Mixing station control system is equipped with accurate batching machine equipment,甘孜专业JS750 mixing plantSeveral independent ingredient lines can be controlled at the same time, and each ingredient line can be set according to user requirements。Control system in addition to sensors,JS750 mixing plant用途All placement away from the site mixing plant central control room for centralized operation control, the system design has reached the expected goal。Mixing plant control system equipment functions have the following benefits: mixing plant control system ▪ high degree of automation ▪ Operation automation ▪ Simple operation ▪ high safety factor ▪ Easy maintenance

1, mixing system Mixing system by motor, reducer, a pair of open gear and chain drive, mixing device and mixing tank composition。The motor is mounted on the end face of the reducer, and drives the two horizontally configured mixing shafts to reverse equal speed rotation respectively through a pair of open gears and chain drives。The mixing shaft is supported in the groove mixing tank formed by welding steel plate。Each stirring shaft is equipped with six stirring blades, and the mixture in the stirring tank is driven by the stirring blades to make "mutual cutting and turning" operation and alternately move according to the spiral trajectory。The combination of horizontal eddy current and vertical reverse flow agitation makes the material get rapid and strong agitation。专业JS750 mixing plant用途Due to the small linear speed of the perimeter of the mixing blade, the energy consumption of the mixing concrete, the wear of the blade and the lining plate are much smaller than other mixers。The shape, quantity and arrangement of stirring blades are the main factors affecting the mixing quality and technical performance of the mixer。A special floating sealing device is provided for the connection of the mixing shaft and the two ends of the mixing tank。The sealing device is also equipped with a special oil feeder, the main mixing shaft rotates, and the oil feeder automatically supplies oil to each sealing part to ensure the lubrication of the mixing shaft shaft end seal and support。2. Feeding system Feeding system is composed of hoist, feeding rack, hopper, etc。When loading，Load the mixture to be stirred into the hopper，The starting winch motor drives the drum to rotate through the reducer，When the hoisting wire rope pulls the hopper up to a certain height along the loading rack track，A pair of rollers on the bottom of the hopper enter the feeder level fork，The door opens automatically，Feed the material into the mixing tank。3. The discharge device is equipped with a discharge door at two arcs on one side of the cylinder, which can be rotated around the horizontal axis to open and close the eyes through an electric push rod。The horizontal shafting at both ends is supported on a support seat fixed to the bottom of the mixing tank。The length of the discharge door is slightly shorter than that of the tank. When the discharge door is opened, most of the mix is discharged by its own weight, and the residual mix is forced out by the mixing blade, so that the discharge is clean and fast without segregation。The joints of the discharge door and the mixing tank are sealed with wear-resistant rubber strips, and the backing plate on the support seat can be adjusted to ensure the sealing after wear。4、 JS750 mixing plant用途Water supply system The water supply system is made of unipolar centrifugal pump and quantitative principle。Under the guise of adjusting the pointer on the water tank dial, different amounts of water can be supplied。The two spray pipes are located directly above the two mixing shafts。The inlet and outlet of the water tank is controlled by the joystick of the three-way valve。When the water tank is supplied, the three-way valve cuts off the water discharge pipe, and the water inlet pipe is closed when the water tank is discharged。5, rack The rack is composed of bottom frame, legs, railings, platform, ladder, etc。Except for the railing, the rest are connected by bolts to the rack, and the railing is inserted into the socket hole on the rack。6. Electrical system。

Types of concrete mixing Concrete mixing is divided into two types: manual mixing and mechanical mixing manual mixing strive to act quickly when mixing，The stirring time starts when water is added，It should generally comply with the following provisions: when the volume of mixing is below 30L, the volume of mixing is 4~5min(minutes). When the volume of mixing is 30L--50L, the volume of mixing is 5~9min. When the volume of mixing is 51L--75L, the volume of mixing is 9~12min，According to test requirements，Do slump measurement or specimen forming immediately。甘孜专业JS750 mixing plantAll operations must be completed within 30 minutes from the beginning of adding water。Mechanical mixing first pre-mix once, that is, first shaper, so as not to affect the mix ratio during formal mixing。Start the mixer, add stones, cement, sand to the mixer in turn, dry mix evenly, and then add water slowly, all the feeding time does not exceed 2min, after all the water is added, continue mixing for 2min。The mixture is unloaded from the mixer, dumped on the mixing catch, and then manually mixed for 1~2min, slump measurement or specimen forming can be done。JS750 mixing plant用途All operations must be completed within 30 minutes from the beginning of adding water。

The main characteristics of concrete mixing station are as follows: 1.专业JS750 mixing plant用途The combination structure, modular unit, installation, relocation is very convenient。2.Mixing machine and aggregate lifting adopts JS1000 type double horizontal shaft forced concrete mixer, which has good mixing quality and high efficiency。3.PLD1600 concrete batching machine is used for aggregate batching, which has accurate measurement and high production efficiency。4.JS750 mixing plant用途The powder is measured by electronic balance with high precision。5.The water is measured by electronic balance, and the batching precision is high。
