The answer is no. Cement accounts for about 10% of the total raw materials of concrete. It is a very important raw material for QT4-28 used concrete block making machine for sale to produce concrete bricks. However, the more cement is added, the better. The first disadvantage of adding too much cement is the increase in cost. The price of cement is higher than that of raw materials such as sand and aggregate. Excessive use of cement will greatly increase production costs. Secondly, adding too much cement when QT4-28 used concrete block making machine for sale produces concrete bricks will affect the molding of concrete bricks and may also cause the concrete bricks to dry and crack.
The answer is no. A QT4-28 used concrete block making machine for sale can produce a variety of brick types. You only need to install the corresponding molds. QT4-28 used concrete block making machine for sale can produce 8-inch concrete hollow bricks, 6-inch concrete hollow bricks, 4-inch concrete hollow bricks, solid bricks, standard bricks, pavement bricks, etc. In addition to these conventional-sized concrete bricks, customers can also customize molds according to market demand to produce unique brick types.
According to the production speed of QT4-28 used concrete block making machine for sale, the molding time is 25 seconds and the working time is 8 hours a day, then QT4-28 used concrete block making machine for sale needs 1000-1500 fiber pallets.
