Adjusting the load carrier group: The belt of the belt conveyor can be adjusted to the position of the roller group when the middle of the belt conveyor is in the middle; the mounting holes on both sides of the idler group are machined into long holes Adjustment. The specific method is the side of the belt which side, the side of the roller group toward the belt forward direction forward, or the other side after the move. The belt is moved in the upward direction and the lower part of the roller group should move to the left and the upper position of the roller group is moved to the right.
2 installation of aligning roller group: aligning roller group has a variety of types such as the middle of the shaft, four-link, vertical roller, etc., the principle is to use the block or roller in the horizontal direction of rotation or stop lateral thrust So that the belt automatically to the heart to adjust the belt deviation of the purpose. It is generally reasonable to use this method when the total length of the belt conveyor is shorter or when the belt conveyor is bi-directionally operating because the shorter belt conveyor is more prone to deviation and is not easy to adjust. The long belt conveyor is best not to use this method, because the use of aligning roller group will have a certain impact on the life of the belt.
3 to adjust the drive roller and reorient roller position: drive roller and adjust the drum adjustment is an important part of the belt deviation adjustment. Because a belt conveyor has at least two to five drums, all the drums must be mounted at a position perpendicular to the centerline of the belt conveyor. If the skew is too large, the deviation will occur. The adjustment method is similar to adjusting the roller group. For the head roller, such as the belt to the right side of the drum deviation, the right side of the bearing seat should move forward, the belt to the left side of the roller deviation, the left side of the bearing should move forward, the corresponding can also Move the left side bearing seat back or the right side bearing seat backwards. The tail roller is adjusted in the opposite direction to the head roller. After repeated adjustments until the belt transferred to the ideal location. It is advisable to install the position correctly before adjusting or reversing the drum.
4 tight adjustment: belt tension adjustment is a belt conveyor deviation adjustment of a very important part. The two rewinding rollers in the upper part of the hammer tension should be perpendicular to the gravitational perpendicular to the longitudinal direction of the belt, ie to ensure that the centerline of the shaft is horizontal. When tension is applied with a screw tension or a hydraulic cylinder, the two bearing housings of the tension roller should be translated at the same time to ensure that the roller axis is perpendicular to the longitudinal direction of the belt. The adjustment of the specific belt deviation is similar to that of the roller.
5 The impact of the blanking position on the belt deviation: the material at the transfer point of the blanking position on the belt deviation has a very big impact, especially in the two belt machine in the horizontal projection of the vertical impact even greater. Usually should consider the transfer point at the upper and lower two belt machine relative height. The lower the relative height, the greater the horizontal velocity component of the material, the greater the lateral impact on the lower belt, and the material is also difficult to center. So that the material in the belt cross section on the skew, eventually leading to deviation of the belt. If the material to the right side, then the belt to the left side deviation, and vice versa. In the design process should be as much as possible to increase the relative height of the two belt machine. In the space-limited movement of bulk transport machinery up and down the funnel, guide trough and other parts of the form and size should be carefully considered. The width of the general guide groove should be about two thirds of the width of the belt. To reduce or avoid the belt deviation can increase the block material to block the material, change the direction and location of the material falling.
6 two-way operation Belt conveyor deviation adjustment: two-way operation of the belt conveyor belt deviation adjustment than the one-way belt conveyor deviation adjustment is relatively difficult, in the specific adjustment should first adjust a direction, and then adjust the other one direction. Adjust the time to carefully observe the belt movement and the trend of deviation, one by one to adjust. The focus should be on the drive roller and adjust the adjustment to the drum, followed by the adjustment of the roller and the material blanking point adjustment.
