In the field of processing of construction sand and mineral powders, river pebbles, as a common hard raw material, their processing efficiency and product quality directly affect the economic benefits of the project. Choosing the appropriate grinding equipment is the key to ensuring the efficient and stable operation of the production line. This article will analyze the main models of suspension roller type grinding equipment available on the market and the influencing factors of their prices, and provide you with professional selection references based on the characteristics of river pebbles.
I. Characteristics of River Pebble Processing and Key Points for Equipment Selection
The Mohs hardness of river pebbles usually ranges from 7 to 8, featuring high wear resistance and a high silicon content. This places strict requirements on the material of the grinding components of the grinding equipment, the structural strength of the main unit, and the grinding process. Traditional Raymond mills (oscillating mills) often encounter problems such as rapid wear of the grinding rollers and grinding rings, low output, and difficulty in maintaining stable fineness when processing such materials. Therefore, modern production lines tend to prefer vertical roller mills or upgraded European-style grinding machines with more advanced structures, more mature wear-resistant technologies, and higher automation levels.
The core of the selection process should focus on the following points: 1. Processing capacity and product fineness range: it needs to match the planned production volume of the project and the purpose of the product (such as concrete aggregates, admixtures or higher value-added fillers). 2. Wear-resistant component lifespan and maintenance cost: directly related to the cost of consumable parts for long-term operation. 3. System integration and environmental performance: a system integrating drying, grinding and classification can significantly reduce investment and operational complexity, and must also meet environmental requirements.
II. In-depth Comparison of Mainstream Roller Mill Powder Production Equipment Models
At present, for the grinding of medium-hard materials such as river pebbles, the following are the main representative types of equipment available in the market:
Vertical Roller Mill Series
This is the preferred solution for processing river pebble powder with large-scale production and medium fineness requirements. It adopts the bed powdering principle, where the grinding rollers press the materials on the grinding disc. It has low energy consumption, high output, and integrates a drying function, making it highly suitable for handling materials with certain moisture content that need to be processed simultaneously.
Take our core product, the vertical roller mill, as an example. This model is our flagship product in this field. It integrates drying, grinding, powder separation, and conveying functions, focusing on three major areas: non-metallic minerals, coal powder, and slag micro-powder. The processing fineness can be flexibly adjusted within the range of 0.84 - 0.037mm (approximately 20 - 400 mesh). The single-unit output covers 10 - 400 T/H, meeting the requirements of large-scale production. The equipment adopts a new grinding device and an automated electrical control system, featuring low investment costs, low operating costs, high drying efficiency, and significant environmental protection and cleanliness advantages. For customers planning to build large-scale river pebble crushing or mineral powder production lines, the vertical mill demonstrates outstanding performance in terms of comprehensive investment return rate.
2. European version grinding machine series
As an upgraded version of the traditional Raymond mill, the European model has made comprehensive innovations in the transmission system, lubrication method and powder selection accuracy. For instance, it adopts a fully integrated bevel gear transmission and an internal lubrication system with oil inside, resulting in more powerful performance and easier maintenance. For river pebble processing projects with medium production requirements (such as 3-55 T/H), but with finer product fineness requirements (0.045-1.6 mm) or the need to produce multiple specifications of products, the European model is an extremely cost-effective choice.
3. Ultra-fine Vertical Mill and Ring Roller Micro Powder Grinding Series
When the processing target of river pebbles is ultra-fine powders of 325 mesh or above (such as for use in coatings, fillers, etc.), these types of equipment become the preferred choice. They adopt more precise grinding curves and multi-head classification technology, capable of steadily producing ultra-fine powders ranging from 650 to 3250 mesh. However, the single-unit output is relatively low (0.5 - 25 T/H), and they are suitable for processing high-value-added powders.
