Sand should be installed in the machine can withstand four times the weight of the base on concrete or steel, but also according Sand different venues where the plant is in operation or work in the open air, the installation should be adjusted to the horizontal axis Sand vertical. When installing Sand, top of the machine should be lifting equipment Impact Sand, should also consider whether the overall machine weight lifting equipment capable, should be left at the top of the sand when lifting space should be left at the side of the overhaul of the required space. Before installing the machine to view the packing list, the number of parts to see the feature is complete and detrimental during transport. Structure composed of sand from the hopper editor, sub-feeder, whirl crushing chamber of seven parts, impeller body, spindle assembly, the base, gearing and motors and other components. Feed hopper feed hopper structure is a inverted bevel (or cylinder), the inlet wear rings set up, feeding equipment from incoming through a hopper into the crusher. Sub-feeder sub-feeder mounted whirl crushing chamber upper sand, sub-feeder from hopper role is to triage incoming new Sand, a portion of the material directly from a central feeding tube impeller is gradually accelerate to a higher speed projectile out, so the other part of the material from the outside of the center of the feeding tube, the bypass into the outer whirl crushing cavity of the impeller, be broken out from the impeller speed projectile material impact, no increase in power consumption, increase large-scale production capacity, improve crushing efficiency. Eddy crushing chamber whirl crushing chamber structure shape, the annular space formed under the two cylinders, eddy broken impeller cavity high-speed rotation, whirl crushing cavity can reside materials, forming materials lining, material crushing process takes place in eddy crushing cavity, the lining material crushing action will whirl crushing cavity wall separated, so crushing effect between the materials is limited to counterattack Sand, played the role of wear from the lining. Observation hole is to observe emission impeller wear and eddy mouth wearable pieces moving crushing chamber liner wear of the top, seal the hole must be observed shutting Crusher work. Sub-feeder fixed in the upper cylindrical section whirl crushing chamber. High-speed rotation of the impeller airflow whirl crushing cavity through the feeder, impeller is internal self-loop system. Sand motor 1. Start the pump motor to make it work for 2-3 minutes. Oil pressure gauge reading should be 0.14MPa or more. It can be read out immediately after starting the scale completely. Under normal hydraulic bearing is usually between 0.14MPa to 0.8MPa, but sometimes exceeded. 2. Sand started active force power. 3. Sand feed. Do not give into the beyond "Sand Specifications" chapter in the prescribed feeding size and processing power. 4. At startup and periodic inspections Sand vibration during equipment operation.
