1.Optimized Vibration‑forming Technology for Hollow Products with Complete Hollow Cavities
The machine adopts table‑mounted dual‑shaft inertial vibrator, vibration frequency of 4500‑5100 times per minute and vibration acceleration of 15‑20 g. Combined with pre‑vibration plus main‑vibration composite molding logic, it solves common defects such as uneven aggregate distribution, cavity shortage and honeycomb surface on hollow blocks. High‑frequency vibration fully expels air bubbles inside mold cavity. The outer walls and ribs of hollow blocks are well filled with raw materials. Compressive strength of finished blocks can exceed 15 MPa, meeting MU10 and MU5 grade standards for hollow blocks. Three‑layer rubber spring vibration‑isolation structure suppresses vibration transmission and avoids offset of mold cores caused by heavy vibration. It guarantees stable hollow rate (perforated block hollow rate ≥25%) and wall‑rib thickness conforming to national standards, greatly reducing reject rate of hollow bricks.
2. Smooth Synchronous Demolding Mechanism to Prevent Hollow‑brick Damage during Ejection
High‑precision four‑column guiding sleeves realize vertical synchronous movement of mold box and pressing head. During hollow block production, uniform vertical demolding avoids pulling‑damage to green bricks caused by mold offset. Mold cores are fixed inside mold box, effectively preventing cavity collapse, wall cracking and corner chipping which frequently occur on hollow concrete products. After replacing hollow‑block or perforated‑brick molds, operators can quickly calibrate clearances among mold box, pressing head and pallet to ensure even compression on every green block. Strict electrical interlock logic ensures demolding action can only start after feeder trolley fully retracts, avoiding mechanical interference to hollow brick forming and demolding.
3. Strong Mold Compatibility for Full‑series Wall Hollow Blocks
The machine is compatible with complete hollow‑product molds from manufacturer. It can produce two major series of hollow blocks (190 mm width & 90 mm width), load‑bearing perforated bricks (240×115×90 mm), non‑bearing hollow bricks and universal filler blocks. Simply changing molds enables switching among hollow wall blocks with different hollow rates and wall thicknesses. Mold positioning structure is solid with high‑precision core pins to guarantee accurate hollow cavity geometry. Wear‑resistant mold material, replaceable feeding teeth, sealing strips and brushes help lower mold‑replacement cost. Custom‑built hollow‑block molds according to customer drawings are available to satisfy local building code requirements.
4. Wide Raw‑material Adaptability for Hollow‑block Formula to Cut Production Cost
Maximum aggregate size shall be ≤10 mm, and aggregate particle shall not exceed half of hollow block rib‑wall thickness, so as to protect mold cores from heavy‑particle impact. A large proportion of industrial residues including fly ash, coal gangue and furnace slag can be adopted to manufacture both load‑bearing and non‑bearing hollow blocks. Reference weight‑based mix proportions for hollow blocks and perforated bricks are offered in user manual. Users can adjust formulas with local sand, stone and waste residues to reduce cement consumption while keeping target strength. Local‑material utilization complies with solid‑waste recycling policy and significantly lowers raw‑material cost for wall block factories.
5. PLC Intelligent Control System with Storable Hollow‑brick Process Parameters for Easy Operation
PLC plus touch‑screen HMI allows independent setting of pre‑vibration duration, main‑vibration time, pressing holding time and feeding cycles specially for hollow block production. Process parameters for different hollow‑block sizes can be saved as brick‑number profiles for one‑click recall during mold change, avoiding repeated debugging. Both manual and automatic modes are available. Operators can run single‑step manual cycles to observe hollow brick forming status and optimize technical parameters. Built‑in fault diagnosis and action interlock prevent accidental collision and damage to hollow‑block mold cores. Operators can master mass hollow‑block production after short‑term training.
6. Robust Mechanical‑hydraulic System for Long‑time Continuous Hollow‑brick Mass Production
Total machine weight reaches 6200 kg with rigid frame resisting deformation under long‑time heavy vibration for hollow block manufacturing. Independent integrated hydraulic power unit is isolated from host‑machine vibration and dust. Rated hydraulic pressure is 16 MPa to deliver stable compaction force for hollow blocks. Oil cooling and filtering system controls oil temperature during non‑stop operation, preventing uneven block strength caused by pressure fluctuation. The full automatic workflow: pallet feeding‑molding‑block discharging runs coherently. It produces 6 pieces of 390×190×190 mm hollow blocks per pallet with molding cycle 15‑25 seconds, hourly output up to 1080 pcs, well‑suited for medium‑small factories for wall‑block mass supply. Lubrication points are clearly marked. Regular maintenance for vibration box, guiding sleeves and feeder trolley bearings minimizes downtime.
7. Complete After‑sales Support for Turn‑key Hollow‑block Project Delivery
The whole unit is delivered in five split modules for convenient transportation. After on‑site positioning, leveling, wiring and piping, manual‑joint‑automatic test‑run can be performed directly for hollow‑block formula commissioning. The supplier provides reference hollow‑block raw‑material ratios, mold installation guidance and on‑site operator training, teaching troubleshooting for common hollow‑brick defects such as cavity shortage, insufficient strength and cavity collapse. Under proper operation & maintenance, manufacturing defects are covered by free repair & replacement within half‑year after delivery. Original hollow‑block molds, mold cores, sealing parts and vibration‑box spare parts are continuously supplied to keep hollow‑block production line running steadily.
