Key Features

High Production Efficiency: The molding cycle of a medium-sized cement brick making machine is generally between 15-35 seconds. It can produce thousands of bricks per hour, meeting the needs of medium-scale production.

Diverse Product Range: By changing the molds, it can produce various products such as cement bricks, hollow bricks, paving bricks, slope protection bricks, and curb stones, suitable for different construction scenarios.

Different Levels of Automation: There are semi-automatic and fully automatic types. Semi-automatic brick making machines require manual intervention in some steps, such as feeding and brick output; fully automatic brick making machines automate processes such as raw material conveying, mixing, molding, and stacking, saving labor costs.

Robust and Stable Structure: Typically uses a steel frame structure, combined with a hydraulic system and a vibration system, ensuring it can withstand significant pressure and vibration during production, guaranteeing the stability and durability of the equipment.

Below is a Q&A format addressing frequently asked questions about medium-sized cement brick making machines, including selection, installation, operation, troubleshooting, and routine maintenance. This allows for quick understanding of key information. Details are as follows:
**Selection Related:
Q: What production scenarios are suitable for medium-sized cement brick making machines?
A: Suitable for small and medium-sized building material factories, municipal engineering supporting production sites, and rural building material processing points. It can meet medium-scale production capacity needs and produce various brick types such as hollow bricks, paving bricks, and slope protection bricks. It is suitable for supplying building materials for construction, road paving, and community landscaping projects.

Q: What parameters should be prioritized when selecting a machine?
A: The core parameters to consider are the molding cycle (generally 15-35 seconds for medium-sized production capacity), maximum pressure (affecting brick density), and power (related to energy consumption and production stability). Simultaneously, pay attention to mold compatibility to ensure flexible switching between required brick types.

Installation Related:
Q:What are the site requirements for installing a medium-sized cement brick making machine? A: A flat, firm site should be selected, avoiding loose soil underneath. A storage area for raw materials should be reserved, and rain and moisture protection facilities should be planned. The power supply line distance should also be reasonable for easy operation and maintenance later.

Q: What checks need to be performed before powering on after installation?
A: First, check if the oil pipe connection between the main unit and the pump station is secure. The oil tank should be filled to over 80% with 30# hydraulic oil. Then, adjust the motor rotation to ensure that the two motors in the vibratory box rotate in opposite directions, and the V-belt tension is appropriate. Finally, tighten all bolts and add standard lubricating oil to the reducer and other lubrication parts.

Operational Related

Q: What are the reference standards for raw material ratios during production?
A: The commonly used ratio for the base material is 1 part cement, 2 parts sand, and 5 parts stone powder, mixed to a semi-dry state, reaching a consistency where it can be formed into a ball by hand but crumbles easily when released. If producing colored bricks for the surface layer, the cement and sand ratio is 1:1, and the pigment added is 10% of the cement weight. The surface material must be kept dry to prevent sticking to the mold.

Q: What are the effects of mixing and vibration time on brick quality?
A: Insufficient dry mixing time will lead to reduced brick strength. Dry mixing for 20 minutes can increase strength by 15-23% compared to 10 minutes. Insufficient vibration time or vibration force will cause loose bricks and bulging in the middle. The time needs to be adjusted according to the equipment's vibration force to ensure proper compaction of the upper mold.

Troubleshooting Related

Q: What causes loose bricks and a high breakage rate? How to solve it?
A: It may be due to insufficient pressure on the upper pressure head; the pressure of the corresponding pressure regulating valve on the upper pressure head cylinder needs to be increased. It may also be due to excessively dry or wet aggregate moisture; the raw material moisture needs to be adjusted to the standard state. If the vibration force is insufficient, the pressure regulating valve corresponding to the lower mold cylinder can be reduced to release the vibration force of the vibrator.

Q: The motor is prone to overheating and burning out; how to troubleshoot this? A: First, check the voltage to ensure the high voltage is between 380V and 410V and the low voltage is between 330V and 360V during equipment operation, with no missing voltage. If the oil pump motor overheats, it's most likely due to excessive pressure in the main pressure regulating valve; gradually reduce the pressure until the motor runs smoothly. If the vibrator motor overheats, it may be due to solidified lubricating oil or high resistance; heat the lubricating oil to melt it or adjust the lubricating oil level.

Q: What should I do if the oil cylinder leaks or the pressure regulating valve fails? A: Oil cylinder leakage indicates a failure of the seals inside the cylinder; replace the seals with the corresponding model. Pressure regulating valve failure is often due to a damaged internal pressure spring; replace the pressure spring with the same model promptly to avoid affecting pressure control.

Daily Maintenance Related

Q: How to protect the mold during daily use? A: Avoid mixing large stones, rebar ends, and other hard objects into the raw materials to prevent scratching or damaging the mold. If the mold vibration amplitude exceeds 4mm, increase the lower mold pressure promptly to reduce impact between the mold and the vibrating table. Clean any residual cement from the mold after each shift to prevent it from hardening and sticking.

Q: What are the key steps for daily equipment maintenance? A: Before each shift, lubricate all moving parts and clean residual cement from parts such as material carts and silos; regularly check the tightness of bolts and the condition of hydraulic oil; in summer, the hydraulic station condenser should be activated to prevent the oil temperature from getting too high; during maintenance, the main power supply must be disconnected and a warning sign must be hung to avoid safety accidents.
