In 2022, the global sand mill market reached a size of 1.621 billion US dollars, and is expected to reach 2.009 billion US dollars by 2029, with a compound annual growth rate (CAGR) of 3.11%.
At the regional level, the Chinese market has undergone rapid changes in the past few years. In 2022, the market size was 423 million US dollars, accounting for approximately 27.00% of the global market. It is expected to reach 649 million US dollars by 2029, with a global market share of 32.30%.
From the perspective of product types, sand mills are mainly divided into horizontal sand mills and vertical sand mills. Horizontal sand mills play an important role, and with the increasing demand for high-end grinding, the share of vertical sand mills is gradually increasing.
From the perspective of product market application, the lithium battery industry has the largest market share in 2022, accounting for 22.05%, and is expected to reach 23.89% in 2029.
1. Sand grinder single machine:
The sand mill is mainly composed of a grinding device, a transmission device, a cooling device, an auxiliary device, and a control system
(1) Grinding device: It is the main working component of the sand mill, mainly including grinding elements (turbine, convex block, rod pin, etc.), fixed distance disc, spindle, grinding cylinder, medium dynamic separator, etc;
(2) Transmission device: It is the core component that ensures the normal operation of the sand mill, consisting of main shaft gearbox, main shaft, bearings, mechanical seal device, and pins and other components. It inputs the power provided by the electric motor into the grinding chamber to provide energy for material crushing;
(3) Cooling device: mainly used to cool down the sand mill chamber, consisting of cooling pipelines, chillers, pump alarm devices, etc. The cooling water continuously circulates and flows through the grinding drum and spindle for heat exchange;
(4) Auxiliary devices: including feeding system, discharging system, air pump, etc;
(5) Control system: including motor, frequency converter, pressure gauge, temperature gauge, flow meter, signal amplifier, etc.
2. Sand grinding system
The sand mill system mainly consists of a coarse grinding system, a fine grinding system, and a demagnetization system.
(1) Coarse grinding system: Its main function is to perform preliminary coarse grinding on dispersed materials, creating conditions for the next step of fine grinding. It consists of a nano ceramic sand mill, AB reciprocal switching system, control valve, coarse grinding mixing tank, and filtering iron remover.
The coarse grinding system generally uses a sand mill and 2-3 circulation tanks for ABC circulation grinding, or can be switched to single tank circulation grinding. It can ensure uninterrupted production under extreme abnormal conditions.
(2) Fine grinding system: Its main function is to further refine the material after rough grinding, making the particle size smaller and meeting the process requirements. It consists of a nano ceramic sand mill, AB reciprocal switching system, control valve, coarse grinding mixing tank, and filtering iron remover.
(3) Demagnetization system: it is mainly used to temporarily store the sanded materials for spray drying. Composed of electromagnetic iron remover, iron removal finished product tank, switching system, control valve, etc.
The Yifuli sand mill has been widely recognized in the industry for its advantages in ultrafine grinding, never clogging materials, narrow particle size distribution, cost savings of zirconium beads, improved grinding efficiency, reduced energy consumption, and optimized production line matching design. It also has rich application cases. Welcome to inquire!
