Processing technology

There are four main consumption lines for granite processing: standardized board consumption line, thin board consumption line, rough decorative board consumption line, and irregular board consumption line.
1. Processing process of granite standard plate
Use a crane to load the raw materials onto a waste truck, which is then transported by a shuttle truck to the working position of a frame type sand saw to saw and cut them into rough boards. The boards are then processed into smooth boards through processes such as grinding, polishing, and cutting, and finally inspected, packaged, and stored. The detailed process is as follows:
Raw material hoisting → sawing → washing and inspection → rough grinding → fine grinding → fine grinding → polishing → cutting and repairing → inspection and packaging
2. Processing technology process of granite thin plate
Granite sheet processing is an automatic processing assembly line, with each process connected by rollers, unloaders, and flippers. The process is as follows:
Raw material hoisting → sawing and cutting into thin plates → truncation → grinding and polishing → cutting → grinding, chamfering, milling groove repair, cleaning, drying → inspecting packaging
3. Processing process of granite rough decorative panel
Send the semi waste granite rough board through the rolling track to the automatic chiseling machine (select the cutting head according to the required pattern thickness), and the cutting head chisels various required rough decorative patterns according to the predetermined trajectory. If a singeing board is required, send it to an automatic singeing machine for processing. The process is as follows:
Semi waste rough board → chiseling or burning → cutting → inspecting packaging
4. Process flow of irregular plate processing
Design and produce templates according to users' special requirements for the shape and specifications of granite slabs, such as circular and elliptical tabletops, elliptical hole bathroom countertops, flower window edges, etc. Then, use a replica milling machine to process the required shape on the semi-finished slab according to the template shape (or pre-set program on the microcomputer). The process is as follows:
Semi scrap board → Edge cutting → Irregular milling → Drilling → Grinding and chamfering → Inspection and packaging
Artificial marble is composed of modified resin and crushed stone, and is neutral or slightly alkaline. Artificial stone has a dense structure, resulting in small pores and a low probability of exhibiting symptoms. In terms of protection, the main goal is to prevent pollution. Its advantage is that it can adjust the color and is conducive to decorative finishing. Its defect is insufficient hardness and inconsistent luminosity. According to the raw materials and consumption techniques used, it can generally be divided into four categories:
Cement based artificial marble is made by using various types of cement as binders, sand as fine aggregates, and crushed marble, granite, industrial waste, etc. as coarse aggregates. It is processed through batching, mixing, molding, pressure steam curing, polishing, and polishing, commonly known as terrazzo.
Polyester based artificial marble is made by mixing unsaturated polyester as a binder with quartz sand, marble, calcite powder, and other materials, casting them into shape, and then solidifying them under the action of a curing agent. It is then processed through demolding, drying, polishing, and other steps to produce the desired artificial marble. China often uses this method to consume artificial marble.
Composite artificial marble is composed of inorganic materials and organic polymer materials. After bonding the fillers with inorganic materials, immerse the green body in organic monomers to polymerize under certain conditions. For the board, the bottom layer is made of low-cost and stable inorganic materials, and the surface layer is made of polyester and marble powder.
