Analysis of small jaw crusher price
Mini jaw crushers can be purchased for as little as a few hundred dollars. But due to various factors, the price of the small jaw crusher will also fluctuate. Then what are the factors affecting the price?

1. The quality analysis
Quality is a key factor in determining a piece of equipment, which is mainly related to the choice of the manufacturer. Different manufacturers'production processes and manufacturing materials are different, which directly leads to different input costs of equipment, so the price is naturally very various.

2. Supply and demand analysis
The relationship between supply and demand is also an important factor affecting price fluctuations, which is also derived from the laws of the market.

When the supply exceeds demand, the price of the equipment will be lower; when the supply is less than demand, the price of the equipment will naturally be higher.

3. Manufacturer analysis
We all know that there are two main types of suppliers, one is a direct-supply manufacturer that combines production and sales; the other is an indirect supplier that sells and earns a speculative profit.

As a result, it is conceivable that the former has a price concession because it can provide the factory price, and the latter tends to increase the price on the basis of the ex-factory price in order to obtain more profits.

In view of the great demand of users for mini crushers, FTM has developed and manufactured a variety of small jaw crushers to meet the different crushing requirements of customers..
