Concrete mixer principle of selection

Concrete mixer principle of selection
(1) the production scale

Depending on the size scale of production to determine the concrete mixing equipment production capacity. The annual output of 200 000 m3 or less, concrete mixing plant productivity is generally not less than 90m3 / h; twin-shaft concrete mixer zz5257gjbn3641 the annual output of 20 case 300 000 m3, concrete mixing plant productivity typically 120m3 / h; the annual output of more than 300,000 m3 of concrete mixing equipment productivity in general to 150 m3 / h or 200m3 / h.

(2) construction site

Depending on the size of the construction site, choose concrete mixing or concrete mixing station. Selection concrete mixing plant, aggregate time enhance productivity mixer mixing plant of the same capacity than the high, the overall shape neat appearance, small yard area, good production environment, manufacturing, installation cycle long, high one-time investment costs. Selection of concrete mixing station, aggregate need two boosts, flexible layout, fabrication, installation cycle is short, low one-time investment costs, but large yard area, the production environment is poor.

(3) Auxiliary Equipment

Attachment device according to the situation to choose the specifications of concrete mixers and working dimensions. Mixer truck loading capacity and discharge capacity should match the mixer, improper matching will affect the work efficiency. Feeding capacity loader and concrete mixing station should Feeding height dosing station match.

(4) management functions

If using intensive network management, network management should consider concrete mixer functions of the device, to avoid future upgrades difficult.

(5) The equipment technical performance

Mainly from the advanced nature twin shaft js750 mini concrete mixer of the equipment, reliability, quality and versatility of several considerations. Equipment should have advanced working principle, high degree of automation, powerful management and good environmental performance characteristics. Equipment should be configured excellent, reliable control, applicability, good service performance. Also, consider the high accuracy, good mixing quality, high efficiency, low energy consumption, greater use of standard parts, interchangeability good.

(6) supplier credit

Including installation and commissioning is strict; technical guidance and training are in place; timely service; spare parts supply is sufficient.

(7) The cost performance

The pursuit of a comprehensive technical performance of equipment is unwise and unnecessary investment will increase, but only the pursuit of low investment and reduce the cost of equipment and technology to increase the use of performance will bring, this approach is not desirable. Imported equipment on the domestic market higher overall performance, but the price is more expensive. Domestic equipment Several well-known brands, jzm750 concrete mobile cement mixer although overall performance can not be compared with the imported equipment, but the configuration of key parts are generally imported components, the main job performance is not much worse than the imported equipment, the price is much lower. More reasonable approach is to select the appropriate cost performance.

Concrete workstation atmospheric effects on the environment:

Concrete mixing station itself is not dust, mainly workplace management and ancillary venues impact every day loading and unloading dust is very serious, if the glowing water wet ground, basically there is no dust. Each one car pulled out of the project go through a flushing device, from top to bottom of the vehicle clean, otherwise it will not environmental standards. When concrete filling car to the loading wheel will bring up billowing dust, open dumps sand heap under the effect of wind also raised a lot of dust. So the enterprise should sprinkler. Piled raw space should be closed, the site entrance needs to harden. It will effectively reduce the management so that bit the dust after the maximum to avoid the impact on the atmosphere.
