Single-stage crushers mainly rely on impact energy to complete the crushing of materials, so there will be a certain frequency and intensity of vibration during normal use. In order to avoid strong vibrations, they are generally installed on a concrete foundation. In order to reduce vibration and noise, A hardwood pad rubber band or other cushioning material is placed between the equipment and the concrete. Therefore, the installation must be carried out strictly in accordance with the basic drawing provided by the manufacturer. In order to allow users to carry out production operations safely and with high yield, the following is an introduction to single-stage crushing The installation procedure of the crusher.
One preparation before installation
1 Before installing the crusher, the unloading under the crusher foundation should be installed Chute
2 If the concrete foundation is installed, it is required to check the depth of the foundation hole, eliminate the debris in the hole, place anchor bolts in place, and set two wedge-shaped pads next to each foundation hole Iron
3 When installing, pay attention to the assembly number of the manufacturer, and remove the dust and protective coating on the mating or bonding surface of the parts, and eliminate the defects during transportation.
4 During installation, the joint surfaces of the parts must be coated with lubricating oil, of which the fixed surface is coated with dry oil, and the movable surface is coated with thin oil.
Installation of the second frame
By In the end wall of the silo and the base of the crusher, the horizontal lead wire is pulled as the center axis reference to prevent the deflection of the crushers positioning.First, the anchor bolts are screwed into the foot support plate and passed through the steel pipe between the foundation layers. Then wrap the bituminous hemp rope around the coarse sand into the pipe and seal it, waiting for the second grouting. The lower shell is composed of the lower shell I, the lower shell II and the tie rod. The joint surface is positioned with a positioning pin, and the bolt is tightened, and then the position is corrected on the basis. At the same time, the anchor bolt is inserted into the anchor bolt hole of the frame, and adjusted under the chassis frame through the block shim After aligning, after completing this work, in order to prevent the casing from moving during pouring, the anchor bolts must be slightly tightened, and finally the foundation is re-poured. When the concrete is solidified, the foundation bolts are tightened.
Three-safety door installation
It is required to install the safety door in a normally closed position after the suspension is balanced, and it can rotate freely by applying external force to facilitate the action of foreign objects in the machine It can be automatically opened after the foreign matter is removed. After the safety door is opened, it must not touch other parts.
Four-row grate installation
Discharge grate After being hoisted into the machine, its front and rear suspension bolts are hung at the predetermined position in the machine. After confirming that the position meets the requirements, lock the front and rear suspension bolts, the top screws at the front and the top screws on both sides of the lower shell. Make sure that it does not loosen and displace under vibration.
Five feeding roller installation
Sleeve the support ring on the main and driven roller shafts, and then fix them with keys. Before installing the shock-absorbing rubber block, carefully clean the contact surface of the support ring roller body and the rubber shock-absorbing block with water reducer to eliminate any oil stains and ensure The friction applied between rubber and metal materials.
