90-110 TPH Bauxite Sand Washing Machine in Sumatra Indonesia – A Strategic Investment for the Growing Alumina Industry

Why a 90-110 TPH bauxite sand washing machine in Sumatra Indonesia is a strategic investment for mining operators and alumina producers

Indonesia is undergoing a transformative shift in its bauxite industry. The country currently has 78 operating bauxite mines, with total production reaching approximately 16.8 million tonnes in 2024. Bauxite production is projected to jump 89% to 5.3 million wet metric tonnes in 2026, while overall bauxite demand is expected to reach nearly 25 million tonnes, driven by rapid refinery expansion. This growth is part of a broader government push to process raw materials domestically rather than exporting them, creating significant opportunities for operators investing in processing capacity. Sumatra, with its strategic location and growing industrial infrastructure, is emerging as a key hub for bauxite processing. For mining operators and alumina producers looking to capitalise on this booming market, investing in a 90-110 TPH bauxite sand washing machine in Sumatra Indonesia is a strategic move. At OCP Mechanical Company, with over 40 years of manufacturing experience, we offer factory-direct sand washing machines engineered for bauxite applications, providing transparent pricing and customised solutions for the Indonesian market.

Understanding bauxite and its washing requirements at 90-110 TPH

Bauxite is a naturally occurring material composed primarily of aluminium hydroxide minerals, along with clay, silica, and other impurities. In its raw state, crude bauxite typically contains significant quantities of clay and fines that must be removed before the ore can be processed in the Bayer refining process. Most bauxite mining companies in Indonesia have already been implementing washing methods using wet screening in trommel screens and vibrating screens after crushing the ore. However, as production scales up and quality requirements tighten, operators need more efficient, higher-capacity washing solutions. A sand screw washer is the ideal choice for bauxite washing because it provides effective scrubbing, classification, and dewatering in a single unit. For a 90-110 TPH operation, the washer must be capable of handling the high clay content typical of Indonesian bauxite while delivering a clean, specification-grade product for the alumina refinery. The screw diameter, tank length, and water flow rate are all critical factors that affect both washing efficiency and throughput. When you evaluate a 90-110 TPH bauxite sand washing machine in Sumatra Indonesia, you should consider the washer's ability to handle the feed characteristics – including the clay content, particle size distribution, and moisture levels – and to produce a final product that meets the requirements of the Bayer process. Our Type S sand washing machine is engineered for bauxite applications, featuring a heavy-duty spiral shaft with replaceable wear shoes, a variable frequency drive for precise speed control, and a water recirculation system that reduces fresh water consumption. All product specifications, including capacity and power ratings, are continuously updated; for the latest parameters, please consult our online customer service. By selecting the right washer, you ensure consistent product quality and compliance with refinery specifications.

Sumatra's strategic position in Indonesia's bauxite processing industry

Sumatra is emerging as a critical hub for Indonesia's downstream bauxite processing ambitions. The island is home to PT Inalum, Indonesia's only aluminium smelter, located in North Sumatra. The government is actively encouraging the development of domestic processing capacity, with aluminium smelting facilities in Sumatra playing a key role in the nation's industrial strategy. Kabantara Group is also partnering to build an 800-hectare smelter on the island, representing a significant investment in Sumatra's bauxite processing infrastructure. The development of these processing facilities creates sustained demand for washed bauxite, making Sumatra an attractive location for bauxite washing operations. For aggregate producers and mining contractors, investing in a 90-110 TPH bauxite sand washing machine in Sumatra Indonesia allows you to capitalise on this growing demand while reducing reliance on exporting raw ore. The strategic location provides access to major shipping routes and proximity to end-users. Our Type S sand washing machine is designed to produce specification-grade washed bauxite that meets the requirements of alumina refineries and smelters.

Key features of a 90-110 TPH sand washing machine for bauxite

When you evaluate a 90-110 TPH bauxite sand washing machine in Sumatra Indonesia, several critical features should guide your selection. The screw diameter and length determine the capacity and the degree of washing; for 90-110 TPH, a screw diameter of 36-42 inches and a tank length of 22-28 feet is typically required. The screw flighting should be made of high-strength steel with replaceable wear shoes to extend service life in abrasive bauxite applications. The water system is equally important – an efficient recirculation system can reduce fresh water consumption by up to 70 per cent, which is a significant advantage in regions where water may be scarce or costly. The weir design and adjustable overflow ensure that the fines and clay are effectively removed while retaining the desired sand fraction. The variable frequency drive allows you to adjust the retention time to match the feed characteristics, ensuring optimal washing efficiency. Our Type S sand washing machine includes all these features, with a heavy-duty screw shaft, adjustable overflow weirs, and optional hydrocyclones for fine sand recovery. When you invest in a 90-110 TPH bauxite sand washing machine in Sumatra Indonesia, these features ensure reliable, high-quality output with minimal downtime.

Indonesia's operating environment – climate, power, and logistics

Indonesia has a tropical climate with high temperatures, high humidity, and significant rainfall during the monsoon season. When you invest in a 90-110 TPH bauxite sand washing machine in Sumatra Indonesia, you must specify equipment that can withstand these conditions. Our Type S sand washing machine is built with corrosion-resistant coatings, stainless steel fasteners, and weatherproof electrical enclosures. The motor is rated for continuous operation in high-temperature environments, and the lubrication system uses high-temperature grease to maintain performance. The power supply in Indonesia is generally stable at 380V/50Hz, but voltage fluctuations can occur in remote areas; we recommend using a voltage stabiliser or soft starter to protect the equipment. Logistics are well-developed, with Sumatra's ports handling bulk cargo efficiently. Our logistics team has extensive experience shipping to Indonesia and can coordinate door-to-door delivery, including customs clearance. We also provide on-site installation supervision and commissioning support to ensure your machine is operational quickly.

Energy efficiency and operating costs – maximising your return on investment

The long-term profitability of your sand washing machine depends not only on the initial investment but also on the ongoing operating costs. Our Type S sand washing machine features a high-efficiency motor and an optimised screw design that reduces power consumption by approximately 10-15 per cent compared to conventional designs, based on our internal comparative data. With industrial electricity tariffs in Indonesia being a significant operating cost, these savings accumulate over the machine's lifetime. Wear parts – such as screw flighting and trough liners – for bauxite typically last 1,500-3,000 hours, depending on feed abrasiveness. We supply genuine replacement parts at factory prices and recommend keeping a basic spare parts kit on site to minimise downtime. By optimising both the equipment selection and operational practices, you can achieve a low cost per tonne and a fast payback period. The growing demand for washed bauxite in Indonesia, combined with the government's push for domestic processing over exports, makes investing in local washing capacity a strategic move. We provide a comprehensive cost projection with every quotation, helping you evaluate the return on investment accurately.
