How To Scientifically And Reasonably Define The Production Capacity Of A Ready-mixed Concrete Mixing Station?

The production capacity of a ready-mixed concrete mixing station mainly depends on the size of the mixer (m3) (i.e., the rated mixing capacity per hour m3/h). When designing, in addition to considering the equipment manufacturer of the mixer, the structure, model, and performance of the mixer, the mixing capacity of the ready-mixed standard stationary concrete batching plant corresponding to the specifications of the concrete mixer is usually as shown in the following table, but this is the mixing capacity, not the production capacity of the ready-mixed 120m³ stationary concrete batching plant.

Because the production of ready-mixed concrete is different from other industrial products, ready-mixed concrete is a special commodity that must be used or poured in the template of the construction project structure within the specified time and under the conditions of meeting the relevant construction operation standards before it can be traded to the user. Therefore, its mixing capacity is first restricted by the construction organization, operation method, reasonable design, construction project volume, etc. in addition to the specifications of the mixer itself. Secondly, it is also restricted by the loading and unloading capacity and pumping capacity of the transport vehicle. The annual production capacity cannot be determined solely by the mixing capacity corresponding to the specifications of the concrete mixer. In addition, the concrete production line of the same specification mixer has different production capacity in different regions. It is mainly affected by the following factors:
First, the production of the ready-mixed 180m³ stationary concrete plant is intermittent production. There is a cycle for loading, unloading and mixing. It is an intermittent operation equipment. It is different from other industrial equipment in calculating production capacity;

Second, the ready-mixed concrete production enterprises in each region are affected by local climate and environmental conditions. The actual production days per year and the actual start time per day are different, and the actual operation rate is also different;

Third, the actual supporting capacity of transportation and pumping of each production enterprise is different; the environmental conditions of the transportation road, the transportation distance, whether the construction project site is spacious, etc. are different;

Fourth, the storage volume of raw materials of each production enterprise, the size of the floor area of ​​the stationary concrete mixing plant, the storage volume of raw materials, and the actual effective storage days for production use are different.

Fifth, the construction progress and engineering volume of construction projects in provinces, municipalities, prefecture-level cities, counties (cities, districts) are different; the amount of premixed concrete poured during most construction periods is often intermittent, and the busy and idle periods are uneven.

Sixth, the organization and construction management level of construction projects, the rationality of design, etc.

All of the above factors affect the normal mixing capacity of the premixed mobile concrete mixing plant and its annual production capacity.

Therefore, how to define the production capacity of the premixed concrete industry or enterprise in a certain area, based on the comprehensive factors of the above six aspects in the region, calculate or determine the production capacity of the premixed concrete industry or enterprise in a certain area is relatively scientific and reasonable.

Methods for defining the production capacity of a premixed universal mobile batching plant:

First, according to the past years (or normal production) of the 60m³ concrete batching plant, take the average value of the month or year, multiply it by the number of production days per year, and the annual production capacity of the mixing station.

Second, according to the normal transportation capacity of the premixed concrete transport vehicle, calculate the average annual transportation volume, multiply it by the number of vehicles that the mixing station has that match the driver, and calculate its annual production capacity.

The above two methods are general definition methods, which can be used as one of the bases for industry planning or industry management decisions in a certain area.

However, when it comes to the definition of production capacity of a certain enterprise, it is necessary to combine the above six comprehensive factors and the actual situation of the enterprise. It can be calculated more scientifically and reasonably by taking the factor coefficient method or the weight ratio of each factor affecting the mixing capacity.

In addition, it is very likely that a certain production enterprise will exceed the defined production capacity at a certain stage, which is also normal. Generally, it will fluctuate around the defined production capacity, but after averaging over the years (if no investment is increased), its production capacity will return to the defined range.
(For example) For a ready-mixed concrete mixing station in a certain county, according to the statistical summary data of the past years, the monthly production progress of a normal production year is: January - pouring concrete 10,000m3, February - pouring concrete 12,000m3, March - pouring concrete 15,000m3. April - pouring concrete 20,000m3, May - pouring concrete 25,000m3, June - pouring concrete 10,000m3. When defining the annual production capacity of the mixing station, it is more appropriate to use an average monthly production of 15,000 m3. If calculated based on 300 days, the annual production capacity of the mixing station is 150,000 m3.
