Twin shaft concrete mixer mainly mix sand, pebble and cement evenly according to certain proportion. So it is important part in concrete machine, such as, concrete batching plant and concrete block machine . This page will introduce you two hot types twin shaft concrete mixers that widely used for block making: JS750 and JS500 twin shaft mixer. In addition capacity and discharge are various, working process is the same. So here I will take JS500 twin shaft mixer as an example and show you more details.

JS series twin-shaft concrete mixers consist of feeding, mixing, discharging, water supplying and electrical control system.
Mixing system consists of electric motor, belt pulley, reducer, exposed gear, oil supply device. Electric motor will bring secondary gear and reducer, two shafts of reducer through two pairs of open gears will bring two horizontal mixing shaft do reverse constant-speed rotation.
There are two horizontal mixing shaft, each shaft has mixing blades. There are side blades respectively on the mixing arms at both ends of the mixing cylinder, can scrape the concrete residue.
A sealing device is provided at the two ends of the mixing shaft and the mixing cylinder. There is a special oil feeder on the end face of the mixing cylinder to ensure the sealing quality.
Feeding part of twin shaft mixer for sale is made up of hoisting mechanism, feeding rack, hopper and feeding inlet. When feeding the materials, lifting and transmission system will drive the wire rope to climb up the feeding frame guide rail through the pulley traction hopper, when the hopper was lifted to feeding position, the front roller of the bucket bottom enters the horizontal branch road, and the bucket body continues to rise, forcing the bucket bottom and the bucket body have hinged shaft as the fulcrum to separate and open the material door. With the rising of hopper, materials door opens gradually, materials will be put into mixing cylinder through middle hopper.
Water supply system of twin shaft batch mixer is made up of water pump, throttle valve, cleaning and sprinkler. Throttle valve can adjust water flow, time relay will adjust the total amount of water.
Discharge system of twin shaft cement mixer comprises discharge door, air cylinder or hydraulic cylinder. There re three types of discharge methods: hydraulic, pneumatic and manual.
Hydraulic actuated discharge gate is stronger than pneumatic system to avoid the phenomenon of insufficient pneumatic opening
Manual operation lever is used for emergency unloading when temporary power failure and cylinder or hydraulic cylinder malfunction. It should be removed at ordinary times to prevent injury. Electric or manual installation is optional.
When working from high pressure gas to the cylinder, cylinder drive swing bar, so that the door around the bearing seat rotation, to open and close the door.
Electrical control lines of twin-shaft concrete mixers with air switches, fuses, thermal relays, with short circuit protection, overload protection.
All control buttons, air switch handles and indicator lights are arranged on the distribution box door, and equipped with a lock.
A protective door is provided outside the button.
The electrical components in the distribution box are installed on an insulating board, safe and reliable, easy to operate and maintain.
Mixing system in horizontal twin shaft mixer is a mixing shaft set in the cylinder horizontally or vertically, and mixing materials are forced to be stirred by rotating stirring blades. When working, the rotating shaft drives the blade to shear, extrude and reverse the
The mixing drum in twin shaft feed mixer does not move, but is forced to stir by the vanes on the rotating axis in the drum. The twin-shaft batch mixer has good quality and high production efficiency. But power consumption is large, and blade wear fast. Generally suitable for mixing rigid concrete.
Actually, there are two ways to find twin shaft mixer manufacturer: online and offline. If there is now manufacturer, company or supplier in your local area, you can search on google, bing and yahoo. There will are many results for your choice.
