Move larger power mode vibration molding machine
About block molding machine vibration frequency issues, from concrete vibration technology perspective, strong Forced vibration frequency as close to the concrete mixture particles is generated when the natural frequency Resonance, then reduce the minimum amplitude of up to max. Block Concrete mixer
Aggregate particle size of 3-10mm desired vibration frequency of 100-125Hz, but for a block Machines are not up to it, the United States is generally 46-47 Hz European high individual molding machine Up to 66-67 Hz. Which could be a vibrating system life, the vibration is too high, bearing And other short life, vibration frequency of some significance in theory, but in actual project
Point of view, especially for larger power mode vibration machine vibration is of little significance Because the actual vibration molding time is only 1-2 seconds, in such a short period of time to mix concrete block making machine ifferent vibration frequencies applied, compacting effect will not change significantly Technology.
Block making machine precision molds running
Pneumatic drive from the PC program Dynamic and manual control cutting, molding, exporting complete a row, safe and stable,Easy to maintain. Every 25 seconds a standard brick 26, the hourly production 3744; every 25 seconds out Brick 12, the hourly production 1728; every 25 seconds a standard block 4, each small
Can produce 576. Bolted Type Cement Silo of precision manufacturing, use of anti-fatigue design, extending the Life of the host. Strong exciting force, under the conditions of the general strength can be compared with the Up to 2.5 ~ 15MPa. Dual-oriented approach and with excellent long guide sleeve, Ensures precise pressure head and die operation, base and key parts of the whole cast,
Frame made of thick steel and special welding super-technology manufacturing. Regulations adopted or die becomes Grid, using time-saving machinery, reasonable design. Compact, safe and reliable,concrete batching plant a set of transmission, complete a variety of process action to simplify the mechanical structure
Build, easy to maintain. Well-made, product quality error is less than 1%, the intensity error 0.5%. Upper and lower pressure, strong vibration, particularly suitable for the production of high strength block, into You can type stacking (3-5 layers).
Concrete hollow block
The machine uses four guide posts, channel rack so that the device is more rugged, Asphalt Mixing Plant pressure head with more accurate positioning, the use of bottom die directional vertical directional vibration and upper mold plus
Pressure vibration, greatly improving production efficiency, and the production of blocks of uniform density, strong High.
Block molding machine has a wide range of materials for ability, not only for the production of concrete Soil hollow blocks, also suitable for use sand, stone, fly ash, slag, tailings, Coal gangue, perlite, ceramic and other industrial waste processed into a variety of new wall materials Material. Such as hollow cement block, sterile hole brick, standard brick.concrete mixing machine. Mobile Hollow block making machine that the product can be sand, stone, fly ash, cinder, coal
Waste rock, tailings, ceramic, perlite and other industrial waste processed into a variety of new wall Material. Such as hollow cement block, blind hole brick, standard brick, etc., without sintering.

Conveyor conveying capacity
1, the transmission capacity: conveyor conveying capacity refers to the unit of time the amount of material transported. Wheel Loader bulk materials, transportation of materials per hour mass or volume calculations; during transportation into items, the number of pieces per hour transport calculations.
2, delivery speed: increase transmission speed can increase transmission capacity. In order to make the traction belt conveyor length pieces and large, the conveying speed increasing day by day. But high-speed operation of the belt should pay attention to vibration, noise, and start braking and other issues. For chains as traction element conveyor, steel cement silo should not be too large to prevent increased dynamic loads. Simultaneous process operation conveyors, conveyor speed production process requirements should be determined.
3, scantlings: Conveyor belt width dimensions include components, slat width, hopper volume, pipe diameter and vessel size. These have a direct impact scantlings conveyor conveying capacity.
4, the transmission length and angle: transfer line length and inclination of the conveyor directly affect the size of the total resistance and the power required.
Conveyor can be horizontal, inclined and vertical transmission
Conveyor can be horizontal, inclined and vertical conveyor can also be composed space transmission lines, transmission lines are generally fixed. Asphalt Mixing Plant long distance, but also in the transportation process while completing a number of process operations, so widely used.
Design parameters are mainly two categories, one for the design of constant, which is based on the objective laws, cement mixing machine s determined by the known data or parameters given in advance. Another type of design variables, it is designed for the changing needs can be determined by structural parameters.
Screw conveyor is a continuous material handling machinery
In attempts to prevent the discharge opening of a valve cover plate. Blockage occurs because the accumulation of materials, open the top attempts to prevent the door limit switch through the same intercept power. Minimize the transverse dimension of the intermediate hanger bearings to reduce the material through the intermediate Concrete mixing plant when possible. Reasonable choice of the technical parameters, such as slow speed can not be too large. Strict implementation of control procedures, so that no load starting, empty parking; ensure continuous average feed.
Screw conveyor is a continuous material handling machinery, due to the continuous conveyor working principle, structural features, the direction of transport of materials and methods and a range of other characteristics are different, so variety. In the concrete batching plant is mainly based on the nature of transportation of materials, transport capacity, transmission distance, transmission angle, screw conveyor speed to determine the productivity and power.
Conveyor Performs necessary cleanup materials
Clogging many reasons, mainly to prevent clogging may take the following measures:
Entering the conveyor materials for the necessary cleanup, to prevent large complex or fibrous impurities into the machine causing blockage. Install hopper and clogging material level sensor, concrete block making machine and alarm. Increase the spout or lengthen trough ends to address poor or too late nesting nesting problem. Cement silo, also in the material outlet chute ends a short anti-rotation vanes mounted to prevent blocking material ends.

Blockage occurs because the accumulation of materials, open the top attempts to prevent the door limit switch through the same intercept power. Minimize the transverse dimension of the intermediate hanger bearings to reduce the material through the intermediate bearing blocking material when possible. Reasonable choice of the technical parameters, such as slow speed can not be too large. Strict implementation of control procedures, so that no load starting, empty parking; ensure continuous average feed.
