Applications:
Bauxite clinker is mainly used for manufacturing high-quality refractory products, refractory castable, sagger, kiln furniture, crucibles,precision casting industrial,refractory ceramic,ceramic fiber products, etc.
Bauxite customization process
I. Communication and confirmation of requirements
(1) Initial contact
When customers get in touch with bauxite suppliers, they can express their interest in bauxite products by telephone, email or online platform. Suppliers will provide customers with information such as product catalogue, basic specifications and price range, so that customers can have a preliminary understanding of the types and general situation of products.
The customer explains his project requirements to the supplier, including the use of bauxite (such as making refractory bricks, castable materials, ceramic fiber products, etc.), the estimated purchase volume and the approximate delivery time requirements.
(2) detailed requirements communication
According to the initial needs of customers, suppliers arrange professional and technical personnel to further communicate with customers. Understand the specific technical requirements of customers for bauxite, such as the content range of alumina (Al₂O₃) in bauxite, whether specific mineral composition (such as high content of mullite, corundum, etc.) is needed, and the physical performance requirements of products (such as bulk density, fire resistance, etc.).
Confirm the granularity requirements of bauxite. Customers may need products with different particle sizes, such as granular (0-1mm, 1-3mm, 3-5mm, etc.) or powdery (-200 mesh, -270 mesh, -325 mesh, etc.), and suppliers need to clarify these particle size specifications.
To discuss the quality standards of products, customers may require to meet specific international standards (such as KS, JIS, ASTM, DIN, etc.) or internal standards of enterprises, and suppliers need to confirm whether their products can meet these standards.
II. Sample Provision and Testing
(1) Sample preparation
According to the customer's demand, the supplier selects bauxite samples that meet the basic requirements from the inventory. If there is no product in stock that fully meets the customer's requirements, the supplier may first conduct small-scale customized production to provide samples.
The packaging of samples should meet the transportation requirements to ensure the integrity and representativeness of samples during transportation. Samples are usually packed in sealed plastic bags or small packaging bags, and the sample number, product name, basic specifications and other information are marked on the outer packaging.
(2) Sample detection
After receiving the sample, the customer will conduct a series of tests. The test items may include chemical composition analysis (such as the content of alumina, silica, iron oxide, etc.), particle size distribution test, physical properties test (such as bulk density, water absorption, compressive strength, etc.) and mineral composition analysis.
If the customer has no testing ability, the supplier can provide an authoritative third-party testing report or assist the customer to send the sample to a professional testing institution for testing.
III. Formulation of customized scheme
(1) technical scheme formulation
According to the sample test results and customer requirements, the supplier's technical team makes detailed customized technical solutions. We will specify the production process parameters of bauxite, such as calcination temperature (generally 1450-1600℃, but the specific temperature will be adjusted according to the grade of bauxite and customer requirements), calcination time, raw material ratio and so on.
Determine product quality control standards and testing methods to ensure that customized products can meet customer quality requirements in the production process. For example, it is stipulated that granularity analysis, chemical analysis and physical performance test should be carried out regularly in the production process.
(2) Cost accounting and quotation
The supplier conducts cost accounting according to the customized scheme, including raw material cost, production and processing cost, testing cost, packaging cost and transportation cost. Cost accounting should be accurate to ensure that suppliers can make profits and the quotation is competitive with customers.
Submit a detailed quotation to the customer, which will list the unit price, total price, payment method (such as T/T, L/C, Western Union, etc.), delivery date (usually 7-20 days after confirming the order) and transportation terms (such as FOB, CIF, etc.).
IV. Contract Signing and Production
(1) Contract signing
After the customer confirms that the quotation and customization plan are correct, the two parties sign a sales contract. The contract will specify the product specifications, quantity, quality standards, price, delivery time, payment method, liability for breach of contract and other terms.
After signing the contract, the customer usually needs to pay a certain proportion of advance payment, such as 30%-50%, as the down payment of the order. The payment method of advance payment can be carried out according to the payment method agreed in the contract.
(2) Production arrangement
The supplier arranges the production plan according to the contract requirements. If it is necessary to adjust the production process, such as changing the parameters of calcination equipment (such as vertical kiln, inverted flame kiln or rotary kiln) or changing raw material suppliers, the suppliers will conduct trial production in advance to ensure the product quality meets the requirements.
In the production process, the supplier's quality control department will strictly follow the quality control standards in the customized plan for testing. Conduct sampling inspection on each batch of products, including particle size analysis, chemical composition detection, physical performance test, etc., to ensure that the products meet the contract requirements.
V. Product Packaging and Transportation
(1) packaging
According to the contract and the characteristics of the product, the supplier chooses the appropriate packaging method. Common packaging methods include 1000kg large bag packaging or 25kg small bag packaging (plastic woven bag or kraft paper bag), and tray packaging or direct packaging into large bags according to customer requirements.
Attention should be paid to the protection of products during packaging to prevent products from being affected with moisture, pollution or damage. After the packaging is completed, the product name, specifications, production date, manufacturer and other information should be marked on the packaging.
(2) Transportation
Suppliers arrange transportation according to customers' designated ports (such as Qingdao Port and Tianjin Port). According to the quantity of products and the requirements of customers, choose the appropriate transportation mode, such as container transportation.
A 20-foot container can carry about 24 tons of bauxite, and a 40-foot container can carry about 28 tons. The supplier will communicate with the freight forwarder in advance to arrange the packing, customs declaration and transportation of the goods.
VI. Delivery and after-sales service
(1) Delivery
Within the delivery date agreed in the contract, the supplier will transport the goods to the designated port and go through the relevant export procedures. After the goods are loaded, the supplier will inform the customer in time and provide the customer with documents such as bill of lading, invoice, packing list, quality certificate (such as CO, CE, COA, test report, etc.).
After the customer receives the goods, they will accept them. The acceptance contents include the quantity of goods, the integrity of packaging and whether the quality of products meets the contract requirements.
(2) After-sales service
If the customer finds product quality problems during the acceptance process, the supplier will negotiate with the customer to solve them in time. Depending on the severity of the problem, it may be handled by means of replenishment, return and compensation.
