Introduction
It's the name of the coal-rod forming machine: Coal rod machine, coal-rod machine, hollow coal rod machine is the principle of screw extrusion, which will be modulated by the coal powder with certain strength.

Working Principle
The rotation of the impeller from the feeding port with coal, coal and coal will move forward, gradually compressed, and produce particles, close together, stirring and mixing is relatively large. At this time, the coal particles, particles and the blade and the cylinder produce strong friction and shear, and at the same time in the role of heat, the coal temperature rise, water and binder more uniform, the plastic is also greatly increased, and then through the control of mold cone shape, coal grain compression between the more closely, and then press into the flat parts of the mold, out of coal rod machine and molding.
Coal rod machine adopts Hardened reducer, small volume, and high bearing capacity. Coal rod extrusion machine inside the impeller adopts thickening blade design, impeller and cylinder body is lined with wear resistant casting material and, life than ordinary steel improve 4-5 times. The head of the coal rod machine export with replaceable wear resistant alloy steel production, the replacement is convenient. Head and cylinder in the form of hinge, maintenance can be opened; replacement within the impeller and cylinder liner is very convenient.

Installation and Commissioning
1. 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.
2. 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
1.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.
3.Feed the blockage, using wood or bamboo dredge, avoid the use of metal bar.
4.The machine rotating part of the bearing should be regularly injected into the lubricating oil; bearing part of the temperature is not more than 60 degrees.
5.Stop before the end of the material, the cylinder in the air after the extrusion of material, the demolition of the machine head, after washing, to prepare for work.

6.In order to make the motor not exceed the load operation, it is recommended that the user to install the current voltage meter, according to the current meter to adjust the amount of material and water content.
