Since 2005, the mission of Hangzhou Watanabe Agricultural Stone Crusher Co., Ltd. has been to lay a solid foundation for global infrastructure construction and mining development by providing efficient, reliable, and innovative stone crushing solutions. We firmly believe that outstanding equipment is the core driving force behind human progress. Our vision is to become the most trusted partner in the global stone crushing equipment field, turning every stubborn stone into a source of value creation.

Our Story

2005-2009

Foundation | Starting by Solving a Pain Point
The story begins with a frontline equipment maintenance worker, who is our founder. In his daily work, the thing he faced most often was not the hard rock, but the crushers that frequently shut down due to worn core components. The anxious looks from customers due to production stoppages were the greatest driving force for change. In 2005, he led several experienced technicians to start tackling the technology of wear parts like jaw plates and hammer heads in a rented workshop. Our goal was simple and pure: to make more wear-resistant components with a longer lifespan.

2009-2014

Taking Root | The Birth of the First Complete Machine
With a solid reputation in the field of wear parts and a deep understanding of crushing principles, we were no longer satisfied with merely playing a ‘supporting role.’ In 2009, we successfully assembled and sold our first self-designed heavy-duty hammer crusher. This machine underwent the harshest test at a quarry in Zhejiang, performing beyond the client’s expectations. In the following years, we focused on the research, development, and manufacturing of medium and small crushing equipment. By collecting extensive frontline feedback and rapidly iterating on our products, our equipment established a foothold in the regional market for being ‘sturdy and durable.’

2014-2019

Growth | Building Systems and Expanding Product Lines
With the country’s infrastructure construction entering the fast track, market demand has surged. In 2014, we relocated to our own industrial park, introducing CNC machining centers and automated welding robots, achieving a leap from ‘workshop-style’ production to modern manufacturing. At the same time, we established a complete R&D, quality inspection, and supply chain system. Our product line expanded from a single impact crusher to include jaw crushers, cone crushers, sand-making machines, and other series, enabling us to provide customers with more comprehensive crushing solutions.

2019-2024

Innovation | Towards Intelligence and Sustainability
Facing intense market competition and increasingly strict environmental requirements, we embarked on a secondary entrepreneurial journey centered on ‘intelligence’ and ‘green’ development. We launched a new generation of products equipped with intelligent lubrication systems and remote monitoring modules, helping customers achieve predictive maintenance. We actively explored technologies such as noise control and dry dust removal to make crushing operations more environmentally friendly. During this period, our equipment began to be exported in bulk to international markets such as Southeast Asia and the Middle East.

2024–Present

Transcend | Define the future, become the leader in solutions
Standing at a new starting point, our role has evolved from a ‘equipment manufacturer’ to a ‘full-process productivity solution provider.’ We not only offer high-performance main equipment, but also provide one-stop services from on-site surveying, process design, and equipment selection to installation, commissioning, operational training, and lifetime maintenance. We are exploring cutting-edge areas such as mobile crushing stations and the recycling of construction waste together with industry partners, committed to using our expertise to create maximum value for every customer project.
Agricultural Rock Crusher Production Base
This journey from a workshop to a leading enterprise confirms our original intention: we not only understand machines, but also understand your business. This DNA, born from practice and perfected through innovation, is the cornerstone of our expertise and experience.

Our Core

Technology Research and Development
Our R&D is rooted in a profound understanding of the principles of crushing and countless on-site failure analyses. We reject the industry convention of ‘good enough’ and adhere to a philosophy of ‘over-engineering.’ For example, for the rotor, a core component, we not only use an integral forging process but also employ dynamic balance calibration and finite element analysis to identify and eliminate stress concentration points in advance. This ensures that our crushers can not only operate stably under the intense impact of granite and basalt but also efficiently convert the impact energy into crushing work, achieving an optimal balance between energy consumption and output.
Manufacturing Quality
Reliability stems from an obsession with millimeter-level precision and process consistency. In our smart factory, robotic welding ensures that every weld meets or exceeds strict standards for depth and strength; our temperature-controlled assembly centers guarantee that critical fit components such as bearings and bushings are assembled with consistent precision. We firmly believe that excellent performance is manufactured, not inspected. Therefore, we have established a full-process quality control system covering everything from raw material intake to finished product shipment, implementing over a dozen key quality checkpoints to ensure that every piece of equipment delivered to you possesses the outstanding quality required to withstand thousands of hours of rigorous challenges in the future.
Service Philosophy

We deeply understand that the true value of a piece of equipment lies in its productivity throughout its entire lifecycle. Therefore, our services begin even before the sale, offering you optimal selection through free on-site condition analysis; continue throughout every day of the equipment’s operation, with 24/7 remote support and predictive maintenance alerts to prevent potential failures before they occur; and extend across the entire lifecycle of the equipment, ensuring you can quickly obtain genuine parts when needed through our global spare parts network. What we sell is not just a machine, but a continuous guarantee of productivity and a lifelong partnership committed to growing together.

Customer Success Case

The original production line of Hongji Building Materials in Quzhou, Zhejiang, used a traditional spring cone crusher to process high-hardness granite. This not only consumed a lot of energy but also frequently blocked due to inconvenient adjustment of the discharge port, resulting in an average daily effective production time of less than 14 hours, with finished products having plate-like content as high as 18%, severely affecting the selling price.

Solution: We replaced the core crushing section with an HPT500 multi-cylinder hydraulic cone crusher equipped with a hydraulic automatic cavity cleaning system and laminated crushing chamber, achieving iron-overload protection and one-key adjustment of the discharge port.

Quantified results:
Overall production line efficiency increased by 30%, with daily effective production time stabilized at over 18 hours.
The plate-like content of finished aggregates was reduced to below 10%, increasing the market price of products by about 5 yuan per ton.
The hydraulic system reduced maintenance time by 60%, significantly lowering labor costs.

The main mining area of Yongxin Mining in Anshan, Liaoning, consists of extremely wear-resistant basalt. The original manganese steel jaw plates of the jaw crusher needed to be replaced after crushing an average of 300,000 tons of material. The annual spare part cost for just the jaw plates exceeded 400,000 yuan, and frequent replacements severely affected production continuity.

Solution: We customized a JC series ultra-heavy-duty jaw crusher for them, equipped with specially designed jaw plates made using the “super-tough high-chrome composite casting technology,” giving the jaw plate surface extremely high hardness while maintaining toughness at the core to prevent breakage.

Quantified Results:
The service life of a single set of customized jaw plates exceeded 1.2 million tons, four times that of the original equipment.
By reducing downtime and avoiding spare part replacements, this directly saved the customer over 600,000 yuan in annual production costs.

The project department of a certain section of the China-Laos Railway is located in a tropical rainforest, where the site is humid and rainy, and local technical support is limited. The reliability, anti-corrosion capability, and after-sales response speed of crushing equipment are the ultimate tests.
Solution: We not only provided the HST560 single-cylinder hydraulic cone crusher with special anti-rust treatment for tropical climates, but also innovatively equipped it with an ‘Intelligent Cloud Platform’ to enable remote monitoring of equipment data and fault warnings. At the same time, we established a dedicated spare parts warehouse at the project site.
Quantifiable Results:
During the first 18 months of the project, the equipment achieved over 98% trouble-free operation.
The cloud platform provided early warnings of two potential bearing overheating incidents, preventing unplanned downtime.
The project department awarded us the title of ‘Optimal Supplier for Key Equipment.’
