The straw crusher can crush combustible agricultural waste stalks such as corn stalks, straw, peanut shells, bean stalks, and firewood. This avoids the needless burning of these agricultural stalks, effectively protecting the environment and developing renewable energy. The machine is reliable, simple, and convenient to operate. It can process a wide range of raw materials, including corn stalks, straw, peanut shells, bean stalks, and firewood.
Straw Crusher Product Features, Uses, and Applications:
I. This product is reasonably designed, reliably manufactured, and features a simple structure, convenient operation, small size, small footprint, and is labor-saving and energy-saving.
II. The designed fully automatic electric heating device can randomly adjust the moisture content of the material, ensuring stable output and improving work efficiency.
III. The main parts of this product are made of wear-resistant materials and have undergone special treatment, allowing for continuous pressing production and ensuring durability.
IV. Applicable to the pressing and molding of various biomass raw materials (corn stalks, wheat stalks, cotton stalks, rice straw, rice husks, peanut shells, corn cobs, branches, leaves, sawdust, etc., as agricultural materials or woodworking waste).
Safety Tips for Using a Straw Crusher
(1) The straw crusher should be fixed to the ground, preferably with cement. If the work location is frequently changed, the crusher and motor should be installed on a base made of angle steel.
(2) After installation, carefully check whether the straw crusher is installed correctly and securely. Check whether the motor shaft and crusher shaft are parallel, and also check whether the tension of the drive belt is appropriate.
(3) Before starting the straw crusher, manually rotate the rotor to check whether the operation is flexible and normal, whether there is any collision inside the casing, whether the rotor rotation direction is correct, and whether the motor and crusher are well lubricated.
(4) Do not frequently change the pulleys of the straw crusher to prevent the speed from being too high or too low.
(5) After starting the straw crusher, allow it to idle for 2 to 3 minutes. Only begin feeding material after confirming there are no abnormalities.
(6) The straw crusher should be fed evenly. If any unusual noises, excessively high bearing or machine body temperatures, or material spraying outwards are observed, stop the machine immediately for inspection and troubleshooting.
(7) Before operating the straw crusher, personnel should carefully inspect the material to prevent metal, stones, or other hard objects from entering the crushing chamber and causing accidents.
(8) When feeding material, personnel should stand to the side of the straw crusher to avoid being injured by rebounding debris. When crushing long stalks, do not grip too tightly to prevent hands from being pulled in.
(9) Before stopping the straw crusher, stop feeding material first. After all material has been emptied from the machine, disconnect the power and stop the machine. Clean and maintain the machine after shutdown.
(10) After 300 hours of operation, the bearings of the straw crusher must be cleaned and the oil changed. When filling the bearing housing with oil, it is best to fill it to 1/3 full, **but not more than 1/2 full. For long-term shutdowns, the drive belt should be removed.
Crusher Maintenance
- If the rivet heads of the impeller are worn, they can be repaired by welding the impeller body to the hub with electric welding to restore the worn rivet heads to their original normal state.
- For rivet holes prone to fatigue cracks, a whole, unused new welding rod can be used to weld and repair the cracks. However, it should be done symmetrically with the impeller axis as the center. The remaining welding rod should be left at the crack location, and then a new welding rod should be used to repair the symmetrical rivet hole cracks. After welding, the remaining welding rod should be the same length as the remaining welding rod from the symmetrical rivet repair to ensure equal weight. If there are no cracks at the symmetrical rivet holes, welding rods should still be deposited there to offset the weight of the new weld at the cracked rivet holes. Welding using this symmetrical weight-addition method will repair the cracks.
- Perform a simple dynamic balancing test on the impeller. The method is quite simple. After supporting the impeller, gently rotate it by hand. Any unbalanced areas will stop at a certain point and oscillate from side to side. If there is an imbalance, spot weld weight to the opposite impeller to add weight and balance it, or use an angle grinder to remove the weld marks from the unbalanced impeller to achieve balance. This will repair the fan and allow it to operate normally. Note that during fan repair, do not use electric welding to randomly spot weld, leaving weld marks on the impeller, as this will affect the impeller's balance, failing to achieve the repair purpose and causing greater damage.
