The naming of concrete batching plant model is based on the size of the discharge. For example, HZS120 is 120 cubic meters per hour. The typical specifications of the batching plant are HZS60, HZS90, HZS120, HZS180, HZS240, HZS270, HZS300, HZS300, etc.
Group code HZ stands for concrete batching plant. HL stands for concrete mixing building.
The number of host units is standardized by Arabic numerals. The number of single hosts can be omitted.
Mixer type code S is double horizontal shaft type, D is single horizontal shaft type, T is planetary type, W is vortex slurry type, F is conical inclined discharge type, and Z is conical reversed discharge type.
The main parameter code is the production capacity, unit m³/h.
The naming of concrete batching plant model HZS180 as an example
H Z S 180
(1) H- means concrete
(2) Z – means the batching plant. If it is a mixing building then it is represented by the letter L.
(3) S – means the configured mixer (host) is a forced double horizontal shaft machine. If it is a compulsory single horizontal-shaft machine, it is represented by the letter D.
(4) 180 – means that a 3m³ mixer theoretically produces one 3m³ of ash a minute. One hour to play ash 60 times, the corresponding output of concrete is 3 × 60 = 180 m³.
If “2” is added in front of these symbols, it means that the configuration of this mixing plant is double units (double lines). For example, a double-unit 180 station is indicated as 2HZS360.
In fact, an HZS180 concrete batching plant production line cannot produce 180m³ of concrete per hour under normal circumstances. In GB/T10171, it is stipulated that if a periodic mixing plant uses a forced mixer, the number of working cycles is: when the host is 1.5m³ to 2m³, it should be ≥ 40 times/h. In the case of a 120 station configured with a 2m³ machine, the minimum ash output should be ≥ 80m³/h, while when the host is greater than 2m³ to 4m³, it should be ≥ 35 times per hour.
The product of the batching plant is ready-mixed (fresh) concrete. The so-called ready-mixed concrete refers to the qualified homogeneous concrete that is mixed by the concrete mixing plant and not pounded, which is also generally referred to as commercial concrete. And the so-called homogeneous concrete refers to concrete in which the relative error of mortar density is not more than 0.8% and the relative error of coarse aggregate mass in a unit volume of concrete is not more than 5%.
The main difference between a batching plant and a mixing building
A batching plant is divided into the main building and a ground silo where aggregates are stored. If the ground silo where the aggregates are stored is relocated on top of the main building, it is a mixing building. Statistically speaking, the number of customers building batching plants is much higher than that of mixing buildings. The reason is that the total investment for building a batching plant is less and the construction time is shorter.
