Cement fineness screening device

Abstract

The invention provides a cement fineness screening device. The cement fineness screening device comprises a protection device; a control panel is installed at the right side of the protection device, and a feeding device is installed on the top of the protection device; a mounting mechanism is mounted in the protection device, vibration motors are mounted at the front end and the rear end of the mounting mechanism, and three discharging devices are mounted at the bottom of the mounting mechanism; and three groups of material receiving devices are arranged, the three groups of material receiving devices are mounted in the mounting mechanism, and screening mechanisms are mounted at tops of the two groups of material receiving devices at the right side. According to the cement fineness screening device, when a driving motor rotates, a material blocking cover rotates, when a notch makes contact with a discharging port, cement flows into a screening cylinder at the left side from a discharging port, similarly, when the notch makes contact with the discharging port, the cement flows into a material receiving disc from the discharging port, and therefore classification screening of the cement is facilitated; and when the notch does not make contact with the discharging port, the cement in the screening cylinder is fully screened, the screening time is the same each time, and the screening precision and the screening quality are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of cement processing, and more specifically relates to a cement fineness screening device. Background technique [0002] Cement: powdery hydraulic inorganic gelling material, mixed with water to form a slurry, can be hardened in the air or in water, and can firmly bind sand, stone and other materials together. The mixture of early lime and volcanic ash and modern Lime pozzolanic cement is very similar to that of lime pozzolanic cement. Concrete made of crushed stones bonded with it not only has high strength after hardening, but also can resist the erosion of fresh water or salt water. For a long time, it has been used as an important cementing material and is widely used. Used in civil construction, water conservancy, national defense and other projects. [0003] For example, the patent with the application number: CN201810936539.6 discloses an impurity screening device before cement loading, including a s...
