What is the working principle of the extruder?

The use of "continuous extrusion machine pressure shift principle, hydraulic pump of diesel engine mechanical energy into hydraulic energy, all the way through the low speed high torque hydraulic motor driven screw rotation, will enter the mixing concrete mix Long Wharf transported to another road forming cavity; driven by hydraulic motor vibrator, the mixing the molding material in the cavity to generate high-frequency vibration. The molding cavity mixes the comprehensive influence of the screw extrusion pressure and vibration force, full of molding cavity, and achieve the compactness of the set, the auger axial thrust under the action of side wall extrusion machine with dense concrete support for moving forward after continuous formation of trapezium shape of concrete side wall.

Mix evenly into the auger chamber, side wall extrusion machine has uniform forward, uniform form set the compactness of concrete side wall; mixture into the intermittent bin, squeezing machine forward speed is variable; when the mixture stop supply, squeezing machine forward speed is zero. That is, the advancing speed of the edge wall extruder is uncontrolled automatic regulation, and the precondition of the adjustment is the compactness of the molding compound.

The density of the concrete side walls can be set as required. The premise condition of moving sidewall crushing machine is a molding cavity compacting mixture force equal to the machine forward and all kinds of resistance, by adjusting the molding chamber number and the front wheel support height weight can change the friction resistance between the molding cavity mixture and template, friction is the main component of the total drag on the total. To reduce resistance and compactness of mixture decreases; on the other hand, dense degree of mixture increase.

The basic structure of 2. side wall extruder

The structure of the edge wall extruder consists of six parts, the rear wheel, the molding silo, the agitate storehouse, the power storehouse, the hydraulic system and the front wheel and the steering mechanism. The three sections of the forming bin, the mixing bin and the power bin are connected by bolts, and each side of the forming cavity has a rear wheel. The front wheel and the steering mechanism are welded at the front end of the power storage bin, and the hydraulic system is in the power storage bin.
