The Operating Instruction of Concrete Mixing Plant HZS120
Ⅰ. Introduction
HZS120 is a new type of concrete mixing plant. Its mainframe machine is Double Horizontal Shaft Concrete Mixer JS2000, and its automatic control system is composed of IPC (Industrial Personal Computer) and Programmable Controller. Through this system, various ratio of concrete can be mixed, with the average hourly productivity of 120m3/h and discharge height of 3.8m. HZS120 is suitable for medium scale engineering constructions of hydropower, highway, bridge, port, airport, ect., and the large and medium-sized concrete precast factories and commodity concrete production factories.
Concrete Mixing Plant HZS120 consists of many different parts, such as aggregate batching system, material conveying system, measurement system, stirring device, water supply system, additives supply system, pneumatic system and electric control system. The process is: the screw conveyor transports cement and fly ash in the cement silo into the weighing hopper; and the sand and stone in the aggregate hopper are put onto the horizontal belt conveyor through the arc door under the silo to have a weigh, and then, they are sent into the bin by the horizontal and inclined belt conveyor; the electric pump sends water and additives into their respective weighing hopper. Then, put all the batching into the mixer and mix the concrete. At last, discharge the mixed concrete into the transferring truck through the collecting hopper.
HZS120 is reliable and accurate. The mixed time is short and the quality is good. It has two methods of operation, manual and automatic method. HZS 120 can save 200 kind of concrete formulation, and be equipped with the printer, which is very convenient for production management.
To operate the plant correctly and improve the work efficiency greatly, the workers must read the full set of instructions carefully, and be trained before operating HZS 120.
HZS 120 Executive Standard: GB10172-88.
Our factory has established and implemented the quality system consistent with GB/T19001-2000-ISO9001:2000 standard.
