Restrictions: geographical conditions, mining conditions and technology, on-site hoisting capacity, transportation conditions

The length and height determine the board size; the width determines the board quantity.

Generally 6~8m3, the minimum imported one is 1m3

Common modules: height 600~1200, length 1000/1200/1600/1800/2000/2400 (600, 800, 1000 are modules), width generally 1200~2000

Basic restrictions: stone physical properties (hardness, brittleness, texture), quantity of the same type of blocks in the same batch, size of the blocks, cutting process (tool, size), lifting, packaging and transportation conditions, order quantity of the same type of finished product, order size Matching suitability

Physical properties: 1. The greater the hardness, the higher the processing difficulty, the higher the requirements for processing equipment, and the greater the loss of the cutter head during the process. 2. The higher the brittleness, the lower the material yield, and the more expensive the back panel reinforcement (glass fiber mesh bonding, back frame, laminate layer) will be. 3. Consistent texture is a requirement for general projects. Defects affect the yield rate. 4. The larger the size, the higher the corresponding yield rate, the higher the processing difficulty and equipment requirements.

Market characteristics: 1. The market chooses 600*1000 width as the basic plate type, and the prices are different for larger sizes. 2. The quantity of the same material is limited by pit mouth shipment and supplier purchase conditions. 3. Procurement content ratio of special-shaped materials 4. Requirements for stone protection

Processing conditions: 1. Equipment type and processing capacity limit the size of the finished plate; 2. The saw kerf directly affects the amount of material produced. For example, the thickness of the saw blade ranges from 0.5 to 1cm, plus an activity gap of 0.2 to 0.4cm, generally 0.8mm. 3. Normal cutting utilization rate: generally 90%, the cost price should be: land reclamation square price ÷90%;, water cutting 4. Special-shaped material nesting issues: typesetting algorithm, process limitations, texture influence
