Different Volumes of Twin Shaft Concrete Mixers

1. Different Volumes of Twin Shaft Concrete Mixers Abstract: The popular models of twin shaft concrete mixers: JS500, Js750, JS1500, which are respectively called 4 bag concrete mixer, 1 yard concrete mixer, 2 yard concrete mixer. What are their parameters and how to choose a right one? Welcome to read this page. JS500 Concrete Mixer: 4 Bag Concrete Mixer With the development of society, the demand for concrete has kept increasing. Twin shaft concrete mixers are becoming more and more common. JS500mixer is a small model, which is also called 4 bag concrete mixer. How does it work? The working principle of the concrete mixer is to make the trajectories of the components of the mixing material in the mixing process intersect each other in the relatively concentrated area as much as possible and to maximize the mutual friction, creating the most favorable conditions for

2. the concrete mixture to achieve homogeneity. The mixing purpose of JS500 concrete mixer is to make the components uniformly macroscopically and microscopically, destroy the agglomeration of cement particles and promote the development of the dispersion phenomenon. The task of the 4 bag concrete mixer is to produce a strong flow and complex trajectory of the mixture, to produce a larger relative velocity between the particles and to produce collision and cause greater friction power. The mixing shaft of JS500 concrete mixer is equipped with 6~7 mixing blades. The mixing blades rotate at high speed in the mixing drum, which can quickly mix various materials to a large extent. The JS series mixer can be used as a mixing host of concrete batching plant for both engineering and commercial purposes. JS750 Concrete Mixer: 1 Yard Concrete Mixer JS750 concrete mixer is a main kind of twin shaft mixers. It is usually used as the host of HZS35 concrete batching plant. It is of reasonable structure, good mixing quality, short time, low energy consumption and low noise. The lining board and the mixing blades are made of wear-resistant alloy cast steel with high hardness and high toughness, which has a long service life. The main parts of the electrical control system are all imported components, with excellent performance and high reliability. 1 Yard concrete mixer maintenance regulations: Frequency: Every time  Check whether the body is stable.  Check whether the link bolts on the supporting arm of the blade and the mixing blade are firm.  Check whether the connecting bolts on the loading frame are firm.  Check Whether the pool is full and whether the pipeline is unblocked.  After ending work, clean the dust accumulation inside and outside of the mixing tank, discharge door and hopper, and rinse it with water.  Cut off the power supply and lock the electrical control cabinet.  Add lubricating oil to the lubrication point.  All water stored in the water supply system should be drained. Frequency: Every week  Check the wear of the wire rope and

3. apply a little lubricating oil to its surface. After the wire rope has worn to a certain degree, it should be replaced. Check the oil level of the gearbox, the oil quantity of the oil pump, and the condition of each lubricating part, and add lubricant to the hopper roller bearing and the lubricating bearing. Keep the water supply device clean to avoid clogging. Check and clean the suction valve. Check whether the rocker arm of the travel switch is loose, and adjust it if necessary. Check whether the contactor contacts in the electrical box are damaged. Frequency : Every month  Check the hoisting brake and make appropriate adjustments.  Check the water pump and throttle valve for preventing water leakage.  Check the open gear and apply lubricant, and adjust the belt tension.  Check the wear of the blades and lining plate, and replace it if it is worn out.

Then what are the main parameters of the concrete mixer used? 1. Rated capacity  Feeding capacity refers to the volume of dry material that is loaded into the mixing drum without mixing.  The discharge capacity is the main performance index of the mixer, which determines the productivity of the mixer and is an important basis for selecting the mixer. 1 yard concrete mixer refers to that the output is 1 yard(about 0.76 m3). 2. Working circle  Feeding time. The time from the start of the hopper lifting to the complete discharge of the mixed dry material into the mixing drum.  Discharging time. The time taken for the concrete mixture not less than 90% (for rotary mixer) or 93% (for twin shaft mixer) of the nominal capacity to be discharged from the mixing drum.  Mixing time. The time is from the entrance of mixed dry material to the the finish of homogeneous concrete. It is about 35s-45s. For the 1 yard mixer, the mixing time is about 40s. 3. Mixing speed

4. The mixing speed is the rotating speed of the mixing drum, of which the unit is r/min. The rotation speed of twin shaft concrete mixer is generally 20~36r/min. 4. Productivity The productivity of the 1 yard concrete mixer for sale is determined by the time required to prepare 1 batch of concrete and the discharge volume of one batch. The calculation formula is as follows: Q＝3600V1ψ1/(t1＋t2＋t3) Where Q- productivity, m3/h; V1- feeding capacity, m3; t1- Each feeding time, s; t2- Each mixing time, s; t3- Each discharge time, s; ψ1—Discharge coefficient. It is generally 0.65～0.7 for concrete and 0.85～0.95 for mortar. JS1500 Concrete Mixer: 2 Yard Concrete Mixer JS1500 concrete mixer, also called 2 yard concrete mixer ,is a large model of twin shaft concrete mixers. It consists of mixing system, loading system, discharging system and electrical system. There are some FAQs about this model for your reference. 1. What does js1500 mean? A: According to industry regulations, JS stands for double horizontal shaft compulsory mixing.

5. 1500 means the discharging capacity of the concrete mixer is 1500L, which is often refers to as 1.5 cubic meter or 2 cubic yard. 2. What’s the discharging height of JS1500 concrete mixer? At present, the discharging height of most JS1500 concrete mixer is 3.8 meter. However, as the height of the concrete mixer truck is increased, its discharging height has been increased to 4.1 meter correspondingly. It can make changes according to the customer’s requirements. 3. How much is the JS1500 Concrete Mixer? Different configuration and different manufacturers will have a different concrete mixer price. Some JS1500 concrete mixers is driven by single motor while some choose dual motors. There are two feeding methods: lifting bucket and conveyor belt. The general JS1500 concrete mixer is about 21,000 dollars. 4. What Is the application scope of JS1500 concrete mixer machine for sale? It is suitable for various large, medium and small prefabricated component factories and highways, bridges, water conservancy, ports, docks and other industrial and civil construction engineering projects. It can mix dry hard concrete, plastic concrete, fluid concrete, light aggregate concrete and various mortars. It can be used alone or form a simple concrete batching plant with PLD1600 batcher. I also can be used as the mixing host of HZS75/HZS90 concrete mixing plant.
