Rods forming machine
Coal rod shaping machine alias: coal rods machine, coal rods extrusion machine, coal rods extrusion machine, hollow coal rods machine is using a screw extrusion principle, modulated the coal powder compressed into coal rods have a certain strength of a predetermined shape molding equipment.
- Working principle:
Rotation of the impeller from the feed inlet sandwiched between coal and coal to move forward, and coal is gradually compressed, particles are close together, and produced relatively large stirred and mixed. At this time between coal particles, particles and the blade and simplified produce strong friction and shear, also in generating heat, temperature rise of coal, water and binder is more uniform, the plasticity of coal to increase, again after the mold cone control action, between coal particles compressed more closely, then pressed into the straight parts of the mold, a coal rod machine and molding. Coal rods machine adopts Hardened reducer, small volume, and high bearing capacity. Coal rod extrusion machine inside the impeller adopts thickening blade design, impeller and cylinder liner wear-resistant casting material and, life than ordinary steel increased 4-5 times; rod machine head coal export using replaceable wear resistant alloy steel production and easy to change. The machine head and the cylinder body are hinged in form, and the repair can be opened, and the inner impeller and the cylinder lining are convenient to be replaced. - Installation and commissioning:
- Before the installation of spare parts must be thoroughly cleaned, removal of transport or storage for a long time to appear rust, and check parts is not damaged.
- According to the basic map on the basis of concrete pouring, and concrete screw, after the solidification of the coal rod machine dipping in concrete based on screw alignment, two concrete grouting, anchor bolts to be solidified, correct the machine level, the machine can be stable test machine. Before the test machine will be the lubrication of lubrication, oil content is moderate. Check all the bolts if there is a loose phenomenon, and tighten. Point to move the machine to see if there is a foreign body or abnormal sound. All confirmed that no party can start running. And check the power direction is correct. The machine idle for 3~5 minutes, then all the normal feeding trial, new machine feeding should be uniform, moderate (wet and dry water generally contain 12%~15%).
- Use and maintenance:
- Every shift before starting to check whether the rotation is flexible, there is no abnormal sound, empty machine running 2~3 minutes to feed production.
2.Raw materials must be processed, the maximum particle size of less than 3mm, adding water, adding binder, curing agent, can be used by mixing retting after 24 hours. - Feed the blockage, using wood or bamboo dredge, avoids the use of metal bar.
