Haomei Machinery CHB Making Machine For Sale

Concrete Hollow Blocks (CHB) are the most widely used walling materials for residential and commercial construction, the standardization of their specifications directly impacts local masonry construction efficiency and building costs. Tailored to specific CHB specifications and market demands, Haomei Machinery has developed a series of CHB making machine for sale that cater to production needs ranging from small-to-medium workshops to large-scale building material plants. These machines are exported to over 30 countries and regions, capable of meeting diverse regional product standards and raw material conditions.



Equipment models and production capacities are tailored to different investment scales.
The entry-level QT4-15 model molds four standard 400×200×200mm CHBs per cycle (15–18 seconds), offering a stable single-shift (8-hour) output of 6,400–7,600 blocks with a main unit power of approximately 21.6 kW—ideal for small-to-medium investors entering the industry.
The flagship QT6-15 model molds six blocks per cycle with a single-shift output of 9,600–11,500 blocks, making it the most popular mass-production configuration in Southeast Asian and African markets.
The QT8-15 and QT10-15 models mold eight and ten blocks per cycle respectively, achieving single-shift outputs of 12,800–19,200 blocks; these are designed for large-scale plants with stable orders and distribution networks covering multiple cities.
The entire series chb maker machine supports rapid mold changes, allowing for switching between chbs of various wall thicknesses (4, 5, 6, and 8 inches) while remaining compatible with derivative products such as paving stones and slope protection blocks.

CHB molding process parameters directly determine the masonry performance of the blocks. The Haomei concrete hollow block making machine utilizes a combined table-vibration and pressure process, featuring a vibration frequency of 4000–4500 r/min, a rated excitation force of 80–110 kN, and a hydraulic system operating pressure of 16–21 MPa. Blocks produced via this process exhibit dimensional deviations within ±1.0 mm, verticality deviations of ≤1.5 mm, and drying shrinkage rates of ≤0.05%; the resulting masonry features uniform mortar joints and a significantly reduced rate of hollow spots in the plaster layer. The blocks cover compressive strength grades from MU5 to MU15 with dry bulk densities maintained between 1100 and 1300 kg/m³, balancing structural load-bearing needs with thermal insulation requirements. The core rods undergo high-frequency quenching, ensuring low demolding resistance and smooth internal block walls, which facilitates subsequent utility channeling and installation.

The configuration of the complete CHB production line centers on balancing raw material costs with labor efficiency. A typical setup includes a PL-series aggregate batcher (2–3 bins, ±1% weighing accuracy), a JS500/JS750 forced-action mixer, a belt conveyor, the main molding machine, an automatic pallet feeder, and a palletizing system. The entire line is centrally controlled via PLC, requiring only 2–4 operators to manage the full workflow from batching to palletizing. The equipment accommodates various local raw materials—such as river sand, crushed stone, fly ash, and slag—with fly ash inclusion rates reaching up to 30%–40%; in markets with high raw material costs, this ratio directly determines the product's price competitiveness.

Based on years of overseas delivery experience, the return on investment for CHB projects is closely linked to local construction cycles. New clients are advised to prioritize the QT6-15 standard configuration; it offers a moderate investment threshold and sufficient production flexibility to meet market growth in small-to-medium-sized cities over a 3–5 year period. During the plant layout phase, space should be reserved for a steam curing area, allowing for the rapid implementation of curing processes during rainy seasons or periods of low-temperature construction to ensure consistent delivery schedules. Haomei Machinery offers complete turnkey solutions—ranging from plant layout design to installation and commissioning—tailored to the CHB standards, raw material conditions, and production capacity requirements of the client's country.
