Feature

Description

Primary Function

Fixed conical component in the hydrocone crusher; works with the mantle to crush medium to hard rocks in the secondary stage, producing sand and gravel with controlled particle size; suitable for mining and construction industries.

Dimensions

Various models such as Concave 2, 4, 5.5, 6.5, 7, and 8 (for 36-inch hydrocone); internal diameter approximately 80–120 cm.

Approx. Weight

800–1500 kg (depending on model and material; heavier than the mantle due to fixed structure).

Material

Manganese-molybdenum alloy steel or wear-resistant steel; durable against abrasion, pressure, and continuous impact.

Quantity per Machine

1 per hydrocone; installed on the bottom shell, can be interchanged with the mantle to switch functionality (sand making or coarse crushing).

Related Capacity

Compatible with hydrocone crushers of 100–300 t/h; output size (5–50 mm) controlled by adjusting the gap with the mantle.

Key Advantages

High durability (6–12 months in tough conditions), easy hydraulic adjustment, improved particle size quality, reduced maintenance costs, precise alignment with mantle and top shell.

The Novinsm Hydrocone Concave is one of the main parts of the hydrocone crusher, installed inside the top shell and on the mantle, which itself is mounted on the head center.

During crushing, the material is first directed into the space between the concave and the mantle. By reducing the distance between these two parts via the head center shaft, the rocks are crushed under pressure. The final size of the crushed rocks depends on this gap and its adjustment.

The concave has a standard angle that creates a V-shaped space with the mantle. The size of this angle directly affects crushing performance and speed. A smaller angle limits the input space for rocks, increases friction and wear, and changes the output size.

Choosing a high-quality concave is very important. Durable materials, precise manufacturing, and adherence to specifications increase its lifespan, improve crusher efficiency, and reduce maintenance costs.

Hydrocone Concave Features

On-site Replacement: The concave can be replaced directly at the crusher installation site.
Material Options: Available in carbon-manganese steel and manganese-molybdenum steel.
Custom Production: Manufactured according to client requirements for all models.
Machining & Finishing: Precision machining and surface finishing are possible.

Selecting a high-quality concave is critical. Durable materials, precise manufacturing, and adherence to standards enhance lifespan, improve crusher efficiency, and reduce maintenance costs.

Concave Function and Impact in Hydrocone Crushers

The concave is a crucial and influential part of the Novinsm hydrocone sand crusher. Primarily used as a secondary crusher, it can serve as a fine crusher, cobble crusher, or superior (coarse) hydrocone depending on the top shell size and mantle-concave combination. It crushes rocks into sand and gravel, producing particle sizes suitable for various applications.
