Product Description.
Clay bricks:
Raw material: bauxite clinker is used as the main raw material, soft clay is the auxiliary material.
Its composition is Al2O3≥36%, Fe2O3≤0.5%.
Combined with clay (soft clay 190 mesh) and its main components for Al2O3 ≥ 34%, Fe2O3 ≤ 1.0%
Powder preparation: cooked bauxite material, into the crushing system. Sieve with 3.0mm screen.
Particle size requirements: ≥ 3mm 3-1mm ≤ 0.088mm 4-8% ≥ 60% ≤ 10%
Part of the screened material is obliquely ground into fine powder by Raymond machine.
Requirements for particle size: ≤0.088mm ≥95%
Before feeding, the clinker and fine powder are separately rested into the silo for reserve.
Clinker bauxite and clay are weighed separately and loaded into a bin for spare.
Mud preparation, clinker, fine powder, clay, water (plus)
Add material mixing, static mixing 15 minutes, the material shall not have mud and dry material. (Moisture can be adjusted according to the moulding situation)
Brick billet forming: load the material into the mould, use pressure and vibration to exhaust and press, according to the grade of high alumina bricks, adjust the pressure of the equipment, so that the brick body to meet the standards.
Drying: Place the moulded bricks in the drying room for natural drying and preheating drying by kiln, control the drying time and temperature to ensure the moisture inside the bricks evaporate fully.
Sintering: Push the brick billets from the drying room to the sintering kiln at regular intervals and under high temperature conditions, combine the material particles of the brick billets through high temperature sintering to form a dense crystalline structure, and control the time and temperature of sintering to ensure the mechanical strength and refractory performance of the high alumina bricks.
Cooling and packaging: Timing from the sintering kiln to the cooling section, cooling, control the cold time, after the cold time, push out from the kiln, according to the brick type, according to the customer's requirements for packaging.
