Double-Roll Sand Making Machine
High-Pressure Extrusion Sand Making Equipment | Efficient for Medium-Soft Materials
Product Overview
The double-roll sand making machine (also known as twin-roll sand maker) is a high-efficiency equipment developed by Shandong Hengtai Intelligent Manufacturing specially for sand making of medium-soft materials. It crushes materials through high-pressure extrusion of 50-200MPa generated by the opposite rotation of double rolls, and is widely used in cement, chemical, electric power, metallurgy, building materials and other industries.
The equipment is suitable for medium-hardness materials such as river pebbles, limestone, gangue, etc. The discharge particle size is adjustable (0.5-40mm), with large crushing ratio and low energy consumption. It supports crushing of both dry and wet materials, and the finished product has uniform particle size. It is the preferred equipment for small and medium-sized sand making projects and material pretreatment, and has won recognition from global customers for its simple structure and convenient maintenance.
Applicable Materials & Application Scenarios
Applicable Materials: Medium-hardness materials with compressive strength ≤ 150MPa, such as river pebbles, limestone, gangue, shale, gypsum, slag, etc.
- Small & Medium-Sized Mechanized Sand Production
- Cement Industry Raw Material Pretreatment

Core Performance Features
High-Pressure Extrusion Crushing & Uniform Particle Shape
The opposite rotation of double rolls generates high-pressure extrusion, which fully crushes materials. The finished product has uniform particle size and reasonable gradation, meeting the requirements of construction sand and aggregate processing.
Dry & Wet Dual-Use & Wide Scene Adaptability
Supports crushing of both dry and wet materials without additional drying or humidification treatment, suitable for operation in rainy, high-humidity areas and dry environments.
Flexible Adjustment & Controllable Capacity
The grate gap is adjusted through hydraulic or wedge adjustment system. The discharge particle size is adjustable from 0.5-40mm, and the capacity covers 20-250t/h, adapting to production needs of different scales.
Low Noise, Energy Saving & Easy Maintenance
The structure is simple and compact, with low operation noise. The energy consumption is reduced by 20% compared with traditional sand making machines; the wearing parts are roller surfaces, which are easy to replace and require little daily maintenance.
