Engineering & Performance Parameters – Concave & Mantle (Hydrocone)

Section	Details
Overview	The Concave (fixed part) and Mantle (moving part) are the primary wear components of the Hydrocone crusher. They are responsible for secondary crushing and producing uniform sand and gravel (0–30 mm).
Material	Austenitic manganese steel (12–14% Mn) – Grade Mo1/Mo2; initial hardness 200 HB, work-hardened up to 550 HB.
Compatible Models	All Iranian and international Hydrocone models (H1800 – H2800 – H3800 – H4800 – H6800 – H8800) and Delta / Sandvik equivalents.
Approx. Weight	Concave: 200–1,200 kg; Mantle: 150–900 kg (depending on machine size)
Service Life	800–2,000 tons of material processed (30–50% longer than common Chinese parts; up to 70% of European OEM lifespan)
Capacity	50–800 t/h (depending on Hydrocone size and CSS adjustment)
Key Advantages	– Excellent cubical sand shape – 25–35% cost reduction vs OEM parts – High wear and impact resistance – Available in Standard and Fine/Coarse grades
Main Applications	Iron ore, granite, basalt, silica, dolomite mining; sand & gravel production; concrete and asphalt lines
Installation & Adjustment	Press-fit installation (no welding); CSS adjustable from 8–48 mm; complete replacement under 2 hours
Warranty	Genuine 12-month warranty or 1,000 operating hours (whichever comes first) + nationwide after-sales support

Key Features of Concave & Mantle

Made from high-manganese steel for exceptional wear and impact resistance, extending the crusher’s service life.
Precisely engineered conical profile for improved crushing efficiency and uniform particle size.
Capable of handling heavy loads and pressure without deformation; ideal for hard rock and high feed rates.
Fully compatible with multiple Hydrocone models, ensuring easy installation and stable operation.
Provides even force and impact distribution, reducing vibration and internal component damage.
Quick and simple installation and replacement, minimizing production downtime and increasing productivity.
Uniform wear over the component’s lifespan maintains consistent product quality.
High resistance to elevated temperature and pressure without performance degradation.
Available in various sizes and alloys to meet different crushing line requirements.

Types of Concave & Mantle

Category	Subcategory	Application / Description

	4″	Medium crushing, general applications
	5.5″	Semi-heavy crushing lines
	6.5″	Heavy crushing with high capacity
	7″	Coarse product production
	8″	Heavy-duty coarse crushing lines
By Profile	Fine	Sand production, fine output
	Medium	Standard particle size distribution
	Coarse	Primary crushing, large stones
By Usage	Sand-making	Maximum efficiency in sand production
	Large stone feed	Suitable for large, hard rocks
	Silica mines	High wear resistance
	Asphalt & concrete lines	Uniform and standard output
By Alloy	MN13 (13% Mn)	Standard operation
	MN18 (18% Mn)	Hard rock and high wear applications
	Mn-Mo	Longer life and higher strength
	Reinforced Mn	Best performance in extreme wear conditions

Buying Guide for Concave & Mantle

Identify the exact Hydrocone model (e.g., 36-2, 36-4, 36-5, 36-8) to ensure the correct conical profile and working angle.
Select the appropriate concave diameter according to intended use: sand-making or coarse crushing (e.g., 4″, 5″, 6.5″, 7″, 8″).
Hydrocones typically use two types of mantles: Mantle 2 and Mantle 4. For finer crushing (sand-making), use Mantle 2 with a smaller concave; for coarse crushing, Mantle 4 with a larger concave.
Choose high-manganese steel or Mn-Mo alloys for maximum wear and impact resistance.
Ensure the concave and mantle support CSS adjustment, as proper CSS is critical for performance, wear, and particle size quality.
Installation must be precise to maintain the conical profile and achieve uniform wear. Regular inspection (cracks, chipping) and timely replacement prolong lifespan.
Feed material should be uniform to prevent uneven wear.
Verify that the manufacturer or supplier offers technical support, warranty, and spare parts availability.
Shipping and delivery time are important due to component weight and sensitivity. Confirm with Novincsm for pricing and custom alloy or size options.

FAQ – Concave & Mantle (Hydrocone)

1. Which Hydrocone models are compatible with the concave & mantle?

Novincsm concave & mantle assemblies are manufactured for various 36-inch Hydrocone models, including 36-2, 36-4, 5.5, 6.5, 7, and 8-inch variants. When ordering, simply provide your machine model and required size, and the compatible component will be supplied.

2. What is the service life of a concave & mantle?

The lifespan depends on alloy type, operational intensity, feed material hardness, and CSS (Closed Side Setting) adjustment. Under standard conditions, Novincsm concave & mantle components offer long service life and excellent wear resistance due to high-quality manganese steel construction.

3. How do I select the correct size for the concave & mantle?

Size selection depends on the intended application (sand-making vs. coarse crushing), desired product output size, and the Hydrocone model. If unsure, you can send your machine specifications to Novincsm, and our experts will provide a free recommendation for the optimal assembly.

4. Is online ordering and fast delivery available?

Yes. Orders can be placed online, and after technical verification, the product is shipped as quickly as possible. Secure packaging, nationwide delivery, and authenticity guarantee are provided.
