QT4-28 Semi Automatic Brick Making Machine

(1).Breif Introduction of QT4-28  Semi Automatic Brick Making Machine

The QT4-28 semi-automatic brick production line is similar with QT4-24. It mainly includes the following parts: mixer, conveyor, brick making machine, brick discharging platform, manual cart. The entire production line requires 4 workers to operate, and the operating area requires 60 square meters. The factory area takes into account the raw material placement area, machine placement area, finished product area, drying area, etc., and requires about 600 square meters. QT4-28 can produce bricks of different sizes and types, such as hollow bricks, paving bricks, curbstones, solid bricks, square bricks, etc. Basic Requirements for Start Up QT4-28 Hollow Block Making Machine

(3). The Operation Process of QT4-28 Brick Making Machine

1. First, a worker needs to feed the material into the mixer manually.The mixing cycle is about 60 seconds. There is an electric control cabinet to control the mixer and the conveyor belt. To reduce the wear on the barrel wall, an additional protective layer can be added to the barrel wall. There are three solid mixing arms, and the mixing blades on the mixing arm heads can be replaced. To save manpower, customers can choose to dig a pit and put the mixer into the pit, or build a small platform to feed the mixer horizontally.
2. After the materials are fully stirred, they are sent to the hopper above the brick making machine through a 6m long conveyor. The conveyor belt width is 550mm, the motor power is 1.5KW, and the weight is 550KG. The belt is a V-shaped rubber belt, which can increase friction when conveying materials and prevent materials from slipping. The transmission method is through a pulley, which reduces speed and has low cost. The V-belt needs to be replaced regularly.
3. After the material enters the hopper above the brick making machine, a worker operates the electric control cabinet to control the brick making machine to unload the material. Then use the equipped small shovel to manually spread the material, manually place the board, and then operate the electric control cabinet to make bricks. The up and down movement of the beam drives the material cart to move forward and backward, and at the same time completes the work of adding materials and pushing bricks. When the beam is raised, the main shaft cam pushes the pressing head body to push the pressed product out of the mold cavity. The material cart moves at the same time to push the ejected molded product through the mold cavity to the brick discharge platform. The workers then use carts to transport the bricks to the drying area. It takes a week to dry naturally, and the bricks are watered 2-3 times a week. QT4-28 is mechanical vibration type baking-free manual block machine. It has 2 sets of bottom vibration motor of 3 KW,  top vibration motor of 1 set 2.2 KW, Raw materials distributing motor of 2.2 KW, Top mould fall down motor: 1.1KW, Block mould lift motor: 3.0 KW.

 

(4) Theoretical Capacity of QT4-28 Brick Making Machine

Note：This is the theoretical output. The actual output is influenced by various factors. If the workers are skilled in their operations, the output will be higher.

(5) Raw Material (several popular proportion)

1. Standard concrete block: cement 9-12%,sand 40%,stone 45%,water 3%.
2. Light concrete block: cement 9-12%, slag 80-90% ,water 3%.
3. Cement 9-12%,sand 10-20%,stone 30-40%, slag 25-50%, water 3%.
4. Cement8-10%,sand30- 40%,stone 50-60%, water 3%.
5. Cement 8%,sand 60%,fly ash 30%, gypsum 2%. 

(6)QT4-28 Semi Automatic Brick Making Machine Advantages.

1. The price is low and the quality is excellent. It is easy to operate. The three vibration motors have strong power, and the bricks produced by this machine are even more sturdy.
2. Multi-functional in one device. The machine can produce various hollow or solid block-like objects as well as paving stones by changing the molds, thus meeting the diverse needs of customers.
3. The QT4-28 block making machine control PLC is almost full automatic (just need to press one button, the block will be formed ), so its operation is easy but output is big. So this this QT4-28 hollow block machine is also called ONE BUTTON BLOCK FORMING MACHINE.
4. QT4-28 Hollow Block Making Machine is improved from QT4-40 Manual Block Machine . the difference is there is a hopper on the block making machine, so the QT4-28 hollow block making machine can be matched with a belt conveying machine to conveying raw materials into the block machine hopper; another improvement is adding the raw materials distributing device to improve the working efficiency. so the QT4-28 block making machine size is bigger and can save one labor than QT4-40 Manual Block Machine.
