Hua Sheng Ming Roll Crusher for Pea Gravel – Low Fines, High Output

Pea gravel is abundant and low-cost, making it a quality raw material for sand and gravel plants to increase output and efficiency. However, pea gravel sand making has long faced industry challenges such as excessive over-grinding, poor particle shape, high recirculation rates, and frequent equipment maintenance, limiting the resource utilization of pea gravel. A customer in Zhumadian, Henan, successfully addressed these production pain points through equipment upgrade by adopting the Hua Sheng Ming 1010 heavy-duty full-hydraulic roll crusher.

Project Overview

A customer in Zhumadian, Henan, specializes in pea gravel recycling and sand making. Previously using conventional hammer crushers for pea gravel processing, the customer faced issues including excessive over-grinding causing raw material waste, high flaky and elongated particle content failing to meet commercial sand standards, unqualified discharge requiring repeated recirculation, and high equipment failure rates with frequent maintenance.

After comparing multiple equipment options and conducting on-site evaluations, the customer selected the Hua Sheng Ming 1010 heavy-duty full-hydraulic roll crusher for pea gravel fine crushing and sand making. Hua Sheng Ming’s official case records confirm that the 1010 full-hydraulic roll crusher is suitable for pea gravel material crushing projects.

Equipment Configuration and Working Principle

The 1010 heavy-duty roll crusher operates on the inter-particle compression principle, distinct from the impact method of conventional crushers. Two high-strength wear-resistant rolls rotate in opposite directions. Pea gravel in the roll gap is subjected to sustained compressive pressure, fracturing along natural textures and mineral boundaries rather than being shattered by high-speed impact. The roll gap can be precisely adjusted for accurate discharge size control.

The equipment is powered by two 90kW motors with corresponding reducers, delivering stable power transmission for continuous pea gravel crushing operations. In a Shiyan, Hubei case, the 1010 heavy-duty roll crusher with dual 90kW motors successfully processed pea gravel to below 3mm.

Operating Parameters and Performance

Material: Pea gravel (typically below 50mm)
Discharge Size: Consistently controlled below 3mm

Hua Sheng Ming product data shows the 1010 roll crusher achieves capacities of 50-100 tons per hour. In the Shiyan, Hubei pea gravel crushing case, the equipment operated in a closed-circuit system with a 1860 vibrating screen, with oversize material returned for re-crushing. A customer in Huaihua, Hunan, after evaluation, also introduced two 1010 full-hydraulic roll crushers for pea gravel processing, achieving 60-70 tons per hour.

Key Advantages

Controlled Over-grinding – Improved Product Yield

The roll crusher uses static pressure compression rather than impact, reducing fines generation at the source and effectively improving finished sand yield. The roll crusher offers low over-grinding and high output, with roll shell average service life of approximately 2 years—far superior to the frequent replacement required by hammer crushers.

Uniform Discharge – Quality Product

The finished product features uniform particle size, rounded shape, extremely low flaky and elongated particle content, and meets engineering sand standards. The roll crusher produces sand with full particle shape and reasonable gradation.

Stable Operation – Reduced Recirculation

The roll crusher offers low energy consumption, smooth operation, and low long-term operating costs. It handles moist materials effectively without clogging. Compared to hammer crushers requiring monthly maintenance 2-3 times and quarterly hammer and liner replacements, the roll crusher features a hydraulic spring integrated balance flash protection system with minimal wear parts.

Customer Feedback

The Zhumadian customer reported that previous equipment produced excessive over-grinding, poor product quality, and frequent maintenance shutdowns. After switching to the Hua Sheng Ming 1010 heavy-duty roll crusher, over-grinding was significantly reduced, discharge size became uniform and stable, maintenance burden was noticeably reduced, and idle pea gravel was effectively utilized.

The Hua Sheng Ming 1010 heavy-duty full-hydraulic roll crusher, through its inter-particle compression principle, effectively addresses industry pain points in pea gravel sand making including over-grinding, poor particle shape, and high recirculation rates. The equipment has been deployed in multiple pea gravel sand making projects in Zhumadian, Henan; Shiyan, Hubei; and Huaihua, Hunan, providing a reliable equipment solution for pea gravel resource utilization.
