Due to the requirement and the large storage of its raw material, hollow block machine is gradually playing an important role in block production industry. And in order to meet the standard requirement of block production, hollow block machine and its series adopt advanced technology to guarantee the quality and strength of blocks. Combined with national infrastructure development and series of policies of environment protection, this type of machine is well received by investors from twenty more countries over four continents.

When you choose the hollow block machine, you should know what types of hollow block machine for sale in the market. E.g. Automatic hollow block machine for sale/semi-auto, mobile/immovable, hydraulic/no hydraulic just vibration model.

1. Choose Types of hollow block machine

1) The degree of automation: Automatic /Semi-automatic

Auto model: QT4-15/QT6-15/QT8-15/QT10-15 is the automatic block production line.

Semi-auto and small concrete block machine for sale:

2)Mobility:Mobile/Immovable

Mobile model: QM4-45/QMJ2-45/QMJ4-45/QMJ4-30/QMY6-25/QMY10-25

3)Block forming type: Hydraulic pressure and vibration/Vibration

Hydraulic pressure and vibration model: QT3-20/QT4-15/QT6-15/QT8-15/QT10-15

Vibration model: LMT4-28、LMT4-35、LMT4-40.

2. To know Raw material and ratio for making the hollow block

The materials choosing is also important on hollow block making. You should get the correct ratio of hollow block, then the hollow block are the high quality.

  1. )Normally: fly ash 50%、gravel 35%、cement 8% and sand 7%
  2. )Or fly ash 50%、gravel 42%、cement 8%

Remark: the ratio of mixed material can influence the quality of block. Consult an expert if you are not familiar with it. Material ratio can be adjusted based on local condition.

 3. To know Working principle

After knowing the ratio of hollow block, then you should know the working principle of hollow block machine. Then you will choose the suitable model of hollow block machine.

1)Vibration formation: Mixed material transferred into hopper through belt conveyor, material feeding machine get mixed material into block machine under the control of material feeding motor(If color is required, paint feeding machine will be used after this step), machine starts vibration under the control of vibration motor, after certain seconds, block is formed and transported on pallet through pallet feeding machine into storage unit for curing under the control of pallet feeding motor. Thus one cycle of block production is complete.

Advantages: Uniform material feeding generates the block with compact structure and high density.

2)Hydraulic pressure and vibration formation:  Mixed material transferred into hopper through belt conveyor, material feeding machine get mixed material into block machine under the control of material feeding motor, upper mould presses down onto bottom mould under the control of hydraulic station, at the same time, machine starts vibration under the control of vibration motor, after certain seconds, block is formed and transported through pallet feeding machine into storage unit for curing under the control of pallet feeding motor. Thus one cycle of block production is complete.

Advantages:Tensile strength of block reaches 21Mpa. Block with high density、high freeze resistance、high permeation resistance、great insulation of noise and heat.

4.To confirm the Specification size of block.

What is the size of block you want to produce and is the size you chose the well received one?There are various size of moulds for various blocks. Some sizes of blocks listed as follow. Hollow Block(mm): 400*200*200、390*190*190、390*240*190、240*190*190,etc. Solid Brick(mm): 230*110*70、240*115*53,etc. Pavement Block(mm):200*200*60、250*250*60、300*300*60,etc. Blind Road Block(mm):250*250*60、300*300*60,etc. Curbstone(mm):500*100*150、500*350*150、1000*250*350,etc. Porous Block(mm):240*115*90、240*200*90,etc. You can contact us for more detailed images of block sample.

 

5.To confirm the capacity of hollow block machine.

It is important to know how many blocks you want to produce daily? Generally, machine with high efficiency would produce more yet cost more.For example, QT4-25C Hollow Block Making Machine can produce hollow block with size of 400*200*200mm 4800pcs/8hours、porous block with size of 240*115*90mm 13600pcs/8hours and pavement block with size of 200*100*40mm 32000pcs/8hours.

 6.Choose the hollow block machine factory.

You know there are many hollow block machine factory in china, some factories are very small, they have no block mould making workshop, they buy mould from other factory, and the steel may be not reached the standard. So you’d better choose the big block machine company. Lontto group is one choice for buying hollow block machine.
