White Cement Manufacturing

White cement is also called white Portland cement. The white cement process is a selection of raw materials, processing, calcination and other links. After these steps, the final product is white Portland cement to use in architectural decoration. The raw materials of white cement mainly include limestone, clay and silica. Compared with ordinary cement, it has higher strength and better acid and alkali resistance.

White cement making process

STEP1: Raw material preparation

The raw materials are crushed and screened through the crusher. It ensures the quality of the raw materials.
The powder of raw material is put mix machine in ratio, then mix and stir to ensure the quality and uniformity.

STEP2: Preheat

Preheating process is to control the temperature and atmosphere. This reached a certain temperature before calcining. The particle is put a rotary kiln to preheat. This is to remove the water and improve efficiency of subsequent calcination.

STEP3: Calcination

The cement usually adopts a rotary kiln for calcining, which could improve the cement quality and output. Raw material is calcined in a high-temperature kiln after preheating, this produce white cement clinker.

STEP4: Cooling And Grinding

The calcined cement clinker is cooled in a cooler to a comfortable temperature.
The cooled cement clinker is ground by a mill with enough gypsum to make white cement powder.

Cement Making Machine

Cement Crusher

The bulk raw material uses crushing equipment to cut suitable sizes for production.

Jaw crusher: It is mainly used for Primary crushing and coarse crushing processing in crushing. The volume is small and the operation is convenient.

Impact crusher: This equipment is usually used for scrap processing and crushing. It adopts the crusher principle in the process, and its product form is well. The proportion of needles is low.

Hammer crusher: This equipment has a crush function. It could break and form once, it is not only good in crushing effect, but also investment is low.

Mobile crusher: This equipment is a new crushing equipment, its volume is small and could be strong mobility. It is not restricted by the site.

Cement rotary kiln

A rotary kiln is commonly used for white cement. It could meet white cement needs of high temperatures and a long time in the process. The rotary kiln turns the powder into the cement clinker through heat treatment, and maturing and decomposing in the process. The rotary kiln adds the material from one end of the kiln. Finally fired into cement clinker under high temperature and output to the other end. Its heat energy is supplied by burning coal, natural gas, and other fuels.

Cement grinding mill

It is used for continuous grinding mixed material after crushing to get small particle. A cement ball mill is a core equipment, that is mainly used for second grinding after crushing. It is to put material into a container to grind and it is suitable for large-scale production of cement manufacturers. Cement vertical grinding is a new type of cement grinding equipment, mainly composed of a motor, reducer, grinding disc, and other parts. The vertical has low energy consumption, low noise, and long service life. It is suitable for small cement manufacturers. Roller mill is a special grinding equipment and it is composed of grinding rolls. The roller mill has high efficiency and low energy consumption. It is used for the rolling process.

Cement cooler

The material enters the cooler, the cooler rotates, driving material and air to fully exchange heat. At the same time, the material rotates with the cylinder. This sent the material from the feed end to the output end. Moreover, It ensures the material is cooled to below 200℃, and then finishes the cooling process.

Packing machine

The packing machine is used for packing cement, it reserves cement from the storage tank and puts the cement into the bag. Then it competes with a series of packaging processes such as sealing and printing labels. The packing machine is a core step of cement production, it could greatly improve efficiency.

The Use Of White Cement

Make decorative materials： the white cement could make kinds of decorative materials, such as artificial marble, colored floor tiles, colored wall tiles, colored plaster, decorative lines of various shapes, etc.

Patching material: Because the white color is similar to lots of decorative material. The white material is used for fixing the building holes and cracks.

Make sculptures and artwork: Because white cement has a fine texture and is uniformly white, artists and sculptors often use it to create sculptures and works of art.

Concrete：In modern buildings, white cement is used for cast-in-place concrete for exterior wall coating or painting to achieve an aesthetic effect.
