Grinding media manufacturer solutions for high tonnage plants
Shandong Allstar Grinding Ball Co., Ltd. (ALLSTAR grinding balls) is a specialist grinding media manufacturer serving high tonnage mining, cement, and power generation plants. Established in 1985 and privately operated since 1999, the company produces forged grinding balls, cast grinding balls, high chrome grinding balls, grinding rods, and grinding cylpebs. Its 15,000 square metre facilities, 150 employees, and 100,000 metric ton annual capacity support large projects and reliable supply. ALLSTAR emphasises raw material testing, controlled melting and forging, batch inspection, heat treatment verification, ISO 9001 systems, and third-party inspection. Its media are used in SAG mills, ball mills, and rod mills for gold, copper, iron ore, nickel, phosphate, lead-zinc, cement, and power applications. Proven results include lower consumption and breakage at Pinto Valley Mine and sustained consumption reduction at Turkey YD Madencilik. The company positions itself as a long-term partner focused on quality, performance, and lower grinding costs.
High tonnage mining, cement, and power generation operations depend on grinding media that can deliver stable wear life, low breakage, and predictable mill performance. Shandong Allstar Grinding Ball Co., Ltd., known as ALLSTAR grinding balls, has focused on this challenge since 1985. Originally a state-owned enterprise, the company became privately operated in 1999 while retaining rigorous management standards and strict quality control. Today, ALLSTAR operates 15,000 square metres of production facilities, employs 150 people, and has an annual grinding media production capacity of 100,000 metric tons, supporting large plants and multi-site projects.
Product Range for Demanding Mills
ALLSTAR manufactures forged grinding balls from 20 mm to 150 mm, cast grinding balls from 6 mm to 150 mm, high chrome grinding balls, grinding rods from 25 mm to 140 mm in lengths from 1,500 mm to 6,000 mm, and grinding cylpebs. These products serve SAG mills, ball mills, and rod mills in mining, cement, and power generation. The product mix allows high tonnage plants to standardise supply while matching media to ore hardness, clinker grindability, mill type, and operating conditions.

Selection by Application
Grinding media selection has a direct effect on throughput, energy use, and media consumption. Larger media are generally used in the first chamber for coarse grinding, while smaller media support fine grinding in the second chamber. High chrome cast balls are widely used in cement plants and power stations. Grinding rods are mainly applied in rod mills for mineral processing. In mining, forged balls are commonly selected for wet grinding, while cast balls are often used in dry grinding. ALLSTAR works with gold, copper, platinum, iron ore, nickel, phosphate, and lead-zinc operations, as well as cement manufacturers, power plants, and industrial distributors, to recommend suitable solutions.
Quality Control and Supply Reliability
Quality control begins with raw materials. Round steel bars for forged balls and rods are sourced from large state-owned steel mills in China and are sampled and tested for chemical composition on arrival. For cast products, ferrochrome and iron scrap are proportioned and melted according to the required grade, with chemical analysis after melting. ALLSTAR uses air hammer forging, hot rolling, advanced coated-sand shell molding, and automated production lines. Samples are taken from each batch, and finished products are tested after heat treatment. The company maintains ISO 9001 quality management and supports verification through SGS, BV, and TUV inspection services. It has also been recognised as a High and New Technology Enterprise and a Specialized, Sophisticated, Distinctive and Innovative Enterprise.
Proven Performance in High Tonnage Operations
At Pinto Valley Mine in the USA, a nearly six-month comparative trial placed ALLSTAR high chrome grinding balls in one ball mill and another supplier's media in the other. ALLSTAR consumption remained stable at 0.56 to 0.59 kg per tonne of run-of-mine ore, with a breakage rate of only 0.2 percent. The other supplier reached 0.68 kg per tonne and a breakage rate close to 3 percent. The competitor mill also recorded more than 70 tonnes per hour lower output and over 5 percentage points lower grinding fineness. The customer subsequently converted the second mill to ALLSTAR media. Daily processing capacity reached 53,000 tonnes, exceeding the 50,000-tonne design by 3,000 tonnes, and the mine has purchased more than 48,000 tonnes of ALLSTAR grinding media.
In the cement industry, Turkey YD Madencilik operated a combined roller press and ball mill system with difficult-to-grind slag and coarse fly ash. After replacing grinding balls in both mills with ALLSTAR products in 2016, combined consumption fell from 84.80 g/t in 2016 to 31.93 g/t in 2018. The improvement was sustained, reaching 25.66 g/t in 2025, approximately 69.7 percent below the 2016 baseline.
A Practical Partner for Long-Term Value
High tonnage plants need more than specified hardness or chemistry. They need consistent quality, dependable delivery, lower overall grinding costs, and stable mill operation. ALLSTAR combines manufacturing capacity, strict quality control, and application experience to help customers reduce media consumption and breakage while improving grinding efficiency and production capacity. Its business philosophy is to manufacture high-quality products, act as a reliable supplier, and build long-term partnerships rather than focus on single transactions. For large-scale mining, cement, and power operations, ALLSTAR grinding balls offers a practical grinding media solution backed by proven performance and responsible service.
